如何用viewpager片段替换片段

我在左侧有一组按钮片段活动。我也创建了两个片段，webview和ViewPagerFragment与3 ImageFragments。问题是当我试图取代webview与Viewpager我不能再刷卡只有1 ImageFragment得到显示。我无法再滑过他们。如何用viewpager片段替换片段

这里是我的ImageFragment

public class ImageFragment extends Fragment { 
private int imageResourceId; 
OnClickListener listener; 
public MyAdapter mAdapter; 
public ViewPager mPager; 
public ImageFragment(){ 

} 

public static Fragment newInstance() { 
    // TODO Auto-generated method stub 
    ImageFragment mg = new ImageFragment(); 
    return mg; 
} 


public ImageFragment(int imageResourceId) { 
    this.imageResourceId = imageResourceId; 
} 


public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    Log.e("Test", "ImageFragment"); 

} 


public void onActivityCreated(Bundle savedInstanceState) { 
    super.onActivityCreated(savedInstanceState); 

} 


public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 
    View view = inflater.inflate(R.layout.image_layout, container, false); 
    View view2 = inflater.inflate(R.layout.pagerview,null); 

    mPager = (ViewPager) view.findViewById(R.id.pager); 
    Log.d("ImageFragment","mPager = "+mPager.toString()); 
    mAdapter = new MyAdapterDummy().new MyAdapter(getFragmentManager()); 
    new setAdapterTask().execute(); 


    ImageView imageView1 = (ImageView) view.findViewById(R.id.imageView1); 
    ImageView imageView2 = (ImageView) view.findViewById(R.id.imageView2); 
    ImageView imageView3 = (ImageView) view.findViewById(R.id.imageView3); 
    ImageView imageView4 = (ImageView) view.findViewById(R.id.imageView4); 
    ImageView imageView5 = (ImageView) view.findViewById(R.id.imageView5); 
    ImageView imageView6 = (ImageView) view.findViewById(R.id.imageView6); 



    imageView1.setImageResource(imageResourceId); 
    imageView2.setImageResource(imageResourceId); 
    imageView3.setImageResource(imageResourceId); 
    imageView4.setImageResource(imageResourceId); 
    imageView5.setImageResource(imageResourceId); 
    imageView6.setImageResource(imageResourceId); 



    return view; 
} 

private class setAdapterTask extends AsyncTask<Void,Void,Void>{ 
     protected Void doInBackground(Void... params) { 
      return null; 
     } 

     protected void onPostExecute(Void result) { 
        mPager.setAdapter(mAdapter); 

     } 
}

，这里是适配器

public class MyAdapterDummy extends FragmentActivity { 
static String TAG = "ViewPagerExample"; 
MyAdapter mAdapter; 
ViewPager mPager; 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 
    FragmentManager mgr = getSupportFragmentManager(); 

} 

public class MyAdapter extends FragmentPagerAdapter { 

    public MyAdapter(FragmentManager fm) { 

     super(fm); 
    } 

    public int getCount() { 
     return 3; 
    } 

    public Fragment getItem(int position) { 
     Log.d(TAG, "Item Position : " + position); 
     switch (position) { 
     case 0: 
      return new ImageFragment(R.drawable.ic_launcher); 
     case 1: 
      return new ImageFragment(R.drawable.ic_launcher); 
     case 2: 
      return new ImageFragment(R.drawable.ic_launcher); 

     default: 
      return null; 

     } 
    } 

    @Override 
    public CharSequence getPageTitle(int position) { 
     String str = "Top Listings"; 
     return str; 
    } 



}

}

任何帮助，将不胜感激。

谢谢

你有没有尝试过使用ViewPagerFragment初步核实，你想到的是它的实际工作？ –

y downvote？ ....是的，我做了....它确实工作...问题是当我整合它时，它只显示一个imageview。我无法滑动到其他图像.... ..../ – LeXeR

基本上我想用PagerView替换Webview片段，它使用3个imagefragments .... – LeXeR

我解决了这个.....

你有你的ViewPager也转换成一个片段。我知道它是一个ViewGroup，但仍然是。然后你可以用你的onclick标准替换方法替换一个片段。

以下是更改后的代码。

@Override 
public void onListItemClick(ListView l, View v, int position, long id) { 
    l.setItemChecked(position, true); 
    Fragment df = DetailsFragment.newInstance(); 
    Fragment page = FragmentPagerAdapterClass.newInstance(); 

    if (listener != null) { 
     if (position == 0) { 
      Log.d(TAG, "Position = " + position); 


      getFragmentManager().beginTransaction().remove(DetailsFragment.newInstance()); 
      getFragmentManager().beginTransaction() 
      .replace(R.id.layout_detail, FragmentPagerAdapterClass.newInstance()).commit(); 
      getFragmentManager().executePendingTransactions(); 

     } else { 
      Log.d(TAG, "Position = " + position); 

      McDonalds c = EU.get(position); 
      String url = getString(c.url); 

      new DetailsFragment().setUrl(url); 

       getFragmentManager().beginTransaction().remove(FragmentPagerAdapterClass.newInstance()); 
      getFragmentManager().beginTransaction() 
       .replace(R.id.layout_detail, DetailsFragment.newInstance()).commit(); 
      getFragmentManager().executePendingTransactions(); 

      // listener.onCountrySelected(EU.get(position)); 
     } 
    } 
}

反正....感谢名单让所有支援:)
