删除里面的LinearLayout的所有项目

问题描述

我创建的LinearLayout的refes到XML项目。这里面的LinearLayout我把一些TextView的动态，所以没有从XML服用。现在，我需要从LinearLayout中删除这些textviews。我想这样的：

I create a linearlayout that refes to an xml item. Inside this linearlayout i put some textview dynamically, so without taking them from the xml. Now i need to remove these textviews from the linearlayout. I tried this:

if(((LinearLayout) linearLayout.getParent()).getChildCount() > 0)
    ((LinearLayout) linearLayout.getParent()).removeAllViews();

，但它不工作。我能怎么做？谢谢，马蒂亚

but it doesn't work.How can i do?Thanks, Mattia

推荐答案

为什么要这么写 linearLayout.getParent（）你应该做的这一切直接的LinearLayout

Why you wrote linearLayout.getParent() you should do all this directly on LinearLayout

if(((LinearLayout) linearLayout).getChildCount() > 0)
    ((LinearLayout) linearLayout).removeAllViews();
