Listview顯示垃圾值

嗨，我正在做示例項目，因爲我有像listitem這樣的問題顯示一些垃圾值。不知道如何解決。誰能幫我嗎。Listview顯示垃圾值

這是我的活動：

public class MainActivity extends Activity { 
ListView app_List; 
private ArrayList<AppInfo> infoList; 
private ArrayAdapter<AppInfo> adpt; 
@SuppressWarnings("unchecked") 
@Override 
public void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.activity_main); 
    app_List = (ListView)findViewById(R.id.listView1); 
    infoList = getListOfUserInstalledApps(); 
    } 

    private ArrayList<AppInfo> getListOfUserInstalledApps() { 
    // TODO Auto-generated method stub 
    List<PackageInfo> apps = getPackageManager().getInstalledPackages(0); 
    System.out.println("No. of applications installed on the device: "+apps.size()); 
    ArrayList<AppInfo> infoList1 = new ArrayList<AppInfo>(); 
    for(int i=0;i<apps.size();i++) {   
     PackageInfo p = apps.get(i);   
     /*if ((!getSysPackages) && (p.versionName == null)) {  
      continue ;  }*/ 

     AppInfo info = new AppInfo(); 
     //info.appname = p.applicationInfo.loadLabel(getPackageManager()).toString(); 
     info.pname = p.packageName; 
     System.out.println("application name: "+info.pname); 
     //info.pname = p.packageName; 
     infoList1.add(info); 

    } 
    return infoList1; 
} 
static class AppInfo { 
    //private String appname = "";  
    private String pname = "";  
    //private String versionName = "";  
    //private int versionCode = 0;  
    //private Drawable icon; 

} 


@Override 
protected void onResume() { 
    // TODO Auto-generated method stub 
    super.onResume(); 
    adpt = new ArrayAdapter<AppInfo>(this,android.R.layout.simple_list_item_1, infoList); 
    app_List.setAdapter(adpt); 

} 
}
