Second question of the day! (Sorry, Newbie)
I'm trying to create a separate thread, and in that thread I need to be able to send information back to the UI thread. For this, I went ahead and created a new Handler Class:
private static class nHandler extends Handler{
private final WeakReference<MainActivity> mTarget;
public nHandler(MainActivity context){
mTarget = new WeakReference<MainActivity>((MainActivity) context);
}
@Override
public void handleMessage(Message msg){ Log.d("Something", "It got here")}
}
In my main activity class I have a private static nHandler mHandler; I then created a handler in my onCreate() using mHandler = new nHandler(this);
When I create my other thread, and it runs I create a handler object and set it to the one I passed in the constructor. In this other class I then have a function:
private synchronized void setState(int state){
//lets add some logging
mState = state;
//Give the handler something so the Main Activity Updates
mHandler.obtainMessage(MainActivity.HANDLER_CHANGE_SERVER_STATUS, state, -1);
}
But in the Log I don't see my log come up. I may not completely understand how handlers are supposed to work, so if you think that is the case can you help me understand them and get it working right?
Thanks!
