android - 语言不变

Question

After I exit my App and open it again, then language is changed, how can I do it without restarting the App

I am using RecyclerView to load the data from change_language function

Here is my change_language function :

public void change_language() {
        if (EasyPreference.with(getApplicationContext(), PRE_KEY)
                .getString(PRE_USER_LANGUAGE, PRE_LANGUAGE_ENGLISH).equalsIgnoreCase(PRE_LANGUAGE_ASSEMESS)) {

            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_google_classroom, Constant.classroom[2]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_news_alerts, Constant.news[2]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_school_rank, Constant.announcement[2]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.school_diary, Constant.school_diary[2]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_absent_report, Constant.absent_report[2]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.examination, Constant.examination[2]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_events, Constant.events[2]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_resources, edu_forum[2]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.edu_forum_finals, Constant.edu_forum[2]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.sets, Constant.settings[2]));


        } else if (EasyPreference.with(getApplicationContext(), PRE_KEY)
                .getString(PRE_USER_LANGUAGE, PRE_LANGUAGE_ENGLISH).equalsIgnoreCase(PRE_LANGUAGE_THI)) {

            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_google_classroom, Constant.classroom[1]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_news_alerts, Constant.news[1]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_school_rank, Constant.announcement[1]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.school_diary, Constant.school_diary[1]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_absent_report, Constant.absent_report[1]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.examination, Constant.examination[1]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_events, Constant.events[1]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_resources, edu_forum[1]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.edu_forum_finals, Constant.edu_forum[1]));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.sets, Constant.settings[1]));


        } else {

            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_google_classroom, "Classroom"));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_news_alerts, "Notice"));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_school_rank, "Announcement"));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.school_diary, "School Diary"));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_absent_report, "Absent report"));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.examination, "Examination"));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_events, "Events"));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_resources, "Edu Forum"));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.edu_forum_finals, "Edu Bank"));
            myTeacherModelLists.add(new MyTeacherModel(R.drawable.sets, "Settings"));

        }

Here are the Arrays from where the language is fetched (Inside Constant.java file ):

  public static String[] edu_forum = {"Edu Forum", "ฟอรั่มการศึกษา", "শিক্ষা আলোচনা"};
public static String[] news = {"Notice", "ข่าว", "জাননী"};

添加列表后，只需notifyDataSetChanged如下

 public void change_language() {
            if (EasyPreference.with(getApplicationContext(), PRE_KEY)
                    .getString(PRE_USER_LANGUAGE, PRE_LANGUAGE_ENGLISH).equalsIgnoreCase(PRE_LANGUAGE_ASSEMESS)) {

                myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_google_classroom, Constant.classroom[2]));
                myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_news_alerts, Constant.news[2]));
                myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_school_rank, Constant.announcement[2]));
                myTeacherModelLists.add(new MyTeacherModel(R.drawable.school_diary, Constant.school_diary[2]));
                myTeacherModelLists.add(new MyTeacherModel(R.drawable.home_absent_report, Constant.absent_report[2]));
                myTeacherModelLists.add(new MyTeacherModel(R.drawable.examination, Constant.examination[2]));

                myTeacherModelLists.add(new MyTeacherModel(R.drawable.sets, Constant.settings[2]));

     adapter.notifyDataSetChanged();
            } else if (EasyPreference.with(getApplicationContext(), PRE_KEY)
                    .getString(PRE_USER_LANGUAGE, PRE_LANGUAGE_ENGLISH).equalsIgnoreCase(PRE_LANGUAGE_THI)) {
