SeslAppPickerView

abstract class SeslAppPickerView @JvmOverloads constructor(context: Context, attrs: AttributeSet? = null, defStyleAttr: Int = 0) : RecyclerView, RecyclerView.RecyclerListener, AppPickerAdapter.OnBindListener, AppPickerEvent, AppPickerState, LogTag(source)

An abstract base class for views that display a list or grid of applications, allowing users to pick one or more.

This class extends RecyclerView and implements several interfaces to manage application data, selection state, and user interactions.

Key features:

Supports both list and grid layouts.
Handles different ordering options for the application list.
Allows customization of subheader appearance (solid or transparent).
Provides methods for adding, removing, and updating application items.
Manages item selection state.
Integrates with AppDataRepository for data fetching and SelectStateLoader for managing selection.
Uses strategy pattern for customizing data handling and presentation logic.

Subclasses must implement getAppPickerAdapter and getLayoutManager to provide the specific adapter and layout manager for the chosen view type (list or grid).

XML attributes:

strategy: (Optional) The fully qualified class name of the Strategy implementation to use. Defaults to androidx.picker.controller.strategy.AppItemStrategy.
appPickerContextClass: (Optional) The fully qualified class name of the androidx.picker.di.AppPickerContext implementation to use. Defaults to androidx.picker.di.AppPickerContext.
seslRoundedCorner: (Optional) Integer value to set the rounded corner radius for items. Defaults to 15.
pickerApp_subHeaderType: (Optional) Defines the subheader style. Can be SUBHEADER_TYPE_SOLID (0) or SUBHEADER_TYPE_TRANSPARENT (1). Defaults to SUBHEADER_TYPE_SOLID.
