我正在notification我的应用程序中显示OS versions除了Android 7.0(Nougat)以外的所有工作正常.这是代码

  Intent notificationIntent = new Intent(context, HomeScreenActivity.class);

        // set intent so it does not start a new activity
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);

        PendingIntent intent = PendingIntent.getActivity(context, 0, new Intent(), PendingIntent.FLAG_UPDATE_CURRENT | Notification.FLAG_AUTO_CANCEL | Notification.FLAG_SHOW_LIGHTS);

        Notification.Builder builder = new Notification.Builder(context);
        builder.setContentIntent(intent)
                .setAutoCancel(true)
                .setPriority(Notification.PRIORITY_MAX)
                .setContentTitle(title)
                .setStyle(new Notification.BigTextStyle().bigText(message))
                .setContentText(message);
        if (Build.VERSION.SDK_INT >= 21)
            builder.setVibrate(new long[0]);

        notification.flags = Notification.DEFAULT_LIGHTS | Notification.FLAG_AUTO_CANCEL;
        if (android.os.Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP){
            builder.setColor(context.getResources().getColor(R.color.colorPrimary));
            builder.setSmallIcon(R.drawable.ic_nav_reward_point);
        }else{
            builder.setSmallIcon(R.drawable.launcher_icon);
        }
        builder.setAutoCancel(true);
        builder.setContentIntent(intent);
        notification.flags |= Notification.FLAG_AUTO_CANCEL; …

我有一个类型的哈希图String,ArrayList<String>.两个不同keys的存储在哈希映射中,其中包含值列表.

现在我必须比较不同键的值并提取公共值.怎么能实现这个功能？

以下是Hashmap我使用的类型:

示例列表:

{Size=[43, 53, 63, 48, 58], Color=[66, 62, 65, 64, 63]}

这是代码......

    private HashMap<String, ArrayList<String>> mapMatchvalues = new HashMap<>();

     for (Map.Entry<String, ArrayList<String>> map3 : mapMatchvalues.entrySet()) {
     List<String> getList1 = new ArrayList<>();
     getList1 = map3.getValue();

           for (int i = 0; i < getList1.size(); i++) {
                   if (getList.contains(getList1.get(i))) {
                    //Print values
                    } else {
                   // Print if not matched....
             }
      }
}

我正在为phone和实现一个应用程序tablet.我不确定哪个layout folder和value folder将被包含在项目中.任何人都可以给我一些关于layout folders要包含在res应用程序文件夹中的想法.
