動態使用Fragment

            Activity

        FragmentDemo fram = new FragmentDemo();
        FragmentManager manager = getFragmentManager();
        FragmentTransaction transfo = manager.beginTransaction();
//     點擊back鍵回到剛纔的Fragment
        transfo.addToBackStack(null);
        transfo.replace(R.id.frame, fram);
        transfo.commit();

 

   Fragment

           

 public View onCreateView(LayoutInflater inflater, ViewGroup container,
   Bundle savedInstanceState) {
  View view = inflater.inflate(R.layout.fragment_01, container,false);
  return view;
 }
 @Override
 public void onActivityCreated(Bundle savedInstanceState) {
  super.onActivityCreated(savedInstanceState);
  
 }

 

 

XML

    <FrameLayout 
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:id="@+id/fram"
        ></FrameLayout>
