Android的 - 如何编程方式指定重量为RelativeLayout的？ [英] Android - How do I specify weight programmatically for a RelativeLayout?

问题描述

我想这样做编程方式 -

I want to do something like this programmatically -

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

这并不让我做一个setWeight编程。但是，我看到RelativeLayout的有一个机器人：在XML layout_weight参数。我失去了一些东西？

It does not let me do a setWeight programmatically. However, I do see that RelativeLayout has an android:layout_weight parameter in XML. Am I missing something?

推荐答案

当您添加RelativeLayout的使用addView的LinearLayout中，你必须提供一个LinearLayout.LayoutParams，是这样的：

When you add the RelativeLayout to the LinearLayout using addView you have to provide a LinearLayout.LayoutParams, something like this :

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