与动画更新布局 [英] Update layout with the animation

问题描述

我有一个自定义视图从LinearLayout中继承。它包含一个按钮 和的EditText。 EditText上具有初始可见性设置为不见了。什么时候 按钮是pressed我想要的EditText出现动画效果。所以 我做了一个ScaleAnimation，当按钮被pressed我设置 的EditText＃setVisibility（可见），并启动动画。问题 是，它需要的空间为100％和动画内那些执行 边界。因此，当有更多的视图的下面放置他们正在向下移动 马上，但我希望他们能够慢慢移动，动画 进展。有没有办法做到这一点？

I have a custom View inherited from LinearLayout. It contains a Button and a EditText. EditText has initial visibility set to GONE. When Button is pressed I want EditText to appear with animation effect. So I've made an ScaleAnimation and when Button is pressed I set EditText#setVisibility(VISIBLE) and start the animation. The problem is that it takes 100% of space and animation is performed inside those bounds. So when there are more View's placed below they are moved down immediately, but I want them to move slowly as the animation progresses. Is there any way to do this?

推荐答案

我用通过覆盖动画applyTransformation方法，根据改造，解决我的问题，并调用视图的setLayoutParams。

I've used to solve my issue by overriding applyTransformation method of Animation and call View's setLayoutParams according to transformation.
