SimpleCursorTreeAdapter

public abstract class SimpleCursorTreeAdapter
extends ResourceCursorTreeAdapter

java.lang.Object
   ↳ android.widget.BaseExpandableListAdapter
     ↳ android.widget.CursorTreeAdapter
       ↳ android.widget.ResourceCursorTreeAdapter
         ↳ android.widget.SimpleCursorTreeAdapter

一个简单的适配器，可将游标中的列映射到XML文件中定义的TextView或ImageView。 您可以指定所需的列，要显示列的视图以及定义这些视图外观的XML文件。 为孩子和组分离XML文件是可能的。 绑定发生在两个阶段。 首先，如果有SimpleCursorTreeAdapter.ViewBinder可用，则调用setViewValue(android.view.View, android.database.Cursor, int) 。 如果返回值为true，则发生绑定。 如果返回值为false，并且要绑定的视图是TextView，则调用setViewText(TextView, String) 。 如果返回值为false，并且要绑定的视图是ImageView，则调用setViewImage(ImageView, String) 。 如果找不到合适的绑定， IllegalStateException抛出IllegalStateException 。
