Standalone autocomplete component

Overview
Setup

Overview

The SDK provides a standalone AI autocomplete component, called BotAutocompleteFragment.
This UI component can be located in your fragment, activity, etc, and will automatically connect to a bot AI source, for autocomplete suggestions fetching.

The standalone component support self state restoring on device rotation mode changes.
Suggestions will not be displayed while the device is on Landscape mode. Text changes will be registaered and the relevant suggestions will be displayed once the device is back on Portrait mode.

Setup

Create autocomplete parameters

BotAutocompleteFragment uses BotCompletionViewModel as its parameters source. BotCompletionViewModel should be obtained from ViewModelProvider, and configured with the autocomplete parameters as needed.

Obtain BotCompletionViewModel {: .strong-sub-title}
When obtaining the BotCompletionViewModel, use the containing activity as the source for the ViewModelProvider.

val botViewModel = ViewModelProviders.of(activity).
                                get(BotCompletionViewModel::class.java)

Apply autocomplete parameters values {: .strong-sub-title}
Once you have the BotCompletionViewModel instance, set its properties as needed, for the autocomplete functionality and display.
- botChat_Mandatory - In case the app already use an active bot chat, set this parameter to point to your reference. If not, set the provided instance with a BotAccount.
```
val botViewModel = ... // Obtain...
botViewModel.botChat.account = BotAccount(...) 
// or set the botViewModel.botChat, if there's already an active instance 
// botViewModel.botChat = myBotChatInstance
```
- uiConfig_Optional - Set UI properties to customize the view look as needed.
- openingQuery_Optional - If configured, will automatically be inserted to the input field.
- onError, onSelection and onConversationIdUpdate_Optional - Can be observed in order to be updated with the component events.

Component display

The BotAutocompleteFragment can be added to an activity or to another fragment.

fragmentManager.beginTransaction()
            .add(R.id.root_layout, BotAutocompleteFragment()).commit()

Listening to events

Optional, set observers to the events you would like to be notified of.

val botViewModel =  ... // obtain 
// observe errors:
botViewModel.onError.observe(this, Observer{ error ->
        error?.run { 
            //do something
        }
    })
// observe suggestions selection:
botViewModel.onSelection.observe(this, Observer { selection ->
        // a utility method "getArticle" is passed over Selection object
        // BotAutocompleteFragment provides a "getArticle" method as well that can be used.
        selection?.getArticle?.invoke(selection.articleId) { result ->
            result.error?.run { 
                // handle error 
            } ?: result.data?.run { 
                // handle response data of type `Article`
            }
        }
    })
// observe conversationId changes:
botViewModel.onConversationIdUpdate.observe(this, Observer { id ->
        // do something
    })

UI configurations

The component UI configurations are defined by AutocompleteViewUIConfig. In order to change the default UI look, create instance of AutocompleteViewUIConfig, configure its properties as needed and set it to BotCompletionViewModel.uiConfig propety.

val botViewModel = ViewModelProviders.of(activity)...
val customedUIConfig = ChatAutocompleteUIConfig(context).apply { 
    // change properties values
}
botViewModel.uiConfig = customedUIConfig

Tip: In order to preseve the chat, on state restoring, of the containing activity/fragment, do not override the BotAccount on the BotCompletionViewModel object if already exists.
val botViewModel = ViewModelProviders.of(activity!!).get(BotCompletionViewModel::class.java);       
if (!botViewModel.botChat.hasSession) {
    botViewModel.botChat.account = BotAccount(...)
}
