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 = FindViewById<BottomNavigationViewEx>(Resource.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);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 try in demo. For example, I can't change the current checked item by code. So I write a class extends it to provide some useful method.
You no need to worry about stability. Because I minimise modifying by reflecting.
Thanks
