android 震动效果实现，从Settings里面读值

震动效果实现如下：

 

if(Settings.System.getInt(getContentResolver(), Settings.System.LOCKSCREEN_SOUNDS_ENABLED, 1) != 0) { Vibrator vibrator = (Vibrator) getSystemService("vibrator"); vibrator.vibrate(50); }

 

飞行模式判定：

/** * judge current airplane mode is set on * * @return */ private boolean isAirplanemodeOn() { return Settings.System.getInt(getContentResolver(), Settings.System.AIRPLANE_MODE_ON, 0) != 0; }
