从硬编码数组而不是DB创建游标 [英] Create a cursor from hardcoded array instead of DB

问题描述

我正在为一个正在写的小游戏应用程式建立拖曳清单。

I am trying to make a drag-and-drop list for a little game app I am writing.

清单中有6个项目。然而，我添加的库需要一个Cursor对象与数据库。这是对我的情况overkill。

There are 6 entries in the list. However the library I added required a Cursor object that talks to a DB. This is overkill for my situation.

有没有办法创建一个Cursor对象，基于内存的数据结构，如数组？是否有一种方法可以使用硬编码的数组作为我的Cursor？

Is there a way to create a Cursor object that is based on a memory-based data structure like an array? Is there a way I can used a hard-coded array as my Cursor?

谢谢

推荐答案

查看 MatrixCursor 文档。请检查此示例。

String[] columns = new String[] { "_id", "item", "description" };

MatrixCursor matrixCursor= new MatrixCursor(columns);
startManagingCursor(matrixCursor);

matrixCursor.addRow(new Object[] { 1, "Item A", "...." });

SimpleCursorAdapter adapter = 
        new SimpleCursorAdapter(this, R.layout.layout_row, matrixCursor, ...);

setListAdapter(adapter);
