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();

有谁知道什么是错的？我猜我在滚动视图中添加了一个表行而不是tableview,但是,我在代码中看不到我在做错的地方.
