添加sharedPreferences到listpreference值

Question

我的應用程序與閃屏開始然後去MainActivity取決於其選擇在listpreference任何選項來確定用戶的偏好：

1-開始應用，但不飛濺和音樂。

2-啓動應用程序只有飛濺。

3-啓動應用程序與飛濺和音樂。

我實現listpreference，但我不能添加sharedPreferences每個值，以便檢查後其中的任何它存儲在sharedPreferences和啓動應用程序依賴於用戶的喜好，

，因爲這是第一次使用listpreference和IM新Android我不知道該怎麼做，

任何幫助，將不勝感激。

Splash.java

public class Splash extends Activity{ 
MediaPlayer ourSong; 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
     setContentView(R.layout.splash); 

    ourSong = MediaPlayer.create(Splash.this, R.raw.splashsound);  
    ourSong.start(); 

    Thread timer = new Thread(){ 
     public void run(){ 
      try{ 
       sleep(2000); 
       } 
       catch (InterruptedException e){ 
       e.printStackTrace(); 
       } 
       finally{ 
        Intent intent = new Intent(Splash.this, MainActivity.class);          
        startActivity(intent); 
        } 
      }         
     }; 
     timer.start(); 
     } 
@Override 
protected void onPause() { 
      // TODO Auto-generated method stub 
    super.onPause(); 
    ourSong.release(); 
    finish(); 
      } 
     } 

Prefs.java

public class Prefs extends PreferenceActivity{ 

@SuppressWarnings("deprecation") 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 

    addPreferencesFromResource(R.xml.prefs); 
    } 
} 

的prefs.xml

<?xml version="1.0" encoding="utf-8"?> 
<PreferenceScreen 
    xmlns:android="http://schemas.android.com/apk/res/android"> 

    <ListPreference 
     android:title="Application Start Preference" 
     android:summary="This preference allows to select how the app will start" 
     android:key="listPref" 
     android:entries="@array/splash" 
     android:entryValues="@array/splash_values" />   
</PreferenceScreen> 

arrays.xml

<?xml version="1.0" encoding="utf-8"?> 
<resources> 
    <string-array name="splash"> 
     <item>start app without splash screen </item> 
     <item>start app with splash scrren only</item> 
     <item>start app with splash screen and music</item> 
    </string-array> 

    <string-array name="splash_values"> 
     <item>1</item> 
     <item>2</item> 
     <item>3</item> 

    </string-array>  
</resources> 

UPDATE： 我想下面的代碼，但最新發生的是應用程序的正常運行飛濺開始，然後去mainactivity然後我按偏好選項菜單中的OK它打開首選項頁面，然後按listpreference它上升3個單選按鈕的對話框，如果我按任何一個單選按鈕它的確定，然後我退後，直到退出的應用程序，然後再次打開它直接打開顯示主要活動沒有飛濺，然後立即崩潰。

在logcat的還行23：

int splashType = getPrefs.getInt("listPref", 0); 

Splash.java

public class Splash extends Activity{ 
MediaPlayer ourSong; 
@Override 
    protected void onCreate(Bundle savedInstanceState) { 
    this.requestWindowFeature(Window.FEATURE_NO_TITLE); 
    // TODO Auto-generated method stub 
    super.onCreate(savedInstanceState); 
     setContentView(R.layout.splash); 

    SharedPreferences getPrefs = PreferenceManager.getDefaultSharedPreferences 
      (getBaseContext()); 

int splashType = getPrefs.getInt("listPref", 0); 
    switch (splashType) { 
    case 2: 
Intent intent = new Intent(Splash.this, MainActivity.class);          
     startActivity(intent); 
    break; 

    case 1: 
    setContentView(R.layout.splash); 
    Thread timer = new Thread() 
    { 
    public void run() 
    { 
     try 
     { 
      sleep(2000); 
     } 
     catch (InterruptedException e) 
     { 
      e.printStackTrace(); 
     } 
     finally 
     { 
      Intent intent = new Intent(Splash.this, MainActivity.class);          
      startActivity(intent); 
     } 
     }       
    }; 
    timer.start();  
break; 

case 0: 
    ourSong = MediaPlayer.create(Splash.this, R.raw.splashsound); 
    ourSong.start(); 

Thread timer1 = new Thread(){ 
    public void run(){ 
     try{ 
      sleep(2000); } 
      catch (InterruptedException e){ 
      e.printStackTrace(); } 
      finally{ 
      Intent intent = new Intent(Splash.this, MainActivity.class);          
       startActivity(intent); 
        } 
        }          
       }; 
      timer1.start(); 
    break; 
    } 
    } 
@Override 
protected void onPause() { 
    // TODO Auto-generated method stub 
    super.onPause(); 
    ourSong.release(); 
    finish(); 
     } 
    }

您可以嘗試類似的東西來獲得存儲的用戶偏好和然後採取相關措施：

SharedPreferences sharedPrefs; 
sharedPrefs = PreferenceManager.getDefaultSharedPreferences(this); 
String userSplashValue = sharedPrefs.getString("listPref", "1"); 

if (userSplashValue.equals ("1")) { 
// choice 1 
} 
else if (userSplashValue.equals("2")) { 
// choice 2  
} 
else if (userSplashValue.equals ("3")){ 
// choice 3  
}
