Java – greenroot eventbus failed to send event

I'm using eventbus to pass from a long-running thread to fragments that update its UI This long - running thread is basically listening for network activity, parsing it and putting events on the bus I have 2 clips set to receive events

An error occurred when I updated the fragments UI (textview) from the fragments onevent method How do I update the UI in a fragment from a separate thread?

This is my snippet code and the logcat output I see

Of logcat:

This is a fragment (they look the same):

public class OneUpScreen extends ScreenFragment {   
    private Button name;
    private TextView c00Title,c00Data;

    //DEBUG
    public String title;

    //DEBUG
    private int counter = 0;

    //for logging and convenience
    private static final String TAG = "BRRT";   


    @Override
    public void onResume(){
        super.onResume();
        EventBus.getDefault().registerSticky(this);
    }

    @Override
    public void onPause(){
        EventBus.getDefault().unregister(this);
        super.onDestroy();
    }

    //process the bus messaging
    public void onEvent(ExpeditionEvent event){
        Log.v(TAG,"OneUp event received: " + event.getEventId() + " : " + event.getEventScreenValue());

        c00Data = (TextView) getView().findViewById(R.id.c00Data);
        c00Data.setText(counter);

        counter++;
    }


    @Override
    public View onCreateView(LayoutInflater inflater,ViewGroup container,Bundle savedInstanceState) {
        View v = inflater.inflate(R.layout.one_up_screen_layout,container,false);

        name = (Button) v.findViewById(R.id.lblTitle);
        c00Title = (TextView) v.findViewById(R.id.c00Title);
        c00Data = (TextView) v.findViewById(R.id.c00Data);

        Bundle bundle = this.getArguments();

        //initial set up of the text on the screen
        //null check
        name.setText((bundle.getString("name") == null) ? "error" : bundle.getString("name"));
        c00Title.setText((bundle.getString("c00Title") == null) ? "error" : bundle.getString("c00Title"));
        title = bundle.getString("c00Title");

        return v;
    }

    public OneUpScreen(){

    }

    public static OneUpScreen newInstance() {
        OneUpScreen frag = new OneUpScreen();
        return frag;
    }

    //attach the config for this instance.
    @Override
    public void setConfig(ScreenConfig sc){
        //set up the data to paint the screen for the first time
        Bundle b = new Bundle();

        //Now we have to parse some stuff into a bundle and send the bundle to the fragment
        b.putString("name",sc.getName());
        b.putString("c00Title",sc.getEvents().get(0).getCleanName());
        b.putInt("c00Data",sc.getEvents().get(0).getEventID());

        //pass it along
        this.setArguments(b);
    }


    @Override
    public void update(SparseArray<String> sensorDataMap) {
        Log.v(TAG,"OneUp Update called: " + counter);
        counter++;
    }
}

The onevent method is where I look here This method is called if you notice in the log However, I can't click on its internal textview Initially, I just referenced textview in the oncreate () method But I saw an example, you look at it again in event handling, so I turned to that, no luck

If I take out:

c00Data.setText(counter);

Then the valgus effect is very good

What did I miss here?

Solution

Well, for later people here, this is my way to solve this problem

It turns out that the key error I see is not an event - related error, but a resource - related error

10-15 02:19:45.271: W/ResourceType(682): No package identifier when getting value for resource number 0x00000000

I looked at so elsewhere and found this:

No package identifier when getting value for resource number

Then I go back to my code and rewrite textview The settext () call looks different

Old mode (counter is an int):

c00Data.setText(counter);

new method:

c00Data.setText(""+counter);

I did I shouted
