確定哪個公式運行的複選框

我試圖讓某些複選框的檢查決定運行哪個公式。該課程的代碼如下。問題中的代碼是註釋掉的代碼。確定哪個公式運行的複選框

    charisma.addTextChangedListener(watcher); 
    persuasion.addTextChangedListener(watcher);

} 

@Override 
public void onBackPressed() 
{ 
    Intent intent = new Intent (this, NewSkillsAndAttributes.class); 
     startActivity(intent); 
}

}

的問題是這會導致應用程序崩潰一旦開始了活動。我哪裏錯了？

這裏的logcat的：

你確定他們已被正常初始化的意見（膽小和charismafpvalue）嗎？ – Slampy 2014-09-23 14:47:10

我很確定他們是，但以防萬一我已將整個'SaACharisma.class'添加到OP – Mikitz06 2014-09-23 14:51:30

您的意思是「OP」？（英語不是我的母語）你可以發表你的OnCreate方法 – Slampy 2014-09-23 14:54:57

對於SharedPrefs我使用片斷。

public class SharedPrefsHelper

    private static Map<String, Boolean> prefsBool = new ConcurrentHashMap<String, Boolean>();

    public static SharedPreferences.Editor getEditor(Context ctx) 
    { 
     SharedPreferences sharedPreferences = ctx.getSharedPreferences(Constants.Prefs.PREFS_NAME, Context.MODE_PRIVATE); 
     return sharedPreferences.edit(); 
    } 

    public static SharedPreferences getPrefs(Context ctx) 
    { 
     return ctx.getSharedPreferences(Constants.Prefs.PREFS_NAME, Context.MODE_PRIVATE); 
    } 

    public static boolean getBoolean(Context context, String key, boolean defaultVal) 
    { 
     if (prefsBool.containsKey(key)) 
     { 
      return prefsBool.get(key); 
     } else 
     { 
      boolean val = getPrefs(context).getBoolean(key, defaultVal); 
      prefsBool.put(key, val); 
      return val; 
     } 
    } 

    public static String getString(Context context, String key, String defValue) 
    { 
     if (prefsString.containsKey(key)) 
     { 
      return prefsString.get(key); 
     } else 
     { 
      String val = getPrefs(context).getString(key, defValue); 
      prefsString.put(key, val); 
      return val; 
     } 
    } 
    public static long getLong(Context context, String key, long defValue) 
    { 
     if (prefsLong.containsKey(key)) 
     { 
      return prefsLong.get(key); 
     } else 
     { 
      long val = getPrefs(context).getLong(key, defValue); 
      prefsLong.put(key, val); 
      return val; 
     } 
    } 

    public static void putString(Context context, String key, String val) 
    { 
     prefsString.put(key, val); 
     SharedPreferences.Editor editor = getEditor(context); 
     editor.putString(key, val); 
     editor.commit(); 
    } 

    public static void putBoolean(Context context, String key, boolean val) 
    { 
     prefsBool.put(key, val); 
     SharedPreferences.Editor editor = getEditor(context); 
     editor.putBoolean(key, val); 
     editor.commit(); 
    } 
    public static void putLong(Context context, String key, long val) 
    { 
     prefsLong.put(key, val); 
     getEditor(context).putLong(key, val).commit(); 

    } 

}

我該如何去檢查'膽小' 'sanguine'在我的活動中有鑰匙？ – Mikitz06 2014-09-23 15:46:43

將類保存在Constans類中（使它們成爲靜態）...並使用任何你想要的 – Slampy 2014-09-24 08:09:15
