FrameLayout和Fragment处理Android应用UI布局实例

TitlesFragment
TitlesFragment继承自Fragment的子类ListFragment，使用了一个静态数组填充列表，重写了onListItemClick方法，showDetails方法展示ListView item的详情。

DetailsFragment df = DetailsFragment.newInstance(index);//获取详情Fragment的实例
FragmentTransaction ft = getFragmentManager().beginTransaction();//获取FragmentTransaction 实例
ft.replace(R.id.details, df); //使用DetailsFragment 的实例
ft.setTransition(FragmentTransaction.TRANSIT_FRAGMENT_FADE);
ft.commit();//提交

看一下DetailsFragment ：

public class DetailsFragment extends Fragment { 
 
 /**  * Create a new instance of DetailsFragment, initialized to  * show the text at 'index'.  */ 
 public static DetailsFragment newInstance(int index) { 
  DetailsFragment f = new DetailsFragment(); 
  // Supply index input as an argument.   
  Bundle args = new Bundle(); 
  args.putInt("index", index); 
  f.setArguments(args); 
  return f; 
 } 
 
 @Override 
 public View onCreateView(LayoutInflater inflater, ViewGroup container, 
   Bundle savedInstanceState) { 
  if (container == null) {    
   return null; 
  } 
  ScrollView scroller = new ScrollView(getActivity()); 
  TextView text = new TextView(getActivity()); 
 
  int padding = (int) TypedValue.applyDimension( 
    TypedValue.COMPLEX_UNIT_DIP, 4, getActivity().getResources() 
      .getDisplayMetrics()); 
  text.setPadding(padding, padding, padding, padding); 
  scroller.addView(text); 
  text.setText(Shakespeare.DIALOGUE[getArguments().getInt("index", 0)]); 
  return scroller; 
 } 
} 

 
DetailsFragment 中使用newInstance(int index)方法产生DetailsFragment 实例并接受整型参数，重载了onCreateView方法创建view。
