Android diamond key layout

I am currently using Android studio to develop sample applications. I need to design diamond buttons and view them as follows (with screenshots). But I don't know how to do this with Android

There are four diamond buttons, which are aligned according to the following screenshot

This is sample code that adjusts margins based on the device where you can use ImageView instead of buttons

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="match_parent">
    <LinearLayout
        android:id="@+id/firstRow"
        android:rotation="-30"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="30dp"
        android:orientation="horizontal"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
        <Button
            android:layout_width="80dp"
            android:layout_height="80dp"
            android:text="Button 2"
            android:id="@+id/button2" />
        <Button
            android:layout_width="80dp"
            android:layout_height="80dp"
            android:text="Button 1"
            android:id="@+id/button1"/>
    </LinearLayout>

    <LinearLayout
        android:id="@+id/secondRow"
        android:layout_below="@+id/firstRow"
        android:rotation="-30"
        android:layout_marginTop="24dp"
        android:layout_marginLeft="68dp"
        android:orientation="horizontal"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">
        <Button
            android:layout_width="80dp"
            android:layout_height="80dp"
            android:text="Button 4"
            android:id="@+id/button4" />
        <Button
            android:layout_width="80dp"
            android:layout_height="80dp"
            android:text="Button 3"
            android:id="@+id/button3"/>

    </LinearLayout>

</RelativeLayout>
