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);
}

I can't add buttons in Actionbar

I want to add buttons in Actionbar of Android Support library.
Actionbar is shown, but no button appears.
Below is res/menu/main.xml
menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:showAsAction="always"
android:icon="#android:drawable/ic_menu_preferences"
android:title="#string/action_settings"/>
</menu>
and I add following code.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
MenuInflater inflater=getMenuInflater();
inflater.inflate(R.menu.main, menu);
return true;
}
What should I do??

try this:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(menu);
}

Inside a Fragment:
#Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
{
inflater.inflate(R.menu.main, menu);
super.onCreateOptionsMenu(menu, inflater);
}
Also, remember to set setHasOptionsMenu(true); in your onActivityCreated method.
In an Activity:
#Override
public boolean onCreateOptionsMenu(Menu menu)
{
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
return super.onCreateOptionsMenu(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;
}

I tried running this code , no output on emulator nor any error. Cant make the menu pop up what to do?

package com.guess.phone;
import android.app.Activity;
public class Menu extends Activity {
// Setting Up the MenuInflater
public boolean onCreateOptionsMenu(Menu Menu) {
super.onCreateOptionsMenu((android.view.Menu) Menu);
MenuInflater awesome = getMenuInflater();
awesome.inflate(R.menu.main_menu,(android.view.Menu) Menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()) {
case R.id.menuSweet:
startActivity(new Intent("com.guess.phone.SWEET"));
return true;
case R.id.menuToast:
return true;
}
return false;
}
}

Use below OnCreateOptionsMenu instead
public boolean OnCreateOptionsMenu(Menu menu){
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return super.onCreateOptionsMenu(menu);
}
