Navigation Drawer Item Background Colour for Selected Item

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>

Navigation Drawer item background colour for selected item

Still not sure why it is that it doesn't work. But the way I found around it is to use my own simple_list_item_activated layout to be passed to the ArrayAdapter which was basically the same except for setting the text colour to white. I then replaced getActionBar().getThemedContext() with getActivity().getBaseContext() and it now has an effect.

This may not be the correct way and may have repercussions in the future, but for now I have it working the way I want it to.

Navigation Drawer item divider with selected background color

I got it. It was a simple issue. I was just using the wrong state. So, here's the solution. I created two different layer lists (to add the divider to the navigation items):

nav_divider:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:left="@dimen/activity_horizontal_margin">
        <shape android:shape="rectangle">
            <solid android:color="@color/light_gray"/>
        </shape>
    </item>
    <item android:bottom="1dp">
        <shape android:shape="rectangle">
            <solid android:color="@color/white"/>
        </shape>
    </item>
</layer-list>

nav_divider_selected:

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:left="@dimen/activity_horizontal_margin">
        <shape android:shape="rectangle">
            <solid android:color="@color/light_gray"/>
        </shape>
    </item>
    <item android:bottom="1dp">
        <shape android:shape="rectangle">
            <solid android:color="@color/light_blue"/>
        </shape>
    </item>
</layer-list>

Then, created a drawer_item_background drawable like this (state_checked should be used not state_selected):

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

And, then I used this drawable as itemBackground in my NavigationView:

<com.google.android.material.navigation.NavigationView
    android:id="@+id/nav_view"
    android:layout_width="wrap_content"
    android:layout_height="match_parent"
    android:layout_gravity="right"
    android:fitsSystemWindows="true"
    android:background="@color/white"
    app:headerLayout="@layout/nav_header"
    app:menu="@menu/drawer_menu"
    app:itemTextColor="@color/drawer_item"
    app:itemIconTint="@color/drawer_item"
    app:itemBackground="@drawable/drawer_item_background"/>

Navigation Drawer selected item not showing background color for second group of items

Change your @string/navigation_second_group_title item block to

<item android:title="@string/navigation_second_group_title">
    <menu>
        <group android:checkableBehavior="single">
            <item
                android:id="@+id/nav_settings"
                android:icon="@drawable/ic_menu_settings"
                android:title="@string/nav_item_settings" />
            <item
                android:id="@+id/nav_about"
                android:icon="@drawable/ic_menu_about"
                android:title="@string/nav_item_about" />
            <item
                android:id="@+id/nav_help"
                android:icon="@drawable/ic_menu_help"
                android:title="@string/nav_item_help" />
        </group>
    </menu>
</item>

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.

How to change the colour of the navigation drawer item

I solved it setting this attribute to my NavigationView app:itemBackground="@drawable/drawer_selector"

and my drawer_selector is as below

<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_pressed="true" android:drawable="@color/white" />
<item android:state_focused="true" android:drawable="@color/white" />
<item android:state_activated="true" android:drawable="@color/white" />
<item android:drawable="@color/orange" />

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 RecyclerView

activity_main.xml

OUTPUT

NavigationView(Change Color of Selected Item)

create a selector

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

and set

app:itemBackground="@drawable/nav_view_item_background"

then the selected item will be highlighted.

if you want to change the text color then set

app:itemTextColor="@drawable/nav_view_item_textcolor"

and create a selector for it like

<selector xmlns:android="http://schemas.android.com/apk/res/android">
      <item android:color="@android:color/white" android:state_checked="true" />
     <item android:color="@color/primary" />
</selector>
