Restore the edit text value entered

Question

The value is entered in edit text in Activity A. When going to another activity B without saving and coming back A , the value of form in edit text in Activity A gets cleared. How can the edit text value gets restored?

 @Override
protected void onSaveInstanceState(Bundle outState) {

    outState.putString("company", company.getText().toString());
    outState.putString("name", name.getText().toString());
    outState.putString("email",email.getText().toString());
    outState.putString("phone",phone.getText().toString());
    outState.putString("address",address.getText().toString());
    outState.putString("desc",desc.getText().toString());
    super.onSaveInstanceState(outState);
}
@Override
protected void onRestoreInstanceState(Bundle savedInstanceState) {
    super.onRestoreInstanceState(savedInstanceState);
     co = savedInstanceState.getString("comoany");
     em = savedInstanceState.getString("email");
     ph = savedInstanceState.getString("phone");
     add = savedInstanceState.getString("address");
     na = savedInstanceState.getString("name");
     de = savedInstanceState.getString("desc");
}

@Override
protected void onResume() {

    Log.i("this", "Company::::::::::::" + co);
    company.setText(co);
    super.onResume();
}

Use save instance state or shared preferences to save the value and populate it in onResume — Ashish Kumar, Jul 13 '18 at 09:37

use shared preference to store values of edit text and try to fetch the data from shared preference if present when activity opens — Shubham Agarwal Bhewanewala, Jul 13 '18 at 09:55
if you check the spelling of your company is wrong try correcting the typo. your key is company but in youronRestore you are calling comoany — Austine Gwa, Jul 13 '18 at 10:18

This is not default behavior of Android.

Activity A will retain values until it is finished (destroyed). Check if you are not calling finish() after startActivity().

Some solutions can be.

Store your EditText value in SharedPreference.
Save state of EditText value

what you need is to override onSaveInstanceState in your activity A and store the value of your edit text as follows:

 @Override
public void onSaveInstanceState(Bundle outState) {

outState.putString(TEXT_VIEW_KEY, mTextView.getText());

// call superclass to save any view hierarchy
super.onSaveInstanceState(outState);

}

and in your onCreate activity should now check if there is any data that was previously saved and then initialize your textview

@Override
public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

// recovering the instance state
if (savedInstanceState != null) {
    String text  = savedInstanceState.getString(TEXT_VIEW_KEY,);
}


setContentView(R.layout.main_activity);

// initialize member TextView so we can manipulate it later
mTextView = (TextView) findViewById(R.id.text_view);
mTextView.setText(text);

}
