I Programm a Quiz App. I already set up that if the highscore is over 10, an ImageView will be shown permanently. That works very fine also on restart of the app, the only problem is that if the user reachs a highscore of for example 11 and directly later on the beginning of the quiz answers correctly and then false, the ImageView disappears. The shared preference is in the Main Activity (Quiz activity) and will be calles in Menu2 (second Activity).
Quiz Activity java:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_quiz);
//Randromizes the row of the questions
QuestionLibrary q = new QuestionLibrary();
System.out.printf("Question:0 Choice:(%s, %s, %s) Answer:%s%n",
q.getChoice1(0), q.getChoice2(0), q.getChoice3(0), q.getCorrectAnswer(0));
q.shuffle();
System.out.printf("Question:0 Choice:(%s, %s, %s) Answer:%s%n",
q.getChoice1(0), q.getChoice2(0), q.getChoice3(0), q.getCorrectAnswer(0));
mQuestionLibrary.shuffle();
//End randomizer
//We need this for the NAVIGATION DRAWER
mToolbar = (Toolbar) findViewById(R.id.nav_action);
setSupportActionBar(mToolbar);
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
mToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.open, R.string.close);
mDrawerLayout.addDrawerListener(mToggle);
mToggle.syncState();
getSupportActionBar().setDisplayHomeAsUpEnabled(true); //Able to see the Navigation Burger "Button"
