在 Android 中以编程方式分配视图 ID [英] Assign a view ID programmatically in Android

问题描述

我正在尝试以编程方式与几个孩子一起创建一个 RelativeLayout.要使 RelativeLayout.RIGHT_OF 之类的规则起作用，子视图必须具有正确的 ID.

I'm trying to create a RelativeLayout with several children programmatically. To make the rules like RelativeLayout.RIGHT_OF work, the child views must have proper IDs.

但是，当我尝试分配 ID 时，Android Studio 将其标记为错误:

However, when I try to assign an ID, Android Studio flags it as an error:

view.setId(123);

ERROR: Expected resource of type id

推荐答案

找到了:

view.setId(View.generateViewId());
