import android.content.Context; import android.media.AudioManager; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.widget.SeekBar; public class mediavolumecontrol extends AppCompatActivity { AudioManager mAudio; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_mediavolumecontrol); mAudio = (AudioManager)getSystemService(Context.AUDIO_SERVICE); SeekBar alarm = (SeekBar)findViewById(R.id.alarm); SeekBar music = (SeekBar)findViewById(R.id.music); SeekBar ring = (SeekBar)findViewById(R.id.ring); SeekBar system = (SeekBar)findViewById(R.id.system); SeekBar voice = (SeekBar)findViewById(R.id.voice); initControls(alarm, AudioManager.STREAM_ALARM); initControls(music, AudioManager.STREAM_MUSIC); initControls(ring, AudioManager.STREAM_RING); initControls(system, AudioManager.STREAM_SYSTEM); initControls(voice, AudioManager.STREAM_VOICE_CALL); } private void initControls (SeekBar seek, final int stream) { seek.setMax(mAudio.getStreamMaxVolume(stream)); seek.setProgress(mAudio.getStreamVolume(stream)); seek.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() { public void onProgressChanged(SeekBar bar, int progress, boolean fromUser) { mAudio.setStreamVolume(stream, progress, AudioManager.FLAG_PLAY_SOUND); } public void onStartTrackingTouch(SeekBar bar) { } public void onStopTrackingTouch(SeekBar bar) { } }); } } |
- Now Open res -> layout -> activity_main.xml and then add following code :

Output:
Finally, run this project.
This is how android control volume programmatically in android looks like.
