An easy adapter to map columns from a cursor to TextViews or ImageViews defined in an XML file. You can specify which columns you want, which views you want to display the columns, and the XML file that defines the appearance of these views. Separate XML files for child and groups are possible. Binding occurs in two phases. First, if aSimpleCursorTreeAdapter.ViewBinder is available,setViewValue(android.view.View, android.database.Cursor, int) is invoked. If the returned value is true, binding has occurred. If the returned value is false and the view to bind is a TextView,setViewText(TextView, String) is invoked. If the returned value is false and the view to bind is an ImageView, setViewImage(ImageView, String) is invoked. If no appropriate binding can be found, an IllegalStateException is thrown.
一个简单的适配器，从游标位置开始映射列到定义在一个XML文件中的TextView或ImageView你可以指定想要的列，想要显示列的视图，以及定义这些视图外观的XML文件。可能的话，为每个子项和组项指定单独的XML文件。将数据绑定到视图有两个阶段。首先，如果SimpleCursorTreeAdapter.ViewBinder是可用的，则调用setViewValue(android.view.View, android.database.Cursor, int)。如果返回值为true，则绑定成功。如果返回值为false，则调用setViewText(TextView, String)，以将视图绑定到一个TextView。如果返回值为false，则调用setViewImage(ImageView, String)，以将视图绑定到一个ImageView。如果找不到合适的绑定，则抛出一个IllegalStateException异常。

嵌套类

interfaceSimpleCursorTreeAdapter.ViewBinder

This class can be used by external clients of SimpleCursorTreeAdapter to bind values from the Cursor to views. 
这个类可以由SimpleCursorTreeAdapter的外部客户端使用，以便将从游标（Cursor)处的值绑定到视图。
