Solution

Try this

you increase the android:columnCount="2" and android:rowCount="2" in Gridlayout

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <ScrollView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">

        <GridLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:columnCount="2"
            android:orientation="horizontal"
            android:rowCount="2">

            <Button
                android:id="@+id/s"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_column="0"
                android:layout_margin="20dp"
                android:layout_row="0"
                android:background="@mipmap/ic_launcher" />

            <Button
                android:id="@+id/hur"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_column="0"
                android:layout_margin="20dp"
                android:layout_row="1"
                android:background="@mipmap/ic_launcher" />

             <Button
                android:id="@+id/mil"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_column="1"
                android:layout_margin="20dp"
                android:layout_row="0"
                android:background="@mipmap/ic_launcher" />

            <Button
                android:id="@+id/ysr"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_column="1"
                android:layout_margin="20dp"
                android:layout_row="1"
                android:background="@mipmap/ic_launcher" />
