问题描述
我有一个应用程序（正在创建中），用户需要及时提交调查（称为MCI或每月签入）。如果签入的完成时间（TOC）在调查日期的AGrade日期之前，则用户会收到100％的信息，8天为85，依此类推（以下为标尺）。
我想显示主活动类中gradingActivity类的用户等级。我有一个Textview来显示名为myUserGrade的内容，其中我将评分设置为评分活动类中从getCompletionDate类收到的getIntExtra的评分。
当前结果/错误-现在，我只有在单击gradingActivity后才能看到用户的等级。当我单击此活动时，只有返回到主活动（或主菜单）后才能看到成绩。此外，我无法继续使用gradingActivity，因为它会立即使我回到主要活动。如果我不单击gradingActivity，则会得到默认值0，并且需要在主要活动中显示成绩。
有人知道为什么只在我单击gradingActivity时才显示成绩，而在我单击评分活动时立即返回主菜单吗？
在创建时在主活动中显示
Intent myIntent = getIntent();
MyGrade = myIntent.getIntExtra("finalMCIGrade1Value",0);
myUserGrade.setText("Your grade is: " + MyGrade);
评分等级-来自gradingActivity类
org.threeten.bp.LocalDate AGrade = MCIAvailable.plusDays(5);
org.threeten.bp.LocalDate BGrade = MCIAvailable.plusDays(8);
org.threeten.bp.LocalDate CGrade = MCIAvailable.plusDays(11);
org.threeten.bp.LocalDate DGrade = MCIAvailable.plusDays(15);
org.threeten.bp.LocalDate FGrade = MCIAvailable.plusDays(20);
