碎片中手指向上滑动，加载更多数据问题

[r00_a2lBUR]

我在做一个手指向上滑动，加载更多数据的Demo，数据不用翻页之前，是可以出来，但是数据需要翻页之后，就出不来了，只响应活动向上移动：

碎片的布局：

<?xml version="1.0" encoding="utf-8"?>
<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/ScrollView_All"
    >
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:id="@+id/LinearLayout_All"
        android:orientation="vertical"
        >
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="50dp"
            android:layout_gravity="center_vertical"
            android:text="向上滑动获取更多"
            />
    </LinearLayout>

</ScrollView>

会不会是手机内 存暴涨，很卡，建议清理一下内存

不是内存的原因，是后面不响应onTouch了

上滑加载？？为什么不用recyclerview万能适配器BaseRecyclerViewAdapterHelper https://github.com/CymChad/BaseRecyclerViewAdapterHelper 里面这个列表自带上滑加载的。
