Android ViewPager FragmentManager無法應用錯誤

Question

我以常規方式使用傳呼機視圖。在下面的代碼中，我得到錯誤：android.support.v4.app.FragmentManager cannot be applied to android.app.FragmentManager。我檢查了這一切的解決方案，並實現它們，因爲它們可以看出（進口的似乎OK），仍然我有這樣的錯誤...

import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentActivity; 
import android.support.v4.app.FragmentManager; 
import android.support.v4.app.FragmentStatePagerAdapter; 
import android.support.v4.view.PagerAdapter; 
import android.support.v4.view.ViewPager; 

public class MyActivity extends FragmentActivity { 

    private static int NUM_PAGES = 0; //The number of pages to show. 
    private static ViewPager mPager; //The pager widget 
    private static PagerAdapter mPagerAdapter; //The pager adapter 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_my); 
     mPager = (ViewPager) findViewById(R.id.pager); 
     //Next line is error 
     mPagerAdapter = new ScreenSlidePagerAdapter(getFragmentManager()); 
     mPager.setAdapter(mPagerAdapter); 
    } 

    /** 
    * A simple pager adapter 
    */ 
    private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter { 
     public ScreenSlidePagerAdapter(FragmentManager fm) { 
      super(fm); 
     } 

     @Override 
     public Fragment getItem(int position) { 
      return MyFragment.create(position); 
     } 

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

使用getSupportFragmentManager()，而不是getFragmentManager()。根據您班級的進口情況，您正在使用支持部門的Fragment
