Bottom navigation menu items showing filled color. I want to display the exact icons that I added in the drawable folder

Question

The way that I have done in the code section. dynamically generted menu code.

 for(int i = 0;i<menuDetails.size();i++){
        int res_id = this.getResources().getIdentifier("@drawable/"+menuDetails.get(i).getMenu_icon(), null, this.getPackageName());
        navigation.getMenu()
                .add(Menu.NONE, i, Menu.NONE, menuDetails.get(i).getTitle())
                .setIcon(res_id).setChecked(false)
                .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
    }

XML file:

  <FrameLayout
        android:id="@+id/home_footer"
        android:layout_width="match_parent"
        android:layout_height="@dimen/bottom_nav_height"
        android:layout_alignParentBottom="true">
        <android.support.design.widget.BottomNavigationView
            android:id="@+id/navigation"
            android:layout_width="match_parent"
            android:layout_height="@dimen/bottom_nav_height"
            android:theme="@style/Widget.BottomNavigationView"
            app:elevation="5dp"
            app:itemIconTint="@drawable/nav_selection"
            app:itemTextColor="@color/welcome_text_color"
            app:labelVisibilityMode="labeled"
            app:layout_constraintBottom_toBottomOf="parent" />
        <!--   app:itemIconTint="@drawable/nav_selection" -->
    </FrameLayout>

nav_selection drawable file:

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

output(actually the home button is another layout to fit into the centre, I need the icon like home button in the navigation View).

Answer 1

In the BottomNavigationView the app:itemIconTint takes a ColorStateList.

Each item must define an android:color attribute, which may be an HTML-style hex color, a reference to a color resource, or -- in API 23 and above -- a theme attribute that resolves to a color.

Instead you are trying to use a StateListDrawable and it doesn't work.

The only workaround to avoid tinting and use original icons is to use (app:itemIconTint="@null" in the XML doesn't work)

bottomNavigationView.setItemIconTintList(null);

In any case I suggest not using it.
