Well... I am trying to create an application using the TTS Engine.
I can already make it, work, no problem. However I need my buttons to be dinamic, they will come from a database.
**So far you guys have helped me a lot, since now I can do it thanks to the tips I got from you guys.**
**Well.. now I am stuck again.**
Every new button that I create I attach an OnClickListener so it can start the TTS and speak something.
However it's an inner method, so, when I try to run the code below, it gives me a NullPointerException when it tries to "speak" using the TTS. I know the TTS object is out of context, so, **How can I solve this?**
Below the code. It's a little big since I wanted to include everything:
PLEASE JUMP TO THE "HERE IS MY PROBLEM!!!" comment so you guys can see exactly where my problem is. I know where it is, but I don't know how to solve it =(
Any help is appreciatted! =)
Code:
public class LivoxTesteActivity extends Activity implements OnInitListener{
/** Called when the activity is first created. */
private int MY_DATA_CHECK_CODE = 0;
public TextToSpeech tts;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
LinearLayout lgeral = new LinearLayout (this);
lgeral.setOrientation(LinearLayout.VERTICAL);
lgeral.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT, 1f));
String array[][] = {{"Comer","eat", "Eu quero comer", "1"},
{"Abraço","hug", "Eu quero um abraço", "2"},
{"Assustado","afraid", "Eu estou com medo", "3"},
{"Beber","drink", "Eu quero beber", "4"}};
int x = array.length;
int qtdeLinhas = 2;
for (int j = 0; j < qtdeLinhas; j++) {
LinearLayout l1 = new LinearLayout (this);
l1.setOrientation(LinearLayout.HORIZONTAL);
l1.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT, 1f));
FrameLayout fl;
for (int i = 0; i < array.length; i++) {
fl = (FrameLayout)LayoutInflater.from(getBaseContext()).inflate(R.layout.framelayoutstyle, l1, false);
TextView textoEscrito;
textoEscrito = (TextView)LayoutInflater.from(getBaseContext()).inflate(R.layout.textviewstyle, fl, false);
textoEscrito.setText(array[i][0]);
final String texto = textoEscrito.getText().toString();
final String textoFalar = array[i][2];
ImageButton btn;
btn = (ImageButton)LayoutInflater.from(getBaseContext()).inflate(R.layout.imagebuttonstyle, fl, false);
btn.setImageResource(this.getResources().getIdentifier("drawable/" + array[i][1], null, this.getPackageName()));
btn.setOnClickListener(new Button.OnClickListener(){
public void onClick (View v){
Toast.makeText(getBaseContext(), texto, Toast.LENGTH_SHORT).show();
//*******************************
//HERE IS MY PROBLEM!!!
//*******************************
tts.speak(txtFl, TextToSpeech.QUEUE_ADD, null);
//*******************************
//WHEN I TRY TO RUN THE ABOVE IT GIVES A NULLPOINTEREXCEPTION!!!
//*******************************
}
});
fl.addView(btn);
fl.addView(textoEscrito);
l1.addView(fl);
}
lgeral.addView(l1);
}
setContentView(lgeral);
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == MY_DATA_CHECK_CODE) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
// success, create the TTS instance
tts = new TextToSpeech(this, this);
}
else {
// missing data, install it
Intent installIntent = new Intent();
installIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installIntent);
}
}
}
@Override
public void onInit(int status) {
if (status == TextToSpeech.SUCCESS) {
}
else if (status == TextToSpeech.ERROR) {
}
}
@Override
public void onDestroy() {
if (tts != null) {
tts.stop();
tts.shutdown();
}
super.onDestroy();
}
}
By the way... the method Toast.makeText(getBaseContext(), texto, Toast.LENGTH_SHORT).show(); works fine. I believe that's because the Toast is a static class.
So, maybe the solution is to create a static class with the method to speak? Ideas? How can I do it?

Moving to Q&A
Hi, this is actually 2 questions.
I have a list of items stored in one string array and a list of the collections those items are in stored in a second string array.
I want the user to be able to search for an item and see in which collection it exists.
I have managed to do this in a less-than-elegant way by simply combining the 2 string arrays into one and using a ListView with a EditText with a TextWatcher to filter the results. This all works but the result is not so eye-pleasing. I use this to make the distinction between item and collections:
Code:
<item>ITEM \r\n -> COLLECTION(S)
when defining the string array.
As I said, it works but I would like the COLLECTION(S) to be formatted differently from the ITEM. Is this possible in a ListView?
This is my current code:
Code:
public class Search extends Activity {
/** Called when the activity is first created. */
private ListView lv1;
private EditText ed;
private String[] lv_arr;
private ArrayList<String> arr_sort= new ArrayList<String>();
int textlength=0;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.search);
lv1=(ListView)findViewById(R.id.listView1);
ed=(EditText)findViewById(R.id.editText1);
lv_arr = getResources().getStringArray(R.array.all_cont);
lv1.setAdapter(new ArrayAdapter<String>(this, R.layout.row , lv_arr));
ed.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
}
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
public void onTextChanged(CharSequence s, int start, int before,
int count) {
textlength=ed.getText().length();
arr_sort.clear();
for(int i=0;i<lv_arr.length;i++)
{
if(textlength<=lv_arr[i].length())
{
if(ed.getText().toString().equalsIgnoreCase((String) lv_arr[i].subSequence(0, textlength)))
{
arr_sort.add(lv_arr[i]);
}}}
lv1.setAdapter(new ArrayAdapter<String>(Search.this, R.layout.row , arr_sort));
}
});
}}
As a second solution that looks more elegant, I used a SimpleAdapter to put the 2 original string arrays in the ListView like this:
Code:
public class Search extends ListActivity {
private String[] l1;
private String[] l2;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.seach);
ArrayList<Map<String, String>> list = buildData();
String[] from = { "name", "packs" };
int[] to = { android.R.id.text1, android.R.id.text2 };
SimpleAdapter adapter = new SimpleAdapter(this, list, android.R.layout.simple_list_item_2, from, to);
setListAdapter(adapter);}
private ArrayList<Map<String, String>> buildData() {
l1 = getResources().getStringArray(R.array.items);
l2 = getResources().getStringArray(R.array.packs);
Integer i;
int to = l1.length;
ArrayList<Map<String, String>> list = new ArrayList<Map<String, String>>();
for(i=0;i < to;i++){
list.add(putData(l1[i], l2[i]));
}
return list;
}
private HashMap<String, String> putData(String name, String packs) {
HashMap<String, String> item = new HashMap<String, String>();
item.put("name", name);
item.put("packs", packs);
return item;
}
}
This looks a lot better but I can't figure out how to make use of the EditText to filter the results.
Any help is welcomed!
Hey!
I read your post and I think it would be better to make a class like this:
Code:
public class ListItem
{
public String itemName;
public String collectionName;
}
And then in your Search activity you can Make a single ArrayList of the type ListItem. Populate this array in a way similar to how you are populating the ArrayList of the HashMaps.
Now for setting the ListAdapter you'll have to make a custom view for each row of the list(this custom row could contain two text views, one for the item name and the other for the collection and you can give them their own formatting), and then subclass the ArrayAdapter class and override its getView method.
Heres a couple of links that might be helpful:

Thanks once more. I looked over the links and I think I have an idea of how to adapt it to my app. Will try it tomorrow and let you know
Yeah. Let me know if it worked.

I feel like my head is exploding.
I did what you said but I still have some issues. Here's what I did:
1. Created a new class, Icons:
Code:
public class Icons {
public String icon;
public String title;
public Icons(){
super();
}
public Icons(String icon, String title) {
super();
this.icon = icon;
this.title = title;
}
}
Created a new XML for the style of the ListView:
Code:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<TextView
android:id="@+id/icon_name"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="3dp"
android:textSize="18sp"
android:textColor="#ffffff"
android:textStyle="bold" />
<TextView
android:id="@+id/in_pack"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_margin="8dp"
android:textSize="12sp" />
</LinearLayout>
created a new Adapter:
Code:
public class IconsAdapter extends ArrayAdapter<Icons>{
Context context;
int layoutResourceId;
Icons data[] = null;
public IconsAdapter(Context context, int layoutResourceId, Icons[] data) {
super(context, layoutResourceId, data);
this.layoutResourceId = layoutResourceId;
this.context = context;
this.data = data;
}
@Override
public View getView(int position, View convertView, ViewGroup parent) {
View row = convertView;
IconsHolder holder = null;
if(row == null)
{
LayoutInflater inflater = ((Activity)context).getLayoutInflater();
row = inflater.inflate(layoutResourceId, parent, false);
holder = new IconsHolder();
holder.txtIcon = (TextView)row.findViewById(R.id.icon_name);
holder.txtTitle = (TextView)row.findViewById(R.id.in_pack);
row.setTag(holder);
}
else
{
holder = (IconsHolder)row.getTag();
}
Icons icons = data[position];
holder.txtTitle.setText(icons.title);
holder.txtIcon.setText(icons.icon);
return row;
}
static class IconsHolder
{
TextView txtIcon;
TextView txtTitle;
}
}
Modified my Search class like this:
Code:
public class Search extends Activity {
private ListView listView1;
private String[] l1;
private String[] l2;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.seach);
l1 = getResources().getStringArray(R.array.items);
l2 = getResources().getStringArray(R.array.packs);
Integer i;
int to = l1.length;
// for(i=0;i < to;i++){}
Icons Icons_data[] = new Icons[]
{
new Icons(l1[0], l2[0]),
new Icons(l1[1], l2[1]),
new Icons(l1[2], l2[2]),
new Icons(l1[3], l2[3]),
};
IconsAdapter adapter = new IconsAdapter(this,
R.layout.row, Icons_data);
listView1 = (ListView)findViewById(R.id.listView1);
View header = (View)getLayoutInflater().inflate(R.layout.row, null);
listView1.addHeaderView(header);
listView1.setAdapter(adapter);
}
}
Up until now, everything works (almost) great. Only thing I can't do is figure out how to assign the items in the Icons_data[] array automatically (my for(...) statement doesn't seem to want to fit anywhere). Format looks good and manually inserting data does what it's supposed to. Still need to figure out the automatic data inserting thing...my arrays have 100-150 elements
What I also can't figure out is how the hell to perform the filtering/search on this new special Array... I tried using the old method with the TextWatcher on an EditText field but can't seem to be able to adapt this part:
Code:
public void onTextChanged(CharSequence s, int start, int before,
int count) {
textlength=ed.getText().length();
[B][U]arr_sort.clear();[/U][/B]
for(int i=0;i<to;i++)
{
if(textlength<=l1[i].length())
{
if(ed.getText().toString().equalsIgnoreCase((String) l1[i].subSequence(0, textlength)))
{
[B][U]arr_sort.add(l1[i]);[/U][/B]
}
}
}
[B][U]lv1.setAdapter(new ArrayAdapter<String>(Search.this, R.layout.row , arr_sort))[/U][/B];
}
});
ed is the EditText item. I guess I would need to make arr_sort of the type Icons[] and then change the Bold, Underlined lines to something...but no idea what... Is it even possible to do it like i'm doing it? Or should I look for another method to sort it?
Hey I modified your search class:
Code:
public class Search extends Activity {
private ListView listView1;
// Note: I've removed the two String[] class members cause we are going
// store this data in a single Icons[] member
private Icons[] iconsData;
private ArrayList<Icons> arr_sort; // Note: Changed the type of arr_sort
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.seach);
// We'll create two local String[] variables to assemble the data
String[] l1 = getResources().getStringArray(R.array.items);
String[] l2 = getResources().getStringArray(R.array.packs);
// get the total number of icons
int totalIcons = l1.length;
// Allocate the data for the Icon[] array
iconsData = new Icons[totalIcons];
// Now to populate the Icon array
for (int i = 0; i < totalIcons; i++)
{
iconsData[i] = new Icons(l1[i], l2[i]);
}
// Rest remains the same
IconsAdapter adapter = new IconsAdapter(this,
R.layout.row, iconsData);
listView1 = (ListView)findViewById(R.id.listView1);
View header = (View)getLayoutInflater().inflate(R.layout.row, null);
listView1.addHeaderView(header);
listView1.setAdapter(adapter);
}
}
Now you don't need to change the sorting method. Just slight modifications to fit the data structuring is all that is needed.
Code:
public void onTextChanged(CharSequence s, int start, int before, int count)
{
textlength = ed.getText().length();
arr_sort.clear();
for(int i = 0 ; i < to; i++)
{
if(textlength <= iconsData[i].icon.length()) //Note: l1 becomes iconsData[i].icon
{
if(ed.getText().toString().equalsIgnoreCase((String) iconsData[i].icon.subSequence(0, textlength)))
{
arr_sort.add(iconsData[i]); // Note: we'll store iconsData[i] if a match is found
}
}
}
lv1.setAdapter(new IconsAdapter(Search.this, R.layout.row , arr_sort.toArray()));
}
Haven't tested it. So watch out for some possible errors.
I can't thank you enough but I still need your help.
The first part works (modifications to the Search class).
Now, In the same class, after that part, I add the filtering part:
Code:
ed=(EditText)findViewById(R.id.editText1);
ed.addTextChangedListener(new TextWatcher() {
public void afterTextChanged(Editable s) {
}
public void beforeTextChanged(CharSequence s, int start, int count, int after)
{
}
public void onTextChanged(CharSequence s, int start, int before, int count) {
int textlength = ed.getText().length();
arr_sort.clear();
for(int i=0;i<[B][I]totalIcons[/I][/B];i++)
{
if(textlength <= iconsData[i].icon.length()) //Note: l1 becomes iconsData[i].icon
{
if(ed.getText().toString().equalsIgnoreCase((String) iconsData[i].icon.subSequence(0, textlength)))
{
arr_sort.add(iconsData[i]); // Note: we'll store iconsData[i] if a match is found
}
}
}
listView1.setAdapter(new IconsAdapter(Search.this, R.layout.row , [U][B](Icons[])[/B][/U] arr_sort.toArray()));
}
});
}
}
I had to make 2 changes in order for it not to give any errors. First, I changed the "to" in the for statement to "totalIcons" since that's actually the number we need and "to" was not defined. When I did this I also had to change "totalIcons" to final int since I had this error:"Cannot refer to a non-final variable totalIcons inside an inner class defined in a different method"
Also, I had to add the (Icons[]) at the end because of this error: "The constructor IconsAdapter(Search, int, Object[]) is undefined". The suggested fixes was changing the constructor for IconsAdapter, adding a new constructor or adding the (Icons[]) thing.
Now I have no errors in Eclipse but when I run the app and try to type something in the EditText box the app crashes...I get these errors:

Sorry about the previous untested code. I was in a rush to go somewhere but I saw you online and thought that it'd be better if I replied.
Anyways, I think the problem is that "totalIcons" is a local variable. So remove the final keyword. And in the for loop in the TextWatcher's onTextChanged method instead of using totalIcons use the length property of iconsData:
Code:
for (int i = 0; i < iconsData.length; i++)
Should fix the runtime error
First off, please do all the things you have to do and don't waste your time with me. I really really appreciate you trying to help me so if you don't have time for this, it's absolutely no problem.
Now, the runtime errors are still there after the change

Can you paste line 70 of Search.java?
Wait are you doing this in onCreate?
Code:
arr_sort = new ArrayList<Icons>();
That's what I was looking for (actually how to enable line numbers in Eclipse )
here it is:
Code:
arr_sort.clear();
Yep. We aren't creating arr_sort. So its a null pointer.
Do this somewhere in onCreate
Code:
arr_sort = new ArrayList<Icons>();
ok, that solved that issue. now the problem is with this:
Code:
listView1.setAdapter(new IconsAdapter(Search.this, R.layout.row, (Icons[]) arr_sort.toArray()));
What error/exception do you get?
04-12 20:17:26.663: E/AndroidRuntime(1205): FATAL EXCEPTION: main
04-12 20:17:26.663: E/AndroidRuntime(1205): java.lang.ClassCastException: [Ljava.lang.Object;
04-12 20:17:26.663: E/AndroidRuntime(1205): at mmarin.iconpack.manager.Search$1.onTextChanged(Search.java:84)
I guess that the arr_sort.toArray() creates an Object[] but we need a Icons[] resource for the IconsAdapter.
Am I close?
Yea you are right
One quick and ugly solution I can think of is maybe creating an Icons array right after the search and then filling it with all the items in the arraylist. This happens right before you are setting the adapter
Code:
Icons[] data = new Icons[arr_data.size()];
for (int i = 0; i < arr_data.size(); i++)
{
data[i] = arr_data.get(i);
}
listView1.setAdapter(new IconsAdapter(Search.this, R.layout.row, data));
This should work but it isn't really a good solution =/
Quick and ugly works for me! You're 3 for 3!
You get a big special thanks in my App!!!
Once more, thank you and probably I will ask for your help again in a short while, with another issue I can't figure out.
It will probably be about getting a market link for an app through the Share menu in the Play Store and using that information to send an e-mail - but I will try to figure it out for myself . I already found how to get my app in the "Share" menu in the Play Store and also (possibly) how to save that information to a string. Now i have to find out how to actually get my app to start a certain Activity when it is started by the Play Store app. Will do that over the weekend
Sure! I'll be happy to help out with whatever little bit know!
Does anyone know which jar files and smali files/codes( lines) for adding music control and long press back button to kill apps ?

Hello,
Recently I started working on bluetooth chat app for my final year project. I took the example coding available in the sample app in Eclipse and trying to improve it. Now I'm trying to insert 2 new functions into it, 1 - the upload button for uploading any files, 2 - bubble chat interface.
I am a beginner at android programming. I tried exploring draw 9 patch for the bubble patch. Somehow I get the bubble chat done, but not perfectly. I can make it send & receive with the same bubble style. What I'm trying to do is, receive message will show in Green bubble while send message will show Yellow Bubble. I tried the getView() method but didn't understand any of it.
As for the upload button, I'm having problem at the uploading part. I get the selecting the file part done, but I don't know how to make it automatically send the file after it being selected. I tried Googling and most of the result show Image upload. Thanks for those image upload tutorial, I get as far as choosing the file. As for uploading it(sending the file to the other paired device), I'm completely clueless...
The part that I'm having problem I highlight it with red color.
Here's my coding(technically it isn't my coding, it the sample coding with minor modification):

I'm not sure how to code for arduino. But the part how to access through a button click, i have an idea about that.
you can just open a sample bluetooth chat in eclipse, but instead of set the page auto open. just create a new main page, and add a button then, just "hyperlink" it to the bluetoothchat.
to navigate between pages using a button, i'm sure there's tons of tutorial available in google or you can just search "cornboyz" in youtube. that the best tutorial i followed back when i'm still doing android programming. I can't help you much in coding. but i know where you're getting at. Its been 2 years, last i explore android programming.
so. sorry

thanks kuronatsu for your help
Sorry for my bad english, but i have problem and can't figure it out..
I have custom listview in my fragment for getting products from JSON array. And I have 3 ImageButtons in every listview row;
Plus Button(+), Minus Button(-) and Remove Button(X)..
So when i click each button, its calling JSON request for update product's piece number, getting new datas from response and repopulate array list.
Everything ok but, when I click that buttons faster, it seems there is 1 sec delay between multiple requests even first volley request has already done before.
Here is my JSON method in TableAdapter.java
Code:
[SIZE="3"]public void JSON(final int position, final int process) {
if (inProgress==false) {
dialog = new ProgressDialog(myContext);
dialog.setMessage("Updating.....");
dialog.show();
inProgress = true;
System.out.println("**** Now request is beginning............");
final int rowID = tableModelList.get(position).getID();
final int treeID = tableModelList.get(position).getAna_dal();
final float price = tableModelList.get(position).getBFiyat();
final int quantity = tableModelList.get(position).getAdet();
final int print = tableModelList.get(position).getYazdimi();
final String insertUrl = "This is URL for getting json array";
Map<String, String> parameters = new HashMap<>();
parameters.put("tableID", "" + getTableId);
parameters.put("rowID", "" + rowID);
parameters.put("treeID", ""+treeID);
parameters.put("process",""+process);
parameters.put("quantity",""+quantity);
parameters.put("price",""+price);
parameters.put("print",""+print);
CustomRequest jsObjRequest = new CustomRequest(Request.Method.POST, insertUrl, parameters, new Response.Listener<JSONObject>() {
@Override
public void onResponse(JSONObject response) {
try {
JSONArray getOrders = response.getJSONArray("order");
Gson gson = new Gson();
tableModelList.clear();
for (int i = 0; i < getOrders.length(); i++) {
JSONObject order = getOrders.getJSONObject(i);
TableModel tableModel = gson.fromJson(order.toString(), TableModel.class);
tableModelList.add(tableModel);
}
mAdapter.notifyDataSetChanged();
System.out.println("**** onResponse: Request is done............");
System.out.println("**** JSON: "+response.toString());
dialog.cancel();
inProgress = false;
} catch (JSONException e) {
e.printStackTrace();
}
}
}, new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError response) {
Log.d("Response: ", response.toString());
inProgress = false;
}
});
requestQueue.add(jsObjRequest);
}
}[/SIZE]
Dialog is showing when request beginning and canceling when request is done. But as I said, when I click faster, there is a delay between multiple requests even first request has already done. I'm saying 1 sec, because 2nd request is beginning after 1 sec exactly, no matter how I clicking fast. I can't figure it out..
I tested fast clicks to showing toasts with random numbers and it's working fine. But when I testing with JSON method, there is a weird delay.
I have SwipeRefreshLayout and ScrollView in my fragment. I'm using Volley with singleton.
Here is video to showing what my problem is;
Here is Logcat output for every click
Every fast click has returning success json output, but nothing change instantly on the screen..
Thanks for your help.
