android - 我在 Android 对话的彩信地址字段中的电话号码

Question

我开发了简单的短信/彩信客户端。使用短信一切正常，但使用彩信时我遇到了与对话中的地址字段相关的问题。

我有下一个方法来加载对话。有最后的短信和彩信。

public static List<Conversation> getConversations(Context c) {
    List<Conversation> conversations = new ArrayList<>();
    Conversation conversation;

    Uri uri = Uri.parse("content://mms-sms/conversations/");
    Cursor cursor = c.getContentResolver().query(uri, null, null, null, "normalized_date DESC");

    if (cursor.moveToFirst()) {
        for (int i = 0; i < cursor.getCount(); i++) {
            conversation = new Conversation();
            conversation.setId(cursor.getString(cursor.getColumnIndexOrThrow("_id")));
            conversation.setThreadID(cursor.getString(cursor.getColumnIndexOrThrow("thread_id")));
            conversation.setDate(new Date(Long.valueOf(cursor.getString(cursor.getColumnIndexOrThrow("date")))));
            conversation.setReadType(ReadType.values()[Integer.parseInt(cursor.getString(cursor.getColumnIndexOrThrow("read")))]);
            String type = cursor.getString(cursor.getColumnIndexOrThrow("type"));
            if (isSMS(type)) {
                conversation.setBody(cursor.getString(cursor.getColumnIndexOrThrow("body")));
                conversation.setNumber(cursor.getString(cursor.getColumnIndexOrThrow("address")));
                conversation.setMessageFromType(MessageFromType.values()[Integer.parseInt(type) - 1]);
            } else {
                Map<String, String> mmsContent = getMMSByID(c, conversation.getId());
                conversation.setBody(mmsContent.get("body"));
                conversation.setNumber(mmsContent.get("address"));
            }
            conversations.add(conversation);
            cursor.moveToNext();
        }
    }
    cursor.close();
    return conversations;
}

问题是，当我发送彩信时，我的号码被放入对话的地址字段。有了短信一切都好。所以之后我就不知道谁是我聊天的对手了。

另外我用下一种方式加载彩信号码

private String getNumber(Context c, String mmsdid) {
        String add = "";
        final String[] projection = new String[]{"address", "contact_id"};
        Uri.Builder builder = Uri.parse("content://mms").buildUpon();
        builder.appendPath(String.valueOf(mmsid)).appendPath("addr");
        Cursor cursor = c.getContentResolver().query(
                builder.build(),
                projection,
                null,
                null, null);
        if (cursor.moveToFirst()) {
            add = cursor.getString(cursor.getColumnIndex("address"));
        }
        return add;
    }

也许有人有同样的问题？或者对如何解决有什么建议？

答案很简单，希望对大家有所帮助。一切都很好，除了一个部分。在选择参数中我应该添加

"from=151"

或

"from="+PduHeaders.TO

所以代码看起来像这样:

private static String getNumber(Context c, String id) {
        String add = "";
        final String[] projection = new String[]{"address"};
        Uri.Builder builder = Uri.parse("content://mms").buildUpon();
        builder.appendPath(String.valueOf(id)).appendPath("addr");
        Cursor cursor = c.getContentResolver().query(
                builder.build(),
                projection,
                "type="+PduHeaders.TO,
                null, null);
        if (cursor.moveToFirst()) {
            add = cursor.getString(cursor.getColumnIndex("address"));
        }
        cursor.close();
        return add;
    }
