Question

我想通过翻译动画将图像按钮翻译到另一个位置（位置到另一个图像按钮）。我有两个职位。我所拥有的动画方法都使用相对位置变化，但我对绝对翻译感兴趣。在Android中有没有办法做到这一点？

 public void startAnimationFindChant(View view) {
            int[] locationSource = new int[2];
            int[] locationDestination = new int[2];
            view.geLocationOnScreen(locationSource);
             Log.d("locationSource",locationSource[0]+" "+locationSource[1]);
            ImageButton findachant1 = (ImageButton) findViewById(R.id.findachanticon1);

            findachant1.getLocationOnScreen(locationDestination);
            Log.d("locationDestination",locationDestination[0]+" "+locationDestination[1]);

            TranslateAnimation animation = new TranslateAnimation(
                    Animation.RELATIVE_TO_SELF, 0, Animation.RELATIVE_TO_SELF, 0,
                    Animation.ABSOLUTE, locationSource[1], Animation.ABSOLUTE,
                    locationDestination[1]);
            animation.setFillAfter(true);
            view.startAnimation(animation);
        }

public void doSlideUp(View view) {
    LinearLayout myView = (LinearLayout) findViewById(R.id.content_area);
    Animation slideUp = setLayoutAnim_slideup();
    myView.startAnimation(slideUp);

}

public void doSlideDown(View view) {
    RelativeLayout myView = (RelativeLayout) findViewById(R.id.content_area1);
    Animation slideDown = setLayoutAnim_slidedown();
    myView.startAnimation(slideDown);
}

public Animation setLayoutAnim_slidedown() {

    AnimationSet set = new AnimationSet(true);

    Animation animation = new TranslateAnimation(
            Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF,
            0.0f, Animation.RELATIVE_TO_SELF, -1.0f,
            Animation.RELATIVE_TO_SELF, 0.0f);
    animation.setDuration(2000);
    animation.setAnimationListener(new AnimationListener() {

        @Override
        public void onAnimationStart(Animation animation) {
        }

        @Override
        public void onAnimationRepeat(Animation animation) {
        }

        @Override
        public void onAnimationEnd(Animation animation) {

        }
    });
    set.addAnimation(animation);

    LayoutAnimationController controller = new LayoutAnimationController(
            set, 0.25f);

    return animation;
}

public Animation setLayoutAnim_slideup() {

    AnimationSet set = new AnimationSet(true);

    Animation animation = new TranslateAnimation(
            Animation.RELATIVE_TO_SELF, 0.0f, Animation.RELATIVE_TO_SELF,
            0.0f, Animation.RELATIVE_TO_SELF, 0.0f,
            Animation.RELATIVE_TO_SELF, -1.0f);
    animation.setDuration(2000);
    animation.setAnimationListener(new AnimationListener() {
        @Override
        public void onAnimationStart(Animation animation) {

        }

        @Override
        public void onAnimationRepeat(Animation animation) {

        }

        @Override
        public void onAnimationEnd(Animation animation) {




        }
    });
    set.addAnimation(animation);
    LayoutAnimationController controller = new LayoutAnimationController(
            set, 0.25f);
    return animation;
}

尝试此操作，并根据需要将动画x轴的值更改为y轴。

我使用ObjectAnimator -

在两个位置之间为TranslateAnimation创建了一个简单的类

private void translateAnimateView(View source, View target,
        AnimatorListener listener) {
    ObjectAnimator animator = ObjectAnimator.ofFloat(source,
            "translationY", 0, target.getTop() - source.getTop());
    animator.addListener(listener);

    animator.setDuration(1000);
    animator.start();
}

此方法接受三个参数，源视图，目标视图和侦听器（可以为null）。源将被动画化以达到目标视图。我刚刚添加了Y翻译，但你实际上也可以包含x翻译。

这样您就可以使用绝对位置进行翻译。你可以使用顶部坐标而不是视图。

动画不能正常工作？
