Android在自定義列表視圖內存不足

你好，我面臨的問題是，我有一個自定義列表視圖，其中包含7個位圖圖像，但當我試圖滾動我收到內存不足的錯誤，我有改變了所有的圖像大小，我的圖像都沒有超過50kb。我試圖改變清單內的堆，但我想知道是否有任何建議。我已經包含了提交給我的錯誤。Android在自定義列表視圖內存不足

，我用它來填充我的ListView當前適配器

public class myAdapter extends ListFragment { 


String[] liqueurs= {"Almond", "Cherry", "Chocolate Orange", "Lemon", "Orange", "Chocolate"}; 
String[] description = { 
     "test", 
     "With a delicious bite of fresh cherry, this can be drunk alone, or mixed with the Almond to make a Cherry Bakewell.", 
     "Sweet, rich and smooth. Try it over ice-cream, cooked in a cake, or just sipped from a glass.", 
     "Your classic Italian drink without the sharp finish. Absolutely delicious after dinner.", 
     "Clean, fresh and with a sweet tang. Our orange liqueur is just the thing to wake your taste buds up.", 
     "Made from real ground coco beans, surely this counts as 1 of your 5 a day"}; 
String[] prices = {"£7.99", "£7.99", "£7.99", "£7.99", "£7.99", "£7.99"}; 
int[] images ={R.drawable.almond, R.drawable.cherry, R.drawable.chocolateorange, R.drawable.lemon, R.drawable.orange, R.drawable.chocolate}; 


ArrayList<HashMap<String, String>> data = new ArrayList<HashMap<String, String>>(); 
SimpleAdapter adapter; 

public LiqueuresAdapter() { 
    // Required empty public constructor 
} 


@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    // Inflate the layout for this fragment 




    HashMap<String, String> map = new HashMap <String, String>(); 





    for(int i=0;i<liqueurs.length;i++){ 

     map = new HashMap<String, String>(); 
     map.put("liqueurs",liqueurs[i]); 
     map.put("description", description[i]); 
     map.put("prices", prices[i]); 
     map.put("Image", Integer.toString(images[i])); 

     data.add(map); 


    } 

    String[] from = {"liqueurs", "Image", "description", "prices"}; 



    int[] to={R.id.wineName, R.id.wineImage, R.id.wineDes, R.id.winePrice}; 

    adapter = new SimpleAdapter(getActivity(), data, R.layout.custom_winelist, from, to); 
    setListAdapter(adapter); 



    // return inflater.inflate(R.layout.fragment_contact_us, container, false); 

    return super.onCreateView(inflater, container, savedInstanceState); 



} 


@Override 
public void onStart() { 
    super.onStart(); 
} 


// Removes duplicate id error by destroying the container and rebuilding it when next selected 
@Override 
public void onDestroyView() { 
    FragmentManager fm = getFragmentManager(); 

    Fragment xmlFragment = fm.findFragmentById(R.id.fragment_container); 
    if (xmlFragment != null) { 
     fm.beginTransaction().remove(xmlFragment).commit(); 
    } 

    super.onDestroyView(); 
} 
}

我建議你使用滑翔或畢加索加載，緩存和管理圖像，也可以使用ViewHolder設計模式優化您的ListView性能並減少內存中的負載。基本上，ViewHolder所做的就是重複使用視圖而不增加新視圖（這增加了內存）。這可能會降低你的記憶力。 Here是我的GitHub帳戶中有關如何自定義ListView中的ArrayAdapter以合併ViewHolder的示例。我希望它有幫助！

嗨艾薩克我已經下載了你的項目，這是非常有用的，它很有趣，看你如何得到它與JSON的工作。查看數組適配器類後，是否可以更改您的代碼，以便查看我上面列出的數組？ – james

是的，這是可能的，我會在週末看看 –

那好吧，我一直在查看持有人，因爲你的消息，我想我已經排序的問題：D – james
