Android Development _ Talk about Timepicker (time picker)

Timepicker also inherits from the Framelayout class. The time selection control shows the user the time of day (which can be 24 hours or am/pm) and allows the user to make a selection. If you want to capture events for user-modified time data, you need to add a Ontimechangedlistener listener for Timepicker

First, the method

public int Getbaseline ()

Returns the offset of the text baseline of the window space to its top boundary. If this part does not support baseline alignment, this method returns -1/.

return value

The offset of the baseline, which returns-1 if the baseline alignment is not supported.

Public Integer Getcurrenthour ()

Gets the hour portion of the current time.

return value

Current Hour (0-23)

Public Integer Getcurrentminute ()

Gets the minute portion of the current time.

return value

The current minute.

public boolean Is24hourview ()

Gets whether the current system setting is 24-hour.

return value

Returns true if it is a 24-hour system, otherwise false is returned.

public void Setcurrenthour (Integer currenthour)

Sets the current hour.

public void Setcurrentminute (Integer currentminute)

Sets the current minute (0-59).

public void SetEnabled (Boolean enabled)

Sets the available view state. The interpretation of the available view state is changed in the subclass.

Parameters

Enabled if available is true, otherwise false.

public void Setis24hourview (Boolean is24hourview)

The setting is 24 hours or morning/afternoon.

Parameters

Is24hourview true indicates a 24-hour system. False indicates the morning/afternoon system.

public void Setontimechangedlistener (Timepicker.ontimechangedlistener ontimechangedlistener)

Sets the callback function for the time adjustment event.

Parameters

Ontimechangedlistener callback function, cannot be empty.

Second, example (Global mode)
