我试图将复选框和数据从android studio中的多个活动传递到一个活动，即使用RuleBasedActivity.java的SharedPreferences。
然后在RuleBasedActivity中，我使用if else语句在另一个活动中显示结果，该活动基于用户的复选框打勾而在HeartDiseaseResult.java中。
在RuleBasedActivity中，我尝试编写一个简单的if else条件测试，以成功显示结果。结果应该是心脏病的低风险可能性，高风险，可能性很小或其他。
例如，如果用户勾选复选框leftArm || bothArms，则应显示“心脏病风险高”为真，如果用户勾选复选框NoneOther || radioMale || sweating || jaw，则应显示“心脏病风险低”为真，但不幸的是，它显示所有4个结果。
请，希望在这里得到一些帮助。

最佳答案
在任何情况下都不能将它们设置为false，这就是为什么所有if块都被执行的原因。默认情况下，将这些值初始化为false，然后根据情况设置为true。
highRiskOfHeartDisease = true;
lowRiskOfHeartDisease = true;
unlikelyNoHeartDisease = true;
other = true
