如何在代码中从一个LinearLayout复制参数并将其设置为另一个LinearLayout？

Question

How to copy params from one LinearLayout and set to another LinearLayout in code ? I have tried like

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);

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

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);
