如何向Viewpager添加首選項屏幕？

Question

我是Android開發的小菜鳥，我在viewpager中看到了一個顯示偏好屏幕的問題。目前，我的應用程序正在將viewpager的所有頁面混亂顯示爲一個以首選項屏幕作爲背景的頁面。然後，當我舉手時，應用程序因InflateException而崩潰。我已經研究了SO問題here和here的潛在原因，但都沒有提供解決方案來糾正我的問題。我只是使用偏好片段，但我正在開發最小8 API。任何幫助是極大的讚賞。

我的代碼

public class Options extends PreferenceActivity implements OnClickListener ,SharedPreferences.OnSharedPreferenceChangeListener{ 

ActionBarSherlock mSherlock = ActionBarSherlock.wrap(this); 
View view; 

@Override 
public void onCreate(Bundle savedInstanceState) { 
    setTheme(R.style.Theme_Sherlock); 
    super.onCreate(savedInstanceState); 

    addPreferencesFromResource(R.xml.prefs); 
    PreferenceManager.getDefaultSharedPreferences(this).registerOnSharedPreferenceChangeListener(this); 

    mSherlock.setContentView(R.layout.options); 

MyPagerAdapter adapter = new MyPagerAdapter(this); 
ViewPager myPager = (ViewPager) findViewById(R.id.viewpager); 
myPager.setAdapter(adapter); 
myPager.setCurrentItem(2); 
TitlePageIndicator indicator = (TitlePageIndicator)findViewById(R.id.indicator); 
indicator.setViewPager(myPager); 
indicator.setOnPageChangeListener(new ViewPager.OnPageChangeListener() { 
    @Override 
    public void onPageSelected(int position) { 

      if(position == 0 ||position == 1||position == 2||position == 4){ 

      } 
    } 

    @Override 
    public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { 
    } 

    @Override 
    public void onPageScrollStateChanged(int state) { 
    } 
}); 
} 

private class MyPagerAdapter extends PagerAdapter { 

    private String[] titles = new String[] {"HELP", "PREFERENCES", "ABOUT" }; 
private final Context context; 
private int[] scrollPosition = new int[titles.length]; 

public MyPagerAdapter(Context context) 
{ 
    this.context = context; 
    for (int i = 0; i < titles.length; i++) 
    { 
     scrollPosition[i] = 0; 
    } 
} 

@Override 
public String getPageTitle(int position) 
{ 
    return titles[position]; 
} 

@Override 
public int getCount() 
{ 
    return titles.length; 
} 



    public Object instantiateItem(View collection, int position) { 

     LayoutInflater inflater = (LayoutInflater) collection.getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 


     int resId = 0; 
     switch (position) { 
     case 2: 
      resId = R.layout.help;    
      view = inflater.inflate(resId, null); 
      LinearLayout layout0=(LinearLayout)view.findViewById(R.id.helplayout); 
      ((ViewPager) collection).addView(view, 0); 
      return view; 

     case 0: 
      resId = R.xml.prefs; 
      view = inflater.inflate(resId, null); 
      LinearLayout layout1=(LinearLayout)view.findViewById(R.id.RLcoins); 


      ((ViewPager) collection).addView(view, 0); 
      return view; 

     case 1: 
      resId = R.layout.about; 
      view = inflater.inflate(resId, null); 
      LinearLayout layout2=(LinearLayout)view.findViewById(R.id.LLtwitter); 


      ((ViewPager) collection).addView(view, 0); 
      return view; 



     } 
     return resId; 

    }

你應該/關於使用片段的幫助，爲喜好PreferenceFragment。

下面是PreferenceFragment http://android-er.blogspot.com.ar/2012/07/example-of-using-preferencefragment.html
