Android-based jitter Animation

Using an animation to make the control shake is actually to make the horizontal movement (which can be mixed with other types of rotation) of the animation loop playback, using the interpolator class.

The principle is very simple. I will not talk about it anymore,CodeAs follows:

Activity Code:

 
This. BTN. setonclicklistener (New onclicklistener () {@ overridepublic void onclick (view v) {textview yearandmouth = (textview) jgworklogdateandoperapanel. this. findviewbyid (R. id. year_mounth_text); animation cycleanim = animationutils. loadanimation (context, R. anim. img_anim); yearandmouth. startanimation (cycleanim );}});
 

Imag_anim.xml
