Hi,
I searched for a part to ask questions abut android programing but cant find so I posted here,I hope I can find my answer
I am new with android programing and I have a problem with expandable list view
I pupulate my data to an expandable list view with SimpleExpandableListAdapter and every thing is good..The only think I want is to findout which Items is selected by user..I searched but Cant fine a working method to do this
here Is my SimpleExpandableListAdapter
Code:
SimpleExpandableListAdapter expListAdapter =
new SimpleExpandableListAdapter(
this,
groupData,
android.R.layout.simple_expandable_list_item_1,
new String[] { "grup"},
new int[] { android.R.id.text1 },
childData,
R.layout.database_list_item,
new String[] { parser.KEY_CatName, parser.KEY_PoetID, parser.KEY_DownloadUrl,parser.KEY_PubDate,parser.KEY_FileSizeInByte,"Status"},
new int[] { R.id.chk_database_list_item,R.id.txt_database_poet_id,R.id.txt_database_download_link,R.id.txt_database_pub_date,R.id.txt_database_size,R.id.txt_database_status }
);
and here Is setOnChildClickListener but It dont do anything
Code:
ExpandList.setOnChildClickListener(new ExpandableListView.OnChildClickListener() {
@Override
public boolean onChildClick(ExpandableListView arg0, View v, int arg2,
int arg3, long arg4) {
Log.i("setOnChildClickListener", "setOnChildClickListener");
TextView down_link = (TextView) v.findViewById(R.id.txt_database_download_link);
TextView poet_id = (TextView) v.findViewById(R.id.txt_database_poet_id);
String down_linkString;
String poet_idString;
SparseBooleanArray choices = arg0.getCheckedItemPositions();
StringBuilder choicesString = new StringBuilder();
for (int i = 0; i < choices.size(); i++)
{
//added if statement to check for true. The SparseBooleanArray
//seems to maintain the keys for the checked items, but it sets
//the value to false. Adding a boolean check returns the correct result.
//ArrayList<String> Items_for_download = new ArrayList<String>();
if(choices.valueAt(i) == true)
choicesString.append(poet_id.getText().toString()).append(" ");
}
Log.i("selected", choicesString.toString());
return false;
}
});
Thanks for your helps

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
Hello guys first of all I'm new here so i hope i make everything correct and I'm in the right section.
I just searched for the Stock S3 Gallery (the same like Note 2 with Gallery Flow Effect) but I couldn't find somehting that runs on AOSP Roms, so I just googled a little bit and found these Code (Source was stackoverflow.com, sorry but I can't post the links because Forum Rules with 10 Posts).
Code:
gal_caterories.setAdapter(new CategoryPreferenceAdapter (context,
response.customOfferPojo.offerAvailableCategories,1));
public class CategoryPreferenceAdapter extends BaseAdapter {
private Context mContext;
private LayoutInflater mInflater;
public static List<String> thumbnailsselection;
private ViewHolder holder = new ViewHolder();
private List<CategoriesClass> categories = new ArrayList<CategoriesClass>();
public static final int ACTIVITY_CREATE = 10;
public static List<Integer> prefferedCategories = new ArrayList<Integer>();
private int i = 0;
// Keep all Images in array
// public Integer[] mThumbIds = { R.drawable.pic_1, R.drawable.pic_2,

this.mContext = c;
this.categories = categories;
this.prefferedCategories = prefferedCategories;
mInflater = (LayoutInflater) mContext
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
thumbnailsselection = new ArrayList<String>();
}
class ViewHolder {

TextView tv_categoryname;
// LinearLayout ll_category_selection;

}
[user=439709]@override[/user]

holder.cb_check_category.setBackgroundColor(Color.TRANSPARENT);

.toUpperCase());
holder.cb_check_category

} else {

prefferedCategories.remove(categories.get(position).categoryid);
}
}
});
ImageLoader imageload = new ImageLoader(mContext);
imageload.DisplayImage(
categories.get(position).defaultCategoryImage.toString(),
holder.imageview);
holder.imageview.setScaleType(ImageView.ScaleType.CENTER_CROP);
return convertView;
}
[user=439709]@override[/user]
public int getCount() {
// TODO Auto-generated method stub
return categories.size();
}
[user=439709]@override[/user]
public Object getItem(int position) {
// TODO Auto-generated method stub
return position;
}
[user=439709]@override[/user]
public long getItemId(int position) {

return position;
}
}
Can someone maybe build an App with this Code? I ask because I have no clue about that, but I think the sourcecode is good and many guys would be happy. Maybe some Guy has the time to do it? (It is maybe a cool App for the Playstore too).
Thank you for the attention.

Click to expand...
Click to collapse
Me too .Looking for the same thing for a long time.
But could not find any.:crying:
Just wishing some guy to build an apk that would run on all phones like some other games.
Keep searching and kindly share if you find any.:good:
Thanks
Thank you man for posting this i think a lot of us wish to get this app on cyanogenmod for example i hope there's a hero dev. Can do this for us

I'm new to android,stuck in this part of my code.
I do hope, someone would help me with it.
As ,I've stuck for quite a while and have to complete within 2 days,
If I would like to filter in spinner based on the dates, how should I do it? For example,
I've a list of events, and in my spinner
when I select "Today", it will show out the list for today.
I've tried out the coding, however, I met some error. The part in BOLD, ** is having error.
I would like to get the XML data from here:

Hi,
I am developing an android app in which i am using csv file and displaying column contents as listview its displaying as [a,b,c,d] in single row how to display them in individual row in listview.Please any one help me how to achive this.
This is my csv file reading code using hashcode.
Code:
public static Map<String,ArrayList<String>> parseCsv(InputStreamReader reader, String separator, boolean hasHeader) throws IOException {
Map<String,ArrayList<String> > values = new LinkedHashMap<String,ArrayList<String>>();
List<String> columnNames = new LinkedList<String>();
BufferedReader br = null;
br = new BufferedReader(reader);
String line;
int numLines = 0;
while ((line = br.readLine()) != null) {
//if (StringUtils.isNotBlank(line)) {
//if (!line.startsWith("#")) {
String[] tokens = line.split(separator);
if (tokens != null) {
for (int i = 0; i < tokens.length; ++i) {
if (numLines == 0) {
columnNames.add(hasHeader ? tokens[i] : ("row_"+i));
} else {
ArrayList<String> column = values.get(columnNames.get(i));
if (column == null) {
column = new ArrayList<String>();
}
column.add(tokens[i]);
values.put(columnNames.get(i), column);
}
}
}
++numLines;
}
// }//
// }//
return values;
listview code is:
Code:
oslist.add(values);
ListView list = (ListView) findViewById(R.id.studentnames);
String name="name";
// Add it listview
ListAdapter adapter = new SimpleAdapter(this,
oslist, R.layout.student_list, new String[] { name }, new int[] { R.id.name});
list.setAdapter(adapter);
So i found this perfect code to be able to select zip from sd, but the list looks so basic and I would like to add icons (like one common icon for all dirs), however it seems too hard to do on my own, here is the code:
Code:
private void loadFileList(File path) {
this.currentPath = path;
List<String> r = new ArrayList<String>();
if (path.exists()) {
if (path.getParentFile() != null) r.add(PARENT_DIR);
FilenameFilter filter = new FilenameFilter() {
@SuppressLint("DefaultLocale")
public boolean accept(File dir, String filename) {
File sel = new File(dir, filename);
if (!sel.canRead()) return false;
if (selectDirectoryOption) return sel.isDirectory();
else {
boolean endsWith = fileEndsWith != null ? filename.toLowerCase().endsWith(fileEndsWith) : true;
return endsWith || sel.isDirectory();
}
}
};
String[] fileList1 = path.list(filter);
for (String file : fileList1) {
r.add(file);
}
}
fileList = (String[]) r.toArray(new String[]{});
}
