Adding a custom widget in xml :

<com.ittianyu.bottomnavigationviewex.BottomNavigationViewEx
    android:id="@+id/bnve"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"

Binding view in Activity:

BottomNavigationViewEx bnve = (BottomNavigationViewEx) findViewById(R.id.bnve);

Disable all animations

bnve.enableAnimation(false);
bnve.enableShiftingMode(false);
bnve.enableItemShiftingMode(false);

Custom text and icon size

bnve.setIconSize(widthDp, heightDp);
bnve.setTextSize(sp);

Binding with ViewPager

// set adapter
adapter = new VpAdapter(getSupportFragmentManager(), fragments);
bind.vp.setAdapter(adapter);

// binding with ViewPager
bind.bnve.setupWithViewPager(bind.vp);

Add badge view

  1. Add badge lib
    compile 'q.rorbin:badgeview:1.1.0'
  2. Bind bottom view
    // add badge
addBadgeAt(2, 1);

private Badge addBadgeAt(int position, int number) {
    // add badge
    return new QBadgeView(this)
            .setBadgeNumber(number)
            .setGravityOffset(12, 2, true)
            .bindTarget(bind.bnve.getBottomNavigationItemView(position))
            .setOnDragStateChangedListener(new Badge.OnDragStateChangedListener() {
                @Override
                public void onDragStateChanged(int dragState, Badge badge, View targetView) {
                    if (Badge.OnDragStateChangedListener.STATE_SUCCEED == dragState)
                        Toast.makeText(BadgeViewActivity.this, R.string.tips_badge_removed, Toast.LENGTH_SHORT).show();
                }
