how to have an inline drawable inside layout xml

Issue

I have some drawable resources that are used only in a single xml layout. I would like to insert them into the specific xml layout (inline) so i could have a better organization of my files and a less overloaded drawable folder

i found this topic: https://developer.android.com/guide/topics/resources/complex-xml-resources

but this using an inline drawable as resource for another one... i would like to use it in a layout xml

EXAMPLE:

<?xml version="1.0" encoding="utf-8"?>
<androidx.appcompat.widget.LinearLayoutCompat xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/round_corner"
    android:orientation="horizontal"

    android:padding="@dimen/smallMargin">

    <androidx.appcompat.widget.AppCompatButton
        android:id="@+id/buttonDelete"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:drawableTop="@drawable/code"
        android:text="@string/delete"
 />
</androidx.appcompat.widget.LinearLayoutCompat>

where code.xml is:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:width="@dimen/popupButtonSize"
        android:height="@dimen/popupButtonSize"
        android:drawable="@drawable/ic_population" />

</layer-list>

code is only used in that specific layout, is there any way to make it inline?

Solution

What seems to be the issue? If you follow the guide it works without a problem:

1. Add xmlns:aapt="http://schemas.android.com/aapt" to root node
2. Replace android:drawableTop="@drawable/code" attribute with aapt:attr child

Final XML will look like this:

<?xml version="1.0" encoding="utf-8"?>
<androidx.appcompat.widget.LinearLayoutCompat
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:aapt="http://schemas.android.com/aapt"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/round_corner"
    android:orientation="horizontal"
    android:padding="@dimen/smallMargin">

    <androidx.appcompat.widget.AppCompatButton
        android:id="@+id/buttonDelete"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="bottom"
        android:text="@string/delete">

        <aapt:attr name="android:drawableTop">
            <layer-list xmlns:android="http://schemas.android.com/apk/res/android">

                <item
                    android:width="@dimen/popupButtonSize"
                    android:height="@dimen/popupButtonSize"
                    android:drawable="@drawable/ic_population" />

            </layer-list>
        </aapt:attr>

    </androidx.appcompat.widget.AppCompatButton>
</androidx.appcompat.widget.LinearLayoutCompat>
