How to keep editText inputs when moving from one activity to another?

Question

I have a bunch of EditTexts in one of my activities. They are visible on the screen and the user can type into them. The user can also to move to another, completely different screen. But, currently, if he/she goes back to the activity with the EditTexts, then his/her inputs are no longer shown on the [first] screen.

What code can I use to keep the user inputs in the EditTexts on the first screen/first Activity?

Thanks in advance.

Show the code where you start another activity from `UserDataInputActivity`. — Son Truong, Apr 03 '19 at 03:16
Updated accordingly. It is HUGE, but the processes are essentially logic. Nothing too fancy. I start other activities inside the `onGenericMenuClick` method. — Shounak Ray, Apr 03 '19 at 03:21
Can you show your original code which not merge with first answer? If the answer do not solve your problem, please do not edit your question. — Son Truong, Apr 03 '19 at 03:30
Sorry, the code I updated in the last edit did not "merge with my first answer." It was what I originally had. I have posted my manifest file as well. — Shounak Ray, Apr 03 '19 at 04:35

You can use onSavedInstanceState

@Override
public void onSaveInstanceState(Bundle outState) {
outState.putString("message", "This is my message to be reloaded");
super.onSaveInstanceState(outState);
}

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (savedInstanceState != null) {
    String message = savedInstanceState.getString("message");
    Toast.makeText(this, message, Toast.LENGTH_LONG).show();
}
}

from How to use onSavedInstanceState example please

You need to override onSaveInstanceState(Bundle savedInstanceState) and save your inputs like this

@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
   super.onSaveInstanceState(savedInstanceState);
   savedInstanceState.putString("editTextString", editText.getText().toString());

}

Then you override onRestoreInstanceState(Bundle savedInstanceState) to get saved state

@Override
public void onRestoreInstanceState(Bundle savedInstanceState) {
   super.onRestoreInstanceState(savedInstanceState);
   editText.setText(savedInstanceState.getString("editTextString"), TextView.BufferType.EDITABLE);

}

What does `TextView.BufferType.EDITABLE` mean? I am using EditTexts. — Shounak Ray, Apr 02 '19 at 23:40

Another Way is SharedPreferences, when redirecting another activity store your data in SharedPreferences as blow

SharedPreferences sharedpreferences;
sharedpreferences = getSharedPreferences(MyPREFERENCES, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = sharedpreferences.edit();

editor.putString("Agestr","3");
editor.putString("Speedstr", "22");

editor.commit();

When you come back on this screen get this data from SharedPreferences and fill your edit text

String Agestr = prefs.getString("Agestr", ""); 
((EditText) findViewById(R.id.AgePromptValue)).setText(Agestr )

Where do I put the code for the shared preferences? Inside `onCreate` or maybe some other method? – Shounak Ray Apr 03 '19 at 07:02
when you call the next activity. after when you come back that time get data in Oncreate method – Haresh Ramani Apr 03 '19 at 09:41
