问题描述
我想使我的alert dialog box像这样.这是一个弹出窗口，您必须在其中选择并选择类别.单击任何listview项时就会出现.
I want to make my alert dialog box something like this.This is a popup window where you have to choose and select the category.Its coming when I click any listview item..
但是我最终做了这样的事情.因为我是新手，所以对设计不太了解.请为此提供帮助.
But I ended up make it something like this.as i am a newbie so don't know much about designing.kindly help me in this.

使用以下内容替换您的布局xml文件:
Replace your layout xml file with this:
