怎么在启动另外一个Activity

如何在启动另外一个Activity?
我有1个MainActivity,1个SurfaceView,1个 Player类继承activity。


请问要如何在sufaceView里启动并且执行该继承了activity的Player类呢？

我的主要 MainActivity 代码：

Java code

public class MainActivity extends Activity {    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);        requestWindowFeature(Window.FEATURE_NO_TITLE);        setContentView(new MySurfaceView(this));    }

------解决方案--------------------
首先在manifest中注册该activity，然后用显示意图或者隐式意图启动都可以
注册
<activity android:name = ".Player">
跳转
Intent intent = new Intent(this,Player.class);
startActivity(intent);
------解决方案--------------------
public static void open(Activity a, Class<? extends Activity> b,
boolean finishSelf) {
if (b == a.getClass())
return;
Intent intent = new Intent();
intent.setClass(a, b);
a.startActivity(intent);
if (finishSelf) {
a.finish();
a.overridePendingTransition(0, 0);
}
}

把要要跳转的Activity先去注册下，然后调用这个方法！！！
------解决方案--------------------
surfaceView 是画布，不知道，能不能把Activity.画在里面，帮你顶，顶。
------解决方案--------------------
这个不知道，，帮你顶。。
------解决方案--------------------
两种方法:一是xml里定义，事件发生进行跳转
二是动态生成跳转
这是跳转，你的mainActivity会触发onPause事件
------解决方案--------------------
Player为什么要继承activity呢
