Android : ToolBar navigation button

This is my Toolbar:

And this is Gmail app Toolbar:

I want to have the button which open the navigation drawer that the Gmail app has.

How can I achive that?

This is my ToolBar:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/toolbar"
    app:theme="@style/ThemeOverlay.AppCompat.ActionBar"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:minHeight="@dimen/abc_action_bar_default_height_material"
    android:background="#EDAA00" />

This is my theme of the app:

<style name="noActionBar" parent="Theme.AppCompat.Light.NoActionBar"/>

This is my code that create the toolbar:

Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        toolbar.setTitleTextColor(Color.WHITE);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);

Thanks in advance!
