更改片段按钮上的FragmentPagerAdapter适配器位置单击

我正在开发Android应用程序。在我的应用程序中，我必须使用5个片段，然后从片段1滑动到5。所以我使用了一个FragmentActivity，FragmentPagerAdapter和5个片段。现在，我可以浏览所有片段，并可以通过使用标识当前片段

ViewPager.OnPageChangeListener()

我必须在所有片段中添加按钮，并且单击按钮必须像滑动一样打开下一个片段。我该怎么办？在这里，我发布了一些代码片段。

fragmentactivity.java

public class HomeScreen extends FragmentActivity 
{
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.themed_circles);

    mAdapter = new InsuranceFragmentAdapter(getSupportFragmentManager(),
            HomeScreen.this);
    mPager = (ViewPager) findViewById(R.id.pager);
    mPager.setAdapter(mAdapter);
    mIndicator = (CirclePageIndicator) findViewById(R.id.indicator);
    mIndicator.setViewPager(mPager);
    // mIndicator.setCurrentItem(2);

    mIndicator
            .setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
                private int pos;

                @Override
                public void onPageSelected(int position) {

                }

                @Override
                public void onPageScrolled(int position,
                        float positionOffset, int positionOffsetPixels) {


                }

                @Override
                public void onPageScrollStateChanged(int state) {
                    System.out.println("test scroll state" + state);

                }
            });
}

  }

以下是我用于刷片段的FragmentPagerAdapter。

FragmentPagerAdapter.java


public class InsuranceFragmentAdapter extends FragmentPagerAdapter {
Context contx;


public InsuranceFragmentAdapter(FragmentManager fm, Context ctx) {

    super(fm);
    this.contx = ctx;


}

@Override
public Fragment getItem(int position) {
    Fragment fragment = null;
    switch (position) {
    case 0:
        fragment = Fragment.instantiate(contx, com.lic.fragments.FragmentBasicPersonal.class.getName());
        break;

    case 1:
        fragment = Fragment.instantiate(contx, com.lic.fragments.FragmentationNomineeDetails.class.getName());
        break;

    }

    return fragment;
}

@Override
public int getCount() {

    return 2;
}



public void setCount(int count) {

}

}

我的片段之一如下。fragment_one.java

public class FragmentFemale extends Fragment {

   @Override
   public void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);

   }

   @Override
   public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View layout = inflater.inflate(R.layout.fragment_female_husband, container, false);
            next= (Button) layout.findViewById(R.id.save);
            next.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
                   //need to change to next fragment
          }
            }
       return layout;
   }

   @Override
   public void onSaveInstanceState(Bundle outState) {
       super.onSaveInstanceState(outState);
     //  outState.putString(KEY_CONTENT, mContent);
   }
}
