android在悬浮窗循环显示时间，过一段时间后卡死？

Question

开始的时候开可以，几分钟就出现卡死，不能拖动的现象？

 private FloatViewUtils(Context mContext) {
        this.mContext = mContext;
        manager = (WindowManager) mContext.getSystemService(Context.WINDOW_SERVICE);
        floatView = new FloatView(mContext);

    }

                }
            }
        }
        return instance;
    }
    WindowManager.LayoutParams lp = new WindowManager.LayoutParams();
    public void addFloatView() {

        lp.width = floatView.WIDTH;

        manager.addView(floatView, lp);

        new TimeThread().start();


        floatView.setOnTouchListener(new View.OnTouchListener() {

                    strText = sysTimeStr.toString();
                    floatView.text = strText.toString();
                    break;
