To show the data from main activity in the second, you have to pass it as intent extra.

MainActivity

Intent i = new Intent(this, SecondActivity.class);
i.putExtra(EXTRA1_TEXT, "This value one for ActivityTwo ");
i.putExtra(EXTRA2_TEXT, "This value two ActivityTwo");

SecondActivity

Bundle extras = getIntent().getExtras();
if (extras == null) {
  return;
}
// get data via the key
String value1 = extras.getString(Intent.EXTRA1_TEXT);
if (value1 != null) {
  // do something with the data
}

To communicate between activities you could use:

  1. Custom intents
  2. Events
  3. Broadcasts
