如何在代码中从一个 LinearLayout 复制参数并设置到另一个 LinearLayout ？我已经尝试过了

LinearLayout.LayoutParams paramsR=(LinearLayout.LayoutParams) llRight.getLayoutParams();
LinearLayout.LayoutParams paramsL=(LinearLayout.LayoutParams) llLeft.getLayoutParams();
paramsR.height=paramsL.height;
paramsR.width=paramsL.width;
llRight.setLayoutParams(paramsR);

，但它根本忽略了。如何解决这个问题？

LinearLayout.LayoutParams paramsL=(LinearLayout.LayoutParams) llLeft.getLayoutParams();
paramsR.height=paramsL.height;
paramsR.width=paramsL.width;
llRight.setLayoutParams(paramsR);

but it ignores at all. How to solve this problem ?

如果 llRight & 的父级llLeft 是 RelativeLayout 那么你应该使用：

RelativeLayout.LayoutParams paramsR=(RelativeLayout.LayoutParams) llRight.getLayoutParams();
RelativeLayout.LayoutParams paramsL=(RelativeLayout.LayoutParams) llLeft.getLayoutParams();
paramsR.height=paramsL.height;
paramsR.width=paramsL.width;
llRight.setLayoutParams(paramsR);

If the parent of llRight & llLeft is RelativeLayout then you should use:

RelativeLayout.LayoutParams paramsR=(RelativeLayout.LayoutParams) llRight.getLayoutParams();
RelativeLayout.LayoutParams paramsL=(RelativeLayout.LayoutParams) llLeft.getLayoutParams();
paramsR.height=paramsL.height;
paramsR.width=paramsL.width;
llRight.setLayoutParams(paramsR);
