[移动开发]依赖第三方库SmartRefreshLayout，实现上拉刷新与下拉加载

一、在build.gradle中导入依赖库：
implementation ‘androidx.appcompat:appcompat:1.0.0’ //1.0.0 以上
implementation ‘com.scwang.smart:refresh-layout-kernel:2.0.3’ //核心依赖
implementation ‘com.scwang.smart:refresh-header-classics:2.0.3’ //经典刷新
implementation ‘com.scwang.smart:refresh-footer-classics:2.0.3’ //经典加载

二、布局文件中导入刷新布局框架

<com.scwang.smart.refresh.layout.SmartRefreshLayout
    android:id="@+id/refreshLayout"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="#F1EBEB"
    app:srlAccentColor="@android:color/black"
    app:srlEnablePreviewInEditMode="true"
    app:srlPrimaryColor="#EFEDED"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/search_bar_bottom_divider">
 

   <!--srlEnablePreviewInEditMode 可以开启和关闭预览功能-->

    <com.scwang.smart.refresh.header.ClassicsHeader
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

    <androidx.recyclerview.widget.RecyclerView
        android:id="@+id/list"
        android:name="com.byd.intermap.mvp.main.view.SearchFragment"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="#ffff"
        app:layoutManager="LinearLayoutManager"
        tools:context=".mvp.search.SearchFragment"
        tools:listitem="@layout/search_input_tips_item" />

    <com.scwang.smart.refresh.footer.ClassicsFooter
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</com.scwang.smart.refresh.layout.SmartRefreshLayout>
