我有哪些类使用，设定时，的LayoutParams 我的的LinearLayout ？下面的两个不工作

Which class do I have to use, when setting the LayoutParams of my LinearLayout? The following two are not working:

如果我第一次拿到了参数，可以改变它们，并将它们设置回它的工作。所以，我想我得到ViewGroup.LayoutParams ...

if I get the params first, change them and set them back it's working. So I suppose the Params I get returned inherit from ViewGroup.LayoutParams...

你知道吗？ THX

推荐答案

使用母公司的的LayoutParams。所以，如果你的LinearLayout是RelativeLayout的一个孩子，那么你使用 linLayout.setLayoutParams（新android.widget.RelativeLayout.LayoutParams（50,50））;

Use the LayoutParams of the parent. So in case your LinearLayout is a child of RelativeLayout then you use linLayout.setLayoutParams(new android.widget.RelativeLayout.LayoutParams(50,50));
