我ScrollView在我的Android布局中使用但它显示

IllegalStateException "Scrollview can host only one direct child"

我怎样才能避免这种异常？

崩溃信息:

我只是尝试通过添加scrollview添加滚动浏览此布局的功能,但每次我尝试加载布局时,我都会收到一条错误,指出"java.lang.IllegalStateException:ScrollView只能托管一个直接子项",我不确定为什么.

任何建议都非常感谢.

我有一个来自库的onclick监听器,它应该清除tableview中的所有行,然后将行/行添加到scrollview内的tableview.每次按下按钮时,片段都应该更改.

但是我得到:java.lang.IllegalStateException:ScrollView只能托管一个直接子项.

myactivity按钮监听器

            TrackerFragment tf = (TrackerFragment) getFragmentManager().findFragmentById(R.id.tracker1);
            tf = TrackerFragment.newInstance(listOfList.get(id).get(position));

            fragmentTransaction.add(R.id.tracker1, tf);
            fragmentTransaction.commit();
            t1 = true; //being used
            getFragmentManager().executePendingTransactions();

跟踪片段

public class TrackerFragment extends Fragment
{
    private Dish dish;

    public static TrackerFragment newInstance(Serializable dish) 
    {
        TrackerFragment tf = new TrackerFragment();

        Bundle args = new Bundle();
        args.putSerializable("dish", dish);
        tf.setArguments(args);

        return tf;
    }

    public static TrackerFragment newInstance(Bundle bundle)
    {
        Dish dish = (Dish) bundle.getSerializable("dish");
        return newInstance(dish);
    }

    @Override
    public void onCreate(Bundle myBundle)
    {
        super.onCreate(myBundle);
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup …

在我的 Android 应用程序中，我面临着 IllegalStateException。我稍后无法重现此异常。这是堆栈跟踪
