我是android新手。我正在开发一个应用程序。我有一个列出页面的列表页面（从mysql数据库加载）。每个列表项包含一个ImageView（酒店的图像），TextViews（用于保存特定酒店的名称，地址，价格等）。我设置了一个SimpleAdapter来设置值。并使用setViewBinder将图像（从Internet）设置为ImageView。
我的问题是，我想让ClickView（这个imageview就像整个列表项的背景）可点击。当用户点击特定的listitem（imageview）时，需要调用一个intent，我可以通过该intent展示所点击的酒店的更多细节。我想通过意图传递一些细节。 我试了很多次。我可以在列表视图中设置酒店的图像和其他详细信息。但是当我单击一个imageview时，意图只携带第一行值。
我将提供以下代码。请帮帮我。
