You have to store your application state before 'hiding' it - by
overriding onSaveInstanceState() method of your activity and putting
data that must be stored into Bundle passed to the method - and
restore the state when resuming (creating an instance again) - getting
stored info out of Bundle object passed to onCreate() method of the
activity.
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// get out of bundle
String someData = savedInstanceState.getString("userName");
if (someData != null) {
// do something with it
EditText text = (EditText) findViewById(R.id.user_name);
text.setText(someData);
}
...
}
@Override
protected void onSaveInstanceState(Bundle outState) {
// get data from EditText view
EditText text = (EditText) findViewById(R.id.user_name);
// store data
outState.putString("userName", text);
}
Cheers,
