问题描述

我希望找到所有有标签气球，例如，然后使用 setVisibility 隐藏它们以指定活动GONE意见。

I am looking to find all the views in a specified activity that have the tag "balloon" for example then hide them using setVisibility to GONE.

有谁知道如何检索与给定的标签视图列表？

Does anyone know how to retrieve a list of views with a given tag?

推荐答案

在这里你去：

private static ArrayList<View> getViewsByTag(ViewGroup root, String tag){
    ArrayList<View> views = new ArrayList<View>();
    final int childCount = root.getChildCount();
    for (int i = 0; i < childCount; i++) {
        final View child = root.getChildAt(i);
        if (child instanceof ViewGroup) {
            views.addAll(getViewsByTag((ViewGroup) child, tag));
        }

        final Object tagObj = child.getTag();
        if (tagObj != null && tagObj.equals(tag)) {
            views.add(child);
        }

    }
    return views;
}
