java - Android calling class functions from second class -

how can call function defined in class#a class#b?

class#b extends aynchtask , fetches remote data web service. class#a function attempting call class#b used send retrieved remote data class#a display.

i trying pass current instance of class#a class#b using this passes context functions not recognized.

i tried using static function runs new thread, defining function static generates compiler error.

the code trying call follows:

public void test(list<data> data){         this.data = data;         runonuithread(new runnable() {                        @override             public void run() {                 // todo auto-generated method stub                 for(data data : mainactivity.this.data){                     toast.maketext(mainactivity.this, data.title, toast.length_short).show();                 }             }         });     } 

can me this?

this how it:

in mainactivity:

classbasynctask mat = new classbasynctask(this, .., ..); 

classbasynctask's contructor:

public classbasynctask(mainactivity context, .., ..) {     mcontext = context;     ....     .... } 

to call mainactivity's method test(list<data>) within classbasynctask:

((mainactivity)mcontext).test(yourlistvariable); 

look weak references make sure asynctask not use mcontext when activity no longer exists.
