一个片段类的多个实例

Question

我想创建一个viewpager，将包含几页，事情是，所有的页面将看起来相同（只是不同的数据），所以我创建了一个片段类，我试图添加到同一类的viewpager适配器实例...但我不能..

我该如何使viewpager每个页面是同一个片段类的实例？ 含义：相同的设计 - 不同的数据

编辑... 我从这里通用代码... http://tamsler.blogspot.co.il/2011/10/android-viewpager-and-fragments.html

和twicked它，有点

public class MainActivity extends FragmentActivity { 

private com.example.trying1.PagerAdapter mAdapter; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    initPaging(); 
} 

private void initPaging() { 
    List<Fragment> fragments = new ArrayList<Fragment>(); 
    NoteFragment nf = new NoteFragment(); 
    Bundle bundle = new Bundle(); 
    bundle.putString("noteTitle", "A"); 
    nf.setArguments(bundle); 

    NoteFragment nf1 = new NoteFragment(); 
    Bundle bundle1 = new Bundle(); 
    bundle1.putString("noteTitle", "B"); 
    nf1.setArguments(bundle1); 

    fragments.add(nf); 
    fragments.add(nf1); 
    this.mAdapter = new com.example.trying1.PagerAdapter(
      getSupportFragmentManager(), fragments); 

    ViewPager vPager = (ViewPager) findViewById(R.id.pager); 
    vPager.setAdapter(this.mAdapter); 
} 

}

你可以。您是否收到错误或数据没有更新？

编辑：

这也取决于你如何编码的片段，接受作为参数，并计算页？

public class MainActivity extends FragmentActivity { 

private MyFragmentPagerAdapter mAdapter;  
private List<Fragment> fragments; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    initPaging(); 
} 

private void initPaging() { 
    fragments = new ArrayList<Fragment>(); 
    this.mAdapter = MyFragmentPagerAdapter(
      getSupportFragmentManager()); 
    ViewPager vPager = (ViewPager) findViewById(R.id.pager); 

    //Add 3 fragments 
    for(int i =0; i<3; i++) 
     addFragments(i); 

    //Set adapter  
    vPager.setAdapter(this.mAdapter); 
} 

private void addFragments(int i){ 
    NoteFragment nf = new NoteFragment(i); //Pass data to the fragment, so it can process it 
    //You may pass it as a bundle if you wish 
    fragments.add(nf) 
}  

//适配器代码

private static class MyFragmentPagerAdapter extends FragmentPagerAdapter { 

      public MyFragmentPagerAdapter(FragmentManager fm) { 
       super(fm); 
      } 

      @Override 
      public Fragment getItem(int index) {  
       return fragments.get(index); 
      } 

      @Override 
      public int getCount() {  
       return fragments.size(); 
      } 
     } 

}
