隐形匆匆不工作在Android的动画完成后，

问题描述

我用这个code当我点击一个imagebox，另一个对象运行的动画，并通过visibility.GONE dissaper本身。但它不工作！这里是我的code：

i use this code to when i click on a imagebox, run an animation on another object and dissaper itself via visibility.GONE. but it doesnt work!! here is my code:

againbtn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            //answer button on animation
            Animation anim2 = AnimationUtils.loadAnimation(MainActivity.this, R.anim.askbtnonanim);
            anim2.setFillAfter(true);
            askbtn.startAnimation(anim2);

            //gone myselft (againbtn)
            againbtn.setVisibility(View.GONE);
        }
    });

如果从这个code删除动​​画3线，一切都OK和工作，但现在没有。但为什么？它涉及到anim2.setFillAfter（真）; ???我把这个，因为我的动画运行一次，不重！请大家帮我

if a delete 3 animation line from this code, everything is OK and works, but now it doesn't. but why? it's related to anim2.setFillAfter(true); ??? i put this because my animation run one time and dont reset! please help me

推荐答案

您应该实现动画监听器和onAnimationEnd（），你应该执行你的任务...下面code，希望会帮助你...

You should implement Animation Listener and in onAnimationEnd() you should perform your task... hope below code will help you...

anim2.setAnimationListener(new Animation.AnimationListener(){
    @Override
    public void onAnimationStart(Animation arg0) {
    }           

    @Override
    public void onAnimationRepeat(Animation arg0) {
    }           

    @Override
    public void onAnimationEnd(Animation arg0) {
        againbtn.setVisibility(View.GONE);  //set your button visibility here
    }


});
