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

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);
        }
    }
}

Thanks, works well.
Though getDrawable(int) is deprecated now. Use this instead:

ContextCompat.getDrawable(context, R.drawable.line_divider);

Thank's so much... it's work ....

@jonasbleyl : where is ContextCompat declaration?

ContextCompat is in the support library. ContextCompat.getDrawable(context, resourceID)

Thanks, works great.

thanks

Nice Work!
I've also included the default Android listDivider drawable inside the constructor if you don't want to implement a custom one:

public SimpleDividerItemDecoration(Context context) {
    final TypedArray a = context.obtainStyledAttributes(new int[]{android.R.attr.listDivider});
    mDivider = a.getDrawable(0);
    a.recycle();
}

Thanks.
I used this:

ResourcesCompat.getDrawable(context.getResources(), R.drawable.line_divider, context.getTheme());

I am not able to set divider to my RecyclerView can somebody help me for this?......

ResourcesCompat.getDrawable(context.getResources(), R.drawable.line_divider, context.getTheme());

where should i used this above code?please specify the location

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.
