Android RecyclerView suggest change

Add divider lines to RecyclerView items

Just add these lines to the initialization

RecyclerView mRecyclerView = (RecyclerView) view.findViewById(recyclerView);
mRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
mRecyclerView.addItemDecoration(new DividerItemDecoration(getActivity(), DividerItemDecoration.VERTICAL));

Add an adapter and call .notifyDataSetChanged(); as usual ! This is not an inbuilt feature of Recyclerview but added in the support libraries. So don’t forget to include this in your app level build.gradle file

compile "com.android.support:appcompat-v7:25.3.1"
compile "com.android.support:recyclerview-v7:25.3.1"
Multiple ItemDecorations can be added to a single RecyclerView.

Changing divider color :

It’s pretty easy to set an color for a itemDecoration.

  1. step is: creating a divider.xml file which is located on drawable folder
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
       android:shape="line">
    <size
        android:width="1px"
        android:height="1px"/>
    <solid android:color="@color/divider_color"/>
</shape>
  1. step is: setting drawable
// Get drawable object
Drawable mDivider = ContextCompat.getDrawable(m_jContext, R.drawable.divider);
// Create a DividerItemDecoration whose orientation is Horizontal
DividerItemDecoration hItemDecoration = new DividerItemDecoration(m_jContext,
        DividerItemDecoration.HORIZONTAL);
// Set the drawable on it
hItemDecoration.setDrawable(mDivider);
// Create a DividerItemDecoration whose orientation is vertical
DividerItemDecoration vItemDecoration = new DividerItemDecoration(m_jContext,
        DividerItemDecoration.VERTICAL);
// Set the drawable on it
vItemDecoration.setDrawable(mDivider);
