这是我用按钮设置通知的代码.

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);
