How should I increase the spinner list item font size?

Question

This is my spinner's code:

Spinner food = (Spinner) findViewById(R.id.spinner1); ArrayAdapter<CharSequence> foodadapter = ArrayAdapter.createFromResource(         this, R.array.item_array, android.R.layout.simple_spinner_item); foodadapter.setDropDownViewResource(android.R.layout.simple_spinner_item);         food.setAdapter(foodadapter); 

This is a part of the layout file where I have created the spinner:

<Spinner         android:id="@+id/spinner1"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignParentRight="true"         android:layout_alignParentTop="true"         android:layout_toRightOf="@+id/textView1" /> 

This is the item_array:

<resources>     <string name="item_picker">Select an iten</string>     <string-array name="item_array">         <item>Pizza</item>         <item>Burger</item>         <item>Sandwiches</item>         <item>Bread</item>         <item>Pastries</item>         <item>Snackers</item>     </string-array> </resources> 

Note: I do not want a simple_spinner_dropdown_item.

I just want to increase the size of the list items. How can I do that?

Answer 1

Save the below xml as spinner_layout.xml in layout folder

<?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android"           android:id="@+id/spinnerTarget"           android:layout_width="fill_parent"           android:layout_height="wrap_content"           android:textColor="#000000"           android:textSize="13sp" /> 

change the textSize which you want. and use the below adapter code to fill it.

Spinner food = (Spinner) findViewById(R.id.spinner1); ArrayAdapter<CharSequence> foodadapter = ArrayAdapter.createFromResource(             this, R.array.item_array, R.layout.spinner_layout); foodadapter.setDropDownViewResource(R.layout.spinner_layout); food.setAdapter(foodadapter);

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>
