Android - How to access actionbar's menu items in fragment class - android

How should I access the actionbar's menu items in fragment ?
I have tried this but nothing happened
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// TODO Auto-generated method stub
switch (item.getItemId()) {
case R.id.menu_refresh:
Toast.makeText(getActivity().getApplicationContext(), "clicked", Toast.LENGTH_SHORT).show();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
// TODO Auto-generated method stub
super.onCreateOptionsMenu(menu, inflater);
}

Follow this steps:
Add setHasOptionsMenu(true) method in your Fragment.
Override onCreateOptionsMenu(Menu menu, MenuInflater inflater) and
onOptionsItemSelected(MenuItem item) methods in your Fragment.
Inside your onOptionsItemSelected(MenuItem item) Activity's method,
make sure you return false when the menu item action would be
implemented in onOptionsItemSelected(MenuItem item) Fragment's
method.
Example:
Activity
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.activity_menu_item:
// Do Activity menu item stuff here
return true;
case R.id.fragment_menu_item:
// Not implemented here
return false;
default:
break;
}
return false;
}
Fragment
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
....
}
#Override
public void onCreateOptionsMenu(Menu menu,MenuInflater inflater) {
// Do something that differs the Activity's menu here
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.activity_menu_item:
// Not implemented here
return false;
case R.id.fragment_menu_item:
// Do Fragment menu item stuff here
return true;
default:
break;
}
return false;
}

In your fragments onCreate method add setHasOptionsMenu(true);.
If your fragment is in a ViewPager then the fragment with the ViewPager also needs the above line.

You cant access directly ActionBar menu items in a Fragment.
What you can do is put setHasOptionsMenu(true); in onCreateView function in fragment class and this calls the function onCreateOptionsMenu(Menu menu) in the corresponding activity.
There, you can access all the menu items you have in the action bar.
You can use:
MenuItem item = menu.getItem(index);
You have one example of using this:
in fragment onCreateView class:
setHasOptionsMenu(true);
in corresponding activity class:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
MenuItem item = menu.getItem(0);
if(condition)
item.setVisible(true);
else
item.setVisible(false);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
if (mDrawerToggle.onOptionsItemSelected(item)) {
return true;
}
// Handle action bar actions click
switch (item.getItemId()) {
case R.id.action_logout:
makeLogout();
return true;
default :
return super.onOptionsItemSelected(item);
}
}

One thing I would add to this (my reputation does not allow me to comment) and reason it was not working for me.
Make sure your fragment's hosting activity extends AppCompatActivity not FragmentActivity!
public class MainActivity extends AppCompatActivity {
}
From the Google Reference Documentation for FragmentActivity:
Note: If you want to implement an activity that includes an action bar, you should instead use the ActionBarActivity class, which is a subclass of this one, so allows you to use Fragment APIs on API level 7 and higher.
ActionBarActivity now being deprecated, use AppCompatActivity instead. When using AppCompatActivity, also make sure you set "the activity theme to Theme.AppCompat or a similar theme" (Google Doc too).
android.support.v7.app.AppCompatActivity is a subclass of the android.support.v4.app.FragmentActivity class (see AppCompatActivity ref doc).

Menu item main.xml file :
<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="dbl.contact.manager.MainActivity" >
<item
android:id="#+id/menu_search"
android:actionLayout="#layout/action_bar"
android:icon="#drawable/searchagain"
android:orderInCategory="0"
android:showAsAction="always"
android:title="search"/>
</menu>
This is Menu item. custom action bar like edittext in the action bar You have to create a custom layout. Here custom action_bar.xml file :
<?xml version="1.0" encoding="utf-8"?>
<EditText
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/inputSearch"
android:layout_width="280dp"
android:layout_height="40dp"
android:cursorVisible="true"
android:hint="Search"
android:imeOptions="actionDone"
android:inputType="text"
android:textColor="#android:color/white"
android:textCursorDrawable="#android:color/white" />
Then in the fragment class you to override. Just Copy and paste this code.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
// TODO Add your menu entries here
super.onCreateOptionsMenu(menu, inflater);
getActivity().getMenuInflater().inflate(R.menu.main, menu);
View v = (View) menu.findItem(R.id.menu_search).getActionView();
inputSearch = (EditText)v.findViewById(R.id.inputSearch);
inputSearch.addTextChangedListener(new TextWatcher() {
#Override
public void afterTextChanged(Editable s) {
// TODO Auto-generated method stub
// clientAdapter.getFilter().filter(s.toString());
}
#Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
// TODO Auto-generated method stub
// ListData.this.clientAdapter.getFilter().filter(s);
}
#Override
public void onTextChanged(CharSequence s, int start, int before,
int count) {
// TODO Auto-generated method stub
adapter.getFilter().filter(s.toString());
}
});
}

onCreateOptionsMenu is never called (toolbar inflate)

My Fragment class:
Toolbar toolbar;
#Override
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
toolbar = getView().findViewById(R.id.toolbar3);
toolbar.inflateMenu(R.menu.menufragmentmain);
setHasOptionsMenu(true); //i also tried putting this function in oncreate function
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
Toast.makeText(getActivity(), "i never enter this function also" , Toast.LENGTH_LONG).show();
super.onCreateOptionsMenu(menu,inflater);
inflater.inflate(R.menu.menufragmentmain, menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
Toast.makeText(getActivity(), "i never enter this function" , Toast.LENGTH_LONG).show();
//some switch cases.....
return super.onOptionsItemSelected(item);
}
I've got a stupid error which I cant find unfourtantly. I've got a simple toolbar for my fragment. In onViewCreated I inflate my actionbar menu with my toolbar.
The issue is that the functions onCreateOptionsMenu and 'onOptionsItemSelected' are never called. I've got no clue why.
Things i checked in other similar questions with the same issue:
I checked if my main activity has a onCreateOptionsMenu or'onOptionsItemSelected'. It doesn*t
Checked if my style class has NOT: android:theme="#android:style/Theme.Black.NoTitleBar
None of the points unfourtantly work. What did I miss. Do I need to check something else?
As per the Fragment-owned app bar guide which explains how to use a Fragment-owned Toolbar, you do not use any of the setHasOptionsMenu(), onCreateOptionsMenu(), or onOptionsItemSelected() APIs - those are only used for activity owned app bars.
Instead, you would follow the guide for handling menu click events by using the Toolbar APIs:
public void onViewCreated(View view, #Nullable Bundle savedInstanceState) {
toolbar = getView().findViewById(R.id.toolbar3);
toolbar.inflateMenu(R.menu.menufragmentmain);
toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
Toast.makeText(getActivity(), "onMenuItemClick called" , Toast.LENGTH_LONG).show();
//some switch cases.....
return true;
}
});
}
Set up the toolbar in the host Activity. Then override the menu handling in each Fragment wherever necessary.
Here's some generic scaffolding (with comments):
public class MyFragment extends Fragment {
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Report that this Fragment has an options menu
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(#NonNull Menu menu, #NonNull MenuInflater inflater) {
// Inflate then menu, and THEN call super()
// Note the order of the invocations
inflater.inflate(R.menu.my_menu, menu);
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(#NonNull MenuItem item) {
// Handle menu item selections
final int itemId = item.getItemId();
switch(itemId) {
case R.id.my_menu_option_x: ...; return true;
case R.id.my_menu_option_y: ...; return true;
case R.id.my_menu_option_z: ...; return true;
default: return super.onOptionsItemSelected(item);
}
}
}

Unable to receive click on menu items in Fragment

I'm having a ToolBar made as ActionBar in a Fragment. I'm able to add ActionBar menu items but I'm not able to receive click response when I click on any ActionBar menu item.
I have read a lot of similar questions, I tried all but I'm still facing issue, so asked a question here.
The Fragment
public class DetailFragment extends Fragment {
#Override
public View onCreateView(#NonNull LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
setHasOptionsMenu(true);
return inflater.inflate(R.layout.project_detail, container, false);
}
#Override
public void onViewCreated(#NonNull View view, #Nullable Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
mToolBar = (Toolbar)view.findViewById(R.id.tb_toolbar);
((AppCompatActivity)getActivity()).setSupportActionBar(mToolBar);
mToolBar.setTitle(R.string.project_details);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.project_detail_menu, menu);
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.options:
// do something
break;
}
return true;
}
In my case in code above, onOptionsItemSelected is not even getting called.
Any pointers why ?
The Activity where I'm inflating this Fragment -
public class TestJust extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_test_just);
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.replace(R.id.container, new ProjectDetailFragment());
ft.commit();
}
}
project_detail_menu.xml -
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
>
<item
android:id="#+id/options"
android:title="options"
android:icon="#android:drawable/ic_menu_more"
app:showAsAction="always"/>
</menu>
Most probably your problem is that you're always returning true from the activity's onOptionsItemSelected method.
When you return true, you consume the click event inside the method in the activity, that's why the click event never reaches the onOptionsItemSelected method inside your fragment.
Try this
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
menu.clear()
inflater.inflate(R.menu.project_detail_menu, menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.options:
// do something
return true;
default:
return super.onOptionsItemSelected(item);
}
Solution:
You are calling setHasOptionsMenu(true); in onCreateView()
Please call that method in onCreate()
Like this:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
Calling this method in onCreate() ensures that the menu must participate in Fragment.
Then,
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.fragment_menu_items, menu);
}
Finally,
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.options:
// do something
break;
}
return super.onOptionsItemSelected(item);
It should work now.
initialize option in onCreateOptionMenu then check it. you only inflate menu, use without initialize option, first initialize then use it.
like: MenuItem item = menu.findItem(R.id.option);
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
MenuItem item = menu.findItem(R.id.option);
}
switch (item.getItemId()) {
case R.id.options:
// do something
return true;//<- Here you need to return true because breaking compile from this line returns default false;
default:
return super.onOptionsItemSelected(item);
}

how to use Buttons on action bar With Fragments?

i want to add button on the actionbar of a fragment.But i'm getting error on this code given below.
this is my Fragment code where i want to add button on actionbar of this tab
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
final View view = inflater.inflate(R.layout.credit_main, container, false);
return view;
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu items for use in the action bar
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.search_menu, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
// action with ID action_refresh was selected
case R.id.search:
Toast.makeText(getActivity(), "Refresh selected", Toast.LENGTH_SHORT)
.show();
break;
default:
break;
}
return super.onOptionsItemSelected(item);
}
}
here error is getMenuInflater(); cannot resolve
Step 1 : Make a xml of menu which you want to add.
<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" >
<item
android:id="#+id/item1"
android:title="#string/filter"
android:orderInCategory="10"
android:icon="#drawable/ic_launcher"
app:showAsAction="ifRoom" />
</menu>
Step 2:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
Step 3:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.search_result, menu);
}
Step 4:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if(id == R.id.item1){
//What you want(Code Here)
return true;
}
return super.onOptionsItemSelected(item);
}
You have to call setHasOptionsMenu(true) to make it work.
Do something like:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
and then use the onCreateOptionsMenu() method with the inflater.
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
// Inflate the menu items for use in the action bar
inflater.inflate(R.menu.search_menu, menu);
super.onCreateOptionsMenu(menu, inflater);
}
Take a look at setHasOptionsMenu() and onCreateOptionsMenu().

Android: Fragment's onOptionsItemSelected doesn't get called

I have an ActionBarActivity and one Fragment. The Activity has no menu inflated, while the Fragment has a menu with two buttons. Fragment menu is visible, but the buttons don't react at all when tapped. At debugging I can see that both onCreateOptionsMenu() for Fragment and Activity get called, but when tapping buttons no onOptionsItemSelected() gets called, neither from Activity nor from Fragment.
Activity
#Override
public boolean onCreateOptionsMenu(Menu menu) {
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
return false;
}
Fragment
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mainActivity = (NavigationActivity)getActivity();
setHasOptionsMenu(true);
}
#Override
public View onCreateView(final LayoutInflater inflater, final ViewGroup container, final Bundle savedInstanceState){
return (ScrollView) inflater.inflate(R.layout.tutoring_detail, container, false);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.query_details_menu, menu);
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.accept_query:
respondToQuery(true);
return true;
case R.id.decline_query:
respondToQuery(false);
return true;
default:
break;
}
return false;
}
Menu to be displayed in Fragment
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
<item
android:id="#+id/accept_query"
android:orderInCategory="100"
app:showAsAction="always"
android:checkable="true"
style="?android:attr/borderlessButtonStyle"
app:actionViewClass="android.widget.ImageButton"/>
<item
android:id="#+id/decline_query"
android:orderInCategory="101"
app:showAsAction="always"
android:checkable="true"
style="?android:attr/borderlessButtonStyle"
app:actionViewClass="android.widget.ImageButton"/>
</menu>
In the Activity class,
#Override
public boolean onOptionsItemSelected(MenuItem item) {
super.onOptionsItemSelected(item);
return false;
}
In the Fragment,
#Override
public void onCreate(#Nullable Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
Toast.makeText(getActivity(), "called " + item.getItemId(), Toast.LENGTH_SHORT).show();
return super.onOptionsItemSelected(item);
}
You must use super.onOptionsItemSelected(item) in the parent activity's onOptionsItemSelected(...) method.
From Activity | Android Developers:
Derived classes should call through to the base class for it to perform the default menu handling.
Try moving setHasOptionsMenu(true) inside of the onCreateView() method in your Fragment instead of onCreate().
I had a similar issue after making special layout for my action button (I made an Image Button and needed to pad it and change some other things so I had to use layout for it).
Then onOptionsItemSelected lost connection with this imageButton so I just use clickListener for it inside onCreateOptionsMenu. It might not be the best practice, maybe there is a better solution, but this is what solve my problem.
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.picker_list_menu, menu);
MenuItem itemDone = menu.findItem(R.id.menu_done);
MenuItemCompat.setActionView(itemDone, R.layout.menu_layout_done);
menuDoneIB = (ImageButton) MenuItemCompat.getActionView(itemDone);
itemDone.getActionView().setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
//your code..
}
});
}
Try using oncreateview
public static class ExampleFragment extends Fragment {
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.example_fragment, container, false);
}
}
If you have dynamically changed menu item, for instance, a badge menu (https://stackoverflow.com/a/16648170/2914140 or https://stackoverflow.com/a/26017587/2914140), you should initialize the item in onCreateOptionsMenu and re-set setOnClickListeners after every change of the item.
In my case:
private MenuItem menuItem;
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_catalog, menu);
menuItem = menu.findItem(R.id.action_badge);
writeBadge(0);
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_badge) {
// Your code.
return true;
}
return super.onOptionsItemSelected(item);
}
private void writeBadge(int count) {
MenuItemCompat.setActionView(menuItem, R.layout.item_badge);
RelativeLayout layout = (RelativeLayout) MenuItemCompat.getActionView(menuItem);
// A TextView with number.
TextView tv = (TextView) layout.findViewById(R.id.badge);
if (count == 0) {
tv.setVisibility(View.INVISIBLE);
} else {
tv.setVisibility(View.VISIBLE);
tv.setText(String.valueOf(count));
}
// An icon, it also must be clicked.
ImageView imageView = (ImageView) layout.findViewById(R.id.image);
View.OnClickListener onClickListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
onOptionsItemSelected(menuItem);
}
};
menuItem.getActionView().setOnClickListener(onClickListener);
imageView.setOnClickListener(onClickListener);
}
I am passing the click event to fragment from the activity. This worked for me.
#Override
public boolean onOptionsItemSelected(#NonNull MenuItem item) {
return getSupportFragmentManager().getFragments().get(getSupportFragmentManager().getFragments().size() - 1)
.onOptionsItemSelected(item);
}

(Deprecated) Fragment onOptionsItemSelected not being called

EDIT:
This question was for the deprecated sherlock action bar. Android support library should be used instead now
I have added an action bar menu option called share for my fragment which appears but the selection event is not being caught
I am adding it like this
#Override
public void onCreateOptionsMenu (Menu menu, MenuInflater inflater) {
MenuItem item = menu.add(0, 7,0, R.string.share);
item.setIcon(R.drawable.social_share).setShowAsAction(MenuItem.SHOW_AS_ACTION_IF_ROOM);
}
Trying to capture it in both the fragment and the fragment activity like
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case 7:
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("text/plain");
share.putExtra(Intent.EXTRA_TEXT, "I'm being sent!!");
startActivity(Intent.createChooser(share, "Share Text"));
return true;
default:
return super.onOptionsItemSelected(item);
}
}
and I have setHasOptionsMenu(true); in the onCreate().
Same problems happened to me:
onMenuItemSelected events didn't get called in Fragment
Searched google cann't find a solution, and add onMenuItemSelected method in FragmentActivity doesn't solve it.
Finally resolve it by following reference to http://developer.android.com/guide/topics/ui/actionbar.html
Note: If you added the menu item from a fragment, via the Fragment class's onCreateOptionsMenu callback, then the system calls the respective onOptionsItemSelected() method for that fragment when the user selects one of the fragment's items. However the activity gets a chance to handle the event first, so the system calls onOptionsItemSelected() on the activity before calling the same callback for the fragment.
Which means only if you don't have that menu item handler in onOptionsItemSelected() on the activity, the onOptionsItemSelected() on the fragment will be called.
Code as following
-----Remove the handler for R.action.add on FragmentActivity):
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case android.R.id.home:
popBackStack();
return true;
case R.id.action_search:
searchAction();
return true;
case R.id.action_logout:
userLogout();
return true;
//case R.id.action_add:
//return true;
default:
return super.onOptionsItemSelected(item);
}
}
And the handler for R.action.add on Fragment looks like this:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
Log.d("onOptionsItemSelected","yes");
switch (item.getItemId()) {
case R.id.action_add:
add();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
Finally, remember to add
setHasOptionsMenu(true);
in your onCreate method in Fragment
I had the same problem, but I think it's better to summarize and introduce the last step to get it working:
Add setHasOptionsMenu(true) method in your Fragment's onCreate(Bundle savedInstanceState) method.
Override onCreateOptionsMenu(Menu menu, MenuInflater inflater) (if you want to do something different in your Fragment's menu) and onOptionsItemSelected(MenuItem item) methods in your Fragment.
Inside your Activity's onOptionsItemSelected(MenuItem item) method, make sure you return false when the menu item action would be implemented in Fragment's onOptionsItemSelected(MenuItem item) method.
An example:
Activity
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.activity_menu_item:
// Do Activity menu item stuff here
return true;
case R.id.fragment_menu_item:
// Not implemented here
return false;
default:
break;
}
return false;
}
Fragment
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
....
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
// Do something that differs the Activity's menu here
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.activity_menu_item:
// Not implemented here
return false;
case R.id.fragment_menu_item:
// Do Fragment menu item stuff here
return true;
default:
break;
}
return false;
}
I have noticed that the solution people gave you was to implement the code for your menue item in the activity rather then the fragment.
I think it will look much more orgenized if you had implemented the code in the fragment rather then the activity 'cos in my opinion it looks better.
To do so, do as follows :
Activity
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.SomeIDInTheMenueOfTheActivity:
{
//something();
break;
}
default:
//do something default and add the code under :
return super.onOptionsItemSelected(item);
}
return true;
}
Fragment
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item)
{
switch (item.getItemId())
{
case R.id.SomeIDInFragmentMenue:
{
break;
}
default:
return super.onOptionsItemSelected(item);
}
return true;
}
Now the lines (and the likes): "return super.onOptionsItemSelected(item);" in the activity and fragment are super important, because as if you will follow the code in debug, you will see that the menue events functions will be called first on the Activity, and if the item did not match the id's in the activity's switch-case, the degault line : "super.onOptionsItemSelected(item);" will call the onOptionsItemSelected function on the fragment, as we wanted.
(if you have many fragments, make sure to have that line in them as well, as the calling hirarchy can be somewhat complicated).
I'm using actionbarsherlock. This worked for me:
1) Create dummy_menu.xml menu
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="match_parent" android:layout_width="fill_parent" >
<item
android:title=""
android:showAsAction="never"
android:id="#+id/dummyMenu"
/>
2) In activity inflate the menu like this:
#Override
public boolean onCreateOptionsMenu(com.actionbarsherlock.view.Menu menu) {
com.actionbarsherlock.view.MenuInflater inflater = getSupportMenuInflater();
inflater.inflate(R.menu.dummy_menu,menu);
return super.onCreateOptionsMenu(menu);
}
3) In fragments onCreateView call setHasOptionsMenu(true) and override onCreateOptionsMenu and onOptionsItemSelected also hide the dummyMenu like this (in fragment)
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.fragment_actions, menu);
MenuItem item = menu.findItem(R.id.dummyMenu);
item.setVisible(false);
super.onCreateOptionsMenu(menu, inflater);
}
Hope it helps someone.
Edit for actionbar sherlock use
I had to use
public boolean onMenuItemSelected(int featureId, MenuItem item) {
in the main activity to capture the menu item
it's so simple you can do that in your fragment to make sure that your action will listen correctly:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
From the documentation, it should solve by this steps:
If you in Activity Using the addMenuProvider() API directly:
class ExampleActivity : ComponentActivity(R.layout.activity_example) {
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
// Add menu items without overriding methods in the Activity
addMenuProvider(object : MenuProvider {
override fun onCreateMenu(menu: Menu, menuInflater: MenuInflater) {
// Add menu items here
menuInflater.inflate(R.menu.example_menu, menu)
}
override fun onMenuItemSelected(menuItem: MenuItem): Boolean {
// Handle the menu selection
return true
}
})
}
}
If you in Fragment Using the addMenuProvider() API
class ExampleFragment : Fragment(R.layout.fragment_example) {
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
// The usage of an interface lets you inject your own implementation
val menuHost: MenuHost = requireActivity()
// Add menu items without using the Fragment Menu APIs
// Note how we can tie the MenuProvider to the viewLifecycleOwner
// and an optional Lifecycle.State (here, RESUMED) to indicate when
// the menu should be visible
menuHost.addMenuProvider(object : MenuProvider {
override fun onCreateMenu(menu: Menu, menuInflater: MenuInflater) {
// Add menu items here
menuInflater.inflate(R.menu.example_menu, menu)
}
override fun onMenuItemSelected(menuItem: MenuItem): Boolean {
// Handle the menu selection
return true
}
}, viewLifecycleOwner, Lifecycle.State.RESUMED)
}
I had this problem. It was because I was overiding the wrong method
onOptionsItemSelected(com.actionbarsherlock.view.MenuItem item)
is what I used.
Make sure you are using the right one!
You are not chaining to the superclass in the activity methods. Please have onCreateOptionsMenu() return super.onCreateOptionsMenu(menu), and have onOptionsItemSelected() return super.onOptionsItemSelected(item) (except for the item that you are handling, which should return true to indicate that you have handled the event)
you must add this code toolbar.bringToFront(); next set toolbar in your activity
public class MainActivity extends AppCompatActivity {
protected void onCreate(Bundle savedInstanceState) {
...
Toolbar toolbar = findViewById(R.id.toolbar);
toolbar.setTitle("Yazd");
setSupportActionBar(toolbar);
toolbar.bringToFront(); // <<= add here
...
