Solution 1:

Why not pass your own callback from activity to MyLocationListener and call its method from finishTracking?

Its a commonly used delegation pattern. Something like that:

classMyLocationListenerimplementsLocationListener {
    publicinterfaceMyListener {
        voidonLocationReceiver( Location location );
    }

    private MyListener listener;

    publicMyLocationListener(Context context, ProgressDialog dialog, MyListener listener) {
        mContext = context;
        progressDialog = dialog;
        this.listener = listener;
    }

    privatevoidfinishTracking(Location location) {
        if(location != null) {
            locationManager.removeUpdates(this);
            progressDialog.hide();
            Log.i("TRACKING",location.toString());
            listener.onLocationReceiver(location);
        }
    }
}

and call:

new MyLocationListener(this, dialog, new MyLocationListener.MyListener() {
    public void onLocationReceived( Location location ) {
        text.setText(location.toString());
    }
}).startTracking();

Solution 2:

You can do another simple thing - put your class MyLocationListener inside your Activity itself and modify the field in your activity inside your MyLocationListener itself.
