I'm trying out Otto on Android and i'm trying to send back a message from my Fragment to the Activity. Here's the basics of my code:
My Bus provider:
public final class BusProvider {
private static final Bus mInstance = new Bus();
private BusProvider() {}
public static Bus getBusProviderInstance() {
return mInstance;
}
}
My Activity has the following code:
public class MyActivity
extends BaseActivity {
// ....
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
BusProvider.getBusProviderInstance().register(this);
// ....
}
@OnClick(R.id.profile_image)
public void onImageClicked() {
// ...
MyFragment fragment = MyFragment.newInstance(choices);
fragment.show(getFragmentManager(), "myChoices");
}
@Subscribe
public void onButtonChoicePicked(MyFragment.ChoicePickedEvent event) {
Toast.makeText(this, "reaching here", Toast.LENGTH_SHORT).show();
}
@Override
protected void onStop() {
super.onStop();
BusProvider.getBusProviderInstance().unregister(this);
}
// ...
}
and these are the important bits of code from my Fragment:
public class MyFragment
extends BaseDialogFragment {
// ...
@Override
public View onCreateView(LayoutInflater inflater,
ViewGroup container,
Bundle savedInstanceState) {
LinearLayout layout = (LinearLayout) inflater.inflate(R.layout.dialog_choices,
container,
false);
setupDialogButtons(inflater, layout);
return layout;
}
private void setupDialogButtons(LayoutInflater inflater, LinearLayout parentView) {
ChoiceButtonViewHolder holder;
holder = new ChoiceButtonViewHolder(inflater, parentView);
holder.populateContent("First Choice", 1);
parentView.addView(holder.mChoiceTextView);
}
class ChoiceButtonViewHolder {
@InjectView(R.id.item_dialog_choice_desc) TextView mChoiceTextView;
private int mPosition;
ChoiceButtonViewHolder(LayoutInflater inflater, ViewGroup container) {
TextView mChoiceTextView = (TextView) inflater.inflate(R.layout.item_dialog_choice, container, false);
ButterKnife.inject(this, mChoiceTextView);
}
public void populateContent(String choiceDesc, int position) {
mChoiceTextView.setText(choiceDesc);
mPosition = position;
}
@OnClick(R.id.item_dialog_choice_desc)
public void onChoiceClicked() {
MyFragment.this.mDialog.dismiss();
BusProvider.getBusProviderInstance().post(new ChoicePickedEvent(1));
}
}
public static class ChoicePickedEvent {
public int mPositionClicked;
ChoicePickedEvent(int position) {
mPositionClicked = position;
}
}
}
I don't get any errors. But when i click my button from the fragment, the event onButtonChoicePicked doesn't get called.
Am I doing something wrong? Am i misunderstanding how Otto works? Is it a weird combination of ButterKnife and Otto that makes it not work?
