Inherited functions

From class Picker

`Unit`	`addOnValueChangedListener(listener: Picker.PickerValueListener!)` Register a callback to be invoked when the picker's value has changed.
`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.
`Unit`	`onColumnValueChanged(columnIndex: Int, newValue: Int)` Classes extending `Picker` can override this function to supply the behavior when a list has been scrolled. Subclass may call `setColumnValue(int, int, * boolean)` and or `setColumnAt(int, PickerColumn)`. Subclass should not directly call `PickerColumn#setCurrentValue(int)` which does not update internal state or notify listeners.
`Boolean`	`onRequestFocusInDescendants(direction`
