ListView中显示RatingBar

历尽几个小时的战斗，终于胜利了，listView里面添加了一个RatingBar，但是最后就是没有显示，调来调去，原来是布局文件里面出了问题，问题出在RatingBar显示的位置太小不能显示所以就没有显示出来，我这个布局在RatingBar控件上面还有一个TextView控件，它们是水平排列的，我把TextView里面宽度设置成了android:layout_width="fill_parent"，就没有显示出来，然后改成了android:layout_width="wrap_content"就显示出来了，哎，弄了头天还原是这个原因。。。

下面是自己重写的一个MySimpleAdapter,测试了没有问题
