Android - 让孩子进入一个视图? [英] Android - get children inside a View?

问题描述

给定一个视图，如何在其中获取子视图?

Given a View how can I get the child views inside it?

所以我有一个自定义视图，调试器显示在 mChildren 下还有 7 个其他视图.我需要一种方法来访问这些视图，但似乎没有公共 API 可以做到这一点.

So I have a custom View and debugger shows that under mChildren there are 7 other views. I need a way to access these views but it doesn't seem like there is a public API to do this.

有什么建议吗?

我的自定义视图继承自 AdapterView

My custom view inherits from AdapterView

推荐答案

for(int index = 0; index < ((ViewGroup) viewGroup).getChildCount(); index++) {
    View nextChild = ((ViewGroup) viewGroup).getChildAt(index);
}

可以吗?
