Android custom apps list

In my project, I wanted to list apps installed on my Android device.
But it should be custom list with icons.


For this purpose, I used the following code:

public class Main extends ListActivity {
	private String xmlResponse;
	 private String error;
	 static final ArrayList> list_arr =
 		new ArrayList>();
	 private PackageManager pm;
	 private String version;
	 
	 private void PopulateList ()
	 {
		 
		 Intent intent = new Intent(Intent.ACTION_MAIN, null);
		  intent.addCategory(Intent.CATEGORY_LAUNCHER);
		 List list = pm.queryIntentActivities(intent, PackageManager.PERMISSION_GRANTED);
		 
		 list_arr.clear();
		 int i = 0;
		  for (ResolveInfo rInfo : list) {
			  String package1 = rInfo.activityInfo.applicationInfo.packageName;
			  PackageInfo pInfo;
			  version = ""; 
			try {
				pInfo = getPackageManager().getPackageInfo(package1, PackageManager.GET_META_DATA);
				version = pInfo.versionName;
			} catch (NameNotFoundException e) {
				// TODO Auto-generated catch block
				e.printStackTrace();
			}
		      
			  String name1 = rInfo.activityInfo.applicationInfo.loadLabel(pm).toString();
			  Drawable icon = rInfo.activityInfo.applicationInfo.loadIcon(pm);
			  		   
			  i++;
		 
			  HashMap temp = new HashMap();
	   	   temp.put("name",name1);
	       temp.put("value",package1);
	       temp.put("value_bottom",version);
	       temp.put("image", icon);
	       list_arr.add(temp);
	       
		  } 
	 }
		  
	 
	 @Override
	 public void onCreate(Bundle savedInstanceState) {
	  super.onCreate(savedInstanceState);
	  pm = this.getPackageManager();
	  myAdapter adapter = new myAdapter(
			  this, 
			  list_arr,
              R.layout.main, 
              new String[] {"name","value","value_bottom","image"},
	    	    new int[] {R.id.option_name,R.id.option_value,R.id.option_value_bottom,R.id.icon}
	    	    );
	  PopulateList();
	  setListAdapter(adapter);
	 }
	 
	 private class myAdapter extends SimpleAdapter {

	        public myAdapter(Context context, List> data,
	                int resource, String[] from, int[] to) {
	            super(context, data, resource, from, to);

	        }

	        @Override
	        public View getView(int position, View convertView, ViewGroup parent) {

	            if (convertView == null) {
	                convertView = getLayoutInflater().inflate(R.layout.main,
	                        null);
	            }

	            HashMap data = (HashMap) getItem(position);

	            ((TextView) convertView.findViewById(R.id.option_name))
	                    .setText((String) data.get("name"));
	            ((TextView) convertView.findViewById(R.id.option_value))
                		.setText((String) data.get("value"));
	            ((TextView) convertView.findViewById(R.id.option_value_bottom))
                		.setText((String) data.get("value_bottom"));
	            ((ImageView) convertView.findViewById(R.id.icon))
	                    .setImageDrawable((Drawable) data.get("image"));

	            return convertView;
	        }

	    }

main.xml file should look as following:
