Android - Navigation View item menu background color
You don't set the drawable for the background of a Navigation View item in your styles.xml file. Open up your XML layout file containing your Navigation View widget, and add the following line to the widget's attributes:
app:itemBackground="@drawable/activated_background.xml"
If you're having trouble with the "app" pointer, add the following line in as well:
xmlns:app="http://schemas.android.com/apk/res-auto"
Note that this only changes the colour of the background of a selected list item. If you'd like the icon and text colour to change as well, use the app:itemTextColor
attribute instead.
Android Change Navigation View Menu Background
You can set background to your NavigationView
to change its color like below (set to app_white ) & for header set any color as a background of drawer_header_layout.
<android.support.design.widget.NavigationView
android:id="@+id/adcl_navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="@color/app_white"
app:headerLayout="@layout/drawer_header_layout"
app:itemIconTint="@color/app_secondary_text"
app:itemTextColor="@color/app_secondary_text"
app:menu="@menu/menu_drawer"
app:theme="@style/ThemeOverlay.AppCompat.Light" />
Change background color of single specific menu items of navigationView
Change background color of single specific menu items
AFAIK Using menu this is not possible you need to create custom navigationView
When you use BackgroundColorSpan
to set background to your menu item it only set the background to menu item title not whole view
OUTPUT USING
BackgroundColorSpan
Try this way using

OUTPUT
Navigation View seems to alter color of background
In the NavigationView
use the itemShapeFillColor
attribute to fill the item and android:background
for the background of the menu view.
In the layout:
<com.google.android.material.navigation.NavigationView
android:background="#121212"
app:itemShapeFillColor="@color/..."
../>
(I just use an alpha on selected item just to highlight it)
You can also use a style:
<style name="..." parent="Widget.MaterialComponents.NavigationView" >
<item name="itemShapeFillColor">@color/....</item>
</style>
Just a note about the itemBackground
.
In the default style is set to @null
to use a shaped background programmatically generated by NavigationView
when itemShapeAppearance
and/or itemShapeAppearanceOverlay
is set.
This background is styled using the itemShape*
attributes (as itemShapeFillColor
, itemShapeInsetStart
...).
Setting itemBackground
will overwrite the programmatic background and cause values set in the itemShape*
attributes to be ignored.
How to change menu background of android Navigation Drawer
Easiest Way
Create .xml entry in drawable let say nav_checked_item_selector.xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/nav_checked_item" android:state_checked="true"/>
</selector>
create second drawable for checked item background representation let say nav_checked_item.xml
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid android:color="#6633b5e5"/>
</shape>
Now add app:itemBackground="@drawable/nav_checked_item_selector" to your NavigationView Layout.
How to change the Background color of selected item in the Navigation Drawer
I have got the solution-
In the NavigationView I did-
app:itemBackground="@drawable/drawer_selected_item"
Thus my NavigationView looks like-
<android.support.design.widget.NavigationView
android:id="@+id/navigation_view"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="@color/colorPrimary"
app:headerLayout="@layout/header"
app:itemIconTint="@drawable/drawer_item"
app:itemTextAppearance="@style/TextAppearance20"
app:itemTextColor="@drawable/drawer_item"
app:menu="@menu/drawer"
app:itemBackground="@drawable/drawer_selected_item"
tools:context="com.androidexample.newssnips.app.NavigationDrawerFragment" />
In the drawer_selected_item I modified file as-
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_checked="true" android:drawable="@color/colorAccent"/>
<item android:drawable="@android:color/transparent" />
</selector>
Change the color of a checked menu item in a navigation drawer
Well you can achieve this using Color State Resource. If you notice inside your NavigationView
you're using
app:itemIconTint="@color/black"
app:itemTextColor="@color/primary_text"
Here instead of using @color/black
or @color/primary_test
, 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>
Final step would be to change your NavigationView
<android.support.design.widget.NavigationView
android:id="@+id/activity_main_navigationview"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:layout_gravity="start"
app:headerLayout="@layout/drawer_header"
app:itemIconTint="@color/drawer_item" // notice here
app:itemTextColor="@color/drawer_item" // and here
app:itemBackground="@android:color/transparent"// and here for setting the background color to tranparent
app:menu="@menu/menu_drawer">
Like this you can use separate Color State List Resources for IconTint
, ItemTextColor
, ItemBackground
.
Now when you set an item as checked (either in xml
or programmatically), the particular item will have different color than the unchecked ones.
