How do I mute all sounds of my application?

问题

I'm creating a quiz app just for learning, and I've got a problem.

In my mainactivity I have a media player. It plays music even going through other activities, and I have a mute button to stop the music. I also have a sound effect when I successfully hit the right answer (on a question which is in other activity). But I don't know how to mute this SFX along with the background music when I press the mute button. Any hints? ;)

If it has a way to mute my entire application will be so good. I found some ways to mute, but this way will mute the entire system. And it's

AudioManager audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
audioManager.setStreamMute(AudioManager.STREAM_MUSIC, false);

You can just use AudioManager.setStreamMute(). Feel free to use the code below.

    //mute audio
AudioManager amanager=(AudioManager)getSystemService(Context.AUDIO_SERVICE);
             amanager.setStreamMute(AudioManager.STREAM_NOTIFICATION, true);
         


//unmute audio
AudioManager amanager=(AudioManager)getSystemService(Context.AUDIO_SERVICE);
             amanager.setStreamMute(AudioManager.STREAM_NOTIFICATION, false);

If you want to mute only the running apps sound, then you better do this:

MediaPlayer mp = MediaPlayer.create(context, R.raw.sound_file_1); //Use your mediaplayer instance instead of this. Also maintain a single instance of mediaplayer for the entire app.
    mp.start();

For Mute

mp.setvolume(0,0);

& Unmute or full volume

mp.setvolume(0,1);

Try this. It may be of help to you.

AudioManager manager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);    
manager.setStreamVolume(AudioManager.STREAM_ALARM, 0, AudioManager.FLAG_REMOVE_SOUND_AND_VIBRATE);
