Change Spinner dropdown icon

The solutions I found to change the spinner dropdown icon where all:

1. create a custom drawable

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/vector_drawable_ic_dropdown_black" android:state_focused="true" android:state_pressed="false" />
    <item android:drawable="@drawable/vector_drawable_ic_dropdown_black" android:state_focused="true" android:state_pressed="true" />
    <item android:drawable="@drawable/vector_drawable_ic_dropdown_black" android:state_focused="false" android:state_pressed="true" />
    <item android:drawable="@drawable/vector_drawable_ic_dropdown_black" />
</selector>

2. Set the drawable as the spinner background:

<Spinner
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="16dp"
    android:background="@drawable/custom_spinner_icon"
    android:gravity="center"
    android:paddingBottom="8dp"
    android:paddingTop="8dp"
    android:textColor="@color/textcolorprimary" />

And the result is:

As you can see this is not an acceptable solution since the icon needs to be right aligned and not stretched.

What can i do to make the icon not stretch and align it right?

EDIT

Since there are no working solutions yet i guess i have to specify my question. This is how my Spinner looks using the standard theme:

<Spinner
    android:id="@+id/products_download_spinner_language"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="16dp"
    android:gravity="center"
    android:paddingBottom="8dp"
    android:paddingTop="8dp"
    android:textColor="@color/textcolorprimary"
    android:theme="@android:style/Theme.Holo.Light.DarkActionBar" />

And everything i want (it is really not much i guess) is changing the arrow. i dont want that arrow in the right bottom corner to be displayed, i want this arrow to be displayed vertically centered at the right:

And every solution which i tried until now:

Spinner Dropdown Arrow

How to set dropdown arrow in spinner?

simply werent working. They had stretched icons or the bottom line was missing or something else went totally wrong. I just want another arrow.

Solution 1:

Try applying following style to your spinner using

style="@style/SpinnerTheme"

//Spinner Style:

<style name="SpinnerTheme" parent="android:Widget.Spinner">
    <item name="android:background">@drawable/bg_spinner</item>
</style>

//bg_spinner.xml Replace the arrow_down_gray with your arrow

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

    <item>

        <layer-list>

            <item>
                <shape>
                    <gradient android:angle="90" android:endColor="#ffffff" android:startColor="#ffffff" android:type="linear" />

                    <stroke android:width="0.33dp" android:color="#0fb1fa" />

                    <corners android:radius="0dp" />

                    <padding android:bottom="3dp" android:left="3dp" android:right="3dp" android:top="3dp" />
                </shape>
            </item>

            <item android:right="5dp">

                <bitmap android:gravity="center_vertical|right" android:src="@drawable/arrow_down_gray" />

            </item>

        </layer-list>

    </item>

</selector>

Solution 2:

Add theme to spinner

<Spinner style="@style/SpinnerTheme"
      android:layout_width="match_parent"
      android:layout_height="match_parent"/>

Add spinnerTheme to styles.xml

<style name="SpinnerTheme" parent="android:Widget.Spinner">
    <item name="android:background">@drawable/spinner_background</item>
</style>

Add New -> "Vector Asset" to drawable with e.g. "ic_keyboard_arrow_down_24dp"

Add spinner_background.xml to drawable

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <layer-list>
            <item android:drawable="@drawable/ic_keyboard_arrow_down_24dp" android:gravity="center_vertical|right" android:right="5dp"/>
        </layer-list>
    </item>
</selector>
