Known direct subclasses

DatePicker, PinPicker, TimePicker

`DatePicker`	`DatePicker` is a directly subclass of `Picker`.
`PinPicker`	`Picker` subclass for allowing the user to enter a numerical PIN.
`TimePicker`	`TimePicker` is a direct subclass of `Picker`.

Picker is a widget showing multiple customized PickerColumns. The PickerColumns are initialized in setColumns. Call setColumnAt if the column value range or labels change. Call setColumnValue to update the current value of PickerColumn.

Picker has two states and will change height:

isActivated is true: Picker shows typically three items vertically (see getActivatedVisibleItemCount}. Columns other than getSelectedColumn still shows one item if the Picker is focused. On a touch screen device, the Picker will not get focus so it always show three items on all columns. On a non-touch device (a TV), the Picker will show three items only on currently activated column. If the Picker has focus, it will intercept DPAD directions and select activated column.
isActivated is false: Picker shows one item vertically (see getVisibleItemCount) on all columns. The size of Picker shrinks.

Summary

Nested types
`public interface Picker.PickerValueListener` Listener for `Picker` value changes.

Public constructors
`Picker(@NonNull Context context, @Nullable AttributeSet attributeSet)` Creates a Picker widget.
`Picker( @NonNull Context context, @Nullable AttributeSet attrs, int defStyleAttr )` Creates a Picker widget.

Public methods
`void`	`addOnValueChangedListener(@NonNull Picker.PickerValueListener listener)` Register a callback to be invoked when the picker's value has changed.
`boolean`	`dispatchKeyEvent(KeyEvent event)`
`float`	`getActivatedVisibleItemCount()` Returns number of visible items showing in a column when it's activated.
`@Nullable PickerColumn`	`getColumnAt(int colIndex)` Get nth PickerColumn.
`int`	`getColumnsCount()` Get number of PickerColumns.
`final @LayoutRes int`	`getPickerItemLayoutId()` Classes extending `Picker` can call `setPickerItemLayoutId` to supply the `Picker`'s item's layout id
`final @IdRes int`	`getPickerItemTextViewId()` Returns the `Picker`'s item's `TextView`'s id from within the layout provided by `getPickerItemLayoutId` or 0 if the layout provided by `getPickerItemLayoutId` is a {link TextView}.
`int`	`getSelectedColumn()` Get current activated column index.
`final CharSequence`	`getSeparator()` This method is deprecated. Use `getSeparators`
`final @NonNull List<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.
`void`	`onColumnValueChanged(int columnIndex, int newValue)` Classes extending `Picker` can override this function to supply the behavior when a list has been scrolled.
`void`	`removeOnValueChangedListener( @NonNull Picker.PickerValueListener listener )` Remove a previously installed value changed callback
`void`	`requestChildFocus(View child, View focused)`
`void`	`setActivated(boolean activated)`
`void`	`setActivatedVisibleItemCount(float visiblePickerItems)` Changes number of visible items showing in a column when it's activated.
`void`	`setColumnAt(int columnIndex, @NonNull PickerColumn column)` When column labels change or column range changes, call this function to re-populate the selection list.
`void`	`setColumnValue(int columnIndex, int value, boolean runAnimation)` Manually set current value of a column.
`void`	`setColumns(@NonNull List<PickerColumn> columns)` Set columns and create Views.
`final void`	`setPickerItemLayoutId(@LayoutRes int pickerItemLayoutId)` Sets the layout to use for picker items.
`final void`	`setPickerItemTextViewId(@IdRes int textViewId)` Sets the `Picker`'s item's `TextView`'s id from within the layout provided by `getPickerItemLayoutId` or 0 if the layout provided by `getPickerItemLayoutId` is a {link TextView}.
`void`	`setSelectedColumn(int columnIndex)` Change current selected column.
`final void`	`setSeparator(@NonNull CharSequence separator)` Sets separator String between Picker columns.
`final void`	`setSeparators(@NonNull List<CharSequence> separators)` Sets the list of separators that will be populated between the Picker columns.
`void`	`setVisibleItemCount(float pickerItems)` Changes number of visible items showing in a column when it's not activated.

Protected methods
`int`	`getPickerItemHeightPixels()` Classes extending `Picker` can choose to override this method to supply the `Picker`'s column's single item height in pixels.
`boolean`	`onRequestFocusInDescendants(int direction, Rect previouslyFocusedRect)`

onColumnValueChanged

Added in 1.1.0

public void onColumnValueChanged(int columnIndex, int newValue)

Classes extending Picker can override this function to supply the behavior when a list has been scrolled. Subclass may call setColumnValue and or setColumnAt. Subclass should not directly call setCurrentValue which does not update internal state or notify listeners.

Parameters
`int columnIndex`	index of which column was changed.
`int newValue`	A new value desired to be set on the column.

Added in 1.1.0

public void removeOnValueChangedListener(

setPickerItemLayoutId

Added in 1.1.0

public final void setPickerItemLayoutId(@LayoutRes int pickerItemLayoutId)

Sets the layout to use for picker items.

`@IdRes int textViewId`	View id of TextView inside a Picker item, or 0 if the Picker item is a TextView.

setSelectedColumn

Added in 1.1.0

public void setSelectedColumn(int columnIndex)

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).

public final void setSeparator(@NonNull CharSequence separator)

Sets separator String between Picker columns.

Parameters
`@NonNull CharSequence separator`	Separator String between Picker columns.

setSeparators

Added in 1.1.0

public final void setSeparators(@NonNull List<CharSequence> separators)

Sets the list of separators that will be populated between the Picker columns. The number of the separators should be either 1 indicating the same separator used between all the columns fields (and nothing will be placed before the first and after the last column), or must be one unit larger than the number of columns passed to setColumns. In the latter case, the list of separators corresponds to the positions before the first column all the way to the position after the last column. An empty string for a given position indicates no separators needs to be placed for that position, otherwise a TextView with the given String will be created and placed there.

Parameters
`@NonNull List<CharSequence> separators`	The list of separators to be populated between the Picker columns.

setVisibleItemCount

Added in 1.1.0

public void setVisibleItemCount(float pickerItems)
