Question

我正在尝试使用此代码在按钮上发布通知：

public void onClick(View v) {
        NotificationCompat.Builder mBuilder =
                new NotificationCompat.Builder(this)
                .setSmallIcon(R.drawable.ic_launcher)
                .setContentTitle("My notification")
                .setContentText("Hello World!");
        // Creates an explicit intent for an Activity in your app
        Intent resultIntent = new Intent(this, MainActivity.class);

        // The stack builder object will contain an artificial back stack for the
        // started Activity.
        // This ensures that navigating backward from the Activity leads out of
        // your application to the Home screen.
        TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
        // Adds the back stack for the Intent (but not the Intent itself)
        stackBuilder.addParentStack(MainActivity.class);
        // Adds the Intent that starts the Activity to the top of the stack
        stackBuilder.addNextIntent(resultIntent);
        PendingIntent resultPendingIntent =
                stackBuilder.getPendingIntent(
                    0,
                    PendingIntent.FLAG_UPDATE_CURRENT
                );
        mBuilder.setContentIntent(resultPendingIntent);
        NotificationManager mNotificationManager =
            (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
        // mId allows you to update the notification later on.
        i = (int) Math.random();
        mNotificationManager.notify(i, mBuilder.build());
    }

我知道.notfiy（id，通知）允许它只发布一个具有相同ID的通知，但只是为了这个示例应用程序我希望能够发布通知，即使它是相同的一。这就是为什么我试图使用一个随机数，所以它会切换id，但这仍然没有帮助。有什么建议吗？

顺便说一下，这是发布通知的方式，但只有一个通知，直到我清除它

使用全局int＆＃39; i = 0＆＃39;并在每次创建通知后增加它并更改代码，如下所示

public void onClick(View v) {
    NotificationCompat.Builder mBuilder =
            new NotificationCompat.Builder(this)
            .setSmallIcon(R.drawable.ic_launcher)
            .setContentTitle("My notification")
            .setContentText("Hello World!");
    // Creates an explicit intent for an Activity in your app
    Intent resultIntent = new Intent(this, MainActivity.class);

    // The stack builder object will contain an artificial back stack for the
    // started Activity.
    // This ensures that navigating backward from the Activity leads out of
    // your application to the Home screen.
    TaskStackBuilder stackBuilder = TaskStackBuilder.create(this);
    // Adds the back stack for the Intent (but not the Intent itself)
    stackBuilder.addParentStack(MainActivity.class);
    // Adds the Intent that starts the Activity to the top of the stack
    stackBuilder.addNextIntent(resultIntent);
i++;
 PendingIntent resultPendingIntent =
            stackBuilder.getPendingIntent(
                i,
                PendingIntent.FLAG_UPDATE_CURRENT
            );
    mBuilder.setContentIntent(resultPendingIntent);
    NotificationManager mNotificationManager =
        (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
    // mId allows you to update the notification later on.

    mNotificationManager.notify(i, mBuilder.build());
}

希望这能解决问题

继续发布相同的通知
