I have two objects that needs callback implementation, what if both objects need different implementation? if i implement it at class level by implement keyword, interface methods only appear once in that activity, also If I'm calling both callback on the same object it only execute first callback, here is my code: same object but different implementation of interface method, in this case only the first callback executed that called first
client.setCallback(new MqttCallback() {
@Override
public void connectionLost(Throwable cause) {
}
@Override
public void messageArrived(String topic,
MqttMessage message) throws Exception {
}
@Override
public void deliveryComplete(IMqttDeliveryToken token) {
try {
MqttMessage message = token.getMessage();
} catch (MqttException e) {
e.printStackTrace();
}
}
});
same object different implementation:
client.setCallback(new MqttCallback() {
@Override
public void connectionLost(Throwable cause) {
}
@Override
public void messageArrived(String topic,
MqttMessage message) throws Exception {
tv.append(message.toString());
Log.i("MainActivity", " Mesages" + message);
}
@Override
public void deliveryComplete(IMqttDeliveryToken token) {
}
});
