Menu items are not showing on my android phone

I am running this code on my android phone and i am unable to see menu items on my android phone but when i run this on emulator, i can see menu items.
Please help . Here is the screenShot of.
<item android:title="About Us"
android:id="#+id/aboutUs_ID"/>
<item android:title="Preferences"
android:id="#+id/preferences_ID"/>
java code in activity
#Override
public boolean onCreateOptionsMenu(android.view.Menu menu) {
super.onCreateOptionsMenu(menu);
MenuInflater myMenu = getMenuInflater();
myMenu.inflate(R.menu.menu_file, menu);
return true;
}

Try to use below solution;
res/menu/main.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/action_settings"
android:orderInCategory="100"
android:title="Color Theam"
app:showAsAction="never" />
<item
android:id="#+id/action_appMahiti"
android:orderInCategory="100"
android:title="#string/tab_refrence"
app:showAsAction="never" />
</menu>
Here is the code snippiest you can add in your activity class
Activity.java
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu;
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
switch (id) {
case R.id.action_settings:
// perform operation or display message
Toast.makeText(this, "CLick me", Toast.LENGTH_SHORT).show();
break;
case R.id.action_appMahiti:
// perform operation
startActivity(new Intent(this, XYZ.class));
break;
}
return super.onOptionsItemSelected(item);
}
I will suggest to try to use above solution.

Implementing an option menu in Android Studio

How do I implement an option menu in my android application? I tried code from Android Developer but I get errors. Such as these: Element menu must be declared. Here is my code
<?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"
android:showAsAction="ifRoom"/>
<item android:id="#+id/help"
android:icon="#drawable/ic_help"
android:title="#string/help" />
</menu>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.lucavanraalte.test" >
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:supportsRtl="true"
android:theme="#style/AppTheme" >
<activity android:name=".MainActivity" android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>

In your java code, add this onCreateOptionsMenu to show optionMenu,
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.option_menu, menu); //your file name
return super.onCreateOptionsMenu(menu);
}
Keep your under res\menu\option_menu folder,
<?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"
android:showAsAction="ifRoom"/>
<item android:id="#+id/help"
android:icon="#drawable/ic_help"
android:title="#string/help" />
</menu>
Now, if you want to set onOptionsItemSelected i.e onClick event for that ou can use,
#Override
public boolean onOptionsItemSelected(final MenuItem item) {
switch (item.getItemId()) {
case android.R.id.new_game:
//your code
// EX : call intent if you want to swich to other activity
return true;
case R.id.help:
//your code
return true;
default:
return super.onOptionsItemSelected(item);
}
}

You should use onCreateOptionsMenu (Menu menu)
Initialize the contents of the Activity's standard options menu. You
should place your menu items in to menu.
This is only called once, the first time the options menu is
displayed. To update the menu every time it is displayed, see
onPrepareOptionsMenu(Menu).
onCreateOptionsMenu(Menu menu) method which needs to override in Activity class. This creates menu and returns Boolean value. inflate inflates a menu hierarchy from XML resource.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.option_menu, menu); // set your file name
return super.onCreateOptionsMenu(menu);
}
Your option_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/item_First"
android:title="#string/item_First"
android:showAsAction="ifRoom"/>
<item android:id="#+id/save_menu"
android:title="#string/save"
android:showAsAction="ifRoom"/>
<item android:id="#+id/item_Second"
android:title="#string/item_First"
android:showAsAction="ifRoom"/>
</menu>
Please check demo Android Option Menu Example

You need to create a menu folder in the res directory and in the menu directory create file named my_menu.xml. In that file write these lines:
<?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"
android:showAsAction="ifRoom"/>
<item android:id="#+id/help"
android:icon="#drawable/ic_help"
android:title="#string/help" />
</menu>
Then in your Activity, do this:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.my_menu, menu);
return true;
}

You need to create a menu.xml in directory res->menu like menu
<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"
android:showAsAction="ifRoom"/>
<item android:id="#+id/help"
android:icon="#drawable/ic_help"
android:title="#string/help" />
</menu>
Then you need to create your menu from activity with below code
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.help) {
//do something
return true;
}
if (id == R.id.new_game) {
//do something
return true;
}
return super.onOptionsItemSelected(item);
}

#Override
public boolean onCreateOptionsMenu(Menu menu) {
menu.add("Home");
menu.add("Profile");
menu.add("Settings");
menu.add("Privacy Policy");
menu.add("Terms of use");
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(#NonNull MenuItem item) {
if (item.getTitle()=="Home"){
Toast.makeText(this, "Home option selected", Toast.LENGTH_SHORT).show();
}else if (item.getTitle()=="Profile"){
Toast.makeText(this, "Profile option selected", Toast.LENGTH_SHORT).show();
}else if (item.getTitle()=="Settings"){
Toast.makeText(this, "Settings option selected", Toast.LENGTH_SHORT).show();
}else if (item.getTitle()=="Privacy Policy"){
Toast.makeText(this, "Privacy Policy option selected", Toast.LENGTH_SHORT).show();
}else if (item.getTitle()=="Terms of use"){
Toast.makeText(this, "Terms of use option selected", Toast.LENGTH_SHORT).show();
}
return super.onOptionsItemSelected(item);
}

How to edit the list in the right up corner that contains settings?

I tried
#Override
public boolean onCreateOptionsMenu(Menu menu) {
Log.v(
this.getClass().getName() + "!!!",
new Exception().getStackTrace()[0].getMethodName()
);
MenuItem m_item = (MenuItem)menu.findItem(R.id.action_settings);
if(m_item != null)
m_item.setTitle("Back to test");
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.settings, menu);
return true;
}
but it always gets null.And also,onCreate seems to have it as null as well. Is there a function that i can modify the text on it during runtime??? And if so, is there an easy way to find it?

You should add items in the menu xml. You can find it on the folder res/menu. There you have all the menus available for inflation.
I suppose that you have only one. This is how it could look with added options:
<?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/searchMain"
android:icon="#drawable/ic_action_search"
app:showAsAction="ifRoom|withText"
android:title="Search"/>
<item
android:id="#+id/searchBarcodeScan"
android:icon="#drawable/ic_launcher"
app:showAsAction="always|withText"
android:title="Scanner"/>
<item
android:id="#+id/seeList"
android:icon="#drawable/ic_launcher"
app:showAsAction="ifRoom|withText"
android:title="See list"/>
<item
android:id="#+id/settings"
android:icon="#drawable/ic_settings"
app:showAsAction="ifRoom|withText"
android:title="Settings"/>
</menu>
Then in your activity you can react to the option selected by overriding this method and doing things inside it:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.searchMain:
doSomething();
return true;
case R.id.searchBarcodeScan:
doSomething2();
return true;
case R.id.seeList:
doSomething3();
return true;
case R.id.settings:
doSomething4();
return true;
}
return super.onOptionsItemSelected(item);
}
EDIT
In order to change menus in runtime, you should call the method invalidateOptionsMenu(). This method will force the recreation of the menu and this time onPrepareOptionsMenu method will be called. You should override it in your Activity this way:
#Override
public boolean onPrepareOptionsMenu(Menu menu) {
if(someCondition){
getMenuInflater().inflate(R.menu.main_menu, menu);
}
else if(someOtherCondition){
getMenuInflater().inflate(R.menu.other_menu, menu);
}
return true;
}

Instead of
getMenuInflater().inflate(R.menu.settings, menu);
do something like:
getMenuInflater().inflate(R.menu.menu_custom, menu);
where res/menu/menu_custom.xml is something like:
<?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/menu_search"
android:icon="#drawable/ic_action_search"
android:title="#string/search"/>
<item android:id="#+id/menu_settings"
android:icon="#drawable/ic_action_settings"
android:title="#string/settings" />
</menu>
This will give you two items in the dropdown. It looks like your res/menu/settings.xml only has one item in it.

Adding a button to the Action Bar in Android?

For some reason, I cannot get my button to appear on the Action Bar. I have defined it in an XML file in /res/menu, along with inflating it and listening for an action. The icon is present in /res/drawable-hdpi. And nothing of interest shows in logcat. :(
XML:
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:id="#+id/logout"
android:icon="#drawable/logout"
android:title="Logout"
android:orderInCategory="100"
android:showAsAction="always" />
</menu>
Code in main activity:
public class MainActivity extends ActionBarActivity {
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_activity_actions, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle presses on the action bar items
switch (item.getItemId()) {
case R.id.logout:
//logout code
return true;
default:
return super.onOptionsItemSelected(item);
}
}
//rest of app
}
I followed this question for my initial problem, and it didn't help. How to add button in ActionBar(Android)?

Try with this change:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
<item android:id="#+id/logout"
android:icon="#drawable/logout"
android:title="Logout"
android:orderInCategory="100"
yourapp:showAsAction="always" />
</menu>

Android SubMenus not doing anything when clicked

I feel this may be a stupid question but I have no idea what to do.
I have a menu which works correctly. One of the items in the menu: "Search" brings up a submenu with different items like "Restaurant", "Cafe", etc.
Below is the XML code for creating the menu and sub menu:
<?xml version="1.0" encoding="utf-8"?>
<menu
xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/new_entry"
android:title="#string/new_entry"
android:icon="#drawable/add_new">
</item>
<item android:id="#+id/search"
android:title="#string/search"
android:icon="#drawable/search">
<menu>
<item android:id="#+id/five"
android:title="#string/five">
</item>
<item android:id="#+id/ten"
android:title="#string/ten">
</item>
<item android:id="#+id/fifteen"
android:title="#string/fifteen">
</item>
<item android:id="#+id/restaurant"
android:title="#string/restaurant">
</item>
<item android:id="#+id/cafe"
android:title="#string/cafe">
</item>
<item android:id="#+id/sandwich"
android:title="#string/sandwich">
</item>
</menu>
</item>
<item android:id="#+id/info"
android:title="#string/info_short"
android:icon="#drawable/info">
</item>
Then in my Activity Class I have:
// Initialise Menu.
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_services, menu);
return true;
}
and:
// Create cases for each menu selection.
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.new_entry:
createFood();
return true;
case R.id.search:
return true;
case R.id.cafe:
Log.d(TAG, "In Cafe SubMenu");
Toast.makeText(getApplicationContext(), TAG, Toast.LENGTH_SHORT);
return true;
case R.id.info:
info();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
Each case in "onOptionsItemSelected" does what it is supposed to do, except "case R.id.cafe:" which is the submenu. Here it should post to the LogCat and a Toast for testing but does neither.
What am I missing?
Thanks

I have tried your code and it is working perfectly. Only the Toast is not displaying when I select 'cafe'. That is because, you did not call show() in your code. Your code is
Toast.makeText(getApplicationContext(), TAG, Toast.LENGTH_SHORT);
to show the toast on run time it should call as follows
Toast.makeText(getApplicationContext(), TAG, Toast.LENGTH_SHORT).show();
:)

I think you should remove following lines:
case R.id.search:
return true;
