您好我試圖從列表視圖中保存用戶首選項我想要它存儲選定的內容,然後當應用程序再次加載檢查偏好選擇的方法if it = team then做一些事情,但目前它沒有加載任何關於我做錯的想法。當我退出選擇的方法,它說空android共享首選項檢索

繼承人我的代碼

preferences.edit().putString("ChosenMethod", "Team").commit(); 
    preferences.edit().putString("ChosenTeam", ChosenTeam).commit(); 
    preferences.edit().putString("ChosenTeamId", ChosenTeam).commit(); 
    preferences.edit().putString("ChosenLeagueId", ChosenTeam).commit(); 
    preferences.edit().putString("ChosenDivisionID", ChosenTeam).commit(); 

然後在introActivity我已經把這個這個

protected void checkPreferences(){ 


    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(this); 
    Log.v("myapp", "prefs = " + preferences); 
    String ChosenMethod = preferences.getString("ChosenTeam", chosenMethod); 
    Log.v("myapp", "ChosenMethod = " + ChosenMethod); 

    if (ChosenMethod != null){ 

     Intent intent = new Intent(TheEvoStikLeagueActivity.this,Activity.class); 

    } 




} 


      @Override 

      public void onCreate(Bundle icicle) { 

        super.onCreate(icicle); 

        setContentView(R.layout.main); 
        checkPreferences();

//Retrive value from SharedPreference 
public static String getStringFromSP(String key) { 
// TODO Auto-generated method stub 
    SharedPreferences preferences = getApplicationContext().getSharedPreferences(" SHARED_PREFERENCES_NAME ", android.content.Context.MODE_PRIVATE); 
    return preferences.getString(key, null); 
}//getPWDFromSP() 

你可以使用上面的代碼獲得來自SharedPreference的值。 請參閱此LINK

SharedPreferences preferences = _activity.getSharedPreferences(「SHARED_PREFERENCES_NAME」,android.content.Context.MODE_PRIVATE); String ChosenMethod = preferences.getString(「ChosenMethod」,ChosenMethod);繼承人我放了n它不喜歡括號中的選擇方法 – iamlukeyb
