     SharedPreferences settings =getSharedPreferences(GAME_PREFERENCES,MODE_PRIVATE); 

     SharedPreferences.Editor prefEditor = settings.edit(); 
     prefEditor.putString("Gama x","Blue Spec");

Answer 1

之前開始隨機編碼，在我看來看看例如this is the best一些Android的教程。

你可以從編碼開始。

順便說一句溶液移動它 「的onCreate」 方法內：

public class Alpha extends Activity { 
    public static final String GAME_PREFERENCES = "GamePrefs"; 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     SharedPreferences settings =getSharedPreferences(GAME_PREFERENCES,MODE_PRIVATE); 

     SharedPreferences.Editor prefEditor = settings.edit(); 
     prefEditor.putString("Gama x","Blue Spec"); 
     prefEditor.putInt("Wave",292); 
     prefEditor.commit(); 
    } 
}
