Magento custom extension not showing layout template

Question

This is my controller

<?php 
class Karmick_Refer_IndexController extends Mage_Core_Controller_Front_Action{
    public function indexAction()
    {
        $this->loadLayout();
        $this->getLayout()->getBlock('head')->setTitle($this->__('Earn Money'));
         $this->renderLayout();
    }
    public function getCodeAction(){
        $this->loadLayout();

         $this->renderLayout();

    }
    public function checkAction(){
        die('Hello');
    }

}
?>

This is my layout xml file code

<?xml version="1.0"?>
<layout version="0.0.1">
<default>
    <remove name="left"/>
<reference name="head">
    <action method="addItem"><type>skin_css</type><name>css/karmick/check.css</name></action>
</reference>
<reference name="root">
            <action method="setTemplate"><template>page/2columns-right.phtml</template></action>
</reference>
</default>
<refer_index_index>
    <reference name="content">
        <block type="refer/refer" name="refer">
            <action method="setTemplate">
               <template>karmick/refer.phtml</template>
            </action>
        </block>
</reference>
</refer_index_index>
</layout>

This is my config.xml

<?xml version="1.0"?>
<config>
    <modules>
        <Karmick_Refer>
            <version>0.0.1</version>

Answer 1

change refer_index_index to karmick_refer_index_index.

In config.xml you have define karmick_referas your frontname identifier for this extension.

  <routers>
            <karmick_refer> <!  frontName Identifier -->
                <use>standard</use>
                <args>
                    <module>Karmick_Refer</module>
                    <frontName>refer</frontName>
                </args>
            </karmick_refer>
        </routers>

Also whenevr a page layout load then a unique handle are created which are same as below format

'FrontNamaIdentifier_ControllerName_ActionName' .

So for your case it is karmick_refer_index_index.

Answer 2

Use this code in your layout xml:

<refer_index_index>   
    <reference name="content">   
      <block type="refer/refer" name="refer" template="karmick/refer.phtml"/>   
    </reference>   
  </refer_index_index> 

Answer 3

You need to change

<refer_index_index>
    <reference name="content">
        <block type="refer/refer" name="refer" template="karmick/refer.phtml" />
    </reference>
</refer_index_index>

Add bellow code in config.xml file

        </Karmick_Refer>
    </modules>             
    <frontend>
        <routers>
            <refer>
                <use>standard</use>
                <args>
                    <module>Karmick_Refer</module>
                    <frontName>refer</frontName>
