MainActivity.java

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }
    public void onNav(View v) {
        Intent intent = new Intent(this, Activity2.class);
        startActivity(intent);
    }
}

Activity2.java

public class Activity2 extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_2);
    }
    public void onNavBack(View v) {
        Intent intent = new Intent(this, MainActivity.class);
        startActivity(intent);
    }
}

Expected o/p: if I click button, navigate to activity2, by clicking the btn OK it should set the text to editText. Similarly if I click button2, after clicking OK it should set the text to editText2.

So what is the issue? Have a dig a google? – Piyush Jul 25 '19 at 09:48 — Piyush, Jul 25 '19 at 09:48

In your current Activity, create a new Intent:

String value="Hello world";

    Intent i = new Intent(CurrentActivity.this, NewActivity.class);    
    i.putExtra("key",value);
    startActivity(i);

Then in the new Activity, retrieve those values:

Bundle extras = getIntent().getExtras();
if (extras != null) {
    String value = extras.getString("key");
    //The key argument here must match that used in the other activity
}

Pass data from one activity to another and set to particular EditText field from which it is called
