Answer 1

You can use this for showing both text and icons on BottomNevigationView for 3 to 5 items and stop shifting.

 app:labelVisibilityMode="labeled"

But you will will face a problem of long text cutting on BottmNevigationView for 5 items. for that ,I found a good solutions for stop shifting of text as well as icons of BottomNevigationView. You can also stop shifting of text as well as Icons on BottomNevigationView also. Snipshots of code is given here.

1. Add this some line of code in BottomNevigationView as shown

<android.support.design.widget.BottomNavigationView
    android:id="@+id/bottom_navigation"
    android:layout_width="match_parent"
    android:layout_height="@dimen/seventy_dp"
    android:layout_semitransparent="true"
    android:background="@color/colorBottomNev"
    android:showAsAction="always|withText"
    app:itemIconTint="@drawable/bottom_navigation_colors"
    app:itemTextColor="@drawable/bottom_navigation_colors"
    app:itemTextAppearanceActive="@style/BottomNavigationViewTextStyle"
    app:itemTextAppearanceInactive="@style/BottomNavigationViewTextStyle"
    app:menu="@menu/bottom_navigation_menu"
    app:labelVisibilityMode="labeled"/>

2. Add Menu Items like as follows:-

 <?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto">

    <item
        android:id="@+id/action_catalogue"
        android:icon="@drawable/catalogue"
        android:title="@string/catalogue"
        android:enabled="true"
        app:showAsAction="ifRoom" />

    <item
        android:id="@+id/action_contracts"
        android:icon="@drawable/contract"
        android:title="@string/contracts"
        android:enabled="true"
        app:showAsAction="ifRoom" />

    <item
        android:id="@+id/action_prospects"
        android:icon="@drawable/prospect"
        android:title="@string/prospects"
        android:enabled="true"
        app:showAsAction="ifRoom" />

    <item
        android:id="@+id/action_performance"
        android:icon="@drawable/performance"
        android:title="@string/performance"
        android:enabled="true"
        app:showAsAction="ifRoom" />

    <item
        android:id="@+id/action_advance"
        android:icon="@drawable/advance"
        android:title="@string/advance"
        android:enabled="true"
        app:showAsAction="ifRoom" />

</menu>

3.Add this style in style.xml file:

 <style name="BottomNavigationViewTextStyle">
            <item name="android:fontFamily">@font/montmedium</item>
            <item name="android:textSize">10sp</item>
            <item name="android:duplicateParentState">true</item>
            <item name="android:ellipsize">end</item>
            <item name="android:maxLines">1</item>
        </style>

4)Add these in Dimen folder

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:tools="http://schemas.android.com/tools">
    <dimen name="design_bottom_navigation_text_size" tools:override="true">10sp</dimen>
    <dimen name="design_bottom_navigation_active_text_size" tools:override="true">10sp</dimen>
</resources>

Since support library 28.0.0-alpha1:

<android.support.design.widget.BottomNavigationView
    app:labelVisibilityMode="labeled" />

Answer 3

If you are using support:design:28.0.0 add this line app:labelVisibilityMode="unlabeled" to your BottomNavigationView

Answer 4

just want to add that above this method disableShiftMode add below code too. @SuppressLint("RestrictedApi")

Answer 6

To completely remove animations:

If you also want to get rid of that annoying little top margin animation, you need more reflection code. Here's the complete solution that removes any animation:

@SuppressLint("RestrictedApi")
private static void disableShiftMode(BottomNavigationView view) {
    BottomNavigationMenuView menuView = (BottomNavigationMenuView) view.getChildAt(0);
    try {
        Field shiftingMode = menuView.getClass().getDeclaredField("mShiftingMode");
        shiftingMode.setAccessible(true);
        shiftingMode.setBoolean(menuView, false);
        shiftingMode.setAccessible(false);
        for (int i = 0; i < menuView.getChildCount(); i++) {
            BottomNavigationItemView item = (BottomNavigationItemView) menuView.getChildAt(i);
            item.setShiftingMode(false);

            Field shiftAmount = item.getClass().getDeclaredField("mShiftAmount");
            shiftAmount.setAccessible(true);
            shiftAmount.setInt(item, 0);
            shiftAmount.setAccessible(false);

            item.setChecked(item.getItemData().isChecked());
        }
    } catch (NoSuchFieldException e) {
        Timber.e(e, "Unable to get fields");
    } catch (IllegalAccessException e) {
        Timber.e(e, "Unable to change values");
    }
}

And make sure to add that to your proguard configuration file:

-keepclassmembers class android.support.design.internal.BottomNavigationMenuView { 
    boolean mShiftingMode; 
}
-keepclassmembers class android.support.design.internal.BottomNavigationItemView { 
    int mShiftAmount;
}
