推荐答案

@ Mike M的评论是正确的。您正在尝试将日期列的索引转换为日期格式。你实际上并没有转换日期的值。尝试这样：

@Mike M's comment was correct. You're trying to convert the index of the date column to Date format. You're not actually converting the value of the date. Try this:

public void refreshSmsInbox() {

    ContentResolver contentResolver = getContentResolver();
    Cursor smsInboxCursor = contentResolver.query(Uri.parse("content://sms/inbox"), null, null, null, null);

    // get the index of the column
    int indexBody = smsInboxCursor.getColumnIndex("body");
    int indexAddress = smsInboxCursor.getColumnIndex("address");
    int indexDate = smsInboxCursor.getColumnIndex("date");

    if (indexBody < 0 || !smsInboxCursor.moveToFirst()) return;

    // loop through the messages in inbox
    do {
        // get the value based on the index of the column
        String address = smsInboxCursor.getString(indexAddress);
        String body = smsInboxCursor.getString(indexBody);
        long date = smsInboxCursor.getLong(indexDate);

        // convert millis value to proper format
        Date dateVal = new Date(date);
        SimpleDateFormat format = new SimpleDateFormat("dd/MM/yy");
        String dateText = format.format(dateVal);

        String str = address + "\n" + body + "\n" + dateText + "\n";
        System.out.println(str);

    } while (smsInboxCursor.moveToNext());

    smsInboxCursor.close();
}
