如题，因为ListView中的item是动态加载的，有的比较短，就不容易触发点击事件，这个怎么解决呢？
------解决方案--------------------
设置一下项的宽度为 fill_parent 试试

我在StackOverFlow看到和你一样的问题：android: listview item width fill_parent doesnt work
http://stackoverflow.com/questions/4552977/android-listview-item-width-fill-parent-doesnt-work
解决答案是：
How are you creating your ListView? Is it defined in XML? Are you using a ListActivity? Or are you creating it programmatically? You need to make sure that the ListView itself has a width of fill_parent.
