android - 内容://sms/address column not always return "sender' s"number

Question

当我查询“content://sms/”内容提供商并从地址栏中提取信息时；我总是得到消息“来自”或“发送到”的电话号码。如果我收到一条消息，那么地址就是对方电话号码。当我发送消息时，地址就是我要发送到的消息。

如何在不查询相应收件箱/已发送文件夹的情况下区分“content://sms/”文件夹中的邮件是已发送邮件还是已接收邮件？

    Uri uri = Uri.parse("content://sms/");
    String[] columns = new String[] { "_id", "thread_id", "address", "person", "date", "body" };
    String selection = "thread_id = " + threadId;
    String sortOrder = "date DESC";
    String limit = "LIMIT " + String.valueOf(mItemsOnPage);

    TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
    String deviceNumber = tm.getLine1Number();

    Cursor cursor = getContentResolver().query(uri, columns, selection, null,
            sortOrder + " " + limit);

    if (cursor != null) {
        cursor.moveToLast();

        while (!cursor.isBeforeFirst()) {
            long messageId = cursor.getLong(0);
            String address = cursor.getString(2);
            long date = cursor.getLong(4);
            String body = cursor.getString(5);
            long person = cursor.getLong(3);
            cursor.moveToPrevious();
        }
    }
    cursor.close();

您需要在查询中包含type列。它包含一个long，指示您正在处理接收的(type == 1)还是发送的(type == 2)消息。

这样您就会知道如何解释地址栏。
