我想显示基于用户点击按钮的布局，当用户点击按钮时我保持在位置我只需要在特定位置可见，但我的问题是当开始可见或去基于视图的用户时点击按钮，布局对于所有位置都是可见的，如何显示linerlauout仅对用户克隆位置是可见的。

在ListViewAdapter中，您需要删除构建列表的项目列表View
所以你需要从mOptinItems，dateArray，myImageList中删除项目
然后设置notifyDataSetChanged
final ArrayAdapter adapter = ((ArrayAdapter)getListAdapter());
runOnUiThread(new Runnable() {
public void run() {
adapter.notifyDataSetChanged();
}
});
