Answer 1

下面是对于像我这样的新手答案...

<ImageView 
    android:id="@+id/list_item_iv_icon_cross" 
    android:layout_width="30dp" 
    android:layout_height="30dp" 
    android:layout_alignParentRight="true" 
    android:clickable="true" 
    android:contentDescription="@string/app_name"   
    android:src="@drawable/cross_selector" 
    android:onClick="onCrossClick" /> 

我使用的onClick上项目，并获得在其有位置被点击我使用

final int position = listView.getPositionForView((View) v.getParent()); 

全部代码： -

public void onCrossClick(View v) { 

    final int position = listView.getPositionForView((View) v.getParent()); 
    Toast.makeText(this, "click on button " + position, Toast.LENGTH_LONG) 
      .show();   
} 

Answer 2

以下是为捕获列表项选择事件的列表视图设置侦听器的代码。

listView.setOnItemClickListener(new OnItemClickListener() { 

     @Override 
     public void onItemClick(AdapterView<?> list, View view, int position, 
       long id) { 
      // To get the item from the list use the position value 
      Object yourObject = yourAdapter.getItem(position);         
     } 
    }) 

Answer 3

检查下面的示例代码：

public class ListViewAdapter_test extends BaseAdapter { 

      private LayoutInflater mInflater; 

      public ListViewAdapter_test(Context con) { 
       // TODO Auto-generated constructor stub 
       mInflater = LayoutInflater.from(con); 
      } 

      public int getCount() { 
       // TODO Auto-generated method stub 
       return a_product_id.size(); 
      } 

      public Object getItem(int position) { 
       // TODO Auto-generated method stub 
       // return product_id1.size(); 
       return position; 
      } 

      public long getItemId(int position) { 
       // TODO Auto-generated method stub 
       // return product_id1.get(position).hashCode(); 
       return position; 
      } 

      public View getView(final int position, View convertView, 
        ViewGroup parent) { 
       // TODO Auto-generated method stub 
       final ListContent holder; 
       View v = convertView; 
       if (v == null) { 
        v = mInflater.inflate(R.layout.scan_row1, null); 
        holder = new ListContent(); 

        holder.name = (TextView) v.findViewById(R.id.sc_textname); 

        holder.name1 = (TextView) v.findViewById(R.id.sc_review); 

        holder.ratings = (RatingBar) v.findViewById(R.id.sc_ratingBar1); 

        holder.total_rate = (Button) v.findViewById(R.id.button1); 

        holder.img_p = (ImageView) v.findViewById(R.id.image_prod); 

        // holder.total_rate.setOnClickListener(mOnTitleClickListener1); 


        v.setTag(holder); 
       } else { 

        holder = (ListContent) v.getTag(); 
       } 


       holder.total_rate.setOnClickListener(mOnTitleClickListener3); 

       holder.img_p.setOnClickListener(mOnTitleClickListener_image); 

       return v; 
      } 
     } 

     static class ListContent { 

      ImageView img_p; 
      TextView name1; 
      TextView name; 
      RatingBar ratings; 
      Button total_rate; 

     } 

     public OnClickListener mOnTitleClickListener3 = new OnClickListener() { 
      public void onClick(View v) { 
       final int position = list_v 
         .getPositionForView((View) v.getParent()); 

       Log.d("you are click on Ratings","you are click on Ratings"); 

      } 
     }; 

      public OnClickListener mOnTitleClickListener_image = new OnClickListener() { 
      public void onClick(View v) { 
       final int position = list_v 
         .getPositionForView((View) v.getParent()); 

       Log.d("you are click on image view","you are click on image view"); 


      } 
     };
