手机屏幕窗体抖动的实现

昨天在qq群上有人问到类似QQ的聊天窗体抖动效果是怎么实现的，在这里我就简单的实现了一下，贴上代码：

<span style="font-family:Courier New;">                final View decorView = ((ViewGroup) findViewById(android.R.id.content)).getChildAt(0);

		Vibrator vibrator = (Vibrator) getSystemService(VIBRATOR_SERVICE);
		vibrator.vibrate(new long[] { 200, 100, 200, 100 }, 3);

		TranslateAnimation translateAnimation = new TranslateAnimation(50, 150,200, 50);
		translateAnimation.setDuration(2000);
		Interpolator interpolator = new CycleInterpolator(5);
		translateAnimation.setInterpolator(interpolator);
		decorView.startAnimation(translateAnimation);</span>
