Question

我在我的布局中开发了一个带有viewpager和pagertabstrip的应用程序。我的问题是，当我在pagertabstrip上向左或向右滑动时，它显示我不想要的左页或右页。我究竟想要的是，在pagertabstrip上滑动时，只有pagertabstrip中的标题应向左或向右移动。选择标题时，它应显示特定页面。希望我的问题清楚。这是我的代码

public class ViewPagerAdapter extends FragmentPagerAdapter {

    // Declare the number of ViewPager pages
    final int PAGE_COUNT = 10;
    private String titles[] = new String[] { "English", "Hindi","Assamese","Marathi","Telugu","Gujarati","Bengali","Kannada","Malayalam","Tamil"};

    public ViewPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        switch (position) {

            // Open FragmentTab1.java
        case 0:
            //View view=LayoutInflater.from(ViewPagerAdapter.this)
            FragmentTab1 fragmenttab1 = new FragmentTab1();
            return fragmenttab1;
            //View view=LayoutInflater.from(R.layout.web);

            // Open FragmentTab2.java
        case 1:
            FragmentTab2 fragmenttab2 = new FragmentTab2();
            return fragmenttab2;

        case 2:

            FragmentTab3 fragmenttab3=new FragmentTab3();
            return fragmenttab3;
        case 3:
            FragmentTab4 fragmenttab4=new FragmentTab4();
            return fragmenttab4;

        case 4:
            FragmentTab5 fragmenttab5=new FragmentTab5();
            return fragmenttab5;
        case 5:

            FragmentTab6 fragmenttab6=new FragmentTab6();
            return fragmenttab6;
        case 6:
            FragmentTab7 fragmenttab7=new FragmentTab7();
            return fragmenttab7;
        case 7:
            FragmentTab8 fragmenttab8=new FragmentTab8();
            return fragmenttab8;

        case 8:
            FragmentTab9 fragmenttab9=new FragmentTab9();
            return fragmenttab9;
        case 9:
            FragmentTab10 fragment10=new FragmentTab10();
            return fragment10;
        }
        return null;
    }

    public CharSequence getPageTitle(int position) {
        return titles[position];
    }

    @Override
    public int getCount() {
        return PAGE_COUNT;
    }
}

public class WebFragment extends SherlockFragment {

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        View view=inflater.inflate(R.layout.web,container,false);
        ViewPager mviewpager=(ViewPager) view.findViewById(R.id.viewPager);
        PagerTabStrip tabstrip=(PagerTabStrip) view.findViewById(R.id.pagerTabStrip);
        mviewpager.setAdapter(new ViewPagerAdapter(getChildFragmentManager()));
        final int pageMargin=(int)TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 4, getResources().getDisplayMetrics());
        mviewpager.setPageMargin(pageMargin);
        tabstrip.setGravity(Gravity.LEFT);
        return view;
    }

    @Override
    public void onDetach() {
        super.onDetach();
        try {
            Field childFragmentManager = Fragment.class
                .getDeclaredField("mChildFragmentManager");
            childFragmentManager.setAccessible(true);
            childFragmentManager.set(this, null);
        } catch (NoSuchFieldException e) {
            throw new RuntimeException(e);
        } catch (IllegalAccessException e) {
            throw new RuntimeException(e);
        }
    }
}

最简单的方法是setOnTouchListener并为ViewPager返回true。

mviewpager.setOnTouchListener(new OnTouchListener()
{           
    @Override
    public boolean onTouch(View v, MotionEvent event)
    {
        return true;
    }
});

另一个解决方案是你需要继承你的viewpager

import android.content.Context;
import android.support.v4.view.ViewPager;
import android.util.AttributeSet;
import android.view.MotionEvent;
public class CustomViewPager extends ViewPager {

public CustomViewPager (Context context) {
    super(context);
}

public CustomViewPager (Context context, AttributeSet attrs) {
    super(context, attrs);
}

@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
    // Never allow swiping to switch between pages
    return false;
}

@Override
public boolean onTouchEvent(MotionEvent event) {
    // Never allow swiping to switch between pages
    return false;
}

}

和你的xml

<youpackage.CustomViewPager 
android:id="@+id/view_pager"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
