我可以设置＆QUOT;安卓la​​yout_below＆QUOT;在运行时，通过编程？ [英] Can I set "android:layout_below" at runtime, programmatically?

问题描述

在运行时创建一个相对的布局时，设置的 Android的等效是否有可能：layout_below 编程

Is it possible when creating a relative layout at runtime, to set the equivalent of android:layout_below programmatically?

推荐答案

是：

RelativeLayout.LayoutParams p = new RelativeLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT,
        ViewGroup.LayoutParams.WRAP_CONTENT);

p.addRule(RelativeLayout.BELOW, R.id.below_id);

viewToLayout.setLayoutParams(p);

首先code。通过指定的高度和宽度会创建一个新的布局PARAMS。该 addRule 方法添加XML属性格式安卓相当于：layout_below 。然后，你只需要调用查看＃setLayoutParams 在视图你想拥有这些PARAMS。

First the code creates a new layout params by specifying the height and width. The addRule method adds the equivalent of the xml propery android:layout_below. Then you just call View#setLayoutParams on the view you want to have those params.
