I’m working with tabs in android, according to my requirement I need to open a popup containing 5 tabs. That is, I have a Fragment where I have to open a DialogFragment and this DialogFragment need to show my 5 tabs. So far so quiet! Could enter each content on their respective tabs.
But the problem is that when I change the tab, the values that were entered in another tab are clean. example:
I go into tab1 fills any value in a text field and then when I switch to tab2 tab1 back to the value it had before entered is lost.
Given this scenario, how do I retain the values that were filled to the brim change? Follow the code below to explain further.

Thanks to all who tried to help me!
I do not have much experience with android but from what I saw, the classes must be executed according to the hierarchy proposed by android. That is, in my case I have a main activity which calls the mine fragments and through one of the fragments I had to call a DialogFragment and this would inflate DialogFragment several Views (my tabs), so I have the following structure:
Activity > Fragment > DialogFragment > Views
Based on this solution for my case was thus:
