Select Address from MapActivity and return back to MainActivity

I recently started Android Development, I wanted to create a form by which I also take user address. In the address field I placed a button to choose their location by using map, I successfully get location but the problem is when I return back to main activity all my fields become empty such as name,phone,email e.t.c.

I want that all my fields remain filled after selecting map location

Here is my Main Activity

public class MainActivity extends AppCompatActivity {

    private EditText Name, Phone, Destination;
    private Button mBtnAdd;
    private String type = "1";
    TextView textView;
    LocationManager locationManager;
    String lattitude,longitude;
    private static final int REQUEST_LOCATION = 1;
    private static final String TAG = "MainActivity";


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Name = (EditText) findViewById(R.id.name);
        Phone = (EditText) findViewById(R.id.phone);
        Destination = (EditText) findViewById(R.id.destinationAddress);
        Intent i = getIntent();
        String address = i.getStringExtra ( "address");
        Destination.setText(address);

    }

    private void pickup() {
            Intent intent = new Intent(MainActivity.this, MapsActivity.class);
            intent.putExtra ( "map_type", "1" );
            startActivity(intent);
    }

}

Here Is my select location Function in main Map Activity

public void updateLocation(View view) throws IOException {

        final EditText location = (EditText) findViewById(R.id.name);
        LatLng center = mMap.getCameraPosition().target;
        Log.e(TAG, "Center: " + center);
        Geocoder geocoder;
        List<Address> addresses;
        geocoder = new Geocoder(this, Locale.getDefault());

        addresses = geocoder.getFromLocation(center.latitude, center.longitude, 1); // Here 1 represent max location result to returned, by documents it recommended 1 to 5
        Log.e(TAG, "addresses: " + addresses);
        String address = addresses.get(0).getAddressLine(0);
        Intent i = getIntent();
        Intent intent = new Intent( MapsActivity.this, MainActivity.class );
        intent.putExtra ( "address", address );
        startActivity(intent);

    }
