Where to add menu to work in all activities

I have a menu.xml and the code to show the menu in action bar. Do i have to add the code in every activity? Cause after this i use a switch case to get click, and more code, so i dont thing its the wright way to copy-paste the same code in every activity
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
Is there a better way to do it as to work in all app (all activities)?

Create a BaseActivity class.
public class BaseActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_main, menu);
return true;
}
}
Now all activities that extend your base activity will have the same menu.

this is a guide for Android Menu
this is an example menu:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/new_game"
android:icon="#drawable/ic_new_game"
android:title="#string/new_game" />
<item android:id="#+id/help"
android:icon="#drawable/ic_help"
android:title="#string/help" />
</menu>
And then inflating it within your activity:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.game_menu, menu);
return true;
}
whe item clicked:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.new_game:
newGame();
return true;
case R.id.help:
showHelp();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
good luck and read the doc official for android

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.

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 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;
}

android menu items do not display

there is an activity in my android application. I override the 'onCreateOptionsMenu' method, adding four menu items in the activity. But the menu items do not display. I can not figure out what is the problem. Could somebody give me an clue to fix that or explaination?
#Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
menu.add(0, FeaturedActivity.MENU_FEATURED, 0, R.string.menu_featured).setIcon(R.drawable.icon_tabbar_featured);
menu.add(0, FeaturedActivity.MENU_THE_DRINK, 1, R.string.menu_the_drink).setIcon(R.drawable.icon_tabbar_drinks);
menu.add(0, FeaturedActivity.MENU_PLAYER, 2, R.string.menu_player).setIcon(R.drawable.icon_tabbar_player);
menu.add(0, FeaturedActivity.MENU_SHARE, 3, R.string.menu_share).setIcon(R.drawable.icon_tabbar_share);
return true;
}

in your activity use
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.optionsmenu, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.info:
startActivity(new Intent(this, AboutApp.class));
return true;
case R.id.exit:
finish();
return true;
}
return false;
}
and create a folder menu in res and now create an xml in res/menu like optionsmenu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/info" android:title="Info"
android:icon="#drawable/info_menubtn" />
<item android:id="#+id/exit" android:title="Exit" />
</menu>
Hope this will work for you

remove the line super.onCreateOptionsMenu(menu); and try .

#Override
public boolean onCreateOptionsMenu(Menu menu) {
// TODO Auto-generated method stub
menu.add("this is menu");
menu.add("this is another");
return super.onCreateOptionsMenu(menu);
}
edit into above code and add return super.onCreateOptionsMenu(menu); at last and remove it from first line
