How to style the Design Support library's NavigationView?

Question

So I'm using the NavigationView provided by Android Design Support Library

I can't seem to find examples on how to style it.

So far I have:

<android.support.design.widget.NavigationView     android:id="@+id/navigation_view"     android:layout_height="match_parent"     android:layout_width="wrap_content"     android:layout_gravity="start"     app:headerLayout="@layout/header"     app:menu="@menu/drawer"     app:itemTextColor="@color/black"     app:itemIconTint="@color/black"/> 

Styling the header is easy as its under its own xml layout but the body is a menu resource file and not a layout.

• app:itemTextColor changes the text color
• app:itemIconTint changes the icon color
• app:itemBackground changes the item background color

So how to set

• selected item background
• selected item text color
• selected item icon tint

I have answered to a similar question Here.

Basically what you need do is , use a Color State List Resource. For that , first create a new xml (e.g drawer_item.xml) inside color directory (which should be inside res directory.) If you don't have a directory named color already , create one.

Now inside drawer_item.xml do something like this

<?xml version="1.0" encoding="utf-8"?> <selector xmlns:android="http://schemas.android.com/apk/res/android">     <item android:color="checked state color" android:state_checked= "true" />     <item android:color="your default color" /> </selector> 

For itemBackground, a separate drawable needs to be placed inside drawable folder too. The name is same drawer_item. android:drawable property needs to be set instead of android:color for itemBackground:

<selector xmlns:android="http://schemas.android.com/apk/res/android">     <item        android:drawable="@drawable/shape_rectangle_checked"          android:state_checked= "true" />     <item android:drawable="@drawable/shape_rectangle" />  </selector> 

File shape_rectangle:

<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"      android:shape="rectangle"> <solid android:color="#ffffff" /> <!--white color --> </shape> 

File shape_rectangle_checked:

<?xml version="1.0" encoding="utf-8"?> <shape xmlns:android="http://schemas.android.com/apk/res/android"      android:shape="rectangle"> <solid android:color="#25aaf1" /> <!--blue color --> </shape> 

and then set in your navigationview like this

app:itemIconTint="@color/drawer_item" //notice here app:itemTextColor="@color/drawer_item" //and here app:itemBackground="@drawable/drawer_item"//and here for changing the background color of the item which is checked
