There are many ways to change the background color of a spinner in Android. The most common is to use the android:background attribute in the XML file of your custom view. You can also set this programmatically by using the setBackgroundColor() method on your Spinner object.
If you want to change the background color of only certain items in the spinner, you can do so by setting a drawable with a tint for each item in the spinner’s adapter.
- Create a new project in Android Studio and name it ChangeSpinnerBackgroundColor
- Open activity_main
- xml file and add the following code:
- 0″ encoding=”utf-8″?>
- We are setting id as textView1 for this textview widget
- Here we have also set paddingLeft = “10dp” , paddingTop= “10dp” , paddingRight= “10dp” & paddingBottom= “10dip” to make some space between border of this widget and its content(country names) so that they will not touch each other while scrolling countries list up or down inside dropdown menu of spinner widget
- style=”?android:listSeparatorTextViewStyle” //This is the style attribute which is used here to separate each country in dropdown menu with a single line separator with grey color by default, if you don’t use this then all countries will display together without any line separator between them like one big string value which looks odd and ugly but not good from UI design perspective
- so we are using it here to look our UI more decent and beautiful with separation lines between each item (countries) in dropdown menu of spinner control android:layout_width=”fill_parent” //setting width as fill parent means taking full width available according whether its a landscape mode or portrait mode device screen orientation because we have set orientation value as vertical i mean in column format so take full height otherwise it will look very bad from UI perspective
- android:layout_height=”wrap_content”/> //Here wrap content means takes only required height means just enough height required for displaying all available countries inside dropdown menu of spinner control without scrollbar because if we use fill parent then extra empty space will be displayed after end of

What is Spinner in Android With Example?
Spinners in Android are like select dropdowns (HTML) of items. They provide a quick way to select one value from a set. In the default state, a spinner shows its currently selected value.
Touching the spinner displays a dropdown menu with all other available values, from which the user can select a new one.
There are two types of spinners:
1) Date format
2) Number format
The android:entries attribute is used to specify an array for the Spinner to use as its data source. This is useful when you want your spinner to have static content that doesn’t change dynamically based on user input or other conditions.
You can also use an ArrayAdapter if you need more control over how the list of choices is displayed, such as specifying a custom layout or providing filtering capabilities.
