Android中RecyclerView配合BaseRecyclerViewAdapterHelper实现表格布局(四)

今天介绍了RecyclerView的表格布局,很小的一个功能点,似乎不值得为此写一篇博客,但是想想还是写一篇做个记录。

项目说明:

一,使用的AndroidStudio版本为3.2.1,gradle-4.6

二,使用的RecyclerView的adapter是BaseRecyclerViewAdapterHelper,github上对应的地址如下

github地址为:https://github.com/CymChad/BaseRecyclerViewAdapterHelper
对应的简书说明地址为:https://www.jianshu.com/p/b343fcff51b0

展示效果:

现在正式开始

1,这是RecyclerView的第四篇文章,基本配置如依赖包,下拉刷新功能等在RecyclerView系列(二)中已经说明,不做过多描述。

2,表格布局其实只是看起来是表格,其实还是列表。主activity代码如下,关键是第七步,增加头文件和脚文件。我用红色表示了,看图。

        mTableAdapter.addFooterView(footView);
    }

    /**
     * MainActivity中增加下拉刷新和上拉加载的监听方法
     */
    private void smartRefreshView() {
        srlTable.setOnRefreshLoadMoreListener(new OnRefreshLoadMoreListener() {
            @Override
            public void onRefresh(@NonNull RefreshLayout refreshLayout) {
                //下拉刷新,一般添加调用接口获取数据的方法
                getData(2);

                }
                break;
        }
    }
}

3,头文件布局。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ffffff"
    android:orientation="vertical">

    <View
        android:layout_width="match_parent"
        android:layout_height="0.75dp"
        android:layout_marginLeft="20dp"
        android:layout_marginRight="20dp"
        android:background="#EBEBEB" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="35dp"
        android:layout_gravity="center"
        android:gravity="center"
        android:paddingLeft="20dp"
        android:paddingRight="20dp">

        <View
            android:layout_width="0.75dp"
            android:layout_height="match_parent"
            android:background="@color/tv_eb"></View>

        <TextView
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:gravity="center"
            android:text="小狗"
            android:textColor="@color/colorAccent"
            android:textSize="14sp" />

        <View
            android:layout_width="0.75dp"
            android:layout_height="match_parent"
            android:background="@color/tv_eb"></View>

        <TextView
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:gravity="center"
            android:text="小猫"
            android:textColor="@color/colorAccent"
            android:textSize="14sp" />

        <View
            android:layout_width="0.75dp"
            android:layout_height="match_parent"
            android:background="@color/tv_eb"></View>

        <TextView
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:gravity="center"
            android:text="小兔子"
            android:textColor="@color/colorAccent"
            android:textSize="14sp" />

        <View
            android:layout_width="0.75dp"
            android:layout_height="match_parent"
            android:background="@color/tv_eb"></View>
    </LinearLayout>
</LinearLayout>

4,足文件布局,就一根补全的线。

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#ffffff"
    android:orientation="vertical">

    <View
        android:layout_width="match_parent"
        android:layout_height="0.75dp"
        android:layout_marginLeft="20dp"
        android:layout_marginRight="20dp"
        android:background="@color/colorAccent" />
</LinearLayout>
