Question

我使用此代码在我的应用中显示通知。因为我运行API 16，因为通知颜色很深，似乎通知面板中没有任何显示。我该怎么办？

   private void setupNotification(String s) {
 Intent notificationIntent_Restore = new Intent(this,Adult1Activity.class);
 notificationIntent_Restore.putExtra(EXTRA_NOTE,NOTE_RESTORE);
 PendingIntent restoreIntent = PendingIntent.getActivity(this,
 0, notificationIntent_Restore, PendingIntent.FLAG_UPDATE_CURRENT);

 final Intent notificationIntent_Close = new Intent(this, Adult1Activity.class);
 notificationIntent_Close.putExtra(EXTRA_NOTE, NOTE_CLOSE);
 PendingIntent closeIntent = PendingIntent.getActivity(this,
         1, notificationIntent_Close, PendingIntent.FLAG_UPDATE_CURRENT);


     if (Build.VERSION.SDK_INT < 16) {
         Notification n  = new Notification.Builder(this)
                 .setContentTitle("Stand Up!")
                 .setContentText(s)
                 .setSmallIcon(R.mipmap.ic_launcher)
                 .setContentIntent(restoreIntent)
                 .setAutoCancel(true)
                 .setColor(getResources().getColor(R.color.white_color))
                 .getNotification();
         NotificationManager notificationManager =
                 (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
         notificationManager.notify(0, n);
     } else {
         notification = new NotificationCompat.Builder(this)
                 .setSmallIcon(R.mipmap.ic_launcher)
                 .setContentTitle("Stand Up!")
                 .setContentText(s)
                 .setAutoCancel(true)
                 .setColor(getResources().getColor(R.color.black_color))
                 .addAction(new NotificationCompat.Action(R.drawable.ic_note_restore, "Restore", restoreIntent))
                 .addAction(new NotificationCompat.Action(R.drawable.ic_note_close, "Close", closeIntent))
                 .setContentIntent(restoreIntent)
                 .build();
         NotificationManager notificationManager =
                 (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        // notificationManager.notify();
     }

 startForeground(notification_id, notification);

 }

这是应用程序日志：

Answer 1

我认为最好遵循官方status bar icon guidelines并将图标颜色更改为白色。

Answer 2

我相信您的问题可以通过设置背景颜色来解决。所以这可以克服。

希望这个答案有效： Changing Notification RemoteViews Background Color

编辑：

为您提供工作代码，以便在任何版本的Android设备中显示通知文本。

背景背景特定于Kitkat和OS以下的操作系统。尝试使用它并提供反馈。

private void buildNotifications() {

    Intent notificationIntent_Restore = new Intent(this,Adult1Activity.class);
 notificationIntent_Restore.putExtra(EXTRA_NOTE,NOTE_RESTORE);
 PendingIntent restoreIntent = PendingIntent.getActivity(this,
 0, notificationIntent_Restore, PendingIntent.FLAG_UPDATE_CURRENT);

        android.support.v4.app.NotificationCompat.Builder builder = new NotificationCompat.Builder(this)
                .setSmallIcon(R.mipmap.ic_launcher)
                .setLargeIcon(R.mipmap.ic_launcher)
                .setContentIntent(clickIntent)
                .setContentTitle("Stand Up!")
                .setContentText(s)
                .setWhen(System.currentTimeMillis())
                .addAction(R.drawable.ic_skip_previous_white_36dp,
                        "",
                        retrievePlaybackAction(PREVIOUS_ACTION))
                .addAction(playButtonResId, "",
                        retrievePlaybackAction(TOGGLEPAUSE_ACTION))
                .addAction(R.drawable.ic_skip_next_white_36dp,
                        "",
                        retrievePlaybackAction(NEXT_ACTION));

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            builder.setShowWhen(false);
        }
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            builder.setVisibility(Notification.VISIBILITY_PUBLIC);
            NotificationCompat.MediaStyle style = new NotificationCompat.MediaStyle()
                    .setShowActionsInCompactView(0, 1, 2, 3);
            builder.setStyle(style);
        }
        builder.setColor(Color.parseColor("#403f4d"));
        Notification n = builder.build();

startForeground(notificationId, n);
}
