Android RatingBar实现五星好评

属性

isIndicatorRatingBar 是否为指示器，为true时，用户将无法交互操作，默认为false。

numStars 显示的星型数量，必须是一个整形值，像“50”，虽然可以设置很大，但一般都是5-10个星星即可。

rating 设置默认的评分。

stepSize 评分每次增加的值。建议大于0小于等于1之间最合适。

样式

其中内置了三个样式：

style="?attr/ratingBarStyle"：默认样式

style="?android:attr/ratingBarStyleSmall"：小样式

style="?android:attr/ratingBarStyleIndicator"：指示器样式

dialog弹框显示好评操作效果图
