XRecyclerView的简单使用

请求数据用的是retrofit+Rxjava+MVP框架，这里就不具体写啦！
相信大家都会的哦！下面是XRecyclerView的具体使用：

详解如下：

首先是 MainActivity的布局

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center_horizontal"
    android:orientation="vertical"
    tools:context="com.bwei.lenovo.day0402_xrecylerview.MainActivity">

    <com.jcodecraeer.xrecyclerview.XRecyclerView
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:id="@+id/xrecylerview" />

    <ProgressBar
        android:visibility="gone"
        android:layout_width="50dp"
        android:layout_height="50dp"
        android:id="@+id/pageress"/>

LinearLayout>

然后是在MainActivity中具体写 XRecyclerView，当然前提是要去请求数据的啦！

                //关闭上拉的视图
                xrecylerview.loadMoreComplete();

        });
