I wish this helpful for you Below line making trouble. Because you are adding decoration to your item. This will add divider to your view. Just comment out below line.
recyclerView.addItemDecoration(new DividerItemDecoration(this,  LinearLayoutManager.VERTICAL));

iOS) How to add a divider(==separator) between tabbarItems

I wish did fix the issue. I'm afraid there is no specific option to set a divider in UITabBar. But you can always use a custom tab bar. You can check this out, it has a special property for seperator image:

Android Recycler StaggeredGrid divider

should help you out You just need to override onDraw() to actually paint something on the view. Beware, if adding multiple decorations, the order is important.
Below is some example code drawing a border on the bottom of the view, you will need to draw all 4 borders.
public class DividerDecoration extends RecyclerView.ItemDecoration {

private final Paint mPaint;
private int mHeightDp;


public DividerDecoration(Context context, int color, float heightDp) {
    mPaint = new Paint();
    mPaint.setStyle(Paint.Style.FILL);
    mPaint.setColor(color);
    mHeightDp = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, heightDp, context.getResources().getDisplayMetrics());
}

@Override
public void onDraw(Canvas c, RecyclerView parent, RecyclerView.State state) {
    for (int i = 0; i < parent.getChildCount(); i++) {
        View view = parent.getChildAt(i);
            c.drawRect(view.getLeft(), view.getBottom(), view.getRight(), view.getBottom() + mHeightDp, mPaint);
    }
}

How to hide divider when delete animation happens in recycler view


Tag : android , By : Barry

I wish this help you The solution is fairly easy. To animate a decoration, you can and should use view.getTranslation_() and view.getAlpha(). I wrote a blog post some time ago on this exact issue, you can read it here.
Translation and fading off
// translate
int top = child.getBottom() + params.bottomMargin + view.getTranslationY();
int bottom = top + mDivider.getIntrinsicHeight();

// apply alpha
mDivider.setAlpha((int) child.getAlpha() * 255f);
mDivider.setBounds(left + view.getTranslationX(), top,
        right + view.getTranslationX(), bottom);
mDivider.draw(c);
public class SeparatorDecoration extends RecyclerView.ItemDecoration {

    private final Paint mPaint;
    private final int mAlpha;

    public SeparatorDecoration(@ColorInt int color, float width) {
        mPaint = new Paint();
        mPaint.setColor(color);
        mPaint.setStrokeWidth(width);
        mAlpha = mPaint.getAlpha();
    }

    @Override
    public void getItemOffsets(Rect outRect, View view, RecyclerView parent, RecyclerView.State state) {
        final RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) view.getLayoutParams();

        // we retrieve the position in the list
        final int position = params.getViewAdapterPosition();

        // add space for the separator to the bottom of every view but the last one
        if (position < state.getItemCount()) {
            outRect.set(0, 0, 0, (int) mPaint.getStrokeWidth()); // left, top, right, bottom
        } else {
            outRect.setEmpty(); // 0, 0, 0, 0
        }
    }

    @Override
    public void onDraw(Canvas c, RecyclerView parent, RecyclerView.State state) {
        // a line will draw half its size to top and bottom,
        // hence the offset to place it correctly
        final int offset = (int) (mPaint.getStrokeWidth() / 2);

        // this will iterate over every visible view
        for (int i = 0; i < parent.getChildCount(); i++) {
            final View view = parent.getChildAt(i);
            final RecyclerView.LayoutParams params = (RecyclerView.LayoutParams) view.getLayoutParams();

            // get the position
            final int position = params.getViewAdapterPosition();

            // and finally draw the separator
            if (position < state.getItemCount()) {
                // apply alpha to support animations
                mPaint.setAlpha((int) (view.getAlpha() * mAlpha));

                float positionY = view.getBottom() + offset + view.getTranslationY();
                // do the drawing
                c.drawLine(view.getLeft() + view.getTranslationX(),
                        positionY,
                        view.getRight() + view.getTranslationX(),
                        positionY,
                        mPaint);
            }
        }
    }
}
