Button to display text from SecondActivity in MainActivity

Question

I have a class MainActivity.java associated with a layout activity_main.xml. In this layout I have a TextView whose id is "textView". I have a second Activity called SecondActivity.java and in this Activity I have a Button. When I click the button, I want to set the text of the TextView in the MainActivity. How can I do this ? The simple:

TextView textView = (TextView) findViewById(R.id.textView);
textView.setText("Some Text");

doesn't seem to work...

start second activity with StartActivityForResult(intent). – Nas Nov 30 '15 at 19:09 — Nas, Nov 30 '15 at 19:09

One Way :

When you click the button use a "SharedPreference" to save an indicator/condition/state.

In onResume of the main activity check the state and update your text.

You can also pass data between activities by adding an "Extra" to the starting intent. – mjstam Nov 30 '15 at 19:12
