Yes, you can. Use a WeakReference to your activity.
static class MyHandler extends Handler {
private WeakReference<MyActivity> activityRef;
public MyHandler(MyActivity activity) {
activityRef = new WeakReference<MyActivity>(activity);
}
/**
* @return The activity for which this MyHandler was created.
* Returns null if this activity is no longer there (i.e. was garbage
collected).
*/
MyActivity getActivity() {
return activityRef.get();
}
}
Then, you do simHandler= new MyHandler(this);
and when you need the activity:
MyActivity ac = simHandler.getActivity();
if (ac != null) }
....
....
}
