我设计了一个简单的布局，没有动画就完成了设计，但是现在我想在textview click事件时添加动画，但我不知道如何使用它。我的xml设计看起来不错还是不好？任何建议，将不胜感激。

您可以做两件事来添加动画，首先可以让android为您设置布局动画。这样，每次您更改布局中的某些内容（例如更改视图可见性或视图位置）时，android都会自动创建淡入淡出/过渡动画。要使用那套
android:animateLayoutChanges="true"
在布局的根节点上。
您的第二个选择是手动添加动画。为此，我建议您使用Android 3.0（Honeycomb）中引入的新动画API。我可以举几个例子：
这淡出了View：
View
view.animate().alpha(0.0f);
这使它淡入：
view.animate().alpha(1.0f);
这会将View其高度向下移动：
view.animate().translationY(view.getHeight());
将View其移动到其他位置后，它将返回到其初始位置：
view.animate().translationY(0);
您也可以使用setDuration()设置动画的持续时间。例如，这会View在2秒内逐渐消失：
setDuration()
view.animate().alpha(0.0f).setDuration(2000);
而且，您可以根据需要组合任意数量的动画，例如，它会淡出a View并在0.3秒内将其同时向下移动：
view.animate() .translationY(view.getHeight()) .alpha(0.0f) .setDuration(300);
您还可以为动画分配一个侦听器，并对各种事件做出反应。就像动画开始时，动画结束时或重复时一样。通过使用抽象类，AnimatorListenerAdapter您不必AnimatorListener一次实现所有的回调，而只需实现所需的那些。这使代码更具可读性。例如，以下代码淡出并View在0.3秒（300毫秒）的时间内将其向下移动高度，动画完成后，其可见性设置为View.GONE。
AnimatorListenerAdapter
AnimatorListener
View.GONE
view.animate() .translationY(view.getHeight()) .alpha(0.0f) .setDuration(300) .setListener(new AnimatorListenerAdapter() { @Override public void onAnimationEnd(Animator animation) { super.onAnimationEnd(animation); view.setVisibility(View.GONE); } });
