how to show listview itemclick image into the alertbox using android json?

onItemClick use position to get clicked row HashMap from arraylist :

HashMap<String, String> map =arraylist.get(position);

Get clicked row name and image URL from map and show it in AlertDialog as doing in getView() method of ListViewAdapter

                    onBackPressed();
                    returntrue;
                default:
                    returnsuper.onOptionsItemSelected(item);
            }
        }
    }

It's the solution. Try this.

hi i gt the solution here:

publicvoidonItemClick(AdapterView<?> parent, View view,
                                int position, long rowId) {

            finalAlertDialogcustomDialog=newAlertDialog.Builder(SubMenu.this).create();
            finalLayoutInflaterinflater= getLayoutInflater();
            finalViewdialogView= inflater.inflate(R.layout.popup
                    , null);
            customDialog.setView(dialogView);
            HashMap<String, String> map =arraylist.get(position);
            ImageViewimage= (ImageView) dialogView.findViewById(R.id.desimage);
            ImageLoaderimageLoader=newImageLoader(SubMenu.this);
            imageLoader.DisplayImage(map.get(SubMenu.FLAG), image);

            //  crust.setOnItemSelectedListener(this);// public void addListenerOnSpinnerItemSelection() {finalButtonok= (Button) dialogView.findViewById(R.id.ok);
            ok.setOnClickListener(newView.OnClickListener() {

                @OverridepublicvoidonClick(View v) {

                    customDialog.dismiss();


                }
            });


            finalButtoncncl= (Button) dialogView.findViewById(R.id.canc);
            cncl.setOnClickListener(newView.OnClickListener() {

                }
