获取PagerSlidingTabStrip页面标题onPageSelected

Question

我试图从PagerSlidingTabStrip中获取所选页面标题以显示在吐司上。页面标题是从动态列表生成的。我能够获得当前页面位置以显示在烤面包上使用：

  tabStrip.setOnPageChangeListener(new ViewPager.OnPageChangeListener() { 
     @Override 
     public void onPageSelected(int position) { 
      Toast.makeText(getActivity(), "Page position: " + position, Toast.LENGTH_SHORT).show(); 


     } 

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

     } 

     @Override 
     public void onPageScrollStateChanged(int state) { 

     } 
    }); 

如何获取当前/选定的页面标题？

Answer 1

为PagerSlidingTabStrip创建您自己的适配器（这是一个viewpager吧？），它将管理标题和位置。

ViewPager viewPager; 
ViewPagerAdapter vpAdapter; 

在mainActivity

viewPager = (ViewPager) findViewById(R.id.pager); 
     vpAdapter = new ViewPagerAdapter(getSupportFragmentManager(), 2, this, clock, history); 

ViewPagerAdapter

public class ViewPagerAdapter extends FragmentPagerAdapter { 
    private int nTabs; 
    private Context context; 
    private Fragment fragment1, fragment2; 
    private CharSequence[] titles; 

    public ViewPagerAdapter(FragmentManager fm, int nTabs, Context context, Fragment fragment1, Fragment fragment2) { 
     super(fm); 
     this.fragment1= fragment1; 
     this.fragment2= fragment2; 
     this.context =context; 
     this.nTabs = nTabs; 
     titles = new CharSequence[]{context.getText(R.string.Title_tab1), context.getText(R.string.Title_tab2)}; 
    } 




    @Override 
    public Fragment getItem(int position) { 

     switch (position) { 
      case 0: 
       return fragment1; 
      case 1: 
       return fragment2; 
      default: 
       return fragment1; 
     } 


    } 


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


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

，不要忘记设置适配器上的viewpager

viewPager.setAdapter(vpAdapter);
