AdaptViewView Gridview не освежает, он показывает странный отклик (несколько раз это освежает несколько раз)

Question

Я устанавливаю адаптер gridview на фрагмент. этот фрагмент прикреплен к макету пейджера представления, а viewpager привязан к активности. Я проверил данные arraylist обновлен, но просмотр не освежает.

Мой код:

Установка адаптера в OnCreate деятельности ::

for(ArrayList<Item> newLst : updateList){ 
    newPropertySubList.add(newLst); 
} 
Log.e("newPropertySubList","newPropertySubList"+newPropertySubList.size()); 
adapter = new PropertyPagerAdapetr(getSupportFragmentManager()); 
//propertyViewPager.setAdapter(adapter); 
adapter.notifyChangeInPosition(1); 
propertyViewPager.setAdapter(adapter); 
adapter.notifyDataSetChanged(); 
mIndicator.setViewPager(propertyViewPager); 

PropertyPagerAdapetr является: в этом разделе код GridviewFragment создается новый экземпляр, когда адаптер установки.

public class PropertyPagerAdapetr extends FragmentPagerAdapter {   
    private long baseId = 0; 
    public PropertyPagerAdapetr(FragmentManager fm) { 
    super(fm); 
    } 

    @Override 
    public Fragment getItem(int arg0) { 
    return GridViewFragment.newInstance(newPropertySubList.get(arg0)); 
    } 

    @Override 
    public long getItemId(int position) { 
    return baseId + position; 
    } 

    public void destroyAllItem(){ 
    getSupportFragmentManager().getFragments().clear(); 
    } 

    @Override 
    public int getItemPosition(Object object) { 
    return POSITION_NONE; 
    } 

    @Override 
    public int getCount() { 
    if (newPropertySubList != null && newPropertySubList.size() > 0) 
     return newPropertySubList.size(); 
    else 
     return 0; 
    }  

    public void notifyChangeInPosition(int n) { 
    // shift the ID returned by getItemId outside the range of all previous fragments 
    baseId += getCount() + n; 
    } 
}

Может быть, вы смешиваете GridLayout и GridView. Это разные сущности. В setUpGridLayout() вы раздуваете grid_view_imageviewitem и добавляете его к GridLayout, а не GridView.
