jede Hilfe! und danke Aktualisieren

Answer 1

Sie können keine Listenansicht in Scrollview verwenden, so Listview Berührung listner hinzufügen handle scrolling von listview als wenn Sie blättern Liste Sie können alle Bilder anzeigen. Also fügen Sie diesen Listener in CityActivity.java

listView.setOnTouchListener(new View.OnTouchListener() { 
      // Setting on Touch Listener for handling the touch inside ScrollView 
      @Override 
      public boolean onTouch(View v, MotionEvent event) { 
       // Disallow the touch request for parent scroll on touch of child view 
       v.getParent().requestDisallowInterceptTouchEvent(true); 
       return false; 
      } 
     }); 

Answer 2

diese Methoden in Ihrem ImageAdapter Klasse hinzufügen:

public class ImagesAdapter extends BaseAdapter { 

String url = "http://www.travel-tourism1.somee.com"; 
private Context context; 
private List<Images> imagesList; 

public ImagesAdapter(Context context, int resource, List<Images> objects) { 
    super(context, resource, objects); 
    this.context = context; 
    this.imagesList = objects; 
} 



@Override 
public int getCount() { 

    return imagesList.size(); 
} 

@Override 
public Object getItem(int position) { 

    return null; 
} 

@Override 
public long getItemId(int position) { 

    return position; 
} 

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE); 
    View view = inflater.inflate(R.layout.row_image,parent,false); 


    Images image = imagesList.get(position); 
    ImageView iv = (ImageView)view.findViewById(R.id.ivImage); 
    String imgPath = image.getPath().substring(1); 
    Picasso.with(getContext()).load(url+imgPath).resize(300,300).into(iv); 


    return view; 

} 
    } 

Answer 3

hinzufügen:

@Override 
public int getCount() { 

    return imagesList.size(); 
} 

@Override 
public Object getItem(int position) { 

    return imageList.get(position); 
} 

@Override 
public long getItemId(int position) { 

    return position; 
}
