Android - checkable buttons on options menu

Question

Can anyone point in the direction of any tutorials that show how to create an options menu with clicakble checks like in the picture below:

I have tried as follows:

/** Menu creation and setup **/

/* Creates the menu items */ public boolean onCreateOptionsMenu(Menu menu) { boolean result = super.onCreateOptionsMenu(menu);

   menu.add(0, 1, 0, "Speaker").setCheckable(true);
   menu.add(0, 2, 0, "Mute").setCheckable(true);
   return result;

}

/* Handles item selections */ public boolean onOptionsItemSelected(MenuItem item) { switch (item.getItemId()) { case 1: if(audioManager.isSpeakerphoneOn()==false){ audioManager.setSpeakerphoneOn(true); audioManager.setRouting(AudioManager.MODE_IN_CALL, AudioManager.ROUTE_SPEAKER, AudioManager.ROUTE_ALL); }else{ audioManager.setSpeakerphoneOn(false); audioManager.setRouting(AudioManager.MODE_IN_CALL, AudioManager.ROUTE_EARPIECE, AudioManager.ROUTE_ALL); } return true; case 2: if(audioManager.isMicrophoneMute()) audioManager.setMicrophoneMute(false); else audioManager.setMicrophoneMute(true); return true; } return false; }

But this doesn't work it only gives me text on the buttons on the options menu

EDIT: I have added the following onPrepareOptionsMenu method:

public boolean onPrepareOptionsMenu(Menu menu){
boolean result = super.onPrepareOptionsMenu(menu);

if(audioManager.isSpeakerphoneOn())
 menu.findItem(1).setChecked(true);
else
 menu.findItem(1).setChecked(false);

if(audioManager.isMicrophoneMute())
 menu.findItem(2).setChecked(true);
else
 menu.findItem(2).setChecked(false);


return result;

}

However I get the same outcome just text and no check light as in the picture above

If you want to change dynamically the state of your Option Menu, you need to use onPrepareMenu(). In this method, you can do dynamic checks and update anything you want. Good luck!!

After some digging, this look like a custom view. I think your picture comes from this code.
