单击ListView项目时出现内存异常

我正在尝试创建一个列表视图，该列表视图具有每个元素的背景图像以及显示在顶部的文本视图。列表视图填充正确，但直接单击该项目会引发错误。单击ListView项目时出现内存异常

这里是我的列表视图元素的XML（menu_section.xml）

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="75dp"> 

    <ImageView 
     android:id="@+id/section_bg_image" 
     android:layout_width="match_parent" 
     android:layout_height="75dp" 
     android:adjustViewBounds="true" 
     android:scaleType="centerCrop"/> 


     <TextView 
      android:id="@+id/section_title" 
      android:layout_width="match_parent" 
      android:layout_height="75dp" 
      android:layout_gravity="end" 
      android:background="@color/colorBlackTranslucent" 
      android:gravity="right|center_vertical" 
      android:paddingLeft="20dp" 
      android:paddingRight="20dp" 
      android:text="Hello World" 
      android:textColor="@color/colorWhite" 
      android:textSize="24sp" /> 

</RelativeLayout>

这是我的适配器MenuAdapter.java。我正从资产文件夹加载背景图片。每个图像是〜并且是50 Kb现在有一个总的图像〜400KB的（与列表中的8个项目）

import android.app.Activity; 
import android.content.Context; 
import android.content.res.AssetManager; 
import android.net.Uri; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.ArrayAdapter; 
import android.widget.ImageView; 
import android.widget.TextView; 

import com.squareup.picasso.Picasso; 

import java.util.List; 

import com.myapp.hotel.MyUtility; 
import com.myapp.hotel.R; 

public class MenuAdapter extends ArrayAdapter<MenuSection> { 

    Context context; 
    List<MenuSection> menuSections; 
    AssetManager assetManager; 
    String imageUrl; 

    public MenuAdapter(Context context, int resource, List<MenuSection> objects) { 
     super(context, resource, objects); 
     this.context = context; 
     this.menuSections = objects; 
     this.assetManager = context.getAssets(); 
    } 

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

    @Override 
    public MenuSection getItem(int i) { 
     return menuSections.get(i); 
    } 

    @Override 
    public long getItemId(int i) { 
     return menuSections.indexOf(getItemId(i)); 
    } 

    /* private view holder class */ 
    private class ViewHolder { 
     ImageView menuSectionImage; 
     TextView menuSectionItemText; 
    } 

    @Override 
    public View getView(int i, View view, ViewGroup viewGroup) { 
     ViewHolder holder = null; 


     LayoutInflater mInflater = (LayoutInflater) context 
       .getSystemService(Activity.LAYOUT_INFLATER_SERVICE); 
     if (view == null) { 
      view = mInflater.inflate(R.layout.menu_section, null); 
      holder = new ViewHolder(); 
      holder.menuSectionItemText = (TextView) view.findViewById(R.id.section_title); 
      holder.menuSectionImage = (ImageView) view.findViewById(R.id.section_bg_image); 

      view.setTag(holder); 
     } else { 
      holder = (ViewHolder) view.getTag(); 
     } 

     MenuSection menuSection = menuSections.get(i); 

     holder.menuSectionItemText.setText(menuSection.getSectionName()); 

     try { 
      imageUrl = menuSection.getImagePath(); 
      if (!MyUtility.isNullOrEmpty(imageUrl)) { 
       Picasso.with(holder.menuSectionImage.getContext()) 
         .load(Uri.parse(imageUrl)) 
         .into(holder.menuSectionImage); 
      } 
     } catch (Exception ex) { 
      ex.printStackTrace(); 

     } 

     return view; 
    } 
}

，这是片段RestaurantFragment.java

import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.AdapterView; 
import android.widget.ListView; 
import android.widget.Toast; 

import java.util.List; 

import com.myapp.hotel.MyUtility; 
import com.myapp.hotel.R; 


/**

*/ 
public class RestaurantFragment extends Fragment { 
    MenuAdapter adapter; 
    List<MenuSection> menuSections; 
    View view; 

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

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 
     if(view == null) { 
      view = inflater.inflate(R.layout.fragment_restaurant, container, false); 
     } 
     //adapter = new ArrayAdapter<String>(RestaurantFragment.this.getContext(), R.layout.menu_view, R.id.menu_text, MyUtility.getMenuSections().toArray(new String[MyUtility.getMenuSections().size()])); 
     ListView listView = (ListView) view.findViewById(R.id.menu); 
     menuSections = MyUtility.getMenuSections(); 

     adapter = new MenuAdapter(RestaurantFragment.this.getContext(), R.layout.menu_section, menuSections); 
     listView.setAdapter(adapter); 
     listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) { 
       Toast.makeText(RestaurantFragment.this.getActivity(), "Hello World", 
         Toast.LENGTH_SHORT).show(); 
      } 
     }); 
     //listView.setOnItemClickListener(); 
     //listView.setAdapter(adapter); 

     /* 
     listView.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
      @Override 
      public void onItemClick(AdapterView<?> parent, View view, 
            int position, long id) { 
       Intent intent = new Intent(RestaurantFragment.this.getContext(), RestaurantMenuDetailsActivity.class); 
       intent.putExtra("menu_section", adapter.getItem(position).toString()); 
       startActivity(intent); 
      } 
     }); 
     */ 
     return view; 
    } 
}

这是我在logcat中看到的错误

什么是我失踪/出错？

UPDATE

所有我的总重量〜400KB的图像。 8张图像，每张大约50Kb。问题是，即使我注释掉整个图像加载的东西，只是加载文本，点击任何列表视图项目时也会引发同样的错误。所以它绝对不是与图像有关。我认为适配器有问题..只是无法弄清楚它可能是什么！它只是一个简单的适配器！

MessageQueue听起来更像是一个处理程序泄漏。 –

我认为它与图像处理无关。这是由于无限递归导致的堆栈溢出getItemId()

@Override 
public long getItemId(int i) { 
    // calls itself with the same value, it can not end well ! 
    return menuSections.indexOf(getItemId(i)); 
}

OMG ..非常感谢你:) – Rohan

您可以在应用程序标签内的Android Manifest中使用largeheap="true"。但最好调整图片大小。

单张照片的高度，宽度是多少？
