android - 如何从 ListView SimpleCursorAdaptor 访问项目

Question

我正在使用 SimpleCursorAdaptor 加载一个包含 2 列的列表视图。代码是：

        mCursor = managedQuery(MyobiliseData.CONTENT_URI, projection, null, null, null);

    //3. Attach the data to the listview using an adaptor
    SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, 
            R.layout.list_item_custom_font, 
            mCursor, 
            new String[]{MyobiliseData.Columns.CUSTOMER_NAME,MyobiliseData.Columns.ADDRESS},
            new int[] {R.id.text1,R.id.text2}
            );
     listView1.setAdapter(adapter);

When an item in the list is selected I am trying to access the data, but I am not sure what type of object to use - when I use a HashMap object, it fails, ie

HashMap<String, String> item =  (HashMap<String,String>) listView1.getAdapter().getItem(position);

非常感谢任何帮助。

谢谢

您可以从游标获取特定索引上的项目，使用如下：

listView1.setOnItemClickListener(new OnItemClickListener()
{
    public void onItemClick(AdapterView adapterView, View view, int position, long id)
    {
         mCursor.moveToPosition(position);
         String customerName=mCursor.getString(mCursor.getColumnIndex(MyobiliseData.Columns.CUSTOMER_NAME));
         String address=mCursor.getString(mCursor.getColumnIndex(MyobiliseData.Columns.ADDRESS));
         //Use CustomerName and address
    }
});
