我正在尝试使用新库来开发带有可穿戴设备（Android Wear）的 Android 应用程序。我了解该库的工作原理，现在我正在尝试为我在本教程中找到的代码开发一个通知，但是当我用一个简单的按钮模拟通知时，它什么也不做，我不知道为什么.. . 我在这里发布我的代码希望你能帮助我理解为什么它不起作用：

public class MainActivity extends Activity {
    private NotificationManager mNotificationManager;
    private int notificationID = 100;
    private int numMessages = 0;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button voiceBtn = (Button) findViewById(R.id.voice);
        voiceBtn.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                voiceNotification();

            }
        });
    }

protected void voiceNotification() {
    // Creo l'istanza di RemoteInput
    final String EXTRA_VOICE_REPLY = "extra_voice_reply";
    String replyLabel = getResources().getString(R.string.reply_label);
    String[] replyChoices = getResources().getStringArray(
            R.array.reply_choices);

    // Creo l'intent
    Intent replyIntent = new Intent(this, ReplyActivity.class);
    PendingIntent replyPendingIntent = PendingIntent.getActivity(this, 0,
            replyIntent, 0);

    // Creo la notifica
    NotificationCompat.Builder replyNotificationBuilder = new NotificationCompat.Builder(
            this);
    replyNotificationBuilder
            .setSmallIcon(android.R.drawable.ic_btn_speak_now);
    replyNotificationBuilder.setContentTitle("Messaggio");
    replyNotificationBuilder.setContentText("Parla ora");
    replyNotificationBuilder.setContentIntent(replyPendingIntent);

    replyNotificationBuilder.setNumber(++numMessages);

    mNotificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);

    mNotificationManager.notify(notificationID,replyNotificationBuilder.build());

     //Creo il remote input
     RemoteInput remoteInput = new RemoteInput.Builder(EXTRA_VOICE_REPLY)
     .setLabel(replyLabel)
     .build();

     // Creo l'azione da associare alla notifica
     Action replyAction = new
     Action.Builder(android.R.drawable.ic_btn_speak_now, "Rispondi",
     replyPendingIntent)
     .addRemoteInput(remoteInput)
     .build();

     // Creo la notifica wearable con il remote input
     Notification replyNotification = new
     WearableNotifications.Builder(replyNotificationBuilder)
     .addAction(replyAction)
     .build();

}

我直接从 Android 开发者页面学习了教程，但它不起作用。我发布的代码有什么问题？

我使用以下代码解决了我的问题：

protected void voiceNotification() {

        // Creo l'intent per l'azione di risposta
        Intent replyIntent = new Intent(this, ReplyActivity.class);

        // Aggiungo l'intent alla coda
        PendingIntent replyPendingIntent = PendingIntent.getActivity(this, 0, replyIntent, 0);

        // Creo la notifica
        NotificationCompat.Builder replyNotificationBuilder = new NotificationCompat.Builder(this);
        replyNotificationBuilder.setSmallIcon(android.R.drawable.ic_btn_speak_now);
        replyNotificationBuilder.setContentTitle("Messaggio");
        replyNotificationBuilder.setContentText("Testo del messaggio");
        replyNotificationBuilder.setContentIntent(replyPendingIntent);
        replyNotificationBuilder.setNumber(++numMessages);
        replyNotificationBuilder.setAutoCancel(true);
        replyNotificationBuilder.setSound(RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION));
        replyNotificationBuilder.setVibrate(new long[]{1000, 1000});
        replyNotificationBuilder.setTicker("Hai una nuova notifica!");

        // Invio la notifica al notification manager
        mNotificationManager = (NotificationManager)getSystemService(Context.NOTIFICATION_SERVICE);
        mNotificationManager.notify(notificationID, replyNotificationBuilder.build());

        // Creo il remote input
        RemoteInput remoteInput = new RemoteInput.Builder(EXTRA_VOICE_REPLY).setLabel(getResources().getString(R.string.reply_label)).build();

        // Creo la notifica compact
        Notification replyNotification = new WearableNotifications.Builder(replyNotificationBuilder).addRemoteInputForContentIntent(remoteInput).build();

        // Passo la notifica appena creata al notification manager compat
        NotificationManagerCompat.from(this).notify(0, replyNotification);
    }

我希望这对其他人有用。
