android - 从 onContextItemSelected() 上的列表获取值？

Question

您好，想知道我们能否从数据库中获取列表中定义的字段值，例如 id onContextItemSelected()？我用于创建上下文菜单的代码固定在下面，感谢您的帮助，thnx

 public boolean onContextItemSelected(MenuItem item) {

    AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();
    long clickedPosition = info.id;

    switch (item.getItemId()) {
    case NEW_MENU_ITEM:
        //callActivity(1);
        break;
    case SAVE_MENU_ITEM:
        //callActivity(2);
        break;
    }
    return super.onContextItemSelected(item);
}
@Override
public void onCreateContextMenu(ContextMenu menu, View view, ContextMenuInfo menuInfo) {
    super.onCreateContextMenu(menu, view, menuInfo);
    menu.setHeaderTitle("Options");
    menu.add(0, NEW_MENU_ITEM, 0, "Delete");
    menu.add(0, SAVE_MENU_ITEM, 1, "Rename");
}

以下代码不会从数据库中删除我的 ID

long clickedPosition = info.id;

Answer 1

 @Override
public boolean onContextItemSelected(MenuItem item) {
    AdapterView.AdapterContextMenuInfo info = (AdapterView.AdapterContextMenuInfo) item.getMenuInfo();

    Object obj = getListView().getItemAtPosition(info.position);
    String name = obj.toString();

}
