推荐答案

添加

android:descendantFocusability="blocksDescendants"

在自定义GridView项的rootview中

in the rootview of your custom GridView item

   <?xml version="1.0" encoding="utf-8"?>
     <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            ...
            android:descendantFocusability="blocksDescendants"
            >
            ...
             <Button
             ...
             /> 
            ...      
   </LinearLayout>
