Question

I would like to add a LayoutParam (FLAG_TURN_SCREEN_ON) to a view that I have defined via XML.

EDIT: This is a window flag WindowManager.LayoutParams.

Would I do this in the xml as well, or is there a way to add the params to the view before i call:

setContentView(R.layout.my_view);

UPDATE: Apparently this was not the easiest way to go about waking up the phone. Check the accepted answer about using the PowerManger to do it.

Answer 1

Try using

getWindow().addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);

before you call your setContentView method.

Alternatively, try using the PowerManager class. Make sure you request the proper WAKE_LOCK permission in your manifest:

<uses-permission android:name="android.permission.WAKE_LOCK" />

Here is an example from the documentation:

PowerManager pm = (PowerManager) getSystemService(Context.POWER_SERVICE);
PowerManager.WakeLock wl = pm.newWakeLock(PowerManager.SCREEN_DIM_WAKE_LOCK, "My Tag");
wl.acquire();
//   ..screen will stay on during this section..
wl.release();
