Hi All! I'm trying to create an always-op-top button/clickable-image which stays on top of all the windows all the time. The proof of concept is here http://www.appbrain.com/app/smart-taskbar-(sidebar)/com.smart.taskbar and here http://forum.xda-developers.com/showthread.php?t=865525 I'm following this example code http://android.git.kernel.org/?p=pl...6429aaa5ccf6ecf311dfb3af0f3ccbf5f8d29;hb=HEAD
I have been successful and have a running service now. The service displays some text on top left corner of screen all the time while user can freely interact with rest of apps in normal manner. What I'm doing is subclass ViewGroup and add it to root window manager with flag TYPE_SYSTEM_OVERLAY. Now I want to add a button/clickable-image in place of this text which can receive touch events on itself. I tried overriding "onTouchEvent" for the whole ViewGroup but it does not receive any event. How can I receive events only on certain parts of my always-on-top view group? Kindly suggest.

How did you solve that problem???
I modified this:
http://www.pocketmagic.net/android-overlay-cursor/
Unfortunately,I didn't made it clickable(movable around the screen),so all dimensions and positions are hardcoded.
I can modify it for myself anytime and noone use my app.

Hey Android experts,
this may be a n00b like question but I'm a beginner to android and i'm struggling with displaying images in a gridview. All i need to do is display the images i have located in res/drawable when clicked on.
I currently have the following code in java
My GridView Class
package com.example.gridview;
import com.example.helloandroid.R;
import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.GridView;
public class HelloGridView extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
GridView gridview = (GridView) findViewById(R.id.gridview);
gridview.setAdapter(new ImageAdapter(this));
gridview.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
//Where I'm struggling, I just need to find a way to display img048 and img049 from mThumbsIds when clicked on
}
});
}
}
My ImageAdapter class
package com.example.gridview;
import com.example.helloandroid.R;
import android.content.Context;
import android.view.View;
import android.view.ViewGroup;
import android.widget.BaseAdapter;
import android.widget.GridView;
import android.widget.ImageView;
public class ImageAdapter extends BaseAdapter {
private Context mContext;
public ImageAdapter(Context c) {
mContext = c;
}
public int getCount() {
return mThumbIds.length;
}
public Object getItem(int position) {
return null;
}
public long getItemId(int position) {
return 0;
}
// create a new ImageView for each item referenced by the Adapter
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView;
if (convertView == null) { // if it's not recycled, initialize some attributes
imageView = new ImageView(mContext);
imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setPadding(8, 8, 8, 8);
} else {
imageView = (ImageView) convertView;
}
imageView.setImageResource(mThumbIds[position]);
return imageView;
}
// references to our images
private Integer[] mThumbIds = {
R.drawable.img048, R.drawable.img049
};
}
Thank you SO MUCH everybody!
Hello XDA,
So I've not found anyone properly discussing this. If they do, please link me to the page and don't flame
I've been making an app for my school and so far, I've been doing alright. But now I have run into a problem which seems to be very hard to solve for me alone.
Namely, I have an EditText and a Button in one Activity and a WebView as a different Activity.
I'm trying to get the EditText String into the WebView URL (String being variable, Button initiating the WebView), but get a lot of errors, some not even related to that.
I would really appreciate it if someone could have a look at the code and help me with this
MyWebView.java:
Code:
package bas.sie.Antonius;
import android.app.Activity;
import android.os.Bundle;
import android.widget.EditText;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MyWebView extends Activity {
WebView mWebView;
EditText mEtxtStudentNum;
static String StudentNumFromHome = bas.sie.Antonius.Home.StudentNum;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient());
mWebView.loadUrl("http://carmelcollegegouda.nl/site_ant/roosters/standaardroosters/Lee1_" + StudentNumFromHome + ".htm");
}
}
Home.java (Homescreen):
Code:
package bas.sie.Antonius;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class Home extends Activity {
Button mBtnStSchedule;
static EditText mEtxtStudentNum;
static final String StudentNum = mEtxtStudentNum.getText().toString();
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button next = (Button) findViewById(R.id.BtnStSchedule);
next.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent myIntent = new Intent(view.getContext(), MyWebView.class);
startActivityForResult(myIntent, 0);
}
});
// TODO Auto-generated method stub
}
}
AntoniusActivity.java (Main):
Code:
package bas.sie.Antonius;
import android.app.TabActivity;
import android.content.Intent;
import android.content.res.Resources;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.TabHost;
public class AntoniusActivity extends TabActivity {
WebView mWebView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources res = getResources(); // Resource object to get Drawables
TabHost tabHost = getTabHost(); // The activity TabHost
TabHost.TabSpec spec; // Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, Home.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("home").setIndicator("Home",
res.getDrawable(R.drawable.ic_tab_home))
.setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, External.class);
spec = tabHost.newTabSpec("external").setIndicator("External",
res.getDrawable(R.drawable.ic_tab_external))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, Contact.class);
spec = tabHost.newTabSpec("contact").setIndicator("Contact",
res.getDrawable(R.drawable.ic_tab_contact))
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(2);
}
private class HelloWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
In AntoniusActivity, the private class HelloWebViewClient is underlined with yellow (never used), specifically the bit "HelloWebViewClient".
It's also throwing FC's at startup, and errors in LogCat, but I'll post those later on, as it's 10.30 PM here, and school goes on
Thanks in advance,

How you doin'? Greetings from my GT-I9000!
I have trouble creating a service for a mediaplayer. I would like to have startforeground instead of this as well. But I have no proof of my service running. So I dont know if my code actually works. Can someone help me?
If someone is able to help me completely setting up my service, I may pay €5-10. I received €50 from the company to set up a developer account. So I have €25 left.
I am creating a streaming app for a radio station to listen to the internet stream.
Code:
package jonashendrickx.radioplayer.rgrfm;
import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;
import android.util.Log;

public class RadioService extends Service {
private final IBinder mBinder = new RadioBinder();
@Override
public void onCreate() {
Toast.makeText(this, "Let's Go", Toast.LENGTH_SHORT).show();
}
@Override
public IBinder onBind(Intent arg0) {
Log.e("LocalService", "Launched");
return mBinder;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.i("LocalService", "Received start id " + startId + ": " + intent);
return START_STICKY;
}
public class RadioBinder extends Binder {
RadioService getService() {
return RadioService.this;
}
}
}

public class MainActivity extends Activity {

@Override
public void onServiceConnected(ComponentName className, IBinder service) {
mRadioService = ((RadioService.RadioBinder)service).getService();
}
@Override

mIsBound = true;
Log.e("", "service started");

this is alert dialog activity.

}*/
}
this is working fine.Anyway if added the below two line end Oncreate method of the main activity it doesn't wait untill the alert dialog finishes.it goes to contact activity .So i don't have chance to select option from alert dialog.how to avoid this situation?
