Spinner text size does not change?

Question

I could not change spinner's textsize or colour with the code below:

<Spinner 
    android:id="@+id/spinner1"
    style="@style/submitspinner"
    android:layout_weight="2"
    android:entries="@array/a_code"
    android:prompt="@string/p_code" />

style:

<style name="submitspinner" parent="@android:TextAppearance.Widget.TextView.SpinnerItem">
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">match_parent</item>
    <item name="android:layout_margin">10sp</item> 
    <item name="android:textColor">@android:color/holo_blue_dark</item>
    <item name="android:textSize">@dimen/pt</item> 
</style>

It looks same, how can I increase textsize and change colour of the spinner?

Via XML Only

Just to help others in case they are statically setting their Spinner entries in XML.

The above answers work if you're creating your Spinner via code but if you're setting your Spinner entries via XML, i.e. using android:entries, then you can adjust the text size and other attributes with the following two theme settings:

In your res/values/styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

    <style name="AppBaseTheme" parent="android:Theme.Holo">
    </style>

    <!-- Application theme. -->
    <style name="AppTheme" parent="AppBaseTheme">

        <!-- For the resting Spinner style -->
        <item name="android:spinnerItemStyle">
            @style/spinnerItemStyle
        </item> 

        <!-- For each individual Spinner list item once clicked on -->
        <item name="android:spinnerDropDownItemStyle">
            @style/spinnerDropDownItemStyle
        </item>

    </style>

    <style name="spinnerItemStyle">
        <item name="android:padding">10dp</item>
        <item name="android:textSize">20sp</item>
        <item name="android:textColor">#FFFFFF</item>
    </style>

    <style name="spinnerDropDownItemStyle">
        <item name="android:padding">20dp</item>
        <item name="android:textSize">30sp</item>
        <item name="android:textColor">#FFFFFF</item>
    </style>

</resources>

+1 for addressing styles.xml. I find most developer tend to shoot for a programmatic solution and ignore the less appreciated aspects of the Android framework. — dubmojo, Sep 02 '14 at 16:00
How can I use and apply these styles on my spinner? it doesn't work with me. — Tareq, Sep 03 '14 at 09:50
For AppCompat theme just remove `android:` like this `@style/mySpinnerItemStyle` — Roman_D, Sep 28 '16 at 07:02

What you should do for custom Spinners is create a single XML that will act as your template for the string in the Spinner, like so:

<?xml version="1.0" encoding="UTF-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
   android:id="@+id/standard_spinner_format"
   android:layout_width="wrap_content"
   android:layout_height="wrap_content"
   android:textSize="@dimen/pt"
   android:textColor="@android:color/holo_blue_dark"/>

Then when you create your Spinner adapter in java do the following:

ArrayAdapter<CharSequence> typeAdapter = ArrayAdapter.createFromResource(getActivity(), 
          R.array.my_spinner_array, R.layout.custom_xml_spinner_layout); //change the last argument here to your xml above.
    typeAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);

The OP is using static entries via `android:entries` to populate his Spinner. There's a way to style the Spinners without setting the adapter via code. I added an answer to show how. — Joshua Pinter, Jan 16 '14 at 22:32

customize your spinner

here is a good tutorial i once used

http://stephenpengilley.blogspot.be/2013/01/android-custom-spinner-tutorial.html

it has everything u need.

also in your 'style' u have:

<item name="android:layout_margin">10sp</item>

change it to 10dp

sp = text size

here u can find more about units to measure

What is the difference between "px", "dp", "dip" and "sp" on Android?

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
style="@style/spinnerItemStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="@dimen/margin_5"
android:ellipsize="marquee"
android:layoutDirection="ltr"
android:padding="@dimen/padding_5"
android:singleLine="true"
android:textSize="@dimen/textsize_base" />

 adapter?.setDropDownViewResource(R.layout.spinner_text)
spSourceAccount.adapter = adapter

Spinner text size does not change?
