小编Lea*_*Bun的帖子

我想在ASP.NET(C#)中将一些结果写入控制台.它适用于Window应用程序,但Web应用程序不起作用.这是我尝试过的:

protected void btonClick_Click(object sender, EventArgs e)
{
    Console.WriteLine("You click me ...................");
    System.Diagnostics.Debug.WriteLine("You click me ..................");
    System.Diagnostics.Trace.WriteLine("You click me ..................");
}

但我在"输出"面板中看不到任何内容.我该如何解决这个问题？

我正在创建一个音乐播放器应用程序 我想在我的应用程序在后台运行时在通知栏上显示媒体控制器.它看起来像谷歌播放器.

这该怎么做？

我有一个"产品"自定义帖子类型.通常,此自定义帖子类型具有"添加新"按钮.我想添加另一个按钮调用"从提供商更新".

目前,我已修改Wordpress代码(在"wordpress\wp-admin\includes\class-wp-list-table.php"中)以添加该按钮.在这种情况下,当我更新Wordpress时,我的修改后的代码将被删除.因此,我需要将该按钮移动到我的插件代码中.

在这种情况下,请帮助我如何将该按钮移动到我的插件代码.

我正在创建一个可以从服务器下载文件并在状态栏中显示进度的应用程序。这是我的代码：

private void startDownload(final String fileUrl) {
    Thread thread = new Thread() {
        @Override
        public void run() {
            NotificationManagerCompat notificationManagerCompat = NotificationManagerCompat.from(DownloadsActivity.this);

            String contentTitle = "Start downloading";
            Intent notifyIntent = new Intent();
            PendingIntent notifyPendingIntent = PendingIntent.getActivity(DownloadsActivity.this, DOWNLOAD_NOTIFICATION_ID, notifyIntent, PendingIntent.FLAG_UPDATE_CURRENT);

            NotificationCompat.Builder notificationBuilder = createNotificationBuilder("downloader_channel");
            notificationBuilder.setContentIntent(notifyPendingIntent);
            notificationBuilder.setTicker("Start downloading from the server");
            notificationBuilder.setOngoing(true);
            notificationBuilder.setAutoCancel(false);
            notificationBuilder.setSmallIcon(android.R.drawable.stat_sys_download);
            notificationBuilder.setContentTitle(contentTitle);
            notificationBuilder.setContentText("0%");
            notificationBuilder.setProgress(100, 0, false);
            notificationManagerCompat.notify(DOWNLOAD_NOTIFICATION_ID, notificationBuilder.build());

            boolean success;
            try {
                String fileName = DownloadUtils.getInstance().getFullFileName(fileUrl);
                File tmpFile = new File(fileName + ".tmp");

                URL url = new URL(fileUrl);
                URLConnection …

我正在开发一个总是从用户那里收听语音的Android应用程序.它在Sony X10i上运行时有效,但在三星Galaxy SII中不起作用.这是我的代码:

    SpeechRecognizer     speechRecognizer;
    speechRecognizer = SpeechRecognizer.createSpeechRecognizer(getBaseContext());
    MyRecognitionListener speechListner=new MyRecognitionListener();
    speechRecognizer.setRecognitionListener(speechListner);
    speechRecognizer.startListening(RecognizerIntent.getVoiceDetailsIntent(getApplicationContext()));

这是我的听众课程:

class MyRecognitionListener implements RecognitionListener {

    public void onBeginningOfSpeech() {
        Log.d("leapkh", "onBeginningOfSpeech");
    }

    public void onBufferReceived(byte[] buffer) {
        Log.d("leapkh", "onBufferReceived");
    }

    public void onEndOfSpeech() {
        Log.d("leapkh", "onEndOfSpeech");
    }

    public void onError(int error) {
        Log.d("leapkh", "onError");
    }

    public void onEvent(int eventType, Bundle params) {
        Log.d("leapkh", "onEvent");
    }

    public void onPartialResults(Bundle partialResults) {
        Log.d("leapkh", "onPartialResults");
    }

    public void onReadyForSpeech(Bundle params) {
        Log.d("leapkh", "onReadyForSpeech");
    }


    public void onResults(Bundle results) { …

我正在使用MobileVLCKit库中的VLCMediaPlayer类来制作音频流应用程序.我的问题是,当发生错误时(例如,错误的流URL),它会自动警告自己的错误消息.在我的情况下,我想禁用该警报消息并显示我自己的消息.

我正在尝试使用 ListTiles 作为水平 ListView 的项目。

final brandsWidget = SizedBox(
  height: 200,
  child: ListView(
    scrollDirection: Axis.horizontal,
    children: [
      ListTile(
        leading: Image.asset('img_1.png'),
        title: Text('Product 1'),
        subtitle: Text('\$5'),
      ),
      ListTile(
        leading: Image.asset('img_1.png),
        title: Text('Product 2'),
        subtitle: Text('\$3'),
      )
    ],
  ),
);

我收到以下错误：

Another exception was thrown: BoxConstraints forces an infinite width.
Exception caught by rendering library.
BoxConstraints forces an infinite width.
The relevant error-causing widget was ListTile 

我正在使用ASP.Net MVC和ADO.Net实体数据模型.当我使用ToList()方法时,它从表中选择所有记录.

userEntity.USERs.ToList();

在这种情况下,我可以在SQL语句中排除类似"where"子句的特定记录吗？谢谢!

我正在开发一个使用twitter4j API与Twitter交互的应用程序.此API是否为直接消息提供了事件监听器？
