Pass Checkbox data from multiple dialogBox to another activity

I'm new with android studio and am not really an expert with programming, hope to get some help.

Now I'm developing a health application where user can click on the 2d image for their symptoms at the red button: 2D image with clickable button dialogBox with checkbox will appear when click on any red button on the image click on button in neck area and other dialog box will appear with list of checkbox. The problem is how do i pass all checkbox status from TwoDActivity.java(that contain the code of the multiple dialog box that contain list of checkbox in different dialog box) to RuleBasedActivity.java(if else condition statement from checkbox tick by user). i have already tried to use intent but it can only pass/saved checkbox data from ONE dialog box. Can i used sharedPreference to pass/saved the checkbox data to RuleBasedActivity? where should i code and how do i code sharedPreference to saved all checkbox data from multiple dialog box to another activity. Thank you in advanced.

TwoDActivity.java

Noted: i'm not fully code all the list of checkbox in dialog box at the head button, shoulder button etc in the 2d image, because now i'm testing to pass/save checkbox data between 3 dialog box to RuleBasedActivity.java.
