java - Trying to pass data from ListView to another class -

So I got stuck on it for hours. I am trying to set up an async job that will load images for my listview in another category and I am passing information that gives me an error

Any help would be appreciated!

increases public class results activity {

  public static final string DEFAULTNAME = "DefaultFile"; Private GETTHEIMAGE imgFetch; Private Arrest & amp; Lt; Item_Info & gt; Info = New Arrestist & lt; Item_info & gt; (); String data = null; String threshold = null; TextView httpStuff; @ Override protected void saved create (bundled Instansstet) {Suprknkret (saved Instensstet); // Full Screen Request WindowFeature (Window.FEATURE_NO_TITLE); GetWindow () Set Flag (WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); SetContentView (R.layout.theresults); SharedPreferencesSearch = getSharedPreferences (DEFAULTNAME, 0); Data = search .getString ("Thrasults", blank); Information (); Populatelist (); } Private Zero GetINFO () {}}} Private Zero Populatist () {Array Adapter & lt; Item_info & gt; Adapter = new TheListAdapter (); List View List = (List View) ViewById (R.id.listings); List.findFocus (); List.getWindowToken (); List.setAdapter (adapter); } Public class TheListAdapter ArrayAdapter and lt; Item_Info & gt; {Public TheListAdapter () {Super (The results .a, R.Let.Items, Info); } @ Override public view getView (see the status of int, seeviewview, ViewGroup parent) {see item_View = convertView; ImageHolder holder = null; If (item_view == faucet) {item_view = getLayoutInflater (). Flowers (R. Lateite. Items, Parents, False); Item_Info current item = Info.get (status); Holder = new picture holder (); Holder. ICNiG = (image view) item_view.findvibid (RID.Con_Is); Holder.ICON_IMG.setTag (CurrentItem.getItemPIC ()); Drawable MYIMG = imgFetch.GetTheImagedata (this, holder. ICON_IMG); Holder .ICON_TITLE = (TextView) item_View.findViewById (R.id.icon_title); Holder.ICON_TITLE.setText (CurrentItem.getItemTITLE ()); Holder .ICON_LOCATION = (TextView) item_View.findViewById (R.id.icon_location); Holder.ICON_LOCATION.setText (CurrentItem.getItemLOCATION ()); Holder .ICON_PRICE = (TextView) item_View.findViewById (R.id.icon_price); If (CurrentItem.getItemPRICE () == faucet) {holder.ICON_PRICE.setText (CurrentItem.getItemPRICE ()); Holder.ICON_PRICE.setBackgroundResource (R.drawable.tempbg); } Other {holder .ICON_PRICE.setBackgroundResource (R.drawable.pricebg); Holder.ICON_PRICE.setText (CurrentItem.getItemPRICE ()); } Holder. ICNDET = (text view) item_view.findvibidid (rid.con_date); Holder.ICON_DATE.setText (CurrentItem.getItemLOCATION ()); } Else {holder = (ImageHolder) item_View.getTag (); } Return item_view; }} Fixed square image holder {ImageView ICON_IMG; TextView ICON_TITLE; TextView ICON_LOCATION; TextView ICON_PRICE; TextView ICON_DATE; }   
}   
 
 
 After looking at the logs after the line   06-21 19: 15: 06.887: E / Android Random (11408): Fatal exception: main   
 is an exception  
 < Code> java.lang.NullPointerException   
 which tells us that something is  null  and it is throwing exceptions if we search the first line of code that When you reference your project, we will see where the problem is. Here, this logcat has the next line  
  com.clistc.TheResults tells us at $ TheListAdapter.getView (TheResults.java:178)   
 That line is 178's  TheResults.java  and it is within the  getView ()  method. We have established that this line is  
  DREAM MYIMG = imgFetch.GetTheImagedata (this, holder. ICON_IMG);   
 means that  imgFetch  is probably  null  and you try to call the function which is  null < / Code> because variable  is zero  I do not know what that variable is, but it is not being initialed before this line  
  edit   
  imgFetch is not started anywhere  
  Private Getimage IMGafet;   
 But you do not start it at any time by giving it a price. You need to do something like this  
  private GETTHEIMAGE imgFetch = new GETTHEIMAGE ();   
 Assume that there is an empty constructor in it
