Viewpager Image在片段中滑动画廊？

我是新来的机器人..Viewpager Image在片段中滑动画廊？

我跟着这tutorial知道如何实现viewpager作为图像幻灯片刷卡画廊。现在，我想要在fragment中实施相同的图像刷卡。我不知道如何继续。由于它遵循片段，所以有另一个函数onCreateView。不知道如何继续下一步！

MainActivity.java（实施抽屉式导航用在列表视图中2个项目）

package com.example.sidemenutabstutorial; 

import android.content.res.Configuration; 
import android.os.Bundle; 
import android.support.v4.app.ActionBarDrawerToggle; 
import android.support.v4.view.GravityCompat; 
import android.support.v4.widget.DrawerLayout; 
import android.view.View; 
import android.widget.AdapterView; 
import android.widget.ListView; 

import com.actionbarsherlock.app.SherlockFragmentActivity; 

public class MainActivity extends SherlockFragmentActivity { 

DrawerLayout mDrawerLayout; 
ListView mDrawerList; 
ActionBarDrawerToggle mDrawerToggle; 
MenuListAdapter mMenuAdapter; 
String[] title; 
String[] subtitle; 
int[] icon; 
Fragment1 fragment1 = new Fragment1(); 

Fragment2 fragment2 = new Fragment2(); 

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

    // Generate title 
    title = new String[] { "Title Fragment 1", "Title Fragment 2"}; 

    // Generate subtitle 
    subtitle = new String[] { "Subtitle Fragment 1", "Subtitle Fragment 2"}; 

    // Generate icon 
    icon = new int[] { R.drawable.action_about, R.drawable.action_settings}; 

    // Locate DrawerLayout in drawer_main.xml 
    mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 

    // Locate ListView in drawer_main.xml 
    mDrawerList = (ListView) findViewById(R.id.left_drawer); 

    // Set a custom shadow that overlays the main content when the drawer 
    // opens 
    mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, 
      GravityCompat.START); 

    // Pass results to MenuListAdapter Class 
    mMenuAdapter = new MenuListAdapter(this, title, subtitle, icon); 

    // Set the MenuListAdapter to the ListView 
    mDrawerList.setAdapter(mMenuAdapter); 

    // Capture button clicks on side menu 
    mDrawerList.setOnItemClickListener(new DrawerItemClickListener()); 

    // Enable ActionBar app icon to behave as action to toggle nav drawer 
    getSupportActionBar().setHomeButtonEnabled(true); 
    getSupportActionBar().setDisplayHomeAsUpEnabled(true); 

    // ActionBarDrawerToggle ties together the the proper interactions 
    // between the sliding drawer and the action bar app icon 
    mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, 
      R.drawable.ic_drawer, R.string.drawer_open, 
      R.string.drawer_close) {

     public void onDrawerOpened(View drawerView) { 
      // TODO Auto-generated method stub 
      super.onDrawerOpened(drawerView); 
     } 
    }; 

    mDrawerLayout.setDrawerListener(mDrawerToggle); 

    if (savedInstanceState == null) { 
     selectItem(0); 
    }

     } else { 
      mDrawerLayout.openDrawer(mDrawerList); 
     } 
    } 

    return super.onOptionsItemSelected(item); 
} 

// The click listener for ListView in the navigation drawer 
private class DrawerItemClickListener implements 
     ListView.OnItemClickListener { 
    @Override 
    public void onItemClick(AdapterView<?> parent, View view, int position, 
      long id) {

    } 
} 

private void selectItem(int position) { 

    android.support.v4.app.FragmentTransaction ft = 

    getSupportFragmentManager().beginTransaction(); 
    // Locate Position 
    switch (position) { 
    case 0: 
     ft.replace(R.id.content_frame, fragment1); 
     break; 
    case 1: 
     ft.replace(R.id.content_frame, fragment2); 
     break; 
    } 
    ft.commit(); 
    mDrawerList.setItemChecked(position, true); 
    // Close drawer 
    mDrawerLayout.closeDrawer(mDrawerList); 
} 

@Override

    super.onConfigurationChanged(newConfig); 
    // Pass any configuration change to the drawer toggles 
    mDrawerToggle.onConfigurationChanged(newConfig); 
}

}

Fragment1.java

public class Fragment1 extends SherlockFragment { 

ViewPager mViewPager; 

public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 
    View rootView = inflater.inflate(R.layout.activity_main, container, false);

    ImageAdapter adapter = new ImageAdapter(getSupportFragmentManager()); 
    mViewPager.setAdapter(adapter); 

    return rootView;

}

ImageAdapter.java

    R.drawable.one, 
    R.drawable.two,

this.context=context; 
} 
public ImageAdapter(Fragment1 fragment1) { 
    // TODO Auto-generated constructor stub 
} 
@Override

return GalImages.length; 
}

imageView.setImageResource(GalImages[position]); 
((ViewPager) container).addView(imageView, 0); 
return imageView; 
} 

@Override
