Java 如何在Android应用程序上使用随机点击和计数点击

我正在制作这个应用程序，当你按下喜欢或不喜欢 它将计算数字并保存它。 这并不难，但问题是 我需要随机选择姓名，并分别为每个随机选择的姓名保存喜欢和不喜欢的内容，但每次我按“喜欢”或“不喜欢”随机生成一个新数字，并将喜欢或不喜欢的内容存储在新的随机选择的姓名上

我在下面发布了我所有的代码，对于这个例子，我只有三个名字和数组上的固定数字，这样你就可以自己轻松地检查问题了

很抱歉发了这么长的帖子，但我很绝望

到目前为止，我唯一想到的是一个布尔值，只有当它为真时，它才会使random生成一个新的数字，但我不知道这是否有效，而且我也不知道如何做。
我想提前感谢大家

示例
在create Random上为Second.class中的数组生成索引
假设它生成了1
然后在屏幕上显示在字符串数组中有索引1的名称
吉姆，海伦
然后按是或否
“喜欢”和“不喜欢”按钮出现

---

但当您按“喜欢”或“不喜欢”时，Random会生成一个新数字并在屏幕上显示该数字，但我希望它在屏幕上显示它第一次生成的数字，而不是生成一个新数字

请缩短代码并准确显示您希望在哪一行实现某项目标。您能再次解释一下您希望实现的目标吗？也许举个例子吧？上次我发布了一个简短的代码，有人让我发布整个代码，这样他就可以运行应用程序了，所以我删除了这个帖子并创建了这个。我现在添加一个示例添加一个示例。我没有代表来发布图片，是的，缩短你的代码并准确地显示你想在哪一行实现目标。你能再解释一下你想实现什么吗？也许举个例子吧？上次我发布了一个简短的代码，有人让我发布整个代码，这样他就可以运行应用程序了，所以我删除了这个帖子并创建了这个。我现在添加一个示例添加一个示例。我还没有销售代表发布图片
