Class NumberPicker

java.lang.Object
  android.view.View
      android.view.ViewGroup
          android.widget.LinearLayout
              net.simonvt.numberpicker.NumberPicker

All Implemented Interfaces:: android.graphics.drawable.Drawable.Callback, android.view.accessibility.AccessibilityEventSource, android.view.KeyEvent.Callback, android.view.ViewManager, android.view.ViewParent

public class NumberPicker
extends android.widget.LinearLayout
extends android.widget.LinearLayout

A widget that enables the user to select a number form a predefined range. There are two flavors of this widget and which one is presented to the user depends on the current theme.

If the current theme is derived from R.style.Theme the widget presents the current value as an editable input field with an increment button above and a decrement button below. Long pressing the buttons allows for a quick change of the current value. Tapping on the input field allows to type in a desired value.
If the current theme is derived from R.style.Theme_Holo or R.style.Theme_Holo_Light the widget presents the current value as an editable input field with a lesser value above and a greater value below. Tapping on the lesser or greater value selects it by animating the number axis up or down to make the chosen value current. Flinging up or down allows for multiple increments or decrements of the current value. Long pressing on the lesser and greater values also allows for a quick change of the current value. Tapping on the current value allows to type in a desired value.

For an example of using this widget, see TimePicker.

Nested Class Summary
`static class`	`NumberPicker.CustomEditText`
`static interface`	`NumberPicker.Formatter` Interface used to format current value into a string for presentation.
`static interface`	`NumberPicker.OnScrollListener` Interface to listen for the picker scroll state.
`static interface`	`NumberPicker.OnValueChangeListener` Interface to listen for changes of the current value.

getSolidColor

public int getSolidColor()

Overrides:: getSolidColor in class android.view.View

setOnValueChangedListener

public void setOnValueChangedListener(NumberPicker.OnValueChangeListener onValueChangedListener)

Sets the listener to be notified on change of the current value.

Parameters:: onValueChangedListener - The listener.

setOnScrollListener

public void setOnScrollListener(NumberPicker.OnScrollListener onScrollListener)

Set listener to be notified for scroll state changes.

Parameters:: onScrollListener - The listener.

setFormatter

public void setFormatter(NumberPicker.Formatter formatter)

Set the formatter to be used for formatting the current value.

Note: If you have provided alternative values for the values this formatter is never invoked.

Parameters:: formatter - The formatter object. If formatter is null, String.valueOf(int) will be used.
See Also:: setDisplayedValues(String[])

setValue

public void setValue(int value)

Set the current value for the number picker.

If the argument is less than the getMinValue() and getWrapSelectorWheel() is false the current value is set to the getMinValue() value.

If the argument is less than the getMinValue() and getWrapSelectorWheel() is true the current value is set to the getMaxValue() value.

If the argument is less than the getMaxValue() and getWrapSelectorWheel() is false the current value is set to the getMaxValue() value.

If the argument is less than the getMaxValue() and getWrapSelectorWheel() is true the current value is set to the getMinValue() value.

Parameters:: value - The current value.
See Also:: setWrapSelectorWheel(boolean), setMinValue(int), setMaxValue(int)

getWrapSelectorWheel

public boolean getWrapSelectorWheel()

Gets whether the selector wheel wraps when reaching the min/max value.

Returns:: True if the selector wheel wraps.
See Also:: getMinValue(), getMaxValue()

setWrapSelectorWheel

public void setWrapSelectorWheel(boolean wrapSelectorWheel)

Sets whether the selector wheel shown during flinging/scrolling should wrap around the getMinValue() and getMaxValue() values.

By default if the range (max - min) is more than the number of items shown on the selector wheel the selector wheel wrapping is enabled.

Note: If the number of items, i.e. the range ( getMaxValue() - getMinValue()) is less than the number of items shown on the selector wheel, the selector wheel will not wrap. Hence, in such a case calling this method is a NOP.

Parameters:: wrapSelectorWheel - Whether to wrap.

setOnLongPressUpdateInterval

public void setOnLongPressUpdateInterval(long intervalMillis)

Sets the speed at which the numbers be incremented and decremented when the up and down buttons are long pressed respectively.

The default value is 300 ms.

Parameters:: intervalMillis - The speed (in milliseconds) at which the numbers will be incremented and decremented.

getValue

public int getValue()

Returns the value of the picker.

Returns:: The value.

getMinValue

public int getMinValue()

Returns the min value of the picker.

Returns:: The min value

setMinValue

public void setMinValue(int minValue)

Sets the min value of the picker.

Parameters:: minValue - The min value inclusive. Note: The length of the displayed values array set via setDisplayedValues(String[]) must be equal to the range of selectable numbers which is equal to getMaxValue() - getMinValue() + 1.

getMaxValue

public int getMaxValue()

Returns the max value of the picker.

Returns:: The max value.

setMaxValue

public void setMaxValue(int maxValue)

Sets the max value of the picker.

Parameters:: maxValue - The max value inclusive. Note: The length of the displayed values array set via setDisplayedValues(String[]) must be equal to the range of selectable numbers which is equal to getMaxValue() - getMinValue() + 1.

getDisplayedValues

public String[] getDisplayedValues()

Gets the values to be displayed instead of string values.

Returns:: The displayed values.

setDisplayedValues

public void setDisplayedValues(String[] displayedValues)

Sets the values to be displayed.

Parameters:: displayedValues - The displayed values. Note: The length of the displayed values array must be equal to the range of selectable numbers which is equal to getMaxValue() - getMinValue() + 1.

getTopFadingEdgeStrength

protected float getTopFadingEdgeStrength()

Overrides:: getTopFadingEdgeStrength in class android.view.View

getBottomFadingEdgeStrength

protected float getBottomFadingEdgeStrength()

Overrides:: getBottomFadingEdgeStrength in class android.view.View

onDetachedFromWindow

protected void onDetachedFromWindow()

Overrides:: onDetachedFromWindow in class android.view.View

onDraw

protected void onDraw(android.graphics.Canvas canvas)

Overrides:: onDraw in class android.widget.LinearLayout

onInitializeAccessibilityEvent

Overrides:: getAccessibilityNodeProvider in class android.view.View

resolveSizeAndState

public static int resolveSizeAndState(int size,
                                      int measureSpec,
                                      int childMeasuredState)

Utility to reconcile a desired size and state, with constraints imposed by a MeasureSpec. Will take the desired size, unless a different size is imposed by the constraints. The returned value is a compound integer, with the resolved size in the View.MEASURED_SIZE_MASK bits and optionally the bit View.MEASURED_STATE_TOO_SMALL set if the resulting size is smaller than the size the view wants to be.

Parameters:: size - How big the view wants to be; measureSpec - Constraints imposed by the parent
Returns:: Size information bit mask as defined by View.MEASURED_SIZE_MASK and View.MEASURED_STATE_TOO_SMALL.
