利用contentProvider获取短信内容（SimpleDataFormater的应用）

public static List<SmsInfo> getSmsInfos(Context context){
		// 获取到短信内容提供者的uri
		Uri uri = Uri.parse(path);
		ContentResolver  cr = context.getContentResolver(); 
		
		//_id , address , body ,date ,type 
		List<SmsInfo> smsinfos = new ArrayList<SmsInfo>();
		Cursor cursor = cr.query(uri, new String[]{"_id","address","body","date","type"}, 
				null, 
				null,			
				"date desc");
		
		while(cursor.moveToNext()){
			SmsInfo info = new SmsInfo();
			String address = cursor.getString(cursor.getColumnIndex("address"));
			info.setAddress(address);
			String body = cursor.getString(cursor.getColumnIndex("body"));
			info.setBody(body);
			String date = cursor.getString(cursor.getColumnIndex("date"));
			//定义字符串的日期格式化器 
			SimpleDateFormat dataFormater = new SimpleDateFormat("yyyy-MM-dd hh:mm:ss");
			Date d = new Date(Long.parseLong(date));
			String strdate = dataFormater.format(d);
			info.setDate(strdate);
			String type = cursor.getString(cursor.getColumnIndex("type"));
			if("1".equals(type)){
				info.setType("发送");
			}else if("2".equals(type)){
				info.setType("接受");
			}
			smsinfos.add(info);
			
		}		
		return smsinfos;
