安卓java+弹出通知,其他活动之上的Android消息通知对话框

How do I get an Android message notification dialog on top of other activities?

I am searching for a solution to this problem and still not yet got the solution. Right now, I am developing a social networking app in which I need to show a notification message dialog whenever the user gets some message from another and to achieve that I have used the broadcast receiver and it is working fine.

The problem is how to show the notification dialog on top of another application.

Yes, it is possible. The Main.xml layout has one edit text and button. The Messagebox layout has one button. Here you can change message layout to whatever you want.

File MyScheduledReceiver.java:

public class MyScheduledReceiver extends BroadcastReceiver {

@Override

public void onReceive(Context context, Intent intent) {

// TODO Auto-generated method stub

Intent scheduledIntent = new Intent(context, MessageBox.class);

scheduledIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

context.startActivity(scheduledIntent);

}

}

Main Activity:

public class AndroidMessageBoxActivity extends Activity implements OnClickListener

{

private EditText time;

private Button btn;

private AlarmManager alarm;

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

time = (EditText) findViewById(R.id.editText1);

btn = (Button) findViewById(R.id.button1);

alarm = (AlarmManager) getSystemService(Context.ALARM_SERVICE);

btn.setOnClickListener(this);

}

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

int x = Integer.parseInt(time.getText().toString());

Intent intent = new Intent(this, MyScheduledReceiver.class);

PendingIntent pendingIntent = PendingIntent.getBroadcast(

this.getApplicationContext(), 234324243, intent, 0);

alarm.set(AlarmManager.RTC_WAKEUP,

System.currentTimeMillis() + (x * 1000),

pendingIntent);

Toast.makeText(this,

"Alarm set in " + x + " seconds",

Toast.LENGTH_LONG).show();

}

}

MessageBox:

public class MessageBox extends Activity

{

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.messagebox);

Button btn = (Button) findViewById(R.id.Ok);

btn.setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

finish();

}

});

}

}

And add these two lines in the Android manifest XML file:

Filestyle.xml:

true

@null

@android:color/transparent

true

false
