上篇android 仿iphoneX上滑退出应用动画(二)已经说明将滑动条添加上去了，该篇给该滑动条添加滑动监听。
在添加的时候可以看到这句：
mSlideView.setOnTouchListener(setOnTouchSlideListener);用isGoing和isAnimationBackOver来防止过快点击滑动条造成的程序紊乱，用VelocityTracker获取速度值来判断手指滑动停顿(速度为0)，
AnimatorSet mScreenshotAnimation; ValueAnimator oneAnimation; ValueAnimator twoAnimation ; float mScaleX,mScaleY; ImageView mBackgroundIv,mIv; boolean isOpenRecents = false; long firstTime=0; boolean isAnimationBackOver = true;
