如何将自定义列表视图中的menuitem名称更新为android中的sqlite数据库？

Question

我是使用sqlite数据库的新手。我创建了一个数据库作为测试。和表作为测试。在测试表中，我创建了两列，一列是key_id，另一列是menuname。

我在test表中插入了一些menunames和key_id。然后我使用simplecursor适配器从sqlite数据库中获取menunames到自定义列表视图，然后附加到edittext：

网址包含我的输出屏幕截图。如果我在android中单击菜单按钮后在edittext中更改了一些menunames，则表示它显示了保存按钮。如果单击“保存”按钮，则表示我编辑的菜单名称被旧menunames或key_id替换：

如何将自定义列表视图中的menuitem名称更新为android中的sqlite数据库？

我试过这段代码：

         public class EditMainMenu extends Activity {
private SQLiteAdapter mySQLiteAdapter;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.editmainmenu);
    ListView listContent = (ListView) findViewById(R.id.contentlist);
    mySQLiteAdapter = new SQLiteAdapter(this);
    mySQLiteAdapter.openToWrite();
    final Cursor cursor = mySQLiteAdapter.queueAll();
    startManagingCursor(cursor);

    String[] from = new String[] { SQLiteAdapter.KEY_CONTENT };
    int[] to = new int[] { R.id.text };

    EditMainMenuListview adapter = new EditMainMenuListview(this,
            R.layout.editmainmenulistview, cursor, from, to);

    listContent.setAdapter(adapter);
    System.out.println("gouthampra");
}

public boolean onCreateOptionsMenu(Menu menu) {
    // TODO Auto-generated method stub
    MenuInflater inflater = getMenuInflater();
    inflater.inflate(R.menu.save, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // TODO Auto-generated method stub
    switch (item.getItemId()) {
    case R.id.save:

        break;
    case R.id.back:
        break;

    default:
        break;
    }
    return true;
}
 }

EditMainMenuListview.java

              public class EditMainMenuListview extends SimpleCursorAdapter{

Cursor c;
Context context;
Activity activity;

public EditMainMenuListview(Context context, int layout, Cursor c,
        String[] from, int[] to) {
    super(context, layout, c, from, to);

    this.c = c;
    this.context=context;
    this.activity=(Activity) context;

}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    if(convertView == null)
        convertView = View.inflate(context, R.layout.editmainmenulistview, null);
    View row = convertView;

    c.moveToPosition(position);

    EditText menuname = (EditText) convertView.findViewById(R.id.text);

  menuname.setFocusable(true);
    menuname.setText(c.getString(1));


    return(row);
}
