            } 
        }); 
    }
}

Answer 1

You can use either performClick() or callOnClick()

performClick()

Added in API level 1.
Call this view's OnClickListener if it is defined. Performs all normal actions associated with clicking: reporting accessibility event, playing a sound, etc.

callOnClick()

Added in API level 15. Directly call any attached OnClickListener. Unlike performClick, this only calls the listener, and does not do any associated clicking actions like reporting an accessibility event.

imerTask timerTask = new TimerTask() {
@Override
public void run() {
btnrefres.performClick();
}
};
Timer timer = new Timer();
timer.schedule(timerTask, 0, 5000);

Second option is: Add all your soap services in a function. Later call the function in setonclicklistener and in the timertask run().

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

btnrefres.setOnClickListener(new View.OnClickListener(){
soapservice();
}
}

TimerTask timerTask = new TimerTask() {
@Override
public void run() {
soapservice();
}
};
Timer timer = new Timer();
timer.schedule(timerTask, 0, 5000);


soapservice(){
**//I've done operations**
}
