编辑：

我认为我需要更清楚，我有一个屏幕上的 800dip 。而两个视点，第一个是的 200dip ，另一个就是 600dip 。所以第二个大小是由屏幕尺寸计算 - 第一尺寸，我不知道我是否通过动画更改第一个ImageView的大小为 600dip 当然第二ImageView的成为 200 自动的，可能发生的呢？

I think I need to make it more clear,I have a screen 800dip.and two view ,first is 200dip,another is 600dip.so the second size is calculate by screen size - first size,and I wonder if I change the first imageView size to 600dip by animation,and of course the second imageView become 200 automatic,could that happen?

推荐答案

您动漫变化查看hierarchi PARAMS，所以你应该申请新的布局PARAMS（LP）到ImageView的。

Your animation changes view hierarchi params so you should apply new layout params (lp) to ImageView.

创建一个将应用新的LP ImageView的每一帧设定不同的宽度/高度自定义动画。所以，你的图像视图会增加它的大小和移动其他意见。有很多例子来说明如何实现这一点。 看看这个。

Create custom animation which will apply new lp to ImageView setting different width/height on every frame. So your image view will increase it's size and move other views. There are a lot examples how to implement this. Take a look at this one.

    @Override
    protected void applyTransformation(float interpolatedTime, Transformation t) {
        android.view.ViewGroup.LayoutParams lp = mContent.getLayoutParams();
        lp.height = (int) (mStartHeight + mDeltaHeight * interpolatedTime);
        mContent.setLayoutParams(lp);
    }
