MenuInflater not working - menu not showing

My menu is not showing in the ActionBar (onCreateOptionsMenu) is called properly. The icon and string are available. The code works fine in my other projects. I am using android.support.v7.app.ActionBarActivity for android:
<uses-sdk
android:minSdkVersion="11"
android:targetSdkVersion="21" />
Code:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu items for use in the action bar
Log.i("onCreate", "menu");
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.add, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.action_add:
Intent addIntent = new Intent(this, RoomAddActivity.class);
startActivity(addIntent);
break;
}
return super.onOptionsItemSelected(item);
}
XML:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/action_add"
android:icon="#drawable/ic_action_new"
android:showAsAction="always"
android:title="#string/action_add"/>
</menu>

Try to return true explicitly:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu items for use in the action bar
Log.i("onCreate", "menu");
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.add, menu);
super.onCreateOptionsMenu(menu);
return true;
}
Updated:
By the way, you are not obliged to call super method. As to my experience it works all right without it.

Menu setActionView(view) to xml

In onCreateOptionsMenu I'm setting an action view with:
MenuItem item = ..
item.setActionView(action_view)
item.setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
and it works ok. But I want to move this to my xml menu and I can't seem to make it show. It only shows up the title. I tried many versions, like:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourApp="http://schemas.android.com/apk/lib/myPackage.myClass" >
<item
android:id="#+id/item"
yourApp:actionViewClass="action_view"
android:showAsAction="always" or youtApp:showAsAction="always"
android:title="title"
</item>
The problem must be it getting to the action_view variable, but I can't seem to figure it out

Did you inflate the menubar?
#Override
public void onCreateOptionsMenu (Menu menu, MenuInflater inflater) {
inflater.inflate(R.menu.menu_name, menu);
mMenu = menu;
if(mMenu != null){
MenuItem item = mMenu.findItem(R.id.item_id);
if(item != null){
item.setVisible(false);
}
}
super.onCreateOptionsMenu(menu, inflater);
}
Also do you have setHasOptionsMenu(true); #onCreate() function?

Try this:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.item:
// Write your action_view here
break;
case R.id.your_other_item_id:
//Your other Menu item logic
break;
}
return super.onOptionsItemSelected(item);
}

OptionsMenu not working

I have this fragment connected with a menu.xml. I the menu opens when i click it, everything works besides the onOptionsItemSelected. I've tried to log it but nothing gives result. Why isn't my code working?
Activity
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
// TODO Add your menu entries here
super.onCreateOptionsMenu(menu, inflater);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId())
{
case R.id.clear:
writetofile("0", "file1.txt");
writetofile("0", "file2.txt");
writetofile("0", "file3.txt");
break;
case R.id.add:
writetofile("1", "file1.txt");
writetofile("1", "file2.txt");
writetofile("1", "file3.txt");
break;
}
return true;
}
XML
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/clear"
android:orderInCategory="100"
android:title="Clean"/>
<item
android:id="#+id/add"
android:orderInCategory="100"
android:title="Add"/>

You didn't inflate the menu
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.menu, menu);
}

Menu.xml programmatically

i have menu.xml like this:
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/settings"
android:alphabeticShortcut="#string/settings_shortcut"
android:icon="#drawable/setting"
android:title="#string/settings"/>
<item
android:id="#+id/info"
android:alphabeticShortcut="#string/info_shortcut"
android:icon="#drawable/info"
android:title="#string/info"/>
</menu>
Now we usually do it like this:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
return true;
}
But how can i do this programatically ? without using xml

you can use Menu.add
For example, to create a "New" menu with an id
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.add(0, id, 0, "New");
return true;
}

Menu not showing up

I have added a simple menu but its not showing up.
this is menu.xml file-
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#+id/settings"
android:alphabeticShortcut="#string/settings_shortcut"
android:title="#string/settings_label"></item>
</menu>
this is main.java file-
#Overridek
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
return true;
}
I just wanted to keep it simple.

Inflate your menu options in your .java file through this -
// Initiating Menu XML file (menu.xml)
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.layout.menu, menu);
return true;
}
Hope this helps you lot.

You should delete this line : super.onCreateOptionsMenu(menu);
#Override
public boolean onCreateOptionsMenu(Menu menu) {
//super.onCreateOptionsMenu(menu);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
return true;
}
