Android viewpager中的三个片段

我有这个问题，如下图所示：

一, 二,

我已经用三个片段完成了一个viewpager，但是当滚动时，我看到其中一个片段，我会看到两个片段

我的理由是：

公共类FragmentProjetSwipePageActivity扩展了FragmentActivity{

// derived from http://thepseudocoder.wordpress.com/2011/10/05/android-page-swiping-using-viewpager/


// list contains fragments to instantiate in the viewpager
List<Fragment> fragmentsV1 = new Vector<Fragment>();

// page adapter between fragment list and view pager
private PagerAdapter mPagerAdapter;
// view pager
private ViewPager mPager;


// activity data
public String p2text,p3text;

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


    // creating fragments and adding to list
    fragmentsV1.add(Fragment.instantiate(this,Page1Fragment.class.getName()));
            fragmentsV1.add(Fragment.instantiate(this,Page2Fragment.class.getName()));
    fragmentsV1.add(Fragment.instantiate(this,Page3Fragment.class.getName()));



    // creating adapter and linking to view pager
    mPager = (ViewPager) super.findViewById(R.id.pager1);
    this.mPagerAdapter = new PagerAdapter(super.getSupportFragmentManager(),fragmentsV1,this );
    mPager.setAdapter(this.mPagerAdapter);


    //Set a listener that will be invoked whenever the page changes or is incrementally scrolled.

} }

PagerAdapter.java

公共类PagerAdapter扩展了FragmentPagerAdapter{

// fragments to instantiate in the viewpager
private List<Fragment> fragments;
FragmentManager fm;
private static int NUM_PAGER_VIEWS = 2;

Context contex;

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

}

// return access to fragment from position, required override
@Override
public Fragment getItem(int position) {


    return this.fragments.get(position);
}

// number of fragments in list, required override
@Override
public int getCount() {

    return NUM_PAGER_VIEWS;
    //return this.fragments.size();

} 

}

谢谢

你知道已经有一个名为PagerAdapter的内置类了吗@Enigma FragmentPagerAdapter是PageAdapterWell的扩展，我知道。你的情况正好相反。您正在从FragmentPagerAdapter扩展PagerAdapter。@Enigma抱歉，我不明白，如果我在PageHandler中更改类PagerAdapter的名称，结果是一样的。如何解决上图中的问题？我需要一个活动中有2个视图的viewpager，但每次滚动一个视图，总共有3个视图。
