import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends Activity {
public Button goButton;
public EditText yearField;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
goButton = (Button)findViewById(R.id.goButton);
yearField = (EditText)findViewById(R.id.yearField);
final EnergySource source = new EnergySource();
goButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// Add your code in here!
Intent intent = new Intent(MainActivity.this, TimeTravelActivity.class);
intent.putExtra("EXTRA_YEAR", yearField.getText().toString());
intent.putExtra("EXTRA_ENERGY", source);
startActivity(intent);
}

}
}
import android.os.Bundle;
import android.view.View;
public class TimeTravelActivity extends Activity {
public String targetYear;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_time_travel);
Intent intent = getIntent();
targetYear = intent.getStringExtra("EXTRA_YEAR");
Parcelable p = intent.getParcelableExtra("EXTRA_ENERGY");
EnergySource source = p;
}
}

Parcelable p = intent.getParcelableExtra("EXTRA_ENERGY");
EnergySource source = (EnergySource) p;
