Constructor Summary

ResourceCursorAdapter(android.content.Context context, int layout, android.database.Cursor c)
Deprecated. This option is discouraged, as it results in Cursor queries being performed on the application's UI thread and thus can cause poor responsiveness or even Application Not Responding errors. As an alternative, use LoaderManager with a CursorLoader.

ResourceCursorAdapter(android.content.Context context, int layout, android.database.Cursor c, boolean autoRequery)
Constructor with default behavior as per CursorAdapter.CursorAdapter(Context, Cursor, boolean); it is recommended you not use this, but instead ResourceCursorAdapter(Context, int, Cursor, int).

ResourceCursorAdapter(android.content.Context context, int layout, android.database.Cursor c, int flags)
Standard constructor.
