推荐答案

您可以做到这一点就像这样

You can do it just like that

ViewGroup parent;
    int position;

    for(int i = 0; i < parent.getChildCount(); ++i) {
        int currentViewId = parent.getChildAt(i).getId();

        if(currentViewId == wantendViewId) {
            position = i;
        }
    }

这是（在我看来）最简单的方法

That's (in my opinion) the simplest way
