DatePickerDatePickerDatePicker和TimePickerTimePickerTimePicker是安卓自带的日期选择器，可以变换多种样式，下面是他们的简单使用。
显示年月日和具体时间
spinnersShownspinnersShownspinnersShown设置是否显示Spinner日期选择组件
dialog_time.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="/apk/res/android"android:orientation="vertical"android:layout_width="match_parent"android:layout_height="match_parent"><DatePickerandroid:id="@+id/date_picker"android:layout_width="wrap_content"android:layout_height="320dp"android:layout_marginTop="5dip"android:spinnersShown="false" /><TimePickerandroid:id="@+id/time_picker"android:layout_width="wrap_content"android:layout_height="400dp"android:layout_marginTop="5dip" /></LinearLayout>
JAVA中创建dialogdialogdialog选择日期
private void showTime() {AlertDialog.Builder builder = new AlertDialog.Builder(getContext());View view = View.inflate(getContext(), R.layout.dialog_time, null);final DatePicker datePicker = (DatePicker) view.findViewById(R.id.date_picker);final TimePicker timePicker = (android.widget.TimePicker) view.findViewById(R.id.time_picker);builder.setView(view);Calendar cal = Calendar.getInstance();cal.setTimeInMillis(System.currentTimeMillis());datePicker.init(cal.get(Calendar.YEAR), cal.get(Calendar.MONTH), cal.get(Calendar.DAY_OF_MONTH), null);timePicker.setIs24HourView(true);timePicker.setCurrentHour(cal.get(Calendar.HOUR_OF_DAY));timePicker.setCurrentMinute(Calendar.MINUTE);builder.setPositiveButton("确 定", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {String CurrentHour=timePicker.getCurrentHour().toString();String CurrentMinute=timePicker.getCurrentMinute().toString();if (timePicker.getCurrentHour() >= 0 && timePicker.getCurrentHour() <= 9) {CurrentHour = "0" + timePicker.getCurrentHour() ;}if (timePicker.getCurrentMinute() >= 0 && timePicker.getCurrentMinute() <= 9) {CurrentMinute = "0" + timePicker.getCurrentMinute();}StringBuffer sb = new StringBuffer();sb.append(String.format("%d年%02d月%02d日",datePicker.getYear(),datePicker.getMonth() + 1,datePicker.getDayOfMonth()));sb.append(" ");sb.append(CurrentHour).append(":").append(CurrentMinute).append(":00");ttime=sb.toString();System.out.println(ttime);dialog.cancel();//取消dialog}});Dialog dialog = builder.create();dialog.show();}
只显示年月
dialog_his.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="/apk/res/android"android:orientation="vertical"android:layout_width="match_parent"android:layout_height="match_parent"><DatePickerandroid:id="@+id/date_picker_his"android:layout_width="wrap_content"android:layout_height="320dp"android:layout_marginTop="5dip"android:calendarViewShown="false"android:datePickerMode="spinner" /></LinearLayout>
JAVA
private void show() {System.out.println("点击了日历");AlertDialog.Builder builder = new AlertDialog.Builder(this);View view = View.inflate(this, R.layout.dialog_his, null);final DatePicker datePicker = (DatePicker) view.findViewById(R.id.date_picker_his);builder.setView(view);Calendar cal = Calendar.getInstance();cal.setTimeInMillis(System.currentTimeMillis());datePicker.init(cal.get(Calendar.YEAR), cal.get(Calendar.MONTH), cal.get(Calendar.DAY_OF_MONTH), null);hideDay(datePicker);builder.setPositiveButton("确 定", new DialogInterface.OnClickListener() {@Overridepublic void onClick(DialogInterface dialog, int which) {year=datePicker.getYear();month=datePicker.getMonth()+1;ShowData();System.out.println(year+"年"+month+"月");dialog.cancel();//取消dialog}});Dialog dialog = builder.create();dialog.show();}private void hideDay(DatePicker mDatePicker) {try {/* 处理android5.0以上的特殊情况 */if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {int daySpinnerId = Resources.getSystem().getIdentifier("day", "id", "android");if (daySpinnerId != 0) {View daySpinner = mDatePicker.findViewById(daySpinnerId);if (daySpinner != null) {daySpinner.setVisibility(View.GONE);}}} else {Field[] datePickerfFields = mDatePicker.getClass().getDeclaredFields();for (Field datePickerField : datePickerfFields) {if ("mDaySpinner".equals(datePickerField.getName()) || ("mDayPicker").equals(datePickerField.getName())) {datePickerField.setAccessible(true);Object dayPicker = new Object();try {dayPicker = datePickerField.get(mDatePicker);} catch (IllegalAccessException e) {e.printStackTrace();} catch (IllegalArgumentException e) {e.printStackTrace();}((View) dayPicker).setVisibility(View.GONE);}}}} catch (Exception e) {e.printStackTrace();}}
