DividerItemDecoration will not work no matter what I do

Question

This is the code for setting the decoration :-

recyclerView.addItemDecoration(new DividerItemDecoration(recyclerView.getContext(), DividerItemDecoration.HORIZONTAL));

This is the xml :-

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
    <size android:height="1dp" />
    <solid android:color="@android:color/black" />
</shape>

I have tried setting the drawable using DividerItemDecoration.setDrawable(Drawable drawable) and setting the android:listDivider item in my theme to point to the xml.

I have also tried setting the width to 1dp. Absolutely nothing works.

Any help is appreciated, thanks.

don't use "recyclerView.getContext()". if you have activity then use "ActivityName.this" as context and if you use Fragment then use "getContext" as context. — Prayag Gediya, Feb 19 '19 at 13:26
What is the orientation of your RecyclerView? I would try passing in the orientation of the RecyclerView when you set your divider. — Bilal Naeem, Feb 19 '19 at 14:05
Use LinearLayout.HORIZONTAL or RelativeLayout.HORIZOTAL which you use as root node in your xml file instead of DividerItemDecoration.HORIZONTAL — Prayag Gediya, Feb 19 '19 at 14:08
android:listDivider is used for ListView, it's not suitable for RecycleView — Stanislav Shamilov, Feb 19 '19 at 14:14

If the orientation of your RecyclerView is default(vertical), then you should use DividerItemDecoration.VERTICAL instead.

I've just tried creating a RecyclerView with a default DividerItemDecoration and your xml resource, and everything worked

That did it! I mistook the orientation parameter to be the orientation I want the line to be and not the RecyclerView orientation as it should be. Thanks a ton :) – Mihir Kandoi Feb 19 '19 at 15:16
