Titanium.UI.Picker

A control used to select one or more fixed values.

Android	iOS

Use the Titanium.UI.createPicker method or Alloy <Picker> element to create a picker control.

On Android, the useSpinner property must be enabled to support multiple columns. By default, the spinner is automatically sized to fit its content and can overflow to additional spinner rows. The size of the picker can be adjusted with the width and height properties, but may omit picker columns or cut off picker rows if the size is set too small. This property is deprecated. Please use the default Android native "dropdown" style by not setting useSpinner to true.

On iOS, the height property is only available in iOS 9 and later. By default, the size of the picker, including its background, is fixed at the same height as the iPhone keyboard to respect the iOS Human Interface Guidelines. The default width on iOS is 320px and the height is 228px. The contents of the picker are sized to fit the picker, which may cut off text in the picker rows. Adding views to picker rows is also supported on iOS.

On iPad, Apple recommends using a picker only in a popover. Since the size of the picker cannot be adjusted, it is not suitable for the main screen.

Note: you can only set the columns property for the plain picker. If you set the type property to anything else except Titanium.UI.PICKER_TYPE_PLAIN, you cannot modify the picker's columns.

Properties #

accessibilityDisableLongPress#

extendedcreation only

Type: Boolean

Boolean value to remove the long press notification for the device's accessibility service.

Will disable the "double tap and hold for long press" message when selecting an item.

accessibilityHidden#

extended

Type: Boolean

Whether the view should be "hidden" from (i.e., ignored by) the accessibility service.

On iOS this is a direct analog of the accessibilityElementsHidden property defined in the
UIAccessibility Protocol.

On Android, setting accessibilityHidden calls the native
View.setImportantForAccessibility
method. The native method is only available in Android 4.1 (API level 16/Jelly Bean) and
later; if this property is specified on earlier versions of Android, it is ignored.

accessibilityHint#

extended

Type: String

Briefly describes what performing an action (such as a click) on the view will do.

On iOS this is a direct analog of the accessibilityHint property defined in the
UIAccessibility Protocol.
On Android, it is concatenated together with
Titanium.UI.View.accessibilityLabel and Titanium.UI.View.accessibilityValue in the order: accessibilityLabel,
accessibilityValue, accessibilityHint. The concatenated value is then passed as the
argument to the native View.setContentDescription method.

accessibilityLabel#

extended

Type: String

A succinct label identifying the view for the device's accessibility service.

On iOS this is a direct analog of the accessibilityLabel property defined in the
UIAccessibility Protocol.
On Android, it is concatenated together with
Titanium.UI.View.accessibilityValue and Titanium.UI.View.accessibilityHint in the order: accessibilityLabel,
accessibilityValue, accessibilityHint. The concatenated value is then passed as the
argument to the native View.setContentDescription method.
Defaults to Title or label of the control.

accessibilityValue#

extended

Type: String

A string describing the value (if any) of the view for the device's accessibility service.

On iOS this is a direct analog of the accessibilityValue property defined in the
UIAccessibility Protocol.
On Android, it is concatenated together with
Titanium.UI.View.accessibilityLabel and Titanium.UI.View.accessibilityHint in the order: accessibilityLabel,
accessibilityValue, accessibilityHint. The concatenated value is then passed as the
argument to the native View.setContentDescription method.
Defaults to State or value of the control.

animatedCenter#

extended

Type: Point

Current position of the view during an animation.

apiName#

extended

Type: String

The name of the API that this proxy corresponds to.

The value of this property is the fully qualified name of the API. For example, Button
returns Ti.UI.Button.

backgroundColor#

Type: String, Titanium.UI.Color

Background color of the picker, as a color name or hex triplet.

For information about color values, see the "Colors" section of Titanium.UI.

Android: If you want to change the backgroundColor you have to set the borderStyle to
Ti.UI.INPUT_BORDERSTYLE_ROUNDED or Ti.UI.INPUT_BORDERSTYLE_NONE

borderColor#

extended

Type: String, Titanium.UI.Color

Border color of the view, as a color name or hex triplet.

For information about color values, see the "Colors" section of Titanium.UI.

Defaults to the normal background color of this view (Android), black (iOS).

borderRadius#

extended

Type: Number, String, Array<Number>, Array<String>

Radius for the rounded corners of the view's border.

Each corner is rounded using an arc of a circle.
Values for each corner can be specified. For example, '20px 20px' will set both left and right corners to 20px.
Specifying '20px 20px 20px 20px' will set top-left, top-right, bottom-right and bottom-left corners in that order.

If you have issues with dark artifacts on Android you can try to disable Hardware acceleration by setting a
backgroundColor with a small amount of transparency: backgroundColor:"rgba(255,255,255,254)".

borderStyle#

creation only

Type: Number

Border style to use when picker is shown as a text field or drop-down field.

This is an Android only property which only applies to pickers of type:

PICKER_TYPE_DATE or PICKER_TYPE_TIME
that also have datePickerStyle set to
DATE_PICKER_STYLE_COMPACT.
PICKER_TYPE_PLAIN that also have property
useSpinner set false to show a drop-down picker.

borderWidth#

will be changed to 1 of the unit declared as 'ti.ui.defaultunit' in tiapp.xml descriptor.

bottom#

extended

Type: Number, String

View's bottom position, in platform-specific units.

This position is relative to the view's parent. Exact interpretation depends on the parent
view's layout property. Can be either a float value or a
dimension string (for example, '50%' or '10px').

This is an input property for specifying where the view should be positioned, and does not
represent the view's calculated position.

Defaults to undefined.

bubbleParent#

extended

Type: Boolean

Indicates if the proxy will bubble an event to its parent.

Some proxies (most commonly views) have a relationship to other proxies, often
established by the add() method. For example, for a button added to a window, a
click event on the button would bubble up to the window. Other common parents are
table sections to their rows, table views to their sections, and scrollable views
to their views. Set this property to false to disable the bubbling to the proxy's parent.

calendarViewShown#

Type: Boolean

Determines whether the calenderView is visible.

If 'calendarViewShown' is 'true', the calenderView is visible

Methods #

add #

Adds rows or columns to the picker.

Once you use this method to add rows and columns to a picker, you cannot remove or
manipulate them.

Parameters:

Name	Type	Summary	Optional
`data`	`Array<Titanium.UI.PickerRow>, Titanium.UI.PickerRow, Array<Titanium.UI.PickerColumn>, Titanium.UI.PickerColumn`	A row, set of rows, a column of rows or a set of columns of rows. When this method is used to add a row or set of rows, a single-column picker is created.	No
