How Do I Clear Edittext After All Fragments Above It Have Been Popped?

In an Android project, I have 3 fragments, and I navigate through them during an operation the user does. FragmentA -> FragmentB -> FragmentC When the user finishes the ope

Solution 1:

This can be easily done using flags.

The idea is that when the popBackStack() is called, the Activity sets a flag which will be checked by FragmentA in its onResume().

Simplified steps:

1. When popping off FragmentC, do this:

   clearEditTextOfA = true;

2. in onResume() of FragmentA, do this:

   if (activityCallback.shouldClearEditText()) {
       editText.setText("");
   }
   

   The activityCallback is an interface which lets a Fragment communicate with the Activity it is placed in. See Android Docs.

3. Instead of doing ft.add(), do ft.replace().

   This will make the onResume() of your Fragments get called whenever they change.
