本文给大家分享的是一段使用java制作Android日历的代码，非常简单实用，实现了读取日历事件、插入事件、编辑日历事件、查看日历等功能，有需要的小伙伴参考下

代码很简单，就不多废话了

复制代码代码如下:

	
	//读取日历事件

	    public static void getCalendarInfo(Activity activity,String tag){

	        String[] projection = new String[]{CalendarContract.Events._ID,CalendarContract.Events.TITLE};

	        ContentResolver cr = activity.getContentResolver();

	        Cursor cursor = cr.query(CalendarContract.Events.CONTENT_URI, projection, null, null, null);

	        int idIndex = cursor.getColumnIndexOrThrow(CalendarContract.Events._ID);

	        Log.d(tag, cursor.getCount()+"");

	        int titleIndex = cursor.getColumnIndexOrThrow(CalendarContract.Events.TITLE);

	        while (cursor.moveToNext()) {

	            String id = cursor.getString(idIndex);

	            String title = cursor.getString(titleIndex);

	            Log.d(tag, id+":"+title);

	        }

	        cursor.close();

	    }

	    //插入事件

	    public static void addCalendarEvent(Activity activity,String tag){

	        Intent intent = new Intent(Intent.ACTION_INSERT,CalendarContract.Events.CONTENT_URI);

	        Log.d(tag, CalendarContract.Events.CONTENT_URI.toString());

	        intent.putExtra(CalendarContract.Events.TITLE, "Launch");

	        intent.putExtra(CalendarContract.Events.DESCRIPTION, "Launch,Android app");

	        intent.putExtra(CalendarContract.Events.EVENT_LOCATION, "baidu.com");

	        Calendar calendar = Calendar.getInstance();

	        calendar.setTime(new Date());

	        intent.putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, calendar.getTimeInMillis());

	        intent.putExtra(CalendarContract.EXTRA_EVENT_ALL_DAY, true);

	        activity.startActivity(intent);

	    }

	    //编辑日历事件

	    public static void editCalendarEvent(Activity activity,String tag){

	        long rowId = 1;

	        Uri editUri = ContentUris.withAppendedId(CalendarContract.Events.CONTENT_URI,rowId);

	        Log.d(tag, CalendarContract.Events.CONTENT_URI.toString());

	        Intent intent = new Intent(Intent.ACTION_EDIT,editUri);

	        intent.putExtra(CalendarContract.Events.EVENT_LOCATION, "NJ");

	        Calendar calendar = Calendar.getInstance();

	        calendar.set(2015, 2, 17, 12, 1, 1);

	        intent.putExtra(CalendarContract.EXTRA_EVENT_BEGIN_TIME, calendar.getTimeInMillis());

	        intent.putExtra(CalendarContract.EXTRA_EVENT_ALL_DAY, true);

	        activity.startActivity(intent);

	    }

	    //查看日历

	    public static void viewCalendar(Activity activity,String tag){

	        Calendar calendar = Calendar.getInstance();

	        calendar.set(2015, 2, 17, 12, 1, 1);

	        Uri uri = Uri.parse("content://com.android.calendar/time/"+calendar.getTimeInMillis());

	        Intent intent = new Intent(Intent.ACTION_VIEW,uri);

	        activity.startActivity(intent);

	    }
