android 仿iphoneX上滑退出应用动画(三)

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)，

其中，该方法是将图片处理为圆角

public static Bitmap getRoundedCornerBitmap(Bitmap bitmap,float roundPx){

Bitmap output = Bitmap.createBitmap(bitmap.getWidth(), bitmap
.getHeight(), Config.ARGB_8888);
Canvas canvas = new Canvas(output);

final int color = 0xff424242;
final Paint paint = new Paint();
final Rect rect = new Rect(0, 0, bitmap.getWidth(), bitmap.getHeight());
final RectF rectF = new RectF(rect);

paint.setAntiAlias(true);
canvas.drawARGB(0, 0, 0, 0);
paint.setColor(color);
canvas.drawRoundRect(rectF, roundPx, roundPx, paint);

paint.setXfermode(new PorterDuffXfermode(PorterDuff.Mode.SRC_IN));
canvas.drawBitmap(bitmap, rect, rect, paint);

return output;
}
