Java CalendarProvider类使用实例

下面是一个使用Java CalendarProvider类的示例：

import android.content.ContentResolver;import android.content.ContentValues;import android.database.Cursor;import android.net.Uri;import android.provider.CalendarContract;public class CalendarProviderExample {private static final String CALENDAR_NAME = "My Calendar";public static void createCalendar(ContentResolver contentResolver) {ContentValues contentValues = new ContentValues();contentValues.put(CalendarContract.Calendars.ACCOUNT_NAME, "your_account_name");contentValues.put(CalendarContract.Calendars.ACCOUNT_TYPE, "your_account_type");contentValues.put(CalendarContract.Calendars.NAME, CALENDAR_NAME);contentValues.put(CalendarContract.Calendars.CALENDAR_DISPLAY_NAME, CALENDAR_NAME);contentValues.put(CalendarContract.Calendars.CALENDAR_COLOR, 0x00FF00);contentValues.put(CalendarContract.Calendars.CALENDAR_ACCESS_LEVEL, CalendarContract.Calendars.CAL_ACCESS_OWNER);contentValues.put(CalendarContract.Calendars.OWNER_ACCOUNT, "your_owner_account");contentValues.put(CalendarContract.Calendars.VISIBLE, 1);contentValues.put(CalendarContract.Calendars.SYNC_EVENTS, 1);Uri calendarUri = CalendarContract.Calendars.CONTENT_URI;calendarUri = calendarUri.buildUpon().appendQueryParameter(CalendarContract.CALLER_IS_SYNCADAPTER, "true").appendQueryParameter(CalendarContract.Calendars.ACCOUNT_NAME, "your_account_name").appendQueryParameter(CalendarContract.Calendars.ACCOUNT_TYPE, "your_account_type").build();contentResolver.insert(calendarUri, contentValues);}public static void deleteCalendar(ContentResolver contentResolver) {Uri calendarUri = CalendarContract.Calendars.CONTENT_URI;calendarUri = calendarUri.buildUpon().appendQueryParameter(CalendarContract.CALLER_IS_SYNCADAPTER, "true").appendQueryParameter(CalendarContract.Calendars.ACCOUNT_NAME, "your_account_name").appendQueryParameter(CalendarContract.Calendars.ACCOUNT_TYPE, "your_account_type").build();String selection = CalendarContract.Calendars.NAME + "=?";String[] selectionArgs = new String[]{CALENDAR_NAME};contentResolver.delete(calendarUri, selection, selectionArgs);}public static void queryCalendar(ContentResolver contentResolver) {Uri calendarUri = CalendarContract.Calendars.CONTENT_URI;String[] projection = new String[]{CalendarContract.Calendars._ID,CalendarContract.Calendars.ACCOUNT_NAME,CalendarContract.Calendars.ACCOUNT_TYPE,CalendarContract.Calendars.NAME,CalendarContract.Calendars.CALENDAR_DISPLAY_NAME,CalendarContract.Calendars.CALENDAR_COLOR,CalendarContract.Calendars.CALENDAR_ACCESS_LEVEL,CalendarContract.Calendars.OWNER_ACCOUNT,CalendarContract.Calendars.VISIBLE,CalendarContract.Calendars.SYNC_EVENTS};String selection = CalendarContract.Calendars.NAME + "=?";String[] selectionArgs = new String[]{CALENDAR_NAME};Cursor cursor = contentResolver.query(calendarUri, projection, selection, selectionArgs, null);if (cursor != null && cursor.moveToFirst()) {do {long id = cursor.getLong(cursor.getColumnIndex(CalendarContract.Calendars._ID));String accountName = cursor.getString(cursor.getColumnIndex(CalendarContract.Calendars.ACCOUNT_NAME));String accountType = cursor.getString(cursor.getColumnIndex(CalendarContract.Calendars.ACCOUNT_TYPE));String name = cursor.getString(cursor.getColumnIndex(CalendarContract.Calendars.NAME));String displayName = cursor.getString(cursor.getColumnIndex(CalendarContract.Calendars.CALENDAR_DISPLAY_NAME));int color = cursor.getInt(cursor.getColumnIndex(CalendarContract.Calendars.CALENDAR_COLOR));int accessLevel = cursor.getInt(cursor.getColumnIndex(CalendarContract.Calendars.CALENDAR_ACCESS_LEVEL));String ownerAccount = cursor.getString(cursor.getColumnIndex(CalendarContract.Calendars.OWNER_ACCOUNT));int visible = cursor.getInt(cursor.getColumnIndex(CalendarContract.Calendars.VISIBLE));int syncEvents = cursor.getInt(cursor.getColumnIndex(CalendarContract.Calendars.SYNC_EVENTS));// 输出日历信息System.out.println("ID: " + id);System.out.println("Account Name: " + accountName);System.out.println("Account Type: " + accountType);System.out.println("Name: " + name);System.out.println("Display Name: " + displayName);System.out.println("Color: " + color);System.out.println("Access Level: " + accessLevel);System.out.println("Owner Account: " + ownerAccount);System.out.println("Visible: " + visible);System.out.println("Sync Events: " + syncEvents);} while (cursor.moveToNext());cursor.close();}}}

在上面的示例中，我们首先定义了一个常量CALENDAR_NAME，它表示要创建和查询的日历的
