setOnClickListener

public void setOnClickListener(android.view.View.OnClickListener onClickListener)

Set listener to be notified on click of the current value.

Overrides:

setOnClickListener in class android.view.View

Parameters:

onClickListener - The listener.

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

                                      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.
