Lors de la saisie d'un nom par l'utilisateur, comment l'obtenir pour rester sur l'activité lors du redémarrage?

Question

Dans mon application de devinette Android, j'ai réussi à l'obtenir où lorsqu'un utilisateur saisit son nom sur une activité, il s'affiche sur le jeu lui-même. Mon problème, cependant, se produit lorsque l'utilisateur clique sur «oui» pour avoir un autre coup. Le jeu fonctionne bien mais leur nom disparaît. Je sais que c'est parce que l'activité recommence mais qu'on ne lui dit pas de porter le nom entré car cela a été fait via la méthode onOptionsItemsSelected et cliquer sur yes via la méthode OnClickListener mais je ne comprends pas comment je devrais "fusionner" les deux , si c'est un tour de phrase approprié.

Mes cours sont ci-dessous:

public class GameCentral extends AppCompatActivity { 

int backButtonCount = 0; 


public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.game_central_layout); 
} 

@Override 
public boolean onCreateOptionsMenu(Menu menu) { 

    getMenuInflater().inflate(R.menu.commonmenus, menu); 
    return super.onCreateOptionsMenu(menu); 
} 

@Override 
**public boolean onOptionsItemSelected(MenuItem item) { 
    int id = item.getItemId(); 
    if (id == R.id.guessingGame) { 
     // displays name entered on the game itself 
     startActivity(new Intent(this, Task3Activity.class)); 
     switch (item.getItemId()) { 
      case R.id.guessingGame: 
       Intent intent = new Intent(GameCentral.this, Task3Activity.class); 
       EditText playerName = (EditText) findViewById(R.id.playerNameInput); 
       intent.putExtra("PlayerName", playerName.getText().toString()); 
       startActivity(intent); 
       return true; 
      default: 
       return super.onOptionsItemSelected(item); 
     }** 
    } else if (id == R.id.placeOne) { 

     Toast.makeText(this, "Game Placeholder One option is Clicked", Toast.LENGTH_SHORT).show(); 
    } else if (id == R.id.placeTwo) { 

     Toast.makeText(this, "Game Placeholder Two option is Clicked", Toast.LENGTH_SHORT).show(); 
    } else if (id == R.id.placeThree) { 

     Toast.makeText(this, "Game Placeholder Three option is Clicked", Toast.LENGTH_SHORT).show(); 
    } 

    return super.onOptionsItemSelected(item); 
} 

public void onBackPressed() { 
    // when the back button is pressed on the mobile, two presses takes you back out of the app completely 
    if (backButtonCount >= 1) { 
     Intent backIntent = new Intent(Intent.ACTION_MAIN); 
     backIntent.addCategory(Intent.CATEGORY_HOME); 
     backIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
     startActivity(backIntent); 
    } else { 
     Toast.makeText(this, "Press the back button again to close the application", Toast.LENGTH_SHORT).show();

}

Pouvez-vous essayer d'utiliser un SharedPreferences peut-être?

SharedPreferences sharedPreferences = getSharedPreferences("NameList", MODE_PRIVATE); 
SharedPreferences.Editor editor = sharedPreferences.edit(); 

editor.putString("Name1", playerName); 

editor.apply(); 

Puis vient le chercher le faire:

SharedPreferences sharedPreferences = getSharedPreferences("NameList", MODE_PRIVATE); 
String playerName = sharedPreferences.getString("Name1", "Default name");
