 imageview targetimage = (imageview) findviewbyid(r.id.stud_list_image);     private void populatefields()  {         cursor data = studentsdbadapter.queuepic();        if (data.movetofirst()) {            cursoradapter = new simplecursoradapter(this, r.layout.stud_row,  data, new string[] {studentsdbadapter.key_imagepathid, studentsdbadapter.key_imagepath}, new int[] {r.id.textstud,r.id.stud_list_image});            simplecursoradapter.viewbinder viewbinder = new simplecursoradapter.viewbinder() {                public boolean setviewvalue(view view, cursor cursor, int columnindex) {                    if(view != null && view.getid() != r.id.stud_list_image) {                        return false;                    }                string username = cursor.getstring(cursor.getcolumnindex(studentsdbadapter.key_imagepathid));                string path =  logindatabaseadapter.getimapath(username);                file image = new  file(path);                 ((imageview)view).setimagebitmap(bitmapfactory.decodefile(image.getabsolutepath()));          ;               return true;                }            };            int index = data.getcolumnindex(studentsdbadapter.key_imagepath);            //log.d(constants.tag, "" + index);            cursoradapter.setviewbinder(viewbinder);            viewbinder.setviewvalue(targetimage, data, index);            listcontent.setadapter(cursoradapter);        }          }

updated question, here logcat:

update

i tried test using following code: 

cursor data = studentsdbadapter.queuepic();        if (data.movetofirst()) {            cursoradapter = new simplecursoradapter(this, r.layout.stud_row,  data, new string[] {studentsdbadapter.key_imagepathid, studentsdbadapter.key_imagepath}, new int[] {r.id.textstud,r.id.stud_list_image});            simplecursoradapter.viewbinder viewbinder = new simplecursoradapter.viewbinder() {                public boolean setviewvalue(view view, cursor cursor, int columnindex) {                    if(view != null && view.getid() != r.id.stud_list_image) {                        return false;                    }                string username = cursor.getstring(cursor.getcolumnindex(studentsdbadapter.key_imagepathid));                // string path =  studentsdbadapter.getimapath("101-00017");               // file image = new  file(path);                 bitmap imagenandroid = bitmapfactory.decoderesource(getresources(),r.drawable.ic_launcher);                targetimage.setimagebitmap(imagenandroid);                    return true;                     }              };            int index = data.getcolumnindex(studentsdbadapter.key_imagepath);            //log.d(constants.tag, "" + index);            cursoradapter.setviewbinder(viewbinder);            viewbinder.setviewvalue(targetimage, data, index);            listcontent.setadapter(cu

rsoradapter);

it still give error at

viewbinder.setviewvalue(targetimage, data, index);

replace

((imageview)view).setimagebitmap(bitmapfactory.decodefile(image.getabsolutepath()));

with

targetimage.setimagebitmap(bitmapfactory.decodefile(image.getabsolutepath()));

i've been working on making 2d map editor past 2 weeks or so, , i've run strange problem. trying optimize code, example, making functions should've been functions begin with, did made cpu usage go through roof. i've tried commenting out different sections of code thought culprits (scrolling, rendering, other calculations) no avail. think issue might trying call things within different functions, sake of making modular possible, i'd functionality. the other major change i've made since file i'm comparing i've ported variables external cpp file, since having variables global makes lot easier use within different functions. simple issue, can't life of me understand why happens. with original code, around 2-3% cpu usage. new code, around 20-35%, but, if move mouse around, it'll drop around 6-8%. tl;dr: after trying optimize code using functions, i've somehow killed performance, , found strange quirk moving mouse reduces cpu usage.. /...
