上拉加载更多时，底部不显示加载中了？？

[wwg90]

mRefreshLayout.setDelegate(BgaRefreshActivity.this);
BGARefreshViewHolder refreshViewHolder = new BGANormalRefreshViewHolder(this, true);
mRefreshLayout.setRefreshViewHolder(refreshViewHolder);
refreshViewHolder.setLoadingMoreText("加载中....");

<cn.bingoogolapple.refreshlayout.BGARefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/base_bga_refreshLayout"
android:layout_width="match_parent"
android:layout_height="match_parent">

看了源码，onBGARefreshLayoutBeginLoadingMore在页面里重写的时候必须返回true才行的
