         <com.ss.bottomnavigation.BottomNavigation
            android:id="@+id/bottom_navigation"
            android:layout_width="match_parent"
            android:layout_height="56dp"
            android:layout_alignParentBottom="true"
            android:background="@color/colorPrimary">
            <com.ss.bottomnavigation.TabItem
                android:id="@+id/tab_home"
                android:layout_width="0dp"
                android:layout_height="match_parent"
                android:layout_weight="1"
                app:tab_text="Home"
                app:tab_icon="@drawable/ic_home_white_24dp"
                />
            <com.ss.bottomnavigation.TabItem
                android:id="@+id/tab_images"
                android:layout_width="0dp"
                android:layout_height="match_parent"
                android:layout_weight="1"
                app:tab_text="Images"
                app:tab_icon="@drawable/ic_image_black_24dp"
                />
            <com.ss.bottomnavigation.TabItem
                android:id="@+id/tab_camera"
                android:layout_width="0dp"
                android:layout_height="match_parent"
                android:layout_weight="1"
                app:tab_text="Camera"
                app:tab_icon="@drawable/ic_camera_white_24dp"
                />
            <com.ss.bottomnavigation.TabItem
                android:id="@+id/tab_products"
                android:layout_width="0dp"
                android:layout_height="match_parent"
                android:layout_weight="1"
                app:tab_text="Products"
                app:tab_icon="@drawable/ic_products_white_24dp"
                />
            <com.ss.bottomnavigation.TabItem
                android:id="@+id/tab_more"
                android:layout_width="0dp"
                android:layout_height="match_parent"
                android:layout_weight="1"
                app:tab_text="More"
                app:tab_icon="@drawable/ic_more_white_24dp"
                />
         </com.ss.bottomnavigation.BottomNavigation>

       android:layout_width="match_parent"
       android:layout_height="56dp"

Java

You can set onSelectedItemChangeListener in java like this:

notice: all tab items in xml must have id to determinate which item is selected.

BottomNavigation bottomNavigation=(BottomNavigation)findViewById(R.id.bottom_navigation);
        bottomNavigation.setOnSelectedItemChangeListener(new OnSelectedItemChangeListener() {
            @Override
            public void onSelectedItemChanged(int itemId) {
                switch (itemId){
                    case R.id.tab_home:
                        transaction=getSupportFragmentManager().beginTransaction();
                        transaction.replace(R.id.frame_fragment_containers,new FragmentA());
                        break;
                    case R.id.tab_images:
                        transaction=getSupportFragmentManager().beginTransaction();
                        transaction.replace(R.id.frame_fragment_containers,new FragmentB());
                        break;
                    case R.id.tab_camera:
                        transaction=getSupportFragmentManager().beginTransaction();
                        transaction.replace(R.id.frame_fragment_containers,new FragmentF());
                        break;
                    case R.id.tab_products:
                        transaction=getSupportFragmentManager().beginTransaction();
                        transaction.replace(R.id.frame_fragment_containers,new FragmentC());
                        break;
                    case R.id.tab_more:
                        transaction=getSupportFragmentManager().beginTransaction();
                        transaction.replace(R.id.frame_fragment_containers,new FragmentD());
                        break;
                }
                transaction.commit();
            }
        });

Change default item

you can change default selected tab item by add this line to your code (before setOnSelectedItemChangeListener):

    bottomNavigation.setDefaultItem(1); // change default selected tab item by position

Set custom font

for set custom font on bottom navigation, you simply need add this line to your code:

    bottomNavigation.setTypeface(myTypeface);
