I am following this tutorial to create my project using MQTT protocol:



https://wildanmsyah.wordpress.com/2017/05/11/mqtt-android-client-tutorial/



But, I want to know how can I subscribe different messages from different topics in others textview. For example:



message1 from topic1 to textview1,
message2 from topic2 to textview2,
message3 from topic3 to textview3...
I want to create different textview with different messages from different topics .



Thanks for all! =)



In my MQTTHelper.java:



private void subscribeToTopic() {
try {
mqttAndroidClient.subscribe(subscriptionTopic, 0, null, new IMqttActionListener() {
@Override
public void onSuccess(IMqttToken asyncActionToken) {

}

@Override
public void onFailure(IMqttToken asyncActionToken, Throwable exception) {

}
});


}

catch (MqttException ex) {
System.err.println("Exception whilst subscribing");
ex.printStackTrace();
}

try {
mqttAndroidClient.subscribe(subscriptionTopic2, 0, null, new IMqttActionListener() {
@Override
public void onSuccess(IMqttToken asyncActionToken) {

}

@Override
public void onFailure(IMqttToken asyncActionToken, Throwable exception) {

}
});


}

catch (MqttException ex) {
System.err.println("Exception whilst subscribing");
ex.printStackTrace();
}

}


In my MainActivity:



 private  void startMqtt(){

mqttHelper = new MQTTHelper(getApplicationContext());
mqttHelper.setCallback(new MqttCallback() {
@Override
public void connectionLost(Throwable cause) {

}

@Override
public void messageArrived(String topic, MqttMessage message) throws Exception {
textReceive.setText(message.toString());
}



@Override
public void deliveryComplete(IMqttDeliveryToken token) {

}
});


mqttHelper2 = new MQTTHelper(getApplicationContext());
mqttHelper2.setCallback(new MqttCallback() {
@Override
public void connectionLost(Throwable cause) {

}

@Override
public void messageArrived(String topic, MqttMessage message) throws Exception {
textReceive2.setText(message.toString());
}

@Override
public void deliveryComplete(IMqttDeliveryToken token) {

}
});


}
