@Override

    float scale = (position < 0)
            ? ((1 - SCALE_MAX) * position + 1)
            : ((SCALE_MAX - 1) * position + 1);
    float alpha = (position < 0)
            ? ((1 - ALPHA_MAX) * position + 1)
            : ((ALPHA_MAX - 1) * position + 1);
    //为了滑动过程中，page间距不变，这里做了处理
    if (position < 0) {
        ViewCompat.setPivotX(page, page.getWidth());
        ViewCompat.setPivotY(page, page.getHeight() / 2);
    } else {
        ViewCompat.setPivotX(page, 0);
        ViewCompat.setPivotY(page, page.getHeight() / 2);
    }
    ViewCompat.setScaleX(page, scale);
    ViewCompat.setScaleY(page, scale);
    ViewCompat.setAlpha(page, Math.abs(alpha));
