An android lib for enhancing BottomNavigationView.

Style

Attention: Something wrong on Android 4.x

With ViewPager

Add ViewBadger

Center Floating Action Button

compileSdkVersion >= 25

Step 1. Add it in your root build.gradle at the end of repositories:

allprojects {
	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.github.ittianyu:BottomNavigationViewEx:1.2.4'
compile "com.android.support:design:26.+"

2. new version support lib = 28

implementation 'com.github.ittianyu:BottomNavigationViewEx:2.0.4'
implementation "com.android.support:design:28.0.0"

3. AndroidX use new version，and add config into gradle.properties

android.useAndroidX=true
android.enableJetifier=true

Downloading BottomNavigationViewEx.java and copying it to you project.

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);

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

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

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

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

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();
                   }
               });
   }
   

You can see the demo.

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

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 { *; }

-keep public class com.google.android.material.bottomnavigation.BottomNavigationView { *; }
-keep public class com.google.android.material.bottomnavigation.BottomNavigationMenuView { *; }
-keep public class com.google.android.material.bottomnavigation.BottomNavigationPresenter { *; }
-keep public class com.google.android.material.bottomnavigation.BottomNavigationItemView { *; }

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.
