I. Overview

Scrolling time selection now seems very common, so summarize, show the effect of general, do a reference it!

Above is, you can scroll to select the date and time, because it is operating in the 5.0 system, it seems that the 5.0 system has made changes, the following "Cancel", "OK" default will not be centered display, I do not know how to let it center display, but under 5.0 system operation by default is centered display.

Two. layout files

<?XML version= "1.0" encoding= "Utf-8"?><LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent"android:orientation= "vertical"android:padding= "10dip" >    <TimepickerAndroid:timepickermode= "Spinner"Android:id= "@+id/time_picker"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:layout_margintop= "5dip"android:layout_gravity= "Center" >    </Timepicker></LinearLayout>

The above is the time selection of the layout file, very simple, but need to pay attention to a little

Android:timepickermode= "Spinner" if not added to this sentence, under 5.0 the system runs completely without any problems, but in more than 5.0 of the system runs the discovery time layout becomes a round clock, so if you do not want to display the clock, you need to add this sentence!

<?XML version= "1.0" encoding= "Utf-8"?><LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent"android:orientation= "vertical"android:padding= "10dip" >    <DatePickerAndroid:datepickermode= "Spinner"Android:calendarviewshown= "false"Android:id= "@+id/date_picker"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:layout_margintop= "5dip"android:layout_gravity= "Center" >    </DatePicker></LinearLayout>

The above is the date selection layout, the same

Android:datepickermode= "Spinner" android:calendarviewshown= "false"
These 2 words are to avoid more than 5.0 of the system running "Calendar Style", if you remove these 2 words, will become a calendar style, 5.0 The following system can remove/retain the 2 sentences

Show ();    }        }); }

The code is simple, just add a click event to the date and time Button in the activity.

Datebtn.setonclicklistener (SetDate ());

Timebtn.setonclicklistener (SetTime ());
