Configuration de la visibilité d'une vue d'image en fonction des préférences partagées

Question

I Programm a Quiz App. J'ai déjà mis en place que si le highscore est supérieur à 10, un ImageView sera affiché en permanence. Cela fonctionne très bien aussi au redémarrage de l'application, le seul problème est que si l'utilisateur atteint un highscore de par exemple 11 et directement plus tard au début du quiz répond correctement, puis faux, le ImageView disparaît. La préférence partagée est dans l'activité principale (activité Quiz) et sera appelée dans Menu2 (deuxième activité).

Quiz Activité 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();

Answer 1

dans votre updateScore vous enregistrez les données, peu importe ce que le score est, de sorte que vous supprimez la valeur ancienne et changez-le avec le nouveau, donc vous devez lire le vieux score et le comparer avec le mScore comme ceci:

SharedPreferences mypref =getPreferences(MODE_PRIVATE); 
int highScore = mypref.getInt("highScore", 0); 
if(mScore> highScore){ 
    SharedPreferences.Editor editor = mypref.edit(); 
    editor.putInt("currentscore", mScore); 
    editor.apply(); 
} 

Answer 2

Cela se produit parce que vous avez le code suivant

if (applyView >=10) { 
    imgTrophyView1.setVisibility(View.VISIBLE); 
    bttPOPUP.setVisibility(View.VISIBLE); 
} 
    if (applyView >= 20){ 
     imgTrophyView2.setVisibility(View.VISIBLE); 

} 

qui vérifie la « currentScore » si l'utilisateur trouve seulement 1 réponse la deuxième fois qu'il joue, il va être 1 si l'image a gagné » t montrer. Je remarque que vous avez un sharedPref pour le score actuel et que vous le transmettez également avec intention. Vous avez également un autre sharedPref? Ma suggestion est de le passer seulement avec l'intention et ensuite vérifier si c'est un highscore, alors enregistrez-le dans sharedPref. Et seulement un sharedPref.

EDIT

Supprimer le code ci-dessous de updateScore

SharedPreferences sharedpreferences = getSharedPreferences("mypref", Context.MODE_PRIVATE); 
SharedPreferences.Editor editor = sharedpreferences.edit(); 
editor.putInt("currentscore", mScore); 
editor.apply(); 

Retirez ensuite/modifier tout le code pref partagé que vous avez dans le menu 2 avec quelque chose comme ça

SharedPreferences sharedpreferences = getSharedPreferences("mypref", Context.MODE_PRIVATE); 

//first time high score 
if (sharedPreferences.getInt("highScore", 0) == 0) 
{ 
    SharedPreferences.Editor editor = sharedPreferences.edit(); 
    editor.putInt("highScore", mScore); 
    editor.apply(); 
} 
else 
{ 
    int oldScore = sharedPreferences.getInt("highScore", 0); 

    //new high score 
    if (mScore > oldScore) 
    { 
     SharedPreferences.Editor editor = sharedPreferences.edit(); 
     editor.putInt("highScore", mScore); 
     editor.apply(); 
    } 
}
