I want to put black line in between each items of RecyclerView, something like below.

I have got horizontal line in between each row, but not able to find how to get those lines in between columns also.

Check this out: https://bignerdranch.github.io/simple-item-decoration/

Add this to your app level gradle and sync:

compile 'com.bignerdranch.android:simple-item-decoration:1.0.0'

Then, apply code as below:

    Drawable horizontalDivider = ContextCompat.getDrawable(this, R.drawable.line_divider);
    Drawable verticalDivider = ContextCompat.getDrawable(this, R.drawable.line_divider);
    recyclerView.addItemDecoration(new GridDividerItemDecoration(horizontalDivider, verticalDivider, 4));

My line_divider.xml was as follows:

<?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="@android:color/black" />

</shape>

This is just a quick answer from me. But this should work, I guess..

Simply, write your XML file in layout with a RecyclerView In your Activity write the following code to achieve divider for GridLayoutManager in RecyclerView

RecyclerView.LayoutManager mLayoutManager = new GridLayoutManager(getApplicationContext(), 3);
recyclerView.setLayoutManager(mLayoutManager);
recyclerView.setItemAnimator(new DefaultItemAnimator());
DividerItemDecoration Hdivider = new DividerItemDecoration(recyclerView.getContext(), DividerItemDecoration.HORIZONTAL);
DividerItemDecoration Vdivider = new DividerItemDecoration(recyclerView.getContext(), DividerItemDecoration.VERTICAL);
Hdivider.setDrawable(ContextCompat.getDrawable(getBaseContext(), R.drawable.divider));
Vdivider.setDrawable(ContextCompat.getDrawable(getBaseContext(), R.drawable.divider));
recyclerView.addItemDecoration(Hdivider);
recyclerView.addItemDecoration(Vdivider);

Above, both Horizontal and Vertical divider are added to get the whole grid look. The Drawable file can look exactly as you like for your application. Mine looks like this.

   <?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/white" />
    </shape>

Happy Coding!

As per you have four columns I create as per that. This will have three straight vertical line for four columns

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1">
        <View
            android:layout_width="1dp"
            android:layout_height="match_parent"
            android:background="@android:color/transparent"/>
    </RelativeLayout>
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1">
        <View
            android:layout_width="1dp"
            android:layout_height="match_parent"
            android:background="@color/black"/>
    </RelativeLayout>
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1">
        <View
            android:layout_width="1dp"
            android:layout_height="match_parent"
            android:background="@color/black"/>
    </RelativeLayout>
    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1">
        <View
            android:layout_width="1dp"
            android:layout_height="match_parent"
            android:background="@color/black"/>
    </RelativeLayout>
</LinearLayout>
