Android Comment modifier le menu de la barre d'actions à partir de Fragment

Question

J'ai créé une application qui utilise Fragment. Depuis ma MainActivity, j'ai défini l'ActionBar.

Mais dans l'un de mes fragments, je dois modifier les icônes d'action et cliquer.

Donc, avec le code ci-dessous, lorsque je charge mon fragment, il affiche toujours le menu de la barre d'action de MainActivity

voici ma MainActivity:

public void restoreActionBar() {
    actionBar.setNavigationMode(ActionBar.NAVIGATION_MODE_STANDARD);
    actionBar.setDisplayShowTitleEnabled(true);
    actionBar.setTitle(mTitle);

    // enable ActionBar app icon to behave as action to toggle nav drawer
    actionBar.setDisplayHomeAsUpEnabled(true);
    actionBar.setHomeButtonEnabled(true);

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    if (!mNavigationDrawerFragment.isDrawerOpen()) {
        // Only show items in the action bar relevant to this screen
        // if the drawer is not showing. Otherwise, let the drawer
        // decide what to show in the action bar.
        getMenuInflater().inflate(R.menu.main, menu);


        //Handle the Search Menu
        SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.action_search));
        searchView.setQueryHint(this.getString(R.string.action_search));

        ((EditText)searchView.findViewById(Android.support.v7.appcompat.R.id.search_src_text))
        .setHintTextColor(getResources().getColor(R.color.white));      
        searchView.setOnQueryTextListener(OnQuerySearchView);

        mSearchCheck = false;


        restoreActionBar();
        return true;
    }

    return super.onCreateOptionsMenu(menu);
}//end onCreateOptionsMenu

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle presses on the action bar items
    switch (item.getItemId()) {

        /** CAMERA **/
        case R.id.action_camera:
            //openCamera();
            Utils.makeToast(getApplicationContext(), "Implement Camera", false);
            return true;

        /** SEARCH **/   
        case R.id.action_search:
            //openSearch();
            mSearchCheck = true;
            Utils.makeToast(getApplicationContext(), "Implement Search", false);
            return true;

        /** SETTINGS **/ 
        case R.id.action_settings:
            //openSettings();
            Utils.makeToast(getApplicationContext(), "Implement Settings", false);
            return true;

        /** ABOUT **/ 
        case R.id.action_help:
            //openHelp();
            Utils.makeToast(getApplicationContext(), "Implement Help", false);
            return true;


        default:
            return super.onOptionsItemSelected(item);
    }//end switch
}//end onOptionsItemSelected

private OnQueryTextListener OnQuerySearchView = new OnQueryTextListener() {
    @Override
    public boolean onQueryTextSubmit(String arg0) {
        // TODO Auto-generated method stub
        return false;
    }
    @Override
    public boolean onQueryTextChange(String arg0) {
        // TODO Auto-generated method stub
        if (mSearchCheck){
            // implement your search here
        }
        return false;
    }
};//end OnQueryTextListener

Voici la mise en page:

<menu xmlns:Android="http://schemas.Android.com/apk/res/Android"
    xmlns:app="http://schemas.Android.com/apk/res-auto"
    xmlns:tools="http://schemas.Android.com/tools"
    tools:context="com.example.sellbeesclean.MainActivity" >


    <!-- CAMERA -->
    <item
        Android:id="@+id/action_camera"
        Android:orderInCategory="100"
        Android:icon="@drawable/ic_action_camera"
        Android:title="@string/action_camera"
        app:showAsAction="ifRoom|collapseActionView"/>

    <!-- SEARCH -->
    <item
        Android:id="@+id/action_search"
        Android:orderInCategory="100"
        Android:icon="@drawable/ic_action_search"
        Android:title="@string/action_search"
        app:actionViewClass="Android.support.v7.widget.SearchView"
        app:showAsAction="ifRoom|collapseActionView"/>

    <!-- SETTINGS -->
    <item
        Android:id="@+id/action_settings"
        Android:orderInCategory="100"
        Android:title="@string/action_settings"
        app:showAsAction="never"/>

    <!-- HELP -->
    <item
        Android:id="@+id/action_help"
        Android:orderInCategory="100"
        Android:icon="@drawable/ic_action_help"
        Android:title="@string/action_help"
        app:showAsAction="ifRoom|collapseActionView"/> </menu>

Elle est mon fragment:

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        setHasOptionsMenu(true);
        View rootView = inflater.inflate(R.layout.user_profile_fragment, container, false);
        Log.i(TAG, "onCreateView");
.....

    @Override
    public void onAttach(Activity activity) {
        super.onAttach(activity);

        setHasOptionsMenu(true);
    }

    @Override
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
        super.onCreateOptionsMenu(menu, inflater);      
        inflater.inflate(R.menu.fragment_menu, menu);

    }   



    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        // Handle presses on the action bar items
        switch (item.getItemId()) {

            /** EDIT **/
            case R.id.action_edit:
                //openEditProfile(); //Open Edit Profile Fragment
                Utils.makeToast(MyApplication.getAppContext(), "Implement Camera", false);
                return true;



            default:
                return super.onOptionsItemSelected(item);
        }//end switch
    }//end onOptionsItemSelected

ici la disposition du menu fragment

<menu xmlns:Android="http://schemas.Android.com/apk/res/Android"
    xmlns:app="http://schemas.Android.com/apk/res-auto"
    xmlns:tools="http://schemas.Android.com/tools"
    tools:context="com.example.sellbeesclean.MainActivity" >


    <!-- EDIT -->
    <item
        Android:id="@+id/action_edit"
        Android:orderInCategory="100"
        Android:icon="@drawable/ic_action_edit"
        Android:title="@string/action_edit_profile"
        app:showAsAction="ifRoom|collapseActionView"/></menu>

Answer 1

Dans la méthode onCreateView de votre fragment, écrivez

setHasOptionsMenu(true);

Et gonflez votre fichier XML de menu dans la méthode onCreateOptionsMenu

Dans onCreateOptionsMenu d'un fragment, écrivez

menu.clear();

avant de gonfler les menus
