Answer 1

You must override onSaveInstanceState (Bundle b) to save your data before loading a new action.

You should also restore the onRestoreInstanceState override and return the values ​​...

You can find more information here:

or

Answer 2

Save the text in editing until the package is provided in the onSaveInsanceState () method . Then in onRestoreInstanceState (), use the values ​​you saved to restore the text in EditTexts.

Answer 3

When returning to the previous step: Use the following method:

 Intent intent_obj=new Intent(); String id = intent_obj.getStringExtra("id"); e1.setText(id); 

It will work .... !!!
