【问题描述】：
我有一个来自画廊的 onclick 监听器，它应该清除 tableview 内的所有行，然后将行/行添加到滚动视图内的 tableview。每次单击按钮时，片段都会发生变化。
但是我得到：java.lang.IllegalStateException: ScrollView 只能托管一个直接子级。
我的活动按钮监听器
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();
跟踪器片段
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 container,
Bundle savedInstanceState)
{
View v = inflater.inflate(R.layout.tracker, container, false);
TableLayout tableLayout = (TableLayout) v.findViewById(R.id.tracker_layout);
tableLayout.removeAllViews();
if (dish != null)
{
//display others
//display subsystem stuff
for (int i = 0; i < dish.getSubsystems().size(); i++)
{
TableRow tableRow = new TableRow(v.getContext());
tableRow.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
TextView tv = new TextView(v.getContext());
tv.setText(dish.getSubsystems().get(i).getConnFuncAddr());
tableRow.addView(tv);
tableLayout.addView(tableRow);
}
}
else
{
TableRow tableRow = new TableRow(v.getContext());
tableRow.setLayoutParams(new LayoutParams(LayoutParams.FILL_PARENT,LayoutParams.WRAP_CONTENT));
TextView tv = new TextView(v.getContext());
tv.setText("Click on image to view more data");
tableRow.addView(tv);
tableLayout.addView(tableRow);
}
return v;
}
}

有谁知道怎么回事？我猜我正在向滚动视图而不是表格视图添加一个表格行，但是，我没有看到我在代码中做错了什么。
