Android 通知按钮未显示 [英] Android Notification buttons not showing up

问题描述

这是我用按钮设置通知的代码.

This is my code to set up a notification with buttons.

Intent receiverIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        PendingIntent pReceiverIntent = PendingIntent.getActivity(ctx, 1, receiverIntent, 0);
        Intent clearIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        clearIntent.setAction("clear");
        PendingIntent pClearIntent = PendingIntent.getActivity(ctx, 1, clearIntent, 0);

        Intent colorsIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        colorsIntent.setAction("colors");
        PendingIntent pColorsIntent = PendingIntent.getActivity(ctx, 1, colorsIntent, 0);

        Intent animationIntent = new Intent(ctx, ResponsivePrefsActivity.class);
        animationIntent.setAction("animation");
        PendingIntent pAnimation = PendingIntent.getActivity(ctx, 1, animationIntent, 0);

        Notification.Builder builder;
        builder = new Notification.Builder(ctx).setSmallIcon(R.drawable.ic_launcher).setAutoCancel(false)
                .setContentTitle("Draw Me: A Live Wallpaper").setContentText("Never get bored again!")
                .setContentIntent(pReceiverIntent).addAction(R.raw.ic_menu_close_clear_cancel, "Clear", pClearIntent)
                .addAction(R.raw.ic_menu_edit, "Colors", pColorsIntent).addAction(R.raw.ic_menu_play_clip, "Animation", pAnimation);
        Notification notification = builder.build();

        NotificationManager notificationManager = (NotificationManager) ctx.getSystemService(Context.NOTIFICATION_SERVICE);

        notificationManager.notify(0, notification);

通知显示但按钮不显示.我的设备有 Android 4.1.1我在 Fragment 中设置了此通知.我究竟做错了什么?谢谢！

推荐答案

让我告诉你一些非常尴尬的事情.如果您的持续通知中有任何内容，您将看不到按钮.通常，当您通过 USB 将手机连接到 PC 时会发生这种情况.希望这能解决您的问题

Let me tell you something which is really awkward. If you have anything in your Ongoing Notification, You wont see the buttons. Typically it happens when you have phone connected to PC via USB. Hope this solves your problem
