如何在代碼中從一個LinearLayout復制參數並將其設置為另一個LinearLayout？ 我嘗試過像

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);

但它完全忽略了。 如何解決這個問題呢 ？

如果llRight和llLeft的父llLeft是RelativeLayout ，則應使用：

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);
