android讀取簡訊多媒體訊息

由於項目需要讀取手機內的簡訊和多媒體訊息資料，不知道如何來處理，本來這個項目是別人做的，後來讓我來修改，都是百度點代碼粘貼上去，一問為啥這樣處理，都是說網上找的代碼，我對我修改後的東西做了下整理，首先感謝http://kaifazhe001.com/article/actueal_-8060143.html這篇部落格，給了我很大的協助，裡面有些東西是看系統源碼來處理的。

會話列表的讀取通過查詢content://mms-sms/conversations?simple=true這個Url可以獲得到，由於裡面有多媒體訊息和簡訊，處理方式如下：

mThreadId = mCursor.getString(ID);    mSnippetCS = mCursor.getLong(SNIPPET_CS);    if(mSnippetCS ==0){    mSnippet = mCursor.getString(SNIPPET);    }    else{    try {    mSnippet = new String(    mCursor.getString(SNIPPET).getBytes("ISO8859_1"), "utf-8");    } catch (UnsupportedEncodingException e) {    // TODO Auto-generated catch block    e.printStackTrace();    }    }

其中mThreadId就是簡訊及多媒體訊息資料庫中所需要的threadid。

點擊某個會話列表進入和某個連絡人所有的聊天記錄時，系統的實現方式是通過查詢url:content://mms-sms/conversations/+會話Id(mThreadId)，查詢的列項不可為空，我試著寫成NULL去查，每次都會出現null 指標異常，源碼內這個參數是：

final String[] PROJECTION = {"transport_type","_id","thread_id","address","body","date","date_sent","read","type","status","locked","error_code","sub","sub_cs","date","date_sent","read","m_type","msg_box","d_rpt","rr","err_type","locked","sim_id","sim_id","service_center","service_center"};

查詢完得到Cursor後，簡訊內容可以直接提取出來，這個簡訊和多媒體訊息的排列是按照日期已經排列好了，但多媒體訊息的內容系統源碼是通過一個pud包來處理的，這個源碼我複製到本地後會用到系統內的.class檔案中的方法，所以只能終止這樣處理，我想是既然這個多媒體訊息和簡訊已經排列好了，而且簡訊的內容已經可以擷取到了，那我直接從多媒體訊息資料庫中讀取多媒體訊息就可以了（content://mms），只要查詢出多媒體訊息資料庫中的id和當前需要的多媒體訊息的id一樣的多媒體訊息就可以了，但這個地方沒有辦法擷取到id（反正我是沒有找到，如果你知道的話，麻煩告訴我一下），所以又終止了。
所以我是先從簡訊資料庫中查詢出threadid和現在的threadid一樣的所有簡訊(content://sms)，然後把date,body,是否為發送的簡訊儲存在一個對象中（我自己定義的類對象），然後把這個Object Storage Service在List<MessageBase> mMessageList中，然後從多媒體訊息資料庫中查詢出threadid和現在的threadid一樣的所有多媒體訊息（content://mms），然後把date, subject, 圖片,是否為發送的多媒體訊息儲存在一個對象中（我自己定義的類對象），然後儲存在mMessageList中，當然多媒體訊息和簡訊對象的類都是繼承自一個基類，然後對mMessageList依據date相進行排序，在這個排序的過程中由於多媒體訊息是以秒來記錄的，而簡訊是以毫秒來記錄的，所以在排序前需要進行1000的縮放，排好序後的mMessageList和手機簡訊中的列表一致了，然後進行顯示，這個顯示是採用一個ListView，重寫Adapter（如上一篇部落格--重寫ListView
Adapter）。
以下是MessageBase的定義：

public class MessageBase {    public long mDate;    public String mThreadId;    public String mId;    public boolean mIsSms;    public boolean mIsInbox;    }

以下是MessageSms的定義：

public class MessageSms extends MessageBase {    public int mType;    public String mBody;    }

以下是MessageMms的定義：

public class MessageSms extends MessageBase {    public int mType;    public String mBody;    }

簡訊中判斷某條簡訊是否為接收的資訊：

messageSms.mType = cursor.getInt(cursor.getColumnIndex("type"));    if(messageSms.mType == 1){    messageSms.mIsInbox = true;    }    else{    messageSms.mIsInbox = false;    }

多媒體訊息中判斷某條多媒體訊息是否為接受的資訊：

messageMms.mType = cursor.getInt(cursor.getColumnIndex("msg_box"));    if(messageSms.mType == 1){    messageMms.mIsInbox = true;    }    else{    messageMms.mIsInbox = false;    }

讀取多媒體訊息內容和多媒體訊息圖片的方法和http://kaifazhe001.com/article/actueal_-8060143.html部落格中寫的一樣，注意其中需要的"mid = ?"這個id是mms中的id，不是threadid。
