推荐答案
如果你还没有，你需要编写自定义ListAdapter，
http://developer.android.com/reference/android/widget/ListAdapter.html
if you have not, you need to write a custom ListAdapter, http://developer.android.com/reference/android/widget/ListAdapter.html
您将通过扩大BaseAdapter开始，
http://developer.android.com/reference/android/widget/BaseAdapter.html
you will start by extending BaseAdapter, http://developer.android.com/reference/android/widget/BaseAdapter.html
和最终覆盖getView（）。这就是你将构建您的自定义视图。在XML定义它，它充气，并设置在左边的图像视图到任何你想要基于这一立场支持视图的模型元素的状态。
and will ultimately override getView(). that's where you will construct your custom view. define it in XML, inflate it, and set the image view on the left to whatever you want based on the state of the model element for that position backing the view.
创建一个自定义列表适配器的细节超出了什么，我可以写在这里的范围，但如果你在谷歌它可以，你可以找到很多很好的例子。这里有一个，涵盖了基础知识，

the details of creating a custom list adapter are beyond the scope of what i can write here, but if you google on it can you can find lots of good example. here's one that covers the basics, http://androidcookbook.com/Recipe.seam;jsessionid=5424397F3130CE7769FF47DD67742911?recipeId=588&recipeFrom=ViewTOC
