Hello,
I have tried to use SimpleCursorTreeAdapter class.
So, I have created my own that extends SimpleCursorTreeAdapter, like
below:
public MyListAdapter(MyModel model, Cursor cursor, Context context,
int groupLayout,
int childLayout, String[] groupFrom, int[] groupTo, String
[] childrenFrom,
int[] childrenTo) {
super(context, cursor, groupLayout, groupFrom, groupTo,
childLayout, childrenFrom,
childrenTo);
this.model = model;
}
protected Cursor getChildrenCursor(Cursor groupCursor) {
long group = groupCursor.getLong(groupCursor.getColumnIndex
(Constants.ID));
return this.model.getChildCursor(group);
}
As it appeared I receive Null Pointer Exception. Because in super
constructor we have call to templete method:
> protected Cursor getChildrenCursor(Cursor groupCursor)
method, that has reference to still uninitialized class field.
How do you propose to solve this issue?
