Question

我一直以下面和roid光为榜样。

I am able to trigger an action when a child is clicked however I cannot seem to figure out how to: 1. Customize the label of each child. 2. Change how each child looks. (for example I would like each child to display the phone number and then two graphical buttons on the right. Each button would have a custom action tied to it.)

任何守则或联系都将受到高度赞赏。

一种可能的解决办法是:使用 SimpleCursorTreeAdapter.ViewBinder ,使用

我肯定不会这样做,因为我没有尝试这样做,但似乎也一样。我试图解决同样的问题,这样,如果我不工作,我就试图在这里发言。

你可以在你简单的CursorTreeAdapter中推翻“儿童意见”。这是我如何做的:

      class MyAdapter extends SimpleCursorTreeAdapter {

        @Override
    protected void bindChildView(View view, Context context, Cursor cursor, boolean isLastChild) {
        // TODO Auto-generated method stub
        super.bindChildView(view, context, cursor, isLastChild);

        String title = cursor.getString(cursor.getColumnIndex(Alert.COL_DAY));              
        ((TextView)view.findViewById(R.id.child_day)).setText(title);           
    }

        public MyAdapter(Context context, Cursor cursor,
                int groupLayout, String[] groupFrom, int[] groupTo,
                int childLayout, String[] childFrom, int[] childTo) {

          super(context, cursor, groupLayout, groupFrom, groupTo, childLayout, childFrom, childTo);
        }

        protected Cursor getChildrenCursor(Cursor groupCursor) {
          int idColumn = groupCursor.getColumnIndex(Pill.COL_ID);
          return Alert.list(db, groupCursor.getInt(idColumn), null, Alert.COL_DAY);
        }

  }

然而,在创建时,你必须提供子女退学和子女退学,以适应,从而在具有约束力的意见中加以利用。

您不妨看 CursorTreeAdapter ,并对ChildView方法具有约束力。
