请教各位前辈，老师布置的一个Android游戏项目，用的工具是eclipse编译。网上找了一个拼图游戏，它没有游戏菜单界面，我想自己添加一个menu界面，布局文件和逻辑代码简单写了下，运行后，从菜单点击进入游戏，可以进入到原来的游戏界面，但是按键无反应，游戏倒计时也无反应（如图）。
到底是缺少了啥语句导致的啊？
**如下为菜单代码：**
package hbsi.game.main;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainMenuView extends Activity implements OnClickListener{
private Button startBtn;
private Button exitBtn;
MainActivity mainActivity = new MainActivity();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.start_menu);
startBtn = (Button)findViewById(R.id.startBtn);
exitBtn = (Button)findViewById(R.id.exitBtn);
startBtn.setOnClickListener(this);
exitBtn.setOnClickListener(this);
}
@Override
public void onClick(View v) {
if(v.getId() == startBtn.getId())
{
setContentView(R.layout.activity_main);
//Intent itent=new Intent();
//itent.setClass(MainMenuView.this, MainActivity.class);
//startActivity(itent);
//MainMenuView.this.finish();
}
if(v.getId() == exitBtn.getId())
{
}
}
}
如下为游戏界面逻辑代码：
