我想在RecyclerView的每个项目之间插入黑线，如下所示.

I want to put black line in between each items of RecyclerView, something like below.

我在每行之间都有一条水平线，但也找不到如何在各列之间获得这些线.

I have got horizontal line in between each row, but not able to find how to get those lines in between columns also.

chintan soni的答案效果很好，但是当我有5个视图时，它仅在一种情况下产生了问题，它还显示了其他3个项目的分隔线，如下所示:

推荐答案

检查一下: https ://bignerdranch.github.io/simple-item-decoration/

将此添加到您的应用程序级别gradle并同步:

Add this to your app level gradle and sync:

compile 'com.bignerdranch.android:simple-item-decoration:1.0.0'

然后，应用以下代码:

    Drawable horizontalDivider = ContextCompat.getDrawable(this, R.drawable.line_divider);
    Drawable verticalDivider = ContextCompat.getDrawable(this, R.drawable.line_divider);
    recyclerView.addItemDecoration(new GridDividerItemDecoration(horizontalDivider, verticalDivider, 4));

我的line_divider.xml如下:

My line_divider.xml was as follows:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">

    <size
        android:width="1dp"
        android:height="1dp" />

    <solid android:color="@android:color/black" />

</shape>

这只是我的一个快速答案.但这应该可行，我猜..

This is just a quick answer from me. But this should work, I guess..
