如题，代码中用到了ListView并用到了一个简单的SimpleAdapter来适配其中的List。
其中在调试的时候会遇到弹错，log如下

[in ListView(2131361805, class android.widget.ListView) with Adapter(class com.roadrover.xxx.xxx 可见应该是我们在操作Adapter的时候有误，要么是多线程的时候在后台非UI线程处理了Adapter而没有更新ListView，要么是UI线程里更新了Adapter而没更新ListView。总之是更新Adapter和更新ListView没有匹配出现，于是仔细找了下确实发现了调用了数据集的clear操作，，后面没有跟着调用adapter.notifyDataSetChanged()。都检查完后，继续调试，一切正常。
别人失去了信心，他却下决心实现自己的目标。
