How to show xml shape in background at specific place android

Question

I have XML of the light brown circle and I want to place it as background on the top left corner as shown in the pic

Can anyone guide me on how I can do it? I need to show it on multiple screens on different sides. Any hint will be much appreciated

here is the XML of circle

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="oval">
            <solid android:color="@color/light_brown"/>
            <!-- Set the same value for both width and height to get a circular shape -->
            <size android:width="550sp" android:height="550sp"/>
        </shape>
    </item>
</selector>

You can wrap your ImageView in ConstraintLayout and add constraints of:

• app:layout_constraintDimensionRatio="1:1": Making width and height equal (or as proportional as you want)

• app:layout_constraintWidth_percent="0.5": a percentage you need of the Width relative to the parent ConstraintLayout, here I see it half

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

    <ImageView
        android:id="@+id/profile_image_view"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:background="@drawable/quarter"
        app:layout_constraintDimensionRatio="1:1"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintWidth_percent="0.5" />

</androidx.constraintlayout.widget.ConstraintLayout>

You can use the following quarter of a circle drawable instead of a full circle

drawable\quarter.xml

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <size
                android:width="15dp"
                android:height="15dp" />
            <solid android:color="@color/light_brown" />
            <corners android:bottomRightRadius="250dp" />
        </shape>
    </item>
</layer-list>

Result:
