List View中的Android ViewPager

Question

我是滑動圖像視圖的問題。

我用這個library

我需要進口在我的項目，但我有一個問題。

我想用在listview中的每一行。但在我listviewAdapter是highlighteed代碼（代碼做刷卡ImageView的）更準確getSupportFragmentManager()]

代碼從庫中使用

Fragment demoFragment = Fragment.instantiate(activity, AnimationFragment.class.getName()); 
     FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction(); 
     fragmentTransaction.replace(R.id.fragment_container, demoFragment); 
     fragmentTransaction.commit(); 

    getSupportFragmentManager().addOnBackStackChangedListener(
      new FragmentManager.OnBackStackChangedListener() { 
       @Override public void onBackStackChanged() { 
        int count = getSupportFragmentManager().getBackStackEntryCount(); 
       } 
      }); 

我的事情，所以需要AppCompatActivity但如何我，如果我在列表視圖得到appcompatactivity適配器？

或如何得到這樣的事情在這裏

ListviewAdapter 公共類ListViewAdapter延伸BaseAdapter {

Activity activity; 
List<Kon> listKone; 
LayoutInflater inflater; 
Bitmap bitmapOriginal; 

ProgressBar progressBar; 


public ListViewAdapter(Activity activity, List<Kon> listKone) { 
    this.activity = activity; 
    this.listKone = listKone; 
} 

@Override 
public int getCount() { 
    return listKone.size(); 
} 

@Override 
public Object getItem(int i) { 
    return listKone.get(i); 
} 

@Override 
public long getItemId(int i) { 
    return i; 
} 

@Override 
public View getView(final int i, View view, ViewGroup viewGroup) { 


    inflater = (LayoutInflater)activity.getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    View itemView = inflater.inflate(R.layout.listview_item,null); 

    TextView txtUser = (TextView)itemView.findViewById(R.id.list_name); 
    TextView txtBorn = (TextView)itemView.findViewById(R.id.list_born); 
    TextView txtcena = (TextView)itemView.findViewById(R.id.list_cena); 
    TextView txtplemeno = (TextView)itemView.findViewById(R.id.list_plemeno); 
    ImageView imgHorse=(ImageView)itemView.findViewById(R.id.imageHorse); 
    ImageView imgHorseB=(ImageView)itemView.findViewById(R.id.imageHorseB); 
    progressBar= (ProgressBar) itemView.findViewById(R.id.progressBar2) ; 

    txtUser.setText(listKone.get(i).getName()); 
    txtBorn.setText(listKone.get(i).getNarodenie()); 
    txtcena.setText(listKone.get(i).getCena()); 
    txtplemeno.setText(listKone.get(i).getPlemeno()); 
    // Then later, when you want to display image 

    if (listKone.get(i).getCestaObrazok()!=null) { 
     ImageLoader.getInstance().displayImage(listKone.get(i).getCestaObrazok(), imgHorse); 

     BitmapDrawable drawable = (BitmapDrawable) imgHorse.getDrawable(); 
     Bitmap bitmap = null; 
     try { 
      bitmap = drawable.getBitmap(); 
     } catch (NullPointerException e){ 
     } 



     while ((drawable==null)||(bitmap==null)) { 
      ImageLoader.getInstance().displayImage(listKone.get(i).getCestaObrazok(), imgHorse); // Default options will be used 
      //ImageLoader.getInstance().displayImage(listKone.get(i).getCestaObrazok(), imgHorseB); // Default options will be used 
      // ImageLoader.getInstance().displayImage(listKone.get(i).getCestaObrazok(), imgHorseB); // Default options will be used 

      drawable = (BitmapDrawable) imgHorse.getDrawable(); 
      try { 
       bitmap = drawable.getBitmap(); 
      } catch (NullPointerException e){ 
      // Toast.makeText(activity, "drawable null", Toast.LENGTH_SHORT).show(); 
      } 
      // imgHorseB.setImageBitmap(bitmap); 
     } 
     Bitmap blurred = blurRenderScript(activity, bitmap, 25); 
     imgHorseB.setScaleType(ImageView.ScaleType.FIT_XY); 
     imgHorseB.setImageBitmap(blurred); 
    } 
    return itemView; 
}

使用這個庫：https://github.com/ongakuer/CircleIndicator

這是非常簡單的。在XML：

<me.relex.circleindicator.CircleIndicator 
     android:id="@+id/indicator" 
     android:layout_width="match_parent" 
     android:layout_height="48dp"/> 

在Java類：

ViewPager viewpager = (ViewPager) view.findViewById(R.id.viewpager); 
CircleIndicator indicator = (CircleIndicator) view.findViewById(R.id.indicator); 
viewpager.setAdapter(new SamplePagerAdapter(listKone,i,activity)); 
indicator.setViewPager(viewpager);
