BottomSheet Spinner

Spinner with bottom sheet dialog for Android

What is this?

This is a small library for spinner view with displaying options in bottom sheet dialog. This view doesn't improve or extend the default android Spinner. The library doesn't support any other types of showing menu, only bottom sheet dialog.

Library based on BottomSheetDialogFragment and RecyclerView

Requirements

• Material Components
• AndroidX
• Min SDK 21+

Install

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

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

Add this line to your app's dependencies:

implementation 'com.github.nestoleh:bottomsheet-spinner:version'

Using

1. Add view to your layout file

2. Create an adapter and view holder for spinner items. You can use common BottomSheetSpinnerAdapter as base class or list-based version SimpleBottomSheetSpinnerAdapter. View holder class has to extend BottomSheetSpinnerItemViewHolder. You can use different view layouts and view holders for selected view and dropdown view.

3. Add your adapter to BottomSheetSpinner

val spinnerAdapter = MySpinnerAdapter(listOf("One", "Two", "Three"))
spinnerView.setAdapter(spinnerAdapter)

4. Enjoy! 🎉

P.S. Also you can see sample of using in sample-application

Styling

View styling

BottomSheetView extends FrameLayout, so you can use all styling options supported by FrameLayout. The selected view will be placed inside BottomSheetView as a child view, so don't use theme options that can change child view displaying if you don't want it.

Bottom sheet dialog styling

BottomSheetView supports the next custom parameters for dialog style^

• bss_dialogTitle - used to set dialog title, title doesn't show if it empty or null.
• bss_dialogTheme - used to set the theme of bottom sheet dialog and to set styles for dialog inner elements. You can set bss_dialogRecyclerViewStyle and bss_dialogTitleStyle as parameters of this theme.

Sample:

layout.xml

styles.xml
