private void changeToolbarAlpha() {
  int scrollY = mScrollView.getScrollY();
  //快速下拉会引起瞬间scrollY<0
  if (scrollY < 0) {
    toolbar.getBackground().mutate().setAlpha(0);
    return;
  }
  //计算当前透明度比率
  float radio = Math.min(1, scrollY / (mBanner.getHeight() - toolbar.getHeight() * 1f));
  //设置透明度
  toolbar.getBackground().mutate().setAlpha((int) (radio * 0xFF));
}

private void TitleAlphaChange(int dy, float mHeaderHeight_px) {//设置标题栏透明度变化
  float percent = (float) Math.abs(dy) / Math.abs(mHeaderHeight_px);
  //如果是设置背景透明度，则传入的参数是int类型，取值范围0-255
  //如果是设置控件透明度，传入的参数是float类型，取值范围0.0-1.0
  //这里我们是设置背景透明度就好，因为设置控件透明度的话，返回ICON等也会变成透明的。
  //alpha 值越小越透明
  int alpha = (int) (percent * 255);
  toolbar.getBackground().setAlpha(alpha);//设置控件背景的透明度，传入int类型的参数（范围0~255）
  ivBack.getBackground().setAlpha(255 - alpha);
  ivMore.getBackground().setAlpha(255 - alpha);
