Hello, I use my Main Activity to paint Text. Now Ive a Service in
Background that listens to a bluetooth device. If a button on the
device is pressed I insert values in the local database and want to
repaint the correct value in my Main Activity. Everything works fine -
just the repaint does not work, because i cant call the invalidate()
method from my Service.
I tried with a BroadCastReceiver but i think i misunderstood
something.
----------
This is my Method in my Service "ControllerService"
private void insertToDB(int iWert, char c) {
if(zt.getJoystickMoved().x == iWert) {
sendOrderedBroadcast(i,null);
Log.i("Broadcast","send!");
//in this block i want to notify the Activity
}
}
----------
Here is my Main Activity
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
registerReceiver(resetReceiver, new
IntentFilter("my.intent.INTENT_NAME"));
}
public BroadcastReceiver resetReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
Log.i("Broadcast", "got Broadcast!");
MainActivity.this.cc.invalidate();
//cc.invalidate() repaints my Activity
//cc is a View with the paint Logic inside
this.setResultCode(Activity.RESULT_OK);
}
}
My Broadcast Receiver in my Main Activity does not receive
anything ...
I hope someone could help me with my Problem.
