如何在ListView中添加CheckBox

Question

我自定义了一个ListView布局，想在里面添加一个CheckBox按钮，我遇到了下面的第二个问题，虽然有解决方法但不知道具体怎么做，最好能给个完整的例子，谢谢大家了！
1、ListView item中加入checkbox后onListItemClick 事件无法触发。
原因：checkbox的优先级高于ListItem于是屏蔽了ListItem的单击事件。
解决方案：设置checkbox的android:focusable="false"
2、选择其中的checkbox，当滚动ListView的时候，会出现一些Checkbox选择错位的现象，
原因：为记住Checkbox的选择状态
解决方案：当选择Checkbox的时候，记下其状态，然后在getView方法中进行设置

我也写了一个，写得不好，请见谅。
