 @override public view getview(final int position, view convertview, viewgroup parent) {      if (convertview == null){         convertview = layoutinflater.from(context).inflate(r.layout.item_list, parent, false);     }     final textview textview1 = (textview) convertview.findviewbyid(r.id.textview1);     final textview textview2 = (textview) convertview.findviewbyid(r.id.textview2);     final button show = (button) convertview.findviewbyid(r.id.show1);     final button hide = (button) convertview.findviewbyid(r.id.hide1);      textview1.settext(data[position]);      show.setonclicklistener(new view.onclicklistener() {         @override         public void onclick(view v) {             show.setvisibility(view.invisible);             hide.setvisibility(view.visible);              try{                  resources resources = getresources();                 assetmanager assetmanager = resources.getassets();                 string filelist[] = assetmanager.list("latest_trials");                  if (filelist != null){                     (int = 0; < filelist.length; i++){                         log.v("files", filelist[i]);                     }                 }                  inputstream inputstream;                     try{                         inputstream = assetmanager.open(filelist[position]);                         byte[] buffer = new byte[inputstream.available()];                         inputstream.read(buffer);                          string value = new string(buffer);                         textview2.setmaxlines(integer.max_value);                         textview2.setvisibility(view.visible);                         textview2.settext(value);                     }catch (ioexception e){                         e.printstacktrace();                     }              }catch (ioexception e){                 e.printstacktrace();             }           }     });

all files listing , want show content of file in textview in listview not reading files , showing filenotfoundexception. please 1 help..

once getview on position value become last value. if click point last value. tag position button settag() , in onclick gettag()

just debug , check, last value of filelist[].

do this- 

show.settag(position)  show.setonclicklistener(new view.onclicklistener() {     @override     public void onclick(view v) {          int pos = integer.parseint(v.gettag());

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
