Simple RecyclerView Divider

Simple Horizontal Divider Item Decoration for RecyclerView

    mRecyclerView.addItemDecoration(new SimpleDividerItemDecoration(
            getApplicationContext()
    	));

NOTE: Add item decoration prior to setting the adapter

line_divider

<?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="@color/dark_gray" />

</shape>

SimpleDividerItemDecoration.java

public class SimpleDividerItemDecoration extends RecyclerView.ItemDecoration {
    private Drawable mDivider;

    public SimpleDividerItemDecoration(Context context) {
        mDivider = context.getResources().getDrawable(R.drawable.line_divider);
    }

    @Override
    public void onDrawOver(Canvas c, RecyclerView parent, RecyclerView.State state) {
        int left = parent.getPaddingLeft();
        int right = parent.getWidth() - parent.getPaddingRight();

        int childCount = parent.getChildCount();
        for (int i = 0; i < childCount; i++) {
            View child = parent.getChildAt(i);

            RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) child.getLayoutParams();

            int top = child.getBottom() + params.bottomMargin;
            int bottom = top + mDivider.getIntrinsicHeight();

            mDivider.setBounds(left, top, right, bottom);
            mDivider.draw(c);
        }
    }
}

Tried many, but this works like magic.

Thanks

it works
thanks alot

Works perfectly. Thank you

Good

I think custom drawable is not work

Hello,
Maybe use
ContextCompat

public SimpleDividerItemDecoration(Context context) { mDivider = ContextCompat.getDrawable(context, R.drawable.line_divider); }

Thanks a lot

Thanks,It worked!!

how can i made this?

https://developer.android.com/reference/android/support/v7/widget/DividerItemDecoration.html

val linearLayoutManager = LinearLayoutManager(this)
val dividerItemDecoration = DividerItemDecoration(recyclerView.context, linearLayoutManager.orientation)

// Init recyclerView
recyclerView.setHasFixedSize(true)
recyclerView.layoutManager = linearLayoutManager
recyclerView.addItemDecoration(dividerItemDecoration)

Use "card view" for item layout and set "margin top" according to your requirement.
:)

It works beauty... Thanks!

If you don't want the last item to have a divider line after it, simply change for (int i = 0; i < childCount; i++) { to for (int i = 0; i < childCount - 1; i++) { and it will skip the last item divider.
