Class Overview

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. TextViews bind the values to their text property (see setText(CharSequence)). ImageViews bind the values to their image's Uri property (see setImageURI(android.net.Uri)).

Protected Methods

protected void bindChildView (View view, Context context, Cursor cursor, boolean isLastChild)

Bind an existing view to the child data pointed to by cursor

Parameters

view	Existing view, returned earlier by newChildView
context	Interface to application's global information
cursor	The cursor from which to get the data. The cursor is already moved to the correct position.
isLastChild	Whether the child is the last child within its group.

protected void bindGroupView (View view, Context context, Cursor cursor, boolean isExpanded)

Bind an existing view to the group data pointed to by cursor.

Parameters

view	Existing view, returned earlier by newGroupView.
context	Interface to application's global information
cursor	The cursor from which to get the data. The cursor is already moved to the correct position.

protected void setViewImage (ImageView v, String value)

Called by bindView() to set the image for an ImageView. By default, the value will be treated as a Uri. Intended to be overridden by Adapters that need to filter strings retrieved from the database.
