标签: android android-listview android-fragments simplecursoradapter

HI all,im trying a develop a sms app from scratch(smsdroid as my reference) . Basically i have Viewpager which shows the conversation list in a a fragment. The fragment has a listview in it. The list view adapter has two different layouts to show sender's and receivers separately. My listview adapter extends Resource cursor adapter.Everything is working well when the app loads.Now in to the problem the image of the receiver is get replaced by the image of the sender on scrolling the listview. Can some one suggest me a way to overcome this problem? enter image description here

滚动后,列表如下所示

enter image description here

我已经阅读了关于listview视图重新编写的内容,但是坦白说我完全不理解它。

这是listview的消息适配器

我解决了这个问题,因为有两种不同的布局要充气,我必须使用两个不同的视图。
