Why got fatal exception: Error inflating class Spinner

Issue

I would like create my first Spinner.

Work fine, but if I try put the "expand more" arrow, throw an exception.

If I remove item/Bitmap part from gradient_spinner.xml then work fine without error.

layout/activity_settings.xml:

       <LinearLayout
            style="?metaButtonBarStyle"
            android:id="@+id/activity_settings_ll03_hori"
            android:layout_width="fill_parent"
            android:layout_height="fill_parent"
            android:orientation="vertical"
            android:paddingTop="10dp"
            android:layout_marginBottom="10dp"
            android:background="@drawable/button_draw_head_yellow"
            >
            <TextView

AppCompActivity part, where config, the spinner

 val adapter: ArrayAdapter<*> = ArrayAdapter<String>(this, R.layout.activity_store_list, storeList )
        val listSpinner= findViewById<View>(R.id.storeList) as Spinner
        listSpinner.onItemSelectedListener
        listSpinner.adapter = adapter

        listSpinner.setSelection(ItemPosition)
        listSpinner.onItemSelectedListener = this

I read many other stack owerflow thread and try that, but not work for me. For example: Remove bitmap and use item for arrow: This throw exception too: Error inflating class Spinner

<item>

Any idea?

Caused by: android.content.res.Resources$NotFoundException:
File res/drawable/gradient_spinner.xml from drawable resource ID #0x7f07006a

Caused by: org.xmlpull.v1.XmlPullParserException: Binary XML file line #17:
<bitmap> requires a valid 'src' attribute

I'm guessing these are two separate errors.

A <bitmap> resource has to point to a bitmap image, i.e. a .jpg, .gif or .png. You can't use a vector drawable as its src, those aren't bitmaps.

If you want to use a vector drawable instead, you need to use android:drawable instead of android:src. Also your layer-list needs to be the parent element of the drawable:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape android:shape="rectangle">
            <stroke android:width="1dp" android:color="#727c82" />
            <corners android:radius="5dp" />
            <padding android:bottom="3dp" android:left="3dp" android:right="3dp" android:top="3dp" />
        </shape>
    </item>
    <item
        android:drawable="@drawable/ic_expand_more_black_24dp"
        android:tint="@color/colorPrimary"
        android:gravity="bottom|right">
    </item>
</layer-list>

I don't know if that'll fix the not found crash for gradient_spinner.xml, the code you've posted shouldn't compile so it's hard to know, but that should give you some stuff to look at at least
