Android 如何获取checked radioButton的值，以便我能够在下一个活动中以复选框形式显示它们？
我正在开发一个测验应用程序，在该应用程序中，用户从每张卡片中选择一个单选按钮（每张卡片包含一个问题，有四个选项），当用户单击floatingActionButton时，用户可以看到他/她在下一个活动中解决了哪些问题。问题编号下方的复选框表示他已解决该问题。 我到处找了，但找不到任何有用的东西。我被困在我的项目中。 这是我的密码 MainActivity.javaAndroid 如何获取checked radioButton的值，以便我能够在下一个活动中以复选框形式显示它们？,android,checkbox,android-recyclerview,Android,Checkbox,Android Recyclerview,我正在开发一个测验应用程序，在该应用程序中，用户从每张卡片中选择一个单选按钮（每张卡片包含一个问题，有四个选项），当用户单击floatingActionButton时，用户可以看到他/她在下一个活动中解决了哪些问题。问题编号下方的复选框表示他已解决该问题。 我到处找了，但找不到任何有用的东西。我被困在我的项目中。 这是我的密码 MainActivity.java package com.pratyush.onlineexamapp; public class MainActivity exten
