Question

I’m trying custom the theme of Media Volume Controller (I don’t know what it’s called, just try to name it). It’s something like a Toast with "Media Volume" title which appears when we press volume buttons (+ and -) in games. But I don’t know which View it’s, or it’s a Toast, a Dialog. So far as I try, I could not find anything which refers it. Only Activity.setVolumeControlStream(AudioManager.STREAM_MUSIC)
to enable it in your Activity, and nothing more. If someone know how to custom it, or just it’s name, please help me!
Thanks.

Sorry for my misunderstanding of your question.

I think the way you can customize “Media Volume Controller” is control volume yourself and show your customize view(or Toast). Because the “Media Volume” Toast(It is a Toast, see the source code of VolumePanel.onShowVolumeChanged ) is created and shown by android system which you cannot customize.

Here is the sample code which might solve your problem:

public boolean onKeyDown(int keyCode, KeyEvent event) {
    AudioManager am = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE);
    if (keyCode == KeyEvent.KEYCODE_VOLUME_UP) {
        // Or use adjustStreamVolume method.
        am.adjustVolume(AudioManager.ADJUST_RAISE, AudioManager.FLAG_PLAY_SOUND);
        Toast.makeText(this, "Volume up", Toast.LENGTH_SHORT).show();
        return false;
    } else if (keyCode == KeyEvent.KEYCODE_VOLUME_DOWN) {
        // Or use adjustStreamVolume method.
        am.adjustVolume(AudioManager.ADJUST_LOWER, AudioManager.FLAG_PLAY_SOUND);
        Toast.makeText(this, "Volume down", Toast.LENGTH_SHORT).show();
        return false;
    }
    return super.onKeyDown(keyCode, event);
}
