所以基本上当我到达调用精灵的点时，我会在运行游戏时关闭力量。我几乎肯定它与精灵类没有正确编写。如果你不介意的话，我有一个logcat和一些代码来看看。

游戏类代码（被调用的地方，下一个将是实际的生成）

Zombie1 zom1;
private List<Zombie1> normZombie = new ArrayList<Zombie1>();

    private void gamePlay(Canvas canvas) {

        elapsed = System.currentTimeMillis()-startTime;
        canvas.drawRect(0, 0, width, height, clearPaint);


        Rect dst = new Rect(0, 0, width, height);


        canvas.drawBitmap(bmpBackground1, null, dst, null);


         for (Zombie1 zombie1 : normZombie) {
           zombie1.onDraw(canvas);
         }


        zomAttackSound();
        spawnZombie1();

    }


void spawnZombie1(){

       long now = System.currentTimeMillis()-spawnZom1Time;

       if (now > SPAWN_ZOM1_TIME ){
           normZombie.add(createZombie1(R.drawable.zombie1));
           spawnZom1Time = System.currentTimeMillis();

       }
}

这是在Zombie1类中。（我也尝试过下面的游戏）我很确定导致它的东西就在这里......我已经注释掉了很多代码并将其缩小为产生僵尸的东西。

public Zombie1(GameLoopView gameLoopView, Bitmap bmp) {
         this.gameLoopView = gameLoopView;
         this.bmp = bmp;
         this.width = bmp.getWidth() / BMP_COLUMNS;
         this.height = bmp.getHeight() / BMP_ROWS;
         Random rnd = new Random();
         x = rnd.nextInt(gameLoopView.getWidth() - width);

   }

   private void update() {

    if (y > gameLoopView.getHeight() - height - ySpeed-90  || y + ySpeed < 0) {

            game.initGameOver();
            ySpeed=0;

    }
    y = y + ySpeed;
         currentFrame = ++currentFrame % BMP_COLUMNS;
   }

   public void onDraw(Canvas canvas) {
         update();
         int srcX = currentFrame * width;
         int srcY = getAnimationRow() * height;
         Rect src = new Rect(srcX, srcY, srcX + width, srcY + height);
         Rect dst = new Rect(x, y, x + width, y + height);
         canvas.drawBitmap(bmp, src, dst, null);
   }
}

编辑：哦，我忘了把它放进去。这是在spawnzombie1上面的Game类中

private Zombie1 createZombie1(int resouce) {
    Bitmap bmp = BitmapFactory.decodeResource(gameLoopView.getResources(), resouce);
    return new Zombie1(gameLoopView, bmp);
}

在调用尝试生成精灵时强制关闭
