Question

我将Bounce效果添加到Linear布局。这个线性布局包含2个EditTexts和一个按钮。但是当动画完成Edittexts和Button被禁用时。我无法使用它们。我可以启用Edittexts和Button。

Answer 1

尝试使用ObjectAnimator.onFloat代替。

 animloginButton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {


            if(lnrLoginView.getTag() instanceof Animator){
                ((Animator)lnrLoginView.getTag()).cancel();
            }
            ObjectAnimator translateY = ObjectAnimator
                    .ofFloat(target, "translationY", -transY)
                    .setDuration(1000)
            ;
            translateY.setStartDelay(10);
            translateY.setTarget(lnrLoginView);
            translateY.setInterpolator(new BounceInterpolator());
            translateY.start();
            animloginButton.setVisibility(View.INVISIBLE);
        }

        private int getDisplayHeight() {
            DisplayMetrics metrics = new DisplayMetrics();
            getWindowManager().getDefaultDisplay().getMetrics(metrics);
            return metrics.widthPixels;
        }
    });

Answer 2

使用动画侦听器在动画之前和之后制作视图。

translation.setAnimationListener(new AnimationListener() {

    @Override
    public void onAnimationStart(Animation animation) {
        //Disable the views.

    }

    @Override
    public void onAnimationRepeat(Animation animation) {
        // TODO Auto-generated method stub

    }

    @Override
    public void onAnimationEnd(Animation animation) {
        //Enable the views

    }
});

Android动画已禁用EditText
