Question

我正在尝试在布局中使用进度条。我不明白为什么它不会渲染。它没有在我的预览中显示，也没有显示我通过实际手机运行应用程序的时间。有什么想法会发生这种情况吗？

这是我的布局XML：

Saab,Volvo,BMW,4E69G-8GNG4-JCZ4Z,H63HQ-VHWPX-ZCJ8J,FKZGK-MXL5C-P2YTE,4E69G-xxxxxx-JCZ4Z,4E69G-AAAxx-JCZ4Z,4E69G-AAAxx-JasasCZ4Z,4E69G-AAAxx-JasaaaasCZ4Z

Answer 1

试试这个，让我知道它是否有效：

$ aws iam list-server-certificates
{
    "ServerCertificateMetadataList": [
        {
            "ServerCertificateId": "ASCAIIMOAKWFL63EKHK4I",
            "ServerCertificateName": "www.ipify.org",
            "Expiration": "2016-05-25T23:59:59Z",
            "Path": "/cloudfront/ipify-www/",
            "Arn": "arn:aws:iam::001177337028:server-certificate/cloudfront/ipify-www/www.ipify.org",
            "UploadDate": "2015-05-26T04:30:15Z"
        },
        {
            "ServerCertificateId": "ASCAJB4VOWIYAWN5UEQAM",
            "ServerCertificateName": "www.rdegges.com",
            "Expiration": "2016-05-28T23:59:59Z",
            "Path": "/cloudfront/rdegges-www/",
            "Arn": "arn:aws:iam::001177337028:server-certificate/cloudfront/rdegges-www/www.rdegges.com",
            "UploadDate": "2015-05-29T00:11:23Z"
        },
        {
            "ServerCertificateId": "ASCAJCH7BQZU5SZZ52YEG",
            "ServerCertificateName": "www.codehappy.io",
            "Expiration": "2016-10-19T23:59:59Z",
            "Path": "/cloudfrount/codehappy-www/",
            "Arn": "arn:aws:iam::001177337028:server-certificate/cloudfrount/codehappy-www/www.codehappy.io",
            "UploadDate": "2015-10-20T20:09:22Z"
        }
    ]
}
