無法安裝類型PagerAdapter？怎麼了？

嘿傢伙我試圖刷我的活動之間使用PagerAdapter但我得到錯誤這裏是我的代碼，我有點新的Android開發，所以我無法理解我發現的問題互聯網上的解決方案。任何人都可以告訴我如何完全修復它？任何幫助將不勝感激，謝謝！這裏是我的代碼：無法安裝類型PagerAdapter？怎麼了？

PagerAdapter.java： -

package com.example.prototype; 

import java.util.List; 

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

public class PagerAdapter extends FragmentPagerAdapter { 

    private List<Fragment> fragments; 

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

    } 

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

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

ViewPagerFragmentActivity： -

package com.example.prototype; 

import java.util.List; 
import java.util.Vector; 

import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentActivity; 
import android.support.v4.view.PagerAdapter; 
import android.support.v4.view.ViewPager; 

import com.example.prototype.R; 
import com.example.prototype.Games; 
import com.example.prototype.Movies; 
import com.example.prototype.Songs; 

public class ViewPagerFragmentActivity extends FragmentActivity { 

    private PagerAdapter mPagerAdapter; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     super.setContentView(R.layout.viewpager_layout); 

     this.initialisePaging(); 
    } 

    private void initialisePaging() { 

     List<Fragment> fragments = new Vector<Fragment>(); 
     fragments.add(Fragment.instantiate(this, Games.class.getName())); 
     fragments.add(Fragment.instantiate(this, Movies.class.getName())); 
     fragments.add(Fragment.instantiate(this, Songs.class.getName())); 

     this.mPagerAdapter = new PagerAdapter(super.getSupportFragmentManager(), fragments);  //Error at this line!!! 

     ViewPager pager = (ViewPager) super.findViewById(R.id.viewpager); 
     pager.setAdapter(this.mPagerAdapter); 
    } 
}

你從框架進口PagerAdapter代替你的sublcass。在從
