 repositories {
  ...
  maven { url "https://jitpack.io" }
  maven { url "https://maven.google.com" }
 }
}

Step 2. Add the dependency

  1. old version support lib is 25 or 26

compile "com.android.support:design:26.+"
  1. new version support lib = 28
implementation 'com.github.ittianyu:BottomNavigationViewEx:2.0.2'

Manual:

Downloading BottomNavigationViewEx.java and copying it to you project.

Getting started

Adding a custom widget in xml :

<com.ittianyu.bottomnavigationviewex.BottomNavigationViewEx
    android:id="@+id/bnve"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:layout_alignParentBottom="true"
    android:background="@color/colorPrimary"
    app:itemIconTint="@color/selector_item_color"
    app:itemTextColor="@color/selector_item_color"
    app:menu="@menu/menu_navigation_with_view_pager" />

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();
                    }
                });
    }
    

Other usage in BottomNavigationViewEx

You can see the demo.

Usage in BottomNavigationView

Other usage is the same as official BottomNavigationView. You can click here for detail.

ProGuard

If you are using ProGuard you might need to add the following option:

-keep public class android.support.design.widget.BottomNavigationView { *; }
-keep public class android.support.design.internal.BottomNavigationMenuView { *; }
-keep public class android.support.design.internal.BottomNavigationPresenter { *; }
-keep public class android.support.design.internal.BottomNavigationItemView { *; }

References

The lib is based on BottomNavigationView in Support Library 25 design.

I found it was inflexible when I tried the demo. For example, I couldn't change the currently checked item through code. So I wrote a class to extend it to provide some useful methods.

You have no need to worry about stability, because I minimised the modifications through reflection.
