you can use ItemDecoration

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

https://gist.github.com/lapastillaroja/858caf1a82791b6c1a36

Refer Here

sample

int numColumns = 2;

Drawable horizontalDivider = ContextCompat.getDrawable(this, R.drawable.divider_horizontal);
Drawable verticalDivider = ContextCompat.getDrawable(this, R.drawable.divider_vertical);

recyclerView.setLayoutManager(new GridLayoutManager(..., numColumns));

recyclerView.addItemDecoration(new GridDividerItemDecoration(horizontalDivider, verticalDivider, numColumns));

Horizontal:divider_horizontal.xml

<View
    android:layout_width="fill_parent"
    android:layout_height="1dp"
    android:background="#FF0000" />

Vertical:divider_vertical.xml

<View
    android:layout_width="1dp"
    android:layout_height="fill_parent"
    android:background="#FF0000" />
