我的所有三个评分都在每三个 TextView 中返回相同的值，而不是在自己的 TextView 中返回每个评分值

问题描述

我有一个使用意图的主要活动和对话。我试图将三个评级栏对话框中的值返回到 MainActiviy，每个都显示在 Textview 中。一切正常。我的问题是，即使我为每个评级栏选择了三个不同的评级，也只有评级栏的一个 VALUE 被返回到 Textviews。在三个文本视图中的每一个中显示相同的值，而不是在自己的文本视图中单独显示每个 ratingbars 值。

示例： ratingBar1 评分：2.0 ratingBar2 评分：4.0 ratingBar3 评分：3.0

MainActivity 显示： 文本视图 1：2.0 文本视图2：2.0 文本视图3：2.0

它应该显示：

MainActivity 显示： 文本视图 1：2.0 文本视图2：4.0 文本视图3：3.0
