我设置 viewPager.setCurrentItem(3); Fragment切换到了对应的。但是下面的Indicator 没有切换过去。改怎么弄一下嘞？？

可以在AlphaIndicator里面定义一个方法,这个变量是已经定义好的

    /**
     * 添加设置默认第几页的
     * @param currentItem  当前要显示的item
     */
    public void setCurrentItem(int currentItem) {
        this.currentItem = currentItem;
    }

然后在你使用的activity里面，

 viewPager.setCurrentItem(3);
 alphaIndicator.setCurrentItem(3);

同时调用这两个方法，切记，是一起调用，填写的int是一致的。就可以实现
