SurfaceView 中 触发OnTouch 事件时图片绘制异常，怎么解决

Question

1. • 1. public class PaintGameView extends SurfaceView implements Runnable, SurfaceHolder.Callback, View.OnTouchListener { Config config = new Config(); private SurfaceHolder holder; private Bitmap lsecCache; private ArrayList gameImages = new ArrayList<>(); private ArrayList bullets = new ArrayList<>(); private ArrayList enemys = new ArrayList<>(); private Boolean runState = false; private Context context; private Hero selectedPlane; public PaintGameView(Context context, Config config){ super(context); this.context = context; getHolder().addCallback(this); setOnTouchListener(this); } private void init(){ new importInit(config); enemys = importInit.getsBitmap("enemy"); gameImages.add(new BackgroundImage(config)); gameImages.add(new Enemy(config, enemys)); gameImages.add(new Hero(config)); lsecCache = Bitmap.createBitmap(config.getWidth(), config.getHeight(), Bitmap.Config.ARGB_8888); }

   @Override

   Canvas canvas;
   try {
   while (runState){

           //描绘子弹部分
           if(selectedPlane != null){
               if(timeBullet++ == 4){
                   bullets.add(new Bullet(config, selectedPlane, bullets));
                   timeBullet = 0;
               }
           }
          canvas = new Canvas(lsecCache);
   
           //默认描绘
           for(GameViews gameImage : (ArrayList<GameViews>)gameImages.clone()){

   }else {
   selectedPlane = null;
   }
   break;
   }
   }

   }else if(event.getAction() == MotionEvent.ACTION_MOVE){
       if(selectedPlane != null){
           selectedPlane.setX((int) event.getX() - selectedPlane.getBitmap().getWidth()/2);
           selectedPlane.setY((int) event.getY() -  selectedPlane.getBitmap().getHeight()/2);
       }
   }else if(event.getAction() == MotionEvent.ACTION_UP){
       selectedPlane = null;
   }
   return true;
   

   }
   }

发射子弹时，敌机加速了，是onTouch引发的，查过不是参数配置引起的，求解决
