使用lazyAdapter

困惑我想在本教程中使用lazyAdapter： http://www.androidhive.info/2012/02/android-custom-listview-with-image-and-text/使用lazyAdapter

但在本教程中使用XMLPARSER，我想使用JSON，所以我很困惑尤其我是初學者

你能幫我請用JSON替換XML嗎？

package com.fedorvlasov.lazylist; 

import android.app.Activity; 
import android.content.Context; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.BaseAdapter; 
import android.widget.ImageView; 
import android.widget.TextView; 

public class LazyAdapter extends BaseAdapter { 

    private Activity activity; 
    private String[] data; 
    private static LayoutInflater inflater=null; 
    public ImageLoader imageLoader; 

    public LazyAdapter(Activity a, String[] d) { 
     activity = a; 
     data=d; 
     inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     imageLoader=new ImageLoader(activity.getApplicationContext()); 
    } 

    public int getCount() { 
     return data.length; 
    } 

    public Object getItem(int position) { 
     return position; 
    } 

    public long getItemId(int position) { 
     return position; 
    } 

    public View getView(int position, View convertView, ViewGroup parent) { 
     View vi=convertView; 
     if(convertView==null) 
      vi = inflater.inflate(R.layout.item, null); 

     TextView text=(TextView)vi.findViewById(R.id.text);; 
     ImageView image=(ImageView)vi.findViewById(R.id.image); 
     text.setText("item "+position); 
     imageLoader.DisplayImage(data[position], image); 
     return vi; 
    } 
}
