Determine whether the phone is in silent, vibration, normal mode

It can be seen from AudioManager that there are three states

    /**
     * Returns the current ringtone mode.
     *
     * @return The current ringtone mode, one of {@link #RINGER_MODE_NORMAL},
     *         {@link #RINGER_MODE_SILENT}, or {@link #RINGER_MODE_VIBRATE}.
     * @see #setRingerMode(int)

    public int getRingerMode() {
        final IAudioService service = getService();
        try {
            return service.getRingerModeExternal();
        } catch (RemoteException e) {
            throw e.rethrowFromSystemServer();
        }
    }

 

If you want to know the current ringtone status of the mobile phone, you can directly getRingerMode () to get:

  import android.media.AudioManager;

            AudioManager audioManager = (AudioManager) mContext.getSystemService(Context.AUDIO_SERVICE);                     
            final int ringerMode = am.getRingerMode();
            switch (ringerMode) {
                case AudioManager.RINGER_MODE_NORMAL:
                    //normal
                    break;
                case AudioManager.RINGER_MODE_VIBRATE:
                    //vibrate
                    break;
                case AudioManager.RINGER_MODE_SILENT:
                    //silent
                    break;
            }

 

When the user sets the scene mode, the system will broadcast a RING_MODE_CHANGE_ACTION message, we can also define a broadcast receiver, listen to this message, and then determine the current scene mode through the interface provided by AudioManager to make specific processing.

private BroadcastReceiver mReceiver = new BroadcastReceiver() {
	@Override
	public void onReceive(Context context, Intent intent) {
		if (intent.getAction().equals(AudioManager.RING_MODE_CHANGE_ACTION)) {
			AudioManager audioManager = (AudioManager)getSystemService(Context.AUDIO_SERVICE);
			final int ringerMode = am.getRingerMode();
			switch (ringerMode) {
				case AudioManager.RINGER_MODE_NORMAL:
					//normal
					break;
				case AudioManager.RINGER_MODE_VIBRATE:
					//vibrate
					break;
				case AudioManager.RINGER_MODE_SILENT:
					//silent
					break;
			}
		}
	}
}
