我试图显示在列表视图图像的列表，但

-1

我与Android合作，改造调用API网络服务的数据被成功接收我只有第一项从列表中，但是当我试图显示图像的列表我的布局结果只有第一个图像，虽然图像阵列的尺寸上.. 我的活动是：CityActivity获得城市信息，如姓名，并说明和城市形象的名单.. 和城市形象，这个问题我已经这我问了一下我的代码： CityActivity：我试图显示在列表视图图像的列表，但

中添加此列表器其实你面临的是什么问题？ –

我只能从我的布局列表视图图像列表（一个3图像，例如）获得第一个图像... @UpendraShah –

不能在滚动视图使用一个ListView所以ListView的触摸听者加入处理滚动的列表视图比滚动列表时你可以查看所有图像。因此，在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; 
      } 
     });

非常感谢..现在它的工作!! :) –

添加这个方法在你ImageAdapter类：

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; 

} 
    }

感谢您的重播...但我有这个错误“的getItem（INT ）'in'（My Package name）.CustomDrawerAdapter'与'android.widget.ArrayAdapter'中的'getItem（int）'冲突; ？尝试使用不兼容的返回类型，”因为我的类扩展ArrayAdapter ，我该如何解决 –

其更改为BaseAdapter：=>公共类ImagesAdapter延伸BaseAdapter { –

@HayaSVU此将其更改为BaseAdapter：=>公共类ImagesAdapter延伸BaseAdapter { –

补充一点：

@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; 
}

感谢您对我的重播没有事情是甚至改变。 ..但我有这个错误“的getItem（INT）”“（我的包名）.CustomDrawerAdapter”冲突与“android.widget.ArrayAdapter”的getItem（INT）';尝试使用不兼容的返回类型，”因为我的课扩展ArrayAdapter ，我如何解决它？ –

更改为BaseAdapter –

对不起，但问题未解决..我不知道我错过了什么..你可以在github上查看我的代码吗？ https://github.com/haya51033/TravelAndTourism-master1 –
