模拟器不断崩溃

为什么我一直得到这个错误：当我点击菜单上的START按钮时，它应该绘制游戏背景，但是仿真器说不确定，APP已经停止。模拟器不断崩溃

这里是logcat的：

这里是PBGame.java。你能帮我解决NullPointerException吗？（PBGame是一个新的活动）

import android.app.Activity; 
import android.os.Bundle; 

public class PBGame extends Activity { 
    final PBGameVars gameEngine = new PBGameVars(); 
    private PBGameView gameView; 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(gameView); 
    } 

    @Override 
    protected void onResume() { 
     super.onResume(); 
     gameView.onResume(); 
    } 

    @Override 
    protected void onPause() { 
     super.onPause(); 
     gameView.onPause(); 
    } 

}

你在PBGame.java的第14行有什么，这行代码给了NPE。 – SathishKumar

错误'PBGame.java：'在第14行。发布'PBGAME.java'代码 –

从documentation，你通常会用一个布局资源定义你UI调用setContentView(int）。

所以，它应该是

setContentView(R.layout.gameView);

，并删除gameView.onResume();和gameView.onPause();

和

gameView = new PBGameView(this);// note the this keyword

好吧，我发现它是一个缺少的行称为：gameView = new PBGameView（this ）;不管怎么说，还是要谢谢你！ – user7777777

如果是这样，你可以回答你的问题。所以它会对别人有帮助 –
