Replace fragment clears all Edittext Value

Question

Inside Select Case I used this

getFragmentManager().beginTransaction()
.replace(R.id.frame_entry, new fragment_1())
.addToBackStack(null)
.commit();

to switch between fragments, but I have a problem with it. The fragment contains EditText with a pre-selected values. When I go to fragment_2 and then return to fragment_1 the selected value on my EditText is gone. How can I make the value stay?

getFragmentManager().beginTransaction() .add(R.id.frame_entry, new fragment_1()) .addToBackStack(null) .commit(); — Kintan Patel, Aug 14 '18 at 13:53
Because you are replacing the fragment each time with the new object. — Mahavir Jain, Aug 14 '18 at 13:54

This will probably Fragment Guide help.

Override onSaveInstanceState like this.

 @Override
 public void onSaveInstanceState(Bundle outState) {
 super.onSaveInstanceState(outState);
 outState.putInt("curChoice", mCurCheckPosition);
}

Then you can use it later

 @Override
 public void onActivityCreated(Bundle savedInstanceState) {
 super.onActivityCreated(savedInstanceState);
 if (savedInstanceState != null) {
    // Restore last state for checked position.
    mCurCheckPosition = savedInstanceState.getInt("curChoice", 0);
 }
}

OnActivityCreated is invoked after fragment returns from back stack.

paste the following function in your activity or fragment and whenever you want to switch between fragments call this function – Anubhav Gupta Aug 14 '18 at 14:03

try to save the value of edittext when before fragment transaction occurs and then retrieve when the same fragment is called. – Anubhav Gupta Aug 14 '18 at 14:14
can you guide me on how to do that? maybe a short example – myown email Aug 14 '18 at 14:15
