DatePicker和T i m e P i c k er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
spinnersShown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="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <DatePicker android:id="@+id/date_picker" android:layout_width="wrap_content" android:layout_height="320dp" android:layout_marginTop="5dip" android:spinnersShown="false" /> <TimePicker android:id="@+id/time_picker" android:layout_width="wrap_content" android:layout_height="400dp" android:layout_marginTop="5dip" /> </LinearLayout>
JAVA中创建d i a l o g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() { @Override public 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="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <DatePicker android: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() { @Override public 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(); } }
