In the strings.xml file create a <string-array name="spinner"> tag. create <item> tags inside with each entry. Wrap the text in each item with <![CDATA[ ...raw html... ]]> tag. Put in the formatting information in the raw html part ofcourse.

In the activity,

Spinner spinner = (Spinner) findViewById(R.id.spinner);
    ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
            this, R.array.spinner, android.R.layout.simple_spinner_item);
    adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
    spinner.setAdapter(adapter);

Check the top answer from this post :

Set TextView text from html-formatted string resource in XML

Though this refers to a TextView, it can be modified to be used in a Spinner too.

Your solution is absolutely what i want, Thank you for you help @Samrat Dutta . AND after solving this my application encountered another problem i.e its getting force closed when i change my phones landscape mode from vertical to horizontal or vice-versa. i am using just a EditText component with attributes, android:width="fill_parent & android:height="fill_parent" Do you have any idea over my problem. If you have ay Idea please share here Thank you – John Kiran Jul 18 '15 at 18:48
First of all, you always use match_parent instead of fill_parent. Latest convention. But that is not causing the problem. Although you should use layout_weight="1" instead of android:height="fill_parent". Anyway, I need the Logcat error message when the application crashes to try and solve the issue. – Samrat Dutta Jul 18 '15 at 18:53
Why dont you post your problem as a separate question with the relevant code that you have tried? – Samrat Dutta Jul 18 '15 at 18:54
Because we can post another question only after 90 mins gap – John Kiran Jul 18 '15 at 18:55
Please tell me the logcat error. That will help me understand the problem. – Samrat Dutta Jul 18 '15 at 18:56

It is a nullpointer Exception. The Activity cant find the EditText by id when rotated. It is very hard to answer without the code. If and when possible, do post a question with the code. Try putting `if(savedInstanceState != null) { return; }` inside the `onCreate()` method after `setContentView();` – Samrat Dutta Jul 18 '15 at 19:09
Thank you, You are Genius @Samrat Dutta – John Kiran Jul 18 '15 at 19:32

You'll have to create a custom xml list item for your spinner, something like this list_item_spinner.xml

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

<TextView  
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"
    android:textSize="20sp"
    android:background="#000000"  
    android:textColor="#FB26A9"         
    android:padding="10dip"/>

After that use that file in your code as follows

ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, R.layout.list_item_spinner, mListData);
