Circular button with drawable in the middle

Issue

I'm currently making the layout of an app I'm working on and I'm not able to create this button in xml.

The arrow inside is a .png picture (I can also get it exported as vector) and the background is just a drawable. I am unable to mix this two assets to make this button. My current result is this:

The xml is:

<androidx.appcompat.widget.AppCompatImageView
    android:id="@+id/onboardingStep2NextButton"
    android:layout_width="50dp"
    android:layout_height="50dp"
    app:layout_constraintTop_toBottomOf="@id/onboardingStep2SubTitle"
    android:src="@drawable/long_left"
    android:background="@drawable/purple_round_background"
    app:layout_constraintEnd_toEndOf="parent"/>

purple_round_background.xml

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
    <corners  android:radius="50dp"/>
    <solid android:color="@color/purple" />
</shape>

Thanks for any help

Solution

try to add android:padding may help you:

<androidx.appcompat.widget.AppCompatImageView
    android:id="@+id/onboardingStep2NextButton"
    android:layout_width="50dp"
    android:layout_height="50dp"
    app:layout_constraintTop_toBottomOf="@id/onboardingStep2SubTitle"
    android:src="@drawable/long_left"
    android:background="@drawable/purple_round_background"
    app:layout_constraintEnd_toEndOf="parent"
    android:padding="10dp"
    />
