Pass values to tab fragment

Question

I have two tabs in a FragmentTabHost - and my question is how can I pass data to the selected fragment?

Here is my code:

mTabHost.addTab(mTabHost.newTabSpec("clips").setIndicator(("Clips")),
                MyClipsFragment.class, null);
        mTabHost.addTab(mTabHost.newTabSpec("clipboards").setIndicator("Clipboards"),
                FragmentSearchMyClipboards.class, null);

in the bundle (3ed parameter)

Bundle myBundle = new Bundle()
myBundle.putInt("paramKey", 1);
mTabHost.addTab(mTabHost.newTabSpec("clips").setIndicator(("Clips")),
                MyClipsFragment.class, myBundle);

It complains about the last parameter being a bundle? – user1007522 Mar 03 '16 at 13:05

Actually the problem comes down to communicate between two fragments. The only way is through the activity which holds both the fragment. This can be done via declaring one interface in both the fragments and implementing them in the activity. Try to read here http://developer.android.com/training/basics/fragments/communicating.html

The easiest way to communicate through fragments is using EventBus - https://github.com/greenrobot/EventBus

HowTo: 1. Add these line to fragment that needs to get the information:

@Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
        EventBus.getDefault().register(this);
        return inflater.inflate(R.layout.event_list, container, false);

    }

@Override
    public void onDestroyView() {
        super.onDestroyView();
        EventBus.getDefault().unregister(this);
    }
public void onEventMainThread(EventBusMsg bus) { //Name your method like this   
        //here you get the info...
    }

2. Post the information from anywhere, like this:

EventBus.getDefault().post(new EventBusMsg(true));

Make class of the object you are going to post:
```
public class EventBusMsg {
```
//some info... }
