Inherited functions

From class Picker

`Unit`	`addOnValueChangedListener(listener: Picker.PickerValueListener!)` Register a callback to be invoked when the picker's value has changed.
`Boolean`	`dispatchKeyEvent(event: KeyEvent!)`
`Float`	`getActivatedVisibleItemCount()` Returns number of visible items showing in a column when it's activated. The default value is 3.
`PickerColumn!`	`getColumnAt(colIndex: Int)` Get nth PickerColumn.
`Int`	`getColumnsCount()` Get number of PickerColumns.
`Int`	`getPickerItemHeightPixels()` Classes extending `Picker` can choose to override this method to supply the `Picker`'s column's single item height in pixels.
`Int`	`getPickerItemLayoutId()` Classes extending `Picker` can call `setPickerItemLayoutId(int)` to supply the `Picker`'s item's layout id
`Int`	`getPickerItemTextViewId()` Returns the `Picker`'s item's `TextView`'s id from within the layout provided by `Picker#getPickerItemLayoutId()` or 0 if the layout provided by `Picker#getPickerItemLayoutId()` is a {link TextView}.
`Int`	`getSelectedColumn()` Get current activated column index.
`CharSequence!`	`getSeparator()` Gets separator string between columns.
`MutableList<CharSequence!>!`	`getSeparators()` Returns the list of separators that will be populated between the picker column fields.
`Float`	`getVisibleItemCount()` Returns number of visible items showing in a column when it's not activated. The default value is 1.
`Boolean`	`onRequestFocusInDescendants(direction: Int, previouslyFocusedRect: Rect!)`
`Unit`	`removeOnValueChangedListener(listener: Picker.PickerValueListener!)` Remove a previously installed value changed callback
`Unit`	`requestChildFocus(child: View!, focused: View!)`
`Unit`	`setActivated(activated: Boolean)`
`Unit`	`setActivatedVisibleItemCount(visiblePickerItems: Float)` Changes number of visible items showing in a column when it's activated. The default value is 3.
`Unit`	`setColumnAt(columnIndex: Int, column: PickerColumn!)` When column labels change or column range changes, call this function to re-populate the selection list. Note this function cannot be called from RecyclerView layout/scroll pass.
`Unit`	`setColumnValue(columnIndex: Int, value: Int, runAnimation: Boolean)` Manually set current value of a column. The function will update UI and notify listeners.
`Unit`	`setColumns(columns: MutableList<PickerColumn!>!)` Set columns and create Views.
`Unit`	`setPickerItemLayoutId(@LayoutRes pickerItemLayoutId: Int)` Sets the layout to use for picker items.
`Unit`	`setPickerItemTextViewId(@IdRes textViewId: Int)` Sets the `Picker`'s item's `TextView`'s id from within the layout provided by `Picker#getPickerItemLayoutId()` or 0 if the layout provided by `Picker#getPickerItemLayoutId()` is a {link TextView}.
`Unit`	`setSelectedColumn(columnIndex: Int)` Change current selected column. Picker shows multiple items on selected column if Picker has focus. Picker shows multiple items on all column if Picker has no focus (e.g. a Touchscreen screen).
`Unit`	`setSeparator(separator: CharSequence!)`
