我想将一些彩信添加到我的设备数据库中。

我有以下代码，但它根本不起作用。没有条目被添加到本机应用程序中......

public static Uri insert(Context context, String[] to, String subject, Uri messageUri)
{
    try
    {
        Uri destUri = Uri.parse("content://mms/sent");

        // Get thread id
        Set<String> recipients = new HashSet<String>();
        recipients.addAll(Arrays.asList(to));
        long thread_id = getOrCreateThreadId(context, recipients);
        Log.e(">>>>>>>", "Thread ID is " + thread_id);

        // Create a dummy sms
        ContentValues dummyValues = new ContentValues();
        dummyValues.put("thread_id", thread_id);
        dummyValues.put("body", "Dummy SMS body.");
        Uri dummySms = context.getContentResolver().insert(Uri.parse("content://sms/sent"), dummyValues);

        // Create a new message entry
        ContentValues mmsValues = new ContentValues();
        mmsValues.put("thread_id", thread_id);
        mmsValues.put("date", System.currentTimeMillis()/1000);
        mmsValues.put("ct_t", "application/vnd.wap.multipart.related");
        mmsValues.put("read", "1");
        mmsValues.put("sub", subject);

        // Create part
        long dummyId = System.currentTimeMillis();
        createPart(context, dummyId, imageBytes);

        // Insert message
        Uri res = context.getContentResolver().insert(destUri, mmsValues);
        String messageId = res.getLastPathSegment().trim();
        Log.e(">>>>>>>", "Message saved as " + res);

        // Update part
        ContentValues updateValues = new ContentValues();
        updateValues.put("mid", messageId);
        Uri updateUri = Uri.parse("content://mms/" + dummyId + "/part");
        int mmsPartRows = context.getContentResolver().update(updateUri, updateValues, null, null);
        Log.e(">>>>>>>", "Part rows " + mmsPartRows);

        // Create addresses
        for (String addr : to)
        {
            ContentValues addrValues = new ContentValues();
            addrValues.put("address", addr);
            addrValues.put("charset", "106");
            addrValues.put("type", 151); // TO
            Uri addrUri = Uri.parse("content://mms/"+ messageId +"/addr");
            Uri mmsAddrUri = context.getContentResolver().insert(addrUri, addrValues);
            Log.e(">>>>>>>", "Addr uri is " + mmsAddrUri.toString());
        }

        res = Uri.parse(destUri + "/" + messageId);

        // Delete dummy sms
        context.getContentResolver().delete(dummySms, null, null);

        return res;
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }

    return null;
}

private static Uri createPart(Context context, long id, byte[] imageBytes) throws Exception
{
    ContentValues mmsPartValue = new ContentValues();
    mmsPartValue.put("ct", "image/png");
    Uri partUri = Uri.parse("content://mms/" + id + "/part");
    Uri res = context.getContentResolver().insert(partUri, mmsPartValue);
    Log.e(">>>>>>>", "Part uri is " + res.toString());

    // Add data to part
    OutputStream os = context.getContentResolver().openOutputStream(res);
    ByteArrayInputStream is = new ByteArrayInputStream(imageBytes);
    byte[] buffer = new byte[256];
    for (int len=0; (len=is.read(buffer)) != -1;)
    {
        os.write(buffer, 0, len);
    }
    os.close();
    is.close();

    return res;
}

private static long getOrCreateThreadId(Context context, String[] numbers)
{
    HashSet<String> recipients = new HashSet<String>();
    recipients.addAll(Arrays.asList(numbers));
    return Telephony.Threads.getOrCreateThreadId(context, recipients);
}
  • context是我的观点上下文
  • to是一个包含地址的字符串数组（例如 new String[] {"0612345678", "0623456789"}）
  • subject是我的彩信主题，例如“通过 MyApp 发送”
  • messageUri是一个指向我想在我的 SD 卡上发送的图像的 Uri。

我做错了吗？

终于我找到了如何做这项工作！这是我制作的代码。

告诉我你是否在这方面遇到了麻烦。

public static Uri insert(Context context, String[] to, String subject, byte[] imageBytes)
{
    try
    {           
        Uri destUri = Uri.parse("content://mms");

        // Get thread id
        Set<String> recipients = new HashSet<String>();
        recipients.addAll(Arrays.asList(to));
        long thread_id = getOrCreateThreadId(context, recipients);
        Log.e(">>>>>>>", "Thread ID is " + thread_id);

        // Create a dummy sms
        ContentValues dummyValues = new ContentValues();
        dummyValues.put("thread_id", thread_id);
        dummyValues.put("body", "Dummy SMS body.");
        Uri dummySms = context.getContentResolver().insert(Uri.parse("content://sms/sent"), dummyValues);

        // Create a new message entry
        long now = System.currentTimeMillis();
        ContentValues mmsValues = new ContentValues();
        mmsValues.put("thread_id", thread_id);
        mmsValues.put("date", now/1000L);
        mmsValues.put("msg_box", MESSAGE_TYPE_OUTBOX);
        //mmsValues.put("m_id", System.currentTimeMillis());
        mmsValues.put("read", 1);
        mmsValues.put("sub", subject);
        mmsValues.put("sub_cs", 106);
        mmsValues.put("ct_t", "application/vnd.wap.multipart.related");
        mmsValues.put("exp", imageBytes.length);
        mmsValues.put("m_cls", "personal");
        mmsValues.put("m_type", 128); // 132 (RETRIEVE CONF) 130 (NOTIF IND) 128 (SEND REQ)
        mmsValues.put("v", 19);
        mmsValues.put("pri", 129);
        mmsValues.put("tr_id", "T"+ Long.toHexString(now));
        mmsValues.put("resp_st", 128);

        // Insert message
        Uri res = context.getContentResolver().insert(destUri, mmsValues);
        String messageId = res.getLastPathSegment().trim();
        Log.e(">>>>>>>", "Message saved as " + res);

        // Create part
        createPart(context, messageId, imageBytes);

        // Create addresses
        for (String addr : to)
        {
            createAddr(context, messageId, addr);
        }

        //res = Uri.parse(destUri + "/" + messageId);

        // Delete dummy sms
        context.getContentResolver().delete(dummySms, null, null);

        return res;
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }

    return null;
}

private static Uri createPart(Context context, String id, byte[] imageBytes) throws Exception
{
    ContentValues mmsPartValue = new ContentValues();
    mmsPartValue.put("mid", id);
    mmsPartValue.put("ct", "image/png");
    mmsPartValue.put("cid", "<" + System.currentTimeMillis() + ">");
    Uri partUri = Uri.parse("content://mms/" + id + "/part");
    Uri res = context.getContentResolver().insert(partUri, mmsPartValue);
    Log.e(">>>>>>>", "Part uri is " + res.toString());

    // Add data to part
    OutputStream os = context.getContentResolver().openOutputStream(res);
    ByteArrayInputStream is = new ByteArrayInputStream(imageBytes);
    byte[] buffer = new byte[256];
    for (int len=0; (len=is.read(buffer)) != -1;)
    {
        os.write(buffer, 0, len);
    }
    os.close();
    is.close();

    return res;
}

private static Uri createAddr(Context context, String id, String addr) throws Exception
{
    ContentValues addrValues = new ContentValues();
    addrValues.put("address", addr);
    addrValues.put("charset", "106");
    addrValues.put("type", 151); // TO
    Uri addrUri = Uri.parse("content://mms/"+ id +"/addr");
    Uri res = context.getContentResolver().insert(addrUri, addrValues);
    Log.e(">>>>>>>", "Addr uri is " + res.toString());

    return res;
}
