이미지가 메모리 부족 상태 인 listView에 대한 사용자 정의 ArrayAdapter

Question

XML 파일에서 데이터를 표시하려고하는데 정보를 목록으로 구문 분석하는 클래스를 만들었으므로 각 항목의 그림과 tostring을 표시해야합니다. 사용자 지정 ArrayAdapter를 만들었습니다.

import android.app.Activity; 
import android.content.Context; 
import android.graphics.drawable.Drawable; 
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 java.util.List; 

/**

*/ 
public class CustomListViewAdapter extends ArrayAdapter<Meal> { 


    Context context; 

    public CustomListViewAdapter(Context context, int resourceId, //resourceId=your layout 
           List<Meal> items) { 
     super(context, resourceId, items); 
     this.context = context; 
    } 

    /*private view holder class*/ 
    private class ViewHolder { 
     ImageView imageView; 
     TextView txtTitle; 
    } 

    public View getView(int position, View convertView, ViewGroup parent) { 
     ViewHolder holder = null; 
     Meal rowItem = getItem(position); 

     LayoutInflater mInflater = (LayoutInflater) context 
       .getSystemService(Activity.LAYOUT_INFLATER_SERVICE); 
     if (convertView == null) { 
      convertView = mInflater.inflate(R.layout.list_item, null); 
      holder = new ViewHolder(); 
      holder.txtTitle = (TextView) convertView.findViewById(R.id.title555); 
      holder.imageView = (ImageView) convertView.findViewById(R.id.icon555); 
      convertView.setTag(holder); 
     } else 
      holder = (ViewHolder) convertView.getTag(); 

     holder.txtTitle.setText(rowItem.toString()); 
     if(rowItem.getPicPath().compareTo("") != 0) 
      holder.imageView.setImageDrawable(Drawable.createFromPath(rowItem.getPicPath())); 

     return convertView; 
    } 
} 

이 활동입니다 :

import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.view.Menu; 
import android.widget.ArrayAdapter; 
import android.widget.ListView; 

import java.io.File; 
import java.io.FileInputStream; 
import java.io.IOException; 
import java.util.List; 

public class XmlPullParser extends AppCompatActivity { 

     ListView listView; 

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

      listView = (ListView) findViewById(R.id.list); 

      List<Meal> meals = null; 
      try { 
       XMLPullParserHandler parser = new XMLPullParserHandler(); 
       meals = parser.parse(getStringFromFile(Globals.xmlFilePath)); 
       CustomListViewAdapter adapter = 
         new CustomListViewAdapter(this,R.layout.list_item, meals); 
       listView.setAdapter(adapter); 
      } catch (IOException e) { 
       e.printStackTrace(); 
      } catch (Exception e) { 
       e.printStackTrace(); 
      } 
     } 


    public static FileInputStream getStringFromFile (String filePath) throws Exception { 
     File fl = new File(filePath); 
     FileInputStream fin = new FileInputStream(fl); 
     return fin; 
    } 
}

로드하는 이미지의 크기가 OutOfMemoryError이거나, Loading Large Bitmaps Efficiently이거나, 이미지로드 프레임 워크 (예 : Picasso 또는 Glide)로 전환 될만큼 충분히 큽니다.
