private void animationScale(View v){
ObjectAnimator animatorX = ObjectAnimator.ofFloat(v,"ScaleX", 1.0F, 0.8F, 1.2F, 1.0F);
ObjectAnimator animatorY = ObjectAnimator.ofFloat(v,"ScaleY", 1.0F, 0.8F, 1.2F, 1.0F);
AnimatorSet animatorSet = new AnimatorSet();
animatorSet.playTogether(animatorX, animatorY);
animatorSet.setDuration(80);
animatorSet.start();
}
class tabOntouchListener implements View.OnTouchListener{
@Override
public boolean onTouch(View v, MotionEvent event) {
switch (event.getAction()){
case MotionEvent.ACTION_UP:
animationScale(v);
break;
}
return false;
}
}
mTabHost.getTabWidget().getChildAt(0).setOnTouchListener(new tabOntouchListener());
這樣的效果只在手機“開發者選項”中設置爲開啓動畫時纔有效果；如果希望在關閉動畫的時候也希望有效果我是下面這樣寫的
static float scalex[]={1.0F, 0.8F, 1.2F, 1.0F};
private static void animationScale(final View v,final int time,final int index){
final AnimationSet animationSet = new AnimationSet(true);
ScaleAnimation scaleAnimation = new ScaleAnimation(scalex[index],scalex[index+1],scalex[index],scalex[index+1], Animation.RELATIVE_TO_SELF,0.5f,Animation.RELATIVE_TO_SELF,0.5f);
//3秒完成動畫
scaleAnimation.setDuration(time);
animationSet.addAnimation(scaleAnimation);
//啓動動畫
v.startAnimation(animationSet);
animationSet.setAnimationListener(new Animation.AnimationListener() {
@Override
public void onAnimationStart(Animation animation) {
}
@Override
public void onAnimationEnd(Animation animation) {
if(index < scalex.length-2){
animationScale(v,time,index+1);
}
}
@Override
public void onAnimationRepeat(Animation animation) {
}
});
}
