Set layout in landscape:

<activity
    android:name="YourActivity"
    android:screenOrientation="landscape">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

AbsoluteLayout is deprecated, you should’t use this and if you want to move button you can use margin as:

    <Button
        android:id="@+id/btn16"
        ...
        android:layout_marginTop="10dp"
        android:layout_marginStart="10dp"/>

instead of:

    <Button
        android:id="@+id/btn16"
        ...
        tools:layout_x="10dp"
        tools:layout_y="10dp"/>
