using different Background Color of Bottom NavigationBar Tab


I'm adding a BottomNavigationView to a project, and I would like to have a different background color for each bottom tab.Using a different color with android:state_selected="true" in a color selector resource file doesn't seem to work.I also tried to entered more things like android:state_focused="true" or android:state_enabled="true", no effect unfortunately.

(BottomnavigationView)

 <android.support.design.widget.BottomNavigationView
        android:id="@+id/bottomNavigationView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:itemIconTint="@color/menu_txt_color"
        app:itemTextColor="@color/menu_txt_color"
        android:background="@drawable/bnv_tab_item_foreground"
        app:layout_constraintBottom_toTopOf="@+id/guideline14"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintHorizontal_bias="1.0"
        app:layout_constraintStart_toStartOf="parent"
        app:menu="@menu/navigation" />

(Color Selector)

<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/add_child" android:state_checked="true" android:state_pressed="true"/>
    <item android:drawable="@color/light_blue" android:state_checked="false"/>

</selector>

(My Menu Resource)

<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">


    <item
        android:id="@+id/tab1"
        android:layout_height="wrap_content"
        android:icon="@drawable/baby3"
        android:checked="true"
        android:title="hello"
        app:showAsAction="always|withText" />

    <item
        android:id="@+id/tab2"
        android:icon="@drawable/baby2"
        android:title="heelo2"
        app:showAsAction="always|withText|collapseActionView" />


    <item
        android:id="@+id/tab3"
        android:checkable="false"
        android:icon="@drawable/baby2"
        android:title="hello 3"
        app:showAsAction="always|withText" />

    <item
        android:id="@+id/tab4"
        android:checkable="false"
        android:icon="@drawable/baby3"
        android:title="heelo 4"
        app:showAsAction="always|withText" />

</menu>

Tabs are highlighted when i selected ,I want BottomNavigationBar tabs like Instagram, i also tried (How to create bottom navigation bar similar to instagram) but it no help..

Solution

  • try this way

    use Custom Action layout as menu

    <item
        android:id="@+id/nav_1"
        android:title=""
        app:actionLayout="@layout/custom_layout"/>
    
    <item
        android:id="@+id/nav_2"
        android:title=""
        app:actionLayout="@layout/custom_layout"/>
    
    <item
        android:id="@+id/nav_3"
        android:title=""
        app:actionLayout="@layout/custom_layout"/>
    
    <item
        android:id="@+id/nav_4"
        android:title=""
        app:actionLayout="@layout/custom_layout"/>
    
    <item
        android:id="@+id/nav_5"
        android:title=""
        app:actionLayout="@layout/custom_layout"/>
    

    custom_layout will be like this in layout folder

    <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical">
    
        <Button
            android:id="@+id/button"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:layout_gravity="center_vertical"
            android:background="@drawable/selector"
            android:layout_weight="1"
            android:gravity="center_vertical"/>
    
    </LinearLayout>
    

    at Activity where you using BottomNavigationView you can do like this

    try{
        View view = navigationView.getMenu().findItem(R.id.nav_1).getActionView();
                Button button = (Button) view.findViewById(R.id.button);
                 //button.setOnClickListener(this);
                 // similarly for others menu in BottomNavigationView
            } catch (Exception e) {
                AppLogger.getInstance().writeException(e);
            }
    

    Update

    selector.xml

    <?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:state_selected="true" android:color="@color/Primary" />
        <item android:state_focused="false" android:color="@color/IconsColor" />
        <item android:state_selected="false" android:color="@color/IconsColor" />
        <item android:state_focused="true" android:color="@color/Primary" />
        <item android:state_pressed="true" android:color="@color/white" />
        <item android:color="@color/tabsScrollColor" />
    </selector>
