android在listview中使用Ratingbar所需的示例

概述我正在学习android,想要一个示例代码或使用Ratingbar的示例仅用于显示评级,并且列表视图中没有onclick事件.我正在使用json从mysql数据库中获取数据.转换为浮动格式后,相同的数据必须显示在列表中的评级栏中.我在这里尝试了许多关于stackoverflow的示例,但其中大多数似乎都不完整.

我正在学习android,想要一个示例代码或使用ratingbar的示例仅用于显示评级,并且列表视图中没有onclick事件.

我正在使用Json从MysqL数据库中获取数据.转换为浮动格式后,相同的数据必须显示在列表中的评级栏中.我在这里尝试了许多关于stackoverflow的示例,但其中大多数似乎都不完整.

谢谢

以下是代码m用于在列表中显示字符串值的代码
