title: How to pass the values from one activity to previous activity
body: <p>How do I pass a value from one screen to its previous screen?</p>
  
  <p>Consider this case: I have two activities. The first screen has one <code>TextView</code> and a button and the second activity has one <code>EditText</code> and a button. </p>
  
  <p>If I click the first button then it has to move to second activity and here user has to type something in the text box. If he presses the button from the second screen then the values from the text box should move to the first activity and that should be displayed in the first activity <code>TextView</code>.</p>
