我的code

My Code

public static class DummySectionFragment extends Fragment {
    public DummySectionFragment() {
    }

    public static final String ARG_SECTION_NUMBER = "section_number";

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        Log.e("555", "hello");
        return inflater.inflate(R.layout.main, null);

        /*
        TextView textView = new TextView(getActivity());
        textView.setGravity(Gravity.CENTER);
        Bundle args = getArguments();
        textView.setText(Integer.toString(args.getInt(ARG_SECTION_NUMBER)));
        return textView;*/
    }
}

main.xml中

main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="horizontal" >

    <fragment

        android:layout_height="match_parent"
        android:layout_marginTop="?android:attr/actionBarSize"
        class="com.example.testing.ListFragment" ></fragment>

    <fragment
