I would like to add a Button to the scene, but I don't know how to. Can anybody give me some lights?
UPDATE: Here is my Activity :
public class MyActivity extends Activity {
private GameEngineView gameEngine;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// add Game Engine
gameEngine = new GameEngineView(this);
setContentView(gameEngine);
gameEngine.requestFocus();
}
}
