android 短信 彩信 数据库 转

短信 sms
文件 /data/data/com.android.providers.telephony/databases/mmssms.db
这个数据库有13张表，sms表存了短信信息。

sms表的uri是        
Java代码
public static final Uri CONTENT_URI = 
            Uri.parse("content://sms"); 

表项含义，我猜的
0 _id
1 thread_id   在短信界面里显示在第几组（ 相同联系人的短信在同意行），英文名叫话题。
2 address   电话好吗
3 person   ? 存在电话簿里的名字 。 可能吧
4 date      日期
5 protocol  ?..
6 read      ?  1- 已读  0-未读 
7 status    ?
8 type      ? 2 我发送
9 reply_path_present   ?
10 subject
11 body      短信内容
12  service_center   ...

好没信息量。。。。

把源码补上。

彩信。

1、pdu表
    mmssms.db库中的pdu表存储了彩信标题、彩信接收时间和彩信ID等信息，其中“_id”是主键，唯一标识了一个条彩信。

2、part表
    mmssms.db库中的part表存储了彩信内容（文本、音乐、图象）的文件名（即上面将的app_parts下面的文件名）、文件类型信息。
    其中“mid”对应着pdu表中的“_id”，“ct”是文件类型，“_data”是存储路径。

3 。 彩信文件读取

      彩信附件文件的地址存储在mmssms.db的part表的_data字段，形如“/data/data/com.android.providers.telephony/app_parts/PART_1262693697763”，但在应用中读取彩信附件时，这个字段基本没什么用，因为不能直接读取这个文件。读取同样要通过ContentProvider，URI为“content://mms/part”，该URI就是对应着part表。可以使用下列代码段来读取文件：
String selection = new String("mid='" + key + "'");//这个key就是pdu里面的_id。
Cursor cur = getContentResolver().query(Uri.parse("content://mms/part"), null, selection, null, null);

        if (cur.moveToFirst())
            do {
                    int _partID = cur.getInt(cur.getColumnIndex("_id"));
                    String partID = String.valueOf(_partID);
                    Uri partURI = Uri.parse("content://mms/part/" + partID);
                   
                    ByteArrayOutputStream baos = new ByteArrayOutputStream();
                    InputStream is = null;

                    try {
                        is = getContentResolver().openInputStream(partURI);
                        byte[] buffer = new byte[256];
                        int len = is.read(buffer);
                        while (len >= 0)
                        {
                            baos.write(buffer, 0, len);
                            len = is.read(buffer);
                        }
                    } catch (IOException e) {
                    } finally {
                        if (is != null) {
                            try {
                                is.close();
                            } catch (IOException e) {

                            }
                        }
                    }
                    }
    这里得到的baos，就是附件文件。
