当手机静音时，使Vibrator.vibrate不执行任何操作 - Android

Question

如果手机响铃状态为mute，是否有一种方法可以使振动无法通过Vibrator.vibrate方法工作，以免手动检查它？

Answer 1

检查状态和做

AudioManager am = (AudioManager) this.getSystemService(Context.AUDIO_SERVICE); 
    if (am.getRingerMode() == AudioManager.RINGER_MODE_SILENT) { 
     Toast.makeText(this, "cannot vibrate already muted", Toast.LENGTH_SHORT).show(); 
    } else { 
     Vibrator vibrator = (Vibrator) this.getSystemService(Context.VIBRATOR_SERVICE); 
     vibrator.vibrate(2000); 
     Toast.makeText(this, "I'm running", Toast.LENGTH_SHORT).show(); 
    }
