疊加的動作條圖標

Question

有沒有人看過這個問題？這只是使用薑餅設備的模擬器，但我的應用程序有ViewPager，當我從初始視圖滑動到另一個視圖並回到初始視圖時，它看起來像另一組圖標疊加在初始圖標Actionbar（使用ActionbarSherlock）：

初始：

滑動後（通知圖標是更厚）：

這不會發生在僅ICS +設備薑餅。

ViewPager：

public class Main extends SherlockFragmentActivity 
{ 
    private static List<Integer> mIds; 
    private static SparseArray<Fragment> mPageReferenceMap = new SparseArray<Fragment>(); 

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

     setContentView(R.layout.main); 

     mViewPager = (ViewPager)findViewById(R.id.viewpager); 
     mMyFragmentPagerAdapter = new MyFragmentPagerAdapter(getSupportFragmentManager()); 
     mViewPager.setAdapter(mMyFragmentPagerAdapter); 

     mViewPager.setOnPageChangeListener(new OnPageChangeListener() { 

      @Override 
      public void onPageSelected(int position) { 
       GetListingFragment().StopAnimation(); //needed to add this because the ActionView was showing on the other views when swiping 
      } 

      @Override 
      public void onPageScrolled(int position, float offset, int offsetPixel) { 
      } 

      @Override 
      public void onPageScrollStateChanged(int state) { 

      } 
     }); 

     mIds = new ArrayList<Integer>(); 

     mIds.add(0); 
     mIds.add(1); 
     mIds.add(2); 
    } 

    @Override 
    public void onResume() 
    { 
     super.onResume(); 
     ActivityCompat.invalidateOptionsMenu(this); 
    } 

    private ListingFragment GetKeywordsFragment() 
    {  
     ListingFragment lf = (ListingFragment)getSupportFragmentManager().findFragmentById(R.id.fragmentListing); 

     if (lf == null) 
     { 
      final MyFragmentPagerAdapter fpa = (MyFragmentPagerAdapter)mViewPager.getAdapter(); 
      lf = (ListingFragment)fpa.getFragment(0); 
     } 

     return lf; 
    } 

    private static class MyFragmentPagerAdapter extends FragmentStatePagerAdapter { 

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

     @Override 
     public Fragment getItem(int index) { 
      if (index == 0) 
      { 
       final ListingFragment lf = ListingFragment.newInstance(); 
       mPageReferenceMap.put(index, lf); 
       return lf; 
      } 
      else 
      { 
       final DetailFragment df = DetailFragment.newInstance(mIds.get(index)); 
       mPageReferenceMap.put(index, df); 
       return df; 
      } 
     } 

     public Fragment getFragment(int key) { 
      return mPageReferenceMap.get(key); 
     } 

     @Override 
     public int getCount() { 
      return 3; 
     } 
    } 
}
