【RecycleView加分割线】Android RecycleView列表布局添加分割线如此简单

---

效果图

简单起见我还是给出文件的下载地址自己下载一下
文件地址

配置

拷贝类到项目后有一处报红那就是还需要添加分割线的样式文件名字自己取然后把类里的样式名改成你的就O啦

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="line">
    <!-- 显示虚线，破折线的宽度为dashWith，空隙的宽度为dashGap, darkgray -->
    <stroke
        android:width="1px"
        android:color="@color/common_divider_wide"
        android:dashGap="5dp"
        android:dashWidth="5dp" />
    <size android:height="1dp" />
</shape>

使用案例

结合列子体会一下用法吧

主布局

<LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent">
            <android.support.v7.widget.RecyclerView
                android:id="@+id/recycleview"
                android:foregroundGravity="center"
                android:layerType="software"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"/>
        </LinearLayout>
