Android - 如何爲RelativeLayout以編程方式指定權重？

Question

我想這樣做編程 -

<LinearLayout> 
    <RelativeLayout1 weight = 1> 
    <RelativeLayout2 weight = 3> 
    <RelativeLayout3 weight = 1> 
<LinearLayout> 

它不會讓我做了setWeight編程。不過，我確實看到RelativeLayout在XML中有一個android：layout_weight參數。我錯過了什麼嗎？

當你使用addView添加的RelativeLayout到的LinearLayout，你必須提供一個LinearLayout.LayoutParams，是這樣的：

LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(width, height, weight); 
linearLayout.addView(relativeLayout, params);
