ViewPager片段内（NestedFragments）

Question

我的应用程序具有与抽屉式导航主活性，即允许应用程序片段之间导航。导航抽屉的每个项目列表显示一个片段。

在这些片段我想ViewPager，这里的一个是我卡住了。如果我没有错，这是另一片碎片（嵌套片段）内的碎片，但我无法完成这项工作。

这是包含ViewPager片段的代码 Seccion1.java

import android.app.Fragment; 
import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 
import android.support.v4.view.ViewPager; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 

import java.util.ArrayList; 
import java.util.List; 

public class Seccion1 extends Fragment { 

    ViewPager vp; 

    private List<android.support.v4.app.Fragment> getFragments(){ 
     List<android.support.v4.app.Fragment> list = new ArrayList<android.support.v4.app.Fragment>(); 
     list.add(ModelFragment.newInstance("Hola como andas", "descriociones")); 
     list.add(ModelFragment.newInstance("0895452125x", "#FFFFEF59")); 
     list.add(ModelFragment.newInstance("22 Mart", "#FF9C63FF")); 
     list.add(ModelFragment.newInstance("Sak", "#72a83b")); 
     list.add(ModelFragment.newInstance("Android Studio", "#a83b97")); 
     return list; 
    } 

    //@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 

     View rootView = inflater.inflate(R.layout.seccion1, container, false); 

     vp = (ViewPager)rootView.findViewById(R.id.vp); 

     //vp.setPageTransformer(true, new RotateDownTransformer()); 
     ControllerFragment cf = new ControllerFragment(getChildFragmentManager(), getFragments()); 
     vp.setAdapter(cf); 

     return rootView; 
    } 
} 

我不知道如何解决这一行：

ControllerFragment CF =新ControllerFragment（getChildFragmentManager （），getFragments（））;

这里ControllerFragment代码 ControllerFragment.java

import android.content.Context; 
import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentManager; 
import android.support.v4.app.FragmentPagerAdapter; 
import android.support.v4.view.ViewPager; 
import android.view.View; 
import android.widget.RelativeLayout; 
import android.widget.TextView; 
import java.util.List; 

public class ControllerFragment extends FragmentPagerAdapter { 
    List<Fragment> fragments; 
    Context context; 

    public ControllerFragment(FragmentManager fm, List<Fragment> fragments){ 
     super(fm); 
     this.fragments = fragments; 
    } 

    public Fragment getItem(int position){ 
     return fragments.get(position); 
    } 

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

    public Object instantiateItem(View view, int position){ 
     RelativeLayout relativeLayout = (RelativeLayout)view.inflate(context, R.layout.custom_fragment, null); 
     TextView tv_text = (TextView)relativeLayout.findViewById(R.id.tv_text); 
     TextView tv_description = (TextView)relativeLayout.findViewById(R.id.tv_description); 
     ((ViewPager) view).addView(relativeLayout); 
     return relativeLayout; 
    } 
}

更改此

import android.app.Fragment; 

到

import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentManager;
