只掃描來自片段的圖像不完整片段

我已經創建了一個帶有一些視圖組件的片段。我只需要從該組件中僅掃描圖像，但是我的代碼完整片段正在交換。我怎樣才能交換碎片的圖像貝婁是我的代碼。我已經使用ViewPager做刷卡片段只掃描來自片段的圖像不完整片段

public class DetailedSwiperImageAdapter extends PagerAdapter { 
private Context mContext; 
FoodDetail foodDetails; 
private List<FoodDetail> foodDetailsList = new ArrayList<>(); 
private final int currentPosition; 

public DetailedSwiperImageAdapter(Context fragmentContext, List<FoodDetail> foodDetail, int position) { 
    mContext = fragmentContext; 
    foodDetailsList = foodDetail; 
    currentPosition = position; 
} 

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

@Override 
public boolean isViewFromObject(View view, Object object) { 
    return view == ((RelativeLayout) object); 
} 

@Override 
public Object instantiateItem(ViewGroup container, int position) { 
    LayoutInflater inflater = (LayoutInflater) mContext 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    View viewLayout = inflater.inflate(R.layout.detailed_fragment, container, 
      false); 
    foodDetails = foodDetailsList.get(position); 
    View view = populateDataForDetailedLayout(viewLayout, foodDetails); 
    container.addView(view); 
    return view; 
} 

/* 
    * fetch the data from the timeline and display it in the detailed screen 
    */ 
private View populateDataForDetailedLayout(View viewLayout, FoodDetail foodDetails) { 
    ((TextView) viewLayout.findViewById(R.id.detailed_meal_type)).setText(foodDetails.getFoodType().name()); 

    ImageView dishImageView = (ImageView) viewLayout.findViewById(R.id.dish_image_view); 
    File imgFile = new File(foodDetails.getFoodImageLocalPath());

    if (foodDetails.getIntentEmojiUnicode() != null) { 
     Picasso.with(mContext).load(RemoteUtils.getIntentImageURIString(foodDetails.getIntentEmojiUnicode(), null, "khanapal")).into(emojiImage); 

    } 

    CharSequence time = DateUtils.getRelativeDateTimeString(mContext, 
      foodDetails.getStartTime().getTime(), DateUtils.MINUTE_IN_MILLIS, DateUtils.WEEK_IN_MILLIS, 0); 
    detaileTime.setText(time); 
    String location = ""; 

    if (!TextUtils.isEmpty(foodDetails.getStreet())) { 
     location = foodDetails.getStreet(); 
    } else if (!TextUtils.isEmpty(foodDetails.getLocationName())) { 
     location = foodDetails.getLocationName();

    location += " - " + foodDetails.getLocationUnformattedAddress() + ""; 
    if (foodDetails.getLocationUnformattedAddress() == null) location = "No location"; 
    detaileLocation.setText(location); 

    //used for message edting on click of smart message text editor 
    detaileMessage.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View v) { 
      String message = detaileMessage.getText().toString(); 
      editMessage(message, detaileMessage); 
     } 
    }); 
    return viewLayout; 
}

}
