Question

我想获得一个int，其中包含设备帐户中未读电子邮件的数量。我已经看到有一种新方法可以使用＆＃34; Gmail标签公共API＆＃34;

我已阅读文档并下载了示例应用程序，它确实有效。但我有两个问题：（

我的目的是获得一个未读会话数量的int，我试试这个：

 public static int getUnreadGmailCount(Context context) {

    ContentResolver cr = context.getContentResolver();
    Cursor cursor = cr.query(GmailContract.Labels.getLabelsUri("ensisinfo102@gmail.com"),
            null,
            null, null,
            null);
    if (cursor == null || cursor.isAfterLast()) {
        Log.d(TAG, "No Gmail inbox information found for account.");
        if (cursor != null) {
            cursor.close();
        }
        return 0;
    }
    int count = 0;
    while (cursor.moveToNext()) {
        if (CANONICAL_NAME_INBOX_CATEGORY_PRIMARY.equals(cursor.getString(cursor.getColumnIndex(CANONICAL_NAME)))) {
            count = cursor.getInt(cursor.getColumnIndex(NUM_UNREAD_CONVERSATIONS));
            System.out.println("count is====>"+count);
            break;
        }
    }
    cursor.close();
    return count;
}

但不起作用，总是返回＆＃34; 0＆＃34;，但在gmail中我有3条未读消息

非常感谢任何帮助

感谢和问候

Answer 1

您可以get a label并查看<div class="container"> <div class="tooltip">Shorter text <span class="tooltiptext">A short tooltip.</span> </div> </div> <div class="container"> <div class="tooltip">Longer text <span class="tooltiptext">When I try to make it work with longer text in the tooltip, I can't make it look good. Either I have to specify a fixed width or min-width for the tooltip, which makes it look decent for longer texts but awful for short ones, or I don't, and the longer text only expands vertically, assuming the lowest possible width without overflow. <br /> <br /> Also, the positioning doesn't work well with tooltips spanning multiple lines.</span> </div> </div>。 messagesUnread标签可能是您想要的：
