I have a main activity with 2 fragments. One of the fragments is a form. After submitting the form, a new results activity is a launched which has a back navigation button. When I press this back button, I am taken back to the form, but my form is cleared. I want to retain all the data which I entered initially before submitting. How can I achieve this?

My fragments are in main activity and the problem happens when I navigate back to it from the search result activity. I am not switching from one fragment to another – Deepa Sreekumar Nov 18 '18 at 10:45

You have to remember about active / fragment lifecycle. When you back to your activity / fragment you have to refresh method @onResume. So if you forgot about @onResume method you have to implement overridden and put there your missing methods.

It is retaining the values when I press the hardware back button, but not the soft button in the app – Deepa Sreekumar Nov 18 '18 at 10:32

I was able to solve the issue by setting the launchMode of the activity that held the fragments as singleTop in the manifest file.
android:launchMode="singleTop"
