At Cleveroad we’ve recently come to realize that navigation through categories in an app using nothing but a navigation panel is pretty boring and trivial. That’s why, armed with our designer’s creativity, we introduce you our new component for Android-based applications -- LoopBar. The idea was to make the navigation menu right at fingerprints, in a tab bar. What's more the view has a few specific features that make it stand out from the crowd of similar ones. So, try out the LoopBar library in your app and you’ll see the difference.

If you strive to create an application with unusual looks and navigation, you are welcome to use the LoopBar library. It’s really easy to integrate and can add spice to any app!

If you need more details on how you can use the component and what benefits it provides, read our blog post: Case Study: Loop Bar for Android

by gradle :

dependencies {
    compile "com.cleveroad:loopbar:1.0.0"
}

or just download zip and import module "LoopBar-widget" to be able to modify the sources

View consist from two parts:

• An infinite list of your selectable groups
• Selected view

A list of groups will be infinite if all adapter items didn't fit on screen in other case it will be a static list. Selected view by request could overlay layout on screen on which it placed. Widget has horizontal and vertical layouts and also start or end gravity of selected view.

You are allowed to use any RecyclerView adapter, which you want. Concrete infinite scroll logic is fully incapsulated

Android Studio layouts preview is supported.

    <com.cleveroad.loopbar.widget.LoopBarView
        android:id="@+id/endlessView"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:enls_placeholderId="@id/placeHolder"
        app:enls_orientation="horizontal"
        app:enls_selectionGravity="start"
        app:enls_selectionMargin="10dp"
        app:enls_overlaySize="5dp"
        app:enls_selectionInAnimation="@animator/enls_scale_restore"
        app:enls_selectionOutAnimation="@animator/enls_scale_small"
        app:enls_selectionBackground="@android:color/holo_blue_dark"
        />

enls_overlaySize & enls_placeholderId are used for overlay feature.

To initialize items in widget and work with it you should setup adapter to it and add item click listener:

LoopBarView loopBarView = findViewById(..);
categoriesAdapter = new SimpleCategoriesAdapter(MockedItemsFactory.getCategoryItemsUniq());
loopBarView.setCategoriesAdapter(categoriesAdapter);
loopBarView.addOnItemClickListener(this);

Here SimpleCategoriesAdapter is used which required collection of ICategoryItem objects (to draw default view with icon and text). And also you are free to use your own adapter with custom items.

To control wrapped RecyclerView animations you are able to use getWrappedRecyclerView().
