如何使用simpleCursorAdapter填充列表视图 [英] How to populate a listview using simpleCursorAdapter

问题描述

我有一个数据库适配器，用于从数据库表填充列表视图的布局文件。

我没有在代码中看到任何错误，但收到'应用程序已停止工作'的消息。 />
但是我觉得问题在于引发'simpleCursorAdapter ...'的行。

如果我评论该行并运行代码，则没有错误，例如'apps停止工作'。

任何人都可以帮助我，这样我就可以从Sqlite数据库中提取listview。

I have a database adapter,layout files for populating a listview from a database table.
I dont see any error in the code but get a message that 'apps has stopped working'.
However I feel that the problem lies at the line that raises the 'simpleCursorAdapter..'
If I comment that line and run the code there is NO error like 'apps stopped working'.
Can anyone help me out so that I can raise the listview from Sqlite database.

Cursor cursor= vivzHelper.getAllRows();
String [] from=new String[]{vivzHelper.NAME};
int[] to=new int[]{ R.id.item_name};
SimpleCursorAdapter dataAdapter;
dataAdapter=new SimpleCursorAdapter(this,R.layout.item_layout, cursor, from, to,0);
ListView listView = (ListView) findViewById(R.id.listView1);
listView.setAdapter(dataAdapter);

DBhelper的代码：

Code at DBhelper:

Cursor getAllRows( ){
    db = helper.getWritableDatabase();
    Cursor mCursor=null;
    String [] columns={VivzHelper.NAME};
    mCursor= db.query(VivzHelper.TABLE_NAME,columns,null,null,null,null,null);
    if (mCursor!=null) {
        mCursor.moveToFirst();
    }
    return mCursor;
}
