这是我的 ListView 适配器类，当打印 ListView 时，每个 ListView 项中有一个按钮 YES 或 No。我想当我们点击是按钮时，只有 itemclik 应该工作我的意思是点击一个项目我应该进入另一个 Activity 如果我们点击否按钮那么它不应该工作项目点击意味着在列表项目上点击我不应该去另一个 Activity

下面是 ListView 屏幕:

请检查我是否已编辑您的代码。 yesimage 是你的勾选图像按钮。在您的 Notifcationadapter 类中更新以下代码。

     holder.yesimage.setOnClickListener(new OnItemClickListener( position ));

      private class OnItemClickListener  implements OnClickListener{           
             private int mPosition;         
             OnItemClickListener(int position){
                   mPosition = position;
            }          
           @Override
            public void onClick(View arg0) {    
               context.onItemtickClick(mPosition);           
           }               
     }  

在您的主页 Activity 中，为 onItemtickClick 添加以下代码。

      public void onItemtickClick(int mPosition) {
        // TODO Auto-generated method stub
           Intent i = new Intent(HomeActivity.this,RoutePathActivity.class);    
            i.putExtra("lat", Latreccvier);
            i.putExtra("lon", Lonreccvier); 
            startActivity(i);
      }
