使用片段和圖像視圖的viewpager內存不足錯誤

我有這個內存不足的錯誤我有一個viewpager使用活動不片段和imageview然後當我得到這個錯誤我改變它爲碎片......但這個錯誤保持顯示我試過很多解決方案都沒有的它的工作...使用片段和圖像視圖的viewpager內存不足錯誤

我的代碼：

public class ScreenSlidePageFragment extends Fragment { 

    public static final String ARG_PAGE = "page"; 
    private int mPageNumber; 
    private int[] pics = {R.drawable.intro1, R.drawable.intro2,R.drawable.intro3,R.drawable.intro4,R.drawable.intro5,R.drawable.intro6,R.drawable.intro7,R.drawable.intro8, 
      R.drawable.intro9,R.drawable.intro10,R.drawable.intro11,R.drawable.intro12,R.drawable.intro13,R.drawable.intro14,R.drawable.intro15,R.drawable.intro16,R.drawable.intro17,R.drawable.intro18, 
      R.drawable.intro19,R.drawable.intro20,R.drawable.intro21,R.drawable.intro22,R.drawable.intro23,R.drawable.intro24,R.drawable.intro25,R.drawable.intro26,R.drawable.intro27,R.drawable.intro28,R.drawable.intro29,R.drawable.intro30, 
      R.drawable.intro31,R.drawable.intro32,R.drawable.intro33,R.drawable.intro34,R.drawable.intro35,R.drawable.intro36,R.drawable.intro37,R.drawable.intro38,R.drawable.intro39,R.drawable.intro40,R.drawable.intro41,R.drawable.intro42, 
      R.drawable.intro43,R.drawable.intro44,R.drawable.intro45,R.drawable.intro46,R.drawable.intro47,R.drawable.intro48,R.drawable.intro49,R.drawable.intro50,R.drawable.intro51,R.drawable.intro52,R.drawable.intro53,R.drawable.intro54, 
      R.drawable.intro55,R.drawable.intro56,R.drawable.intro57,R.drawable.intro58,R.drawable.intro59,R.drawable.intro60,R.drawable.intro61,R.drawable.intro62,R.drawable.intro63,R.drawable.intro64,R.drawable.intro65,R.drawable.intro66, 
      R.drawable.intro67,R.drawable.intro68,R.drawable.intro69,R.drawable.intro70,R.drawable.intro71,R.drawable.intro72,R.drawable.intro73}; 
    int count=72;//it's the number of the images-1; 



    public static ScreenSlidePageFragment create(int pageNumber) { 
     ScreenSlidePageFragment fragment = new ScreenSlidePageFragment(); 
     Bundle args = new Bundle(); 
     args.putInt(ARG_PAGE, pageNumber); 
     fragment.setArguments(args); 
     return fragment; 
    } 

    public ScreenSlidePageFragment() { 
    } 

    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     mPageNumber = getArguments().getInt(ARG_PAGE); 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) {  

     ViewGroup rootView = (ViewGroup) inflater 
       .inflate(R.layout.image_view_layout, container, false); 

     ImageView img=(ImageView) rootView.findViewById(R.id.img_pager); 
     img.setImageResource(pics[count-mPageNumber]); 

     return rootView; 
    } 


    public int getPageNumber() { 
     return mPageNumber; 
    } 


}

那麼活動是：

public class Introduction_Activity extends FragmentActivity { 
    private static final int NUM_PAGES = 73; 

    private ViewPager mPager; 


    private PagerAdapter mPagerAdapter; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_introduction); 


     // Instantiate a ViewPager and a PagerAdapter. 
     mPager = (ViewPager) findViewById(R.id.imgs_viewpager); 
     mPagerAdapter = new ScreenSlidePagerAdapter(getSupportFragmentManager()); 
     mPager.setAdapter(mPagerAdapter); 
     mPager.setCurrentItem(NUM_PAGES-1);  
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     // Inflate the menu; this adds items to the action bar if it is present. 
     getMenuInflater().inflate(R.menu.introduction_, menu); 
     return true; 
    } 


    static class ViewHolder { 
      ImageView img_view; 

     } 

    private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter { 
     public ScreenSlidePagerAdapter(FragmentManager fm) { 
      super(fm); 
     } 

     @Override 
     public Fragment getItem(int position) { 

      return ScreenSlidePageFragment.create(position); 

      } 

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




}

這是我的logcat：

我甚至說：

@Override 
    public void onDetach(){ 
     super.onDetach(); 
     //img.setImageResource(0); 

     FragmentManager fragmentManager = getFragmentManager(); 
     FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction(); 
     fragmentTransaction.remove(this).commit(); 
     Log.d("was detached","yes"); 
    }

我可以比以前多刷卡，但問題仍然存在... 是有沒有辦法查看我的應用程序的內存的可用空間？並請是否有人有一個解決方案...

suspicious：getItem（）返回一個ScreenSlidePageFragment.create（）...？在內存 – MiStr

634x700圖像給出1.69 MB不140KB ...嘗試使用mPager.setCurrentItem（X，FALSE）（不光滑）和後ScreenSlidePageFragment實例從活動 – Selvin

分離設置的ImageView爲null圖像@MiStr是那麼它會創建一個新的片段，並添加包含圖像的佈局.. – User

我不得不添加：

感謝buddy .....非常簡單的答案 –

，因爲你不浪費地顯示位圖（順便說一句，請記住，logcat的是不可選的，你必須總是將它張貼）你得到這個錯誤。

我建議你自己閱讀並實施this official guide。

如果你想在你的APL使用唯一的形象，嘗試這項活動
