Add this code to you Functions.php file 


//check if woocommerce plugin is activated
if ( ! function_exists( 'is_woocommerce_activated' ) ) {
function is_woocommerce_activated() {
if ( class_exists( 'woocommerce' ) ) {
return true;
}
else {
return false;
}
}
}


//showing cart header menu item
function andro_cart_menu_item() {
if(is_woocommerce_activated()){
?>

<li class="border"><a class="cart collapsed" data-target=".shopping-bag" href="javascript:;">
<span class="cart-icon"><?php esc_attr_e('Cart','andro');?></span>

<?php
global $woocommerce;
$my_cart_count = $woocommerce->cart->cart_contents_count;

echo '<span class="cart-number-box';
if ($my_cart_count > 0) {
echo ' active';
}
echo '">';echo sprintf( _n('%d', '%d', $woocommerce->cart->cart_contents_count, 'woothemes' ), $woocommerce->cart->cart_contents_count );
echo '</span>';
?>
</a></li>
<?php }
}

function andro_cart_shopping_bag(){
if(is_woocommerce_activated()){
?>
<div class="shopping-bag">
<?php
if ( version_compare( WOOCOMMERCE_VERSION, "2.0.0" ) >= 0 ) {
the_widget( 'WC_Widget_Cart', 'title=' );
} else {
the_widget( 'WooCommerce_Widget_Cart', 'title=' );
} ?>
</div>
<?php
}
}

add_filter( 'add_to_cart_fragments', 'woocommerce_header_add_to_cart_fragment' );

if ( ! function_exists( 'woocommerce_header_add_to_cart_fragment' ) ) {
function woocommerce_header_add_to_cart_fragment( $fragments ) {
global $woocommerce;
ob_start();
?>

<?php
echo '<span class="cart-number-box';
$my_cart_count = $woocommerce->cart->cart_contents_count;
if ($my_cart_count > 0) {
echo ' active';
}
echo '">';
?>
<?php
echo sprintf( _n('%d', '%d', $woocommerce->cart->cart_contents_count, 'woothemes' ), $woocommerce->cart->cart_contents_count );
?></span>


<?php

$fragments['span.cart-number-box'] = ob_get_clean();

return $fragments;
} // End woocommerce_header_add_to_cart_fragment()
}



After that add this code to your header.php 

To show the cart count:
<?php echo sprintf (_n( '%d item', '%d items', $woocommerce->cart->cart_contents_count ), $woocommerce->cart->cart_contents_count ); ?> - <?php echo $woocommerce->cart->get_cart_total(); ?>

or 

<?php if (class_exists('Woocommerce')) {andro_cart_menu_item();} ?>


To show the cart bag or cart Widget: 

<?php  if (class_exists('Woocommerce')) {andro_cart_shopping_bag();} ?>


Sample Header: 

<div class="top-cart">
<div id="cart" class="btn-group btn-block">
<button type="button" data-toggle="dropdown" data-loading-text="Loading..." class="btn btn-inverse btn-block btn-lg dropdown-toggle">
<span class="top-cart-contain">
<span class="title-cart"></span>
<span id="cart-total">

<?php echo sprintf (_n( '%d item', '%d items', $woocommerce->cart->cart_contents_count ), $woocommerce->cart->cart_contents_count ); ?> - <?php echo $woocommerce->cart->get_cart_total(); ?>

<?php if (class_exists('Woocommerce')) {andro_cart_menu_item();} ?>
</span>
<i class="fa fa-caret-down"></i>
</span>
</button>


<ul class="dropdown-menu pull-right">
<li class="arrow-cart"></li>
<li>
<?php  if (class_exists('Woocommerce')) {andro_cart_shopping_bag();} ?>
</li>
</ul>
</div>
</div>
