The form of mobile phone screen jitter

Yesterday QQ the group was asked to category like QQ Chat window is how to achieve the jitter effect. Here, I just realized what to put on the code:

<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[] {3, +, (+), +); T Ranslateanimation translateanimation = new Translateanimation (150,200, n); Translateanimation.setduration (2000) ; Interpolator interpolator = new Cycleinterpolator (5); Translateanimation.setinterpolator (Interpolator); Decorview.startanimation (translateanimation);</span>

Yes, it's that simple.
