Change the color of a checked menu item in a navigation drawer
I am using the new Android Design Support library to implement a navigation drawer in my application.
I can't figure out how to change the color of a selected item!
Here is the xml of the menu :
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<group android:checkableBehavior="single">
<item
android:id="@+id/navigation_item_1"
android:icon="@drawable/ic_1"
android:title="@string/navigation_item_1"/>
<item
android:id="@+id/navigation_item_2"
android:icon="@drawable/ic_2"
android:title="@string/navigation_item_2"/>
</group>
And here is the navigationview xml which is placed inside a android.support.v4.widget.DrawerLayout
:
<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/black"
app:itemTextColor="@color/primary_text"
app:menu="@menu/menu_drawer">
<TextView
android:id="@+id/main_activity_version"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:layout_marginBottom="@dimen/activity_vertical_margin"
android:layout_marginLeft="@dimen/activity_horizontal_margin"
android:textColor="@color/primary_text" />
</android.support.design.widget.NavigationView>
Thank you for your help !
[EDIT] I have already looked at solutions such as this one : Change background color of android menu.
It seems to be quite a hack and I thought that with the new Design Support Library, something cleaner would have been introduced?
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.
I believe app:itemBackground
expects a drawable. So follow the steps below :
Make a drawable file highlight_color.xml
with following contents :
<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="rectangle">
<solid android:color="YOUR HIGHLIGHT COLOR"/>
</shape>
Make another drawable file nav_item_drawable.xml
with following contents:
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:drawable="@drawable/highlight_color" android:state_checked="true"/>
</selector>
Finally add app:itemBackground
tag in the NavView :
<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/black"
app:itemTextColor="@color/primary_text"
app:itemBackground="@drawable/nav_item_drawable"
app:menu="@menu/menu_drawer">
here the highlight_color.xml file defines a solid color drawable for the background. Later this color drawable is assigned to nav_item_drawable.xml selector.
This worked for me. Hopefully this will help.

Though the above mentioned answer gives you fine control over some properties, but the way I am about to describe feels more SOLID and is a bit COOLER.
So what you can do is, you can define a ThemeOverlay in the styles.xml
for the NavigationView like this :
<style name="ThemeOverlay.AppCompat.navTheme">
<!-- Color of text and icon when SELECTED -->
<item name="colorPrimary">@color/color_of_your_choice</item>
<!-- Background color when SELECTED -->
<item name="colorControlHighlight">@color/color_of_your_choice</item>
</style>
now apply this ThemeOverlay to app:theme
attribute of NavigationView, like this:
<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:theme="@style/ThemeOverlay.AppCompat.navTheme"
app:headerLayout="@layout/drawer_header"
app:menu="@menu/menu_drawer">
I hope this will help.
One need to set NavigateItem
checked true whenever item in NavigateView
is clicked
//listen for navigation events
NavigationView navigationView = (NavigationView)findViewById(R.id.navigation);
navigationView.setNavigationItemSelectedListener(this);
// select the correct nav menu item
navigationView.getMenu().findItem(mNavItemId).setChecked(true);
Add NavigationItemSelectedListener
on NavigationView
@Override
public boolean onNavigationItemSelected(final MenuItem menuItem) {
// update highlighted item in the navigation menu
menuItem.setChecked(true);
mNavItemId = menuItem.getItemId();
// allow some time after closing the drawer before performing real navigation
// so the user can see what is happening
mDrawerLayout.closeDrawer(GravityCompat.START);
mDrawerActionHandler.postDelayed(new Runnable() {
@Override
public void run() {
navigate(menuItem.getItemId());
}
}, DRAWER_CLOSE_DELAY_MS);
return true;
}
Here is the another way to achive this:
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
item.setOnMenuItemClickListener(new MenuItem.OnMenuItemClickListener() {
@Override
public boolean onMenuItemClick(MenuItem item) {
item.setEnabled(true);
item.setTitle(Html.fromHtml("<font color='#ff3824'>Settings</font>"));
return false;
}
});
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
