android - Notifying adapter from model -


i'm trying make changes android application adopting mvp pattern, i'm having trouble notify adapter recyclerview using.

what i'm doing giving reference adapter in model , notifying changes made when click events happen, so: 

public class mymodel {      private myadapter adapter;     ...     public void setadapter(myadapter adapter) { this.adapter = adapter; }      public void action() {         // make changes model , notify adapter changes          // made individual items         ...         adapter.notifyitemchanged(position)     } }

i'm wonder conventional way of handling kind of behaviour using mvp pattern.

the observer pattern might looking for. when changes made model can notify observers (the presenters) can update view.

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
