The solutions I found to change the spinner dropdown icon where all:
1. create a custom drawable
For this you can use .9 Patch Image and just simply set it in to background.
android:background="@drawable/spin"
Here i'll give you .9patch image. try with this.
Right click on image and click Save Image as
set image name like this : anyname.9.png and hit save.
Enjoy.. Happy Coading. :)
You need to create custom background like this:
<?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="1dp" android:color="#504a4b"/>
<corners android:radius="5dp"/>
<padding android:bottom="3dp" android:left="3dp" android:right="3dp" android:top="3dp"/>
</shape>
</item>
<item>
<bitmap android:gravity="bottom|right" android:src="@drawable/drop_down"/> // you can place your dropdown image
</item>
</layer-list>
</item>
</selector>
Then create style for spinner like this:
<style name="spinner_style">
<item name="android:background">@drawable/YOURCUSTOMBACKGROUND</item>
<item name="android:layout_marginLeft">5dp</item>
<item name="android:layout_marginRight">5dp</item>
<item name="android:layout_marginBottom">5dp</item>
</style>
after that apply this style to your spinner
Have you tried to define a custom background in xml? decreasing the Spinner background width which is doing your arrow look like that.
Define a layer-list with a rectangle background and your custom arrow icon:
<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
<item>
<shape android:shape="rectangle">
<solid android:color="@color/color_white" />
<corners android:radius="2.5dp" />
</shape>
</item>
<item android:right="64dp">
<bitmap android:gravity="right|center_vertical"
android:src="@drawable/custom_spinner_icon">
</bitmap>
</item>
</layer-list>
