1. baseLayout 将公共布局提取

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout 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">
    <!--公共头部-->
    <include layout="@layout/include_toolbar_layout_text" />
    <include layout="@layout/include_search_toolbar_layout" />
  <!--刷新组件-->
    <com.scwang.smart.refresh.layout.SmartRefreshLayout
            android:id="@+id/refreshLayout"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:layout_marginTop="@dimen/dp_42">
  <!--刷新头部-->
        <com.scwang.smart.refresh.header.MaterialHeader
                android:layout_width="match_parent"
                android:layout_height="wrap_content" />
        <!--状态组件-->
        <com.xuexiang.xui.widget.statelayout.StatefulLayout
                android:id="@+id/ll_stateful"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                app:stf_animationEnabled="false"
                app:stf_inAnimation="@android:anim/slide_in_left"
                app:stf_outAnimation="@android:anim/slide_out_right">
            <!--列表-->
            <androidx.recyclerview.widget.RecyclerView
                    android:id="@+id/recyclerView"
                    android:background="@color/listBgCol"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent" />
        </com.xuexiang.xui.widget.statelayout.StatefulLayout>

          <!--刷新尾部-->
        <com.scwang.smart.refresh.footer.ClassicsFooter
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:background="@color/split_line" />
    </com.scwang.smart.refresh.layout.SmartRefreshLayout>

</androidx.constraintlayout.widget.ConstraintLayout>

2. 编写 ListBaseActivity

    @Override

    }

                loadData(adapter);
                finishRefresh();
            }
        });
        /**

}

如何使用呢！

1.继承 ListBaseActivity
2.实现上拉下拉监听
3.在initAdapter 方法中返回当前item
4.在loadData 中请求网络数据即可。
