Develop Reference

Option in Option menu are not visible instead it is showing only white blank space,here are my menu xml and main activity

the button more information is not visible!!!!
xml of menu :-
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/more_information"
android:title="#string/action_mnn"
/>
</menu>
main activity :-
package com.example.yashchaudhary.modernartui;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu){
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_menu, menu);
return true;
}
public boolean onOptionsItemSelected(MenuItem item){
switch (item.getItemId()){
case R.id.more_information:
return true;
default :
return super.onOptionsItemSelected(item);
}
}
}
screenshot after clickin on 3 dots

In my case it was a Theme specific for the action bar in the activity layout
<androidx.appcompat.widget.Toolbar
android:id="#+id/toolbar"
android:theme="#style/ThemeOverlay.MaterialComponents.Dark.ActionBar"
.../>
Removing the theme property solved my problem

<androidx.appcompat.widget.Toolbar android:id="#+id/toolbar" android:theme="#style/ThemeOverlay.MaterialComponents.Dark.ActionBar"/>
Removing the theme attribute will resolve this problem.

Try to add to the item on the menu xml
android:orderInCategory="100"
and add break; after
case R.id.more_information:
return true;

menu not appearing in Fragment

I'm attempting to put a menu into a fragment in my app. However, the menu isn't appearing when I run it. My understanding of the steps involved in making a menu display in a fragment (and please correct me if I'm wrong or missing something) is that you do the following:
Create a menu resource file in the res/menu directory.
Override onCreateOptionsMenu(Menu, MenuInflater) and within said method, inflate the layout defined by the menu resource ID.
Notify the fragment manager that this fragment should receive a call to onCreateOptionsMenu by calling setHasOptionsMenu(true) in the fragment's onCreate method.
I've written a reduced version of my code to only include the bare minimum of what (I believe) should show a menu. Can anyone tell me what's missing from this code?
Here is my menu resource xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/menu_item_1"
android:icon="#android:drawable/ic_menu_add"
android:title="#string/menu_item_text"
android:showAsAction="ifRoom|withText"/>
</menu>
My fragment code:
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.View;
import android.view.ViewGroup;
public class MainFragment extends Fragment {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setHasOptionsMenu(true);
}
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.fragment_menu, menu);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup parent, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_main, parent, false);
return v;
}
}
And my activity code:
package com.bignerdranch.android.fragmentmenuexample;
import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentActivity;
import android.support.v4.app.FragmentManager;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
public class MainActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
FragmentManager fm = getSupportFragmentManager();
Fragment fragment = fm.findFragmentById(R.id.fragmentContainer);
if (fragment == null) {
fragment = new MainFragment();
fm.beginTransaction()
.add(R.id.fragmentContainer, fragment)
.commit();
}
}
}
And my manifest:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.bignerdranch.android.fragmentmenuexample" >
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
I'm running this on an AVD Galaxy Nexus running IceCreamSandwich.

Problem solved. My styles.xml file had the following:
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
I added a new resource directory values-v14 and added the following style to it:
<style name="AppTheme" parent="android:Theme.Holo.Light.DarkActionBar">

I think you missed to override onCreateOptionsMenu in your MainActivity.
If you don't need to inflate any menu, simply return true :
#Override
public boolean onCreateOptionsMenu ( Menu menu ) {
return true;
}

U can simpley create a Android Sample Project, as guide you can choose with menu or othey style, you can find what different with your code.

You could override the following function in your 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;
}
This will solve the problem.

you can get individual menu items to show in the ActionBar by adding the android:showAsAction="always" attribute

Menu item not working

I am doing menu item. But i am not able to view the menu item in the screen. Can anybody tell me what is getting wrong or what other need to be added to get the code working. I have got totally stuck.
package com.example.androiddemo;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuInflater;
public class MenuItem extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.menu.menupage);
}
public boolean onCreateOptionsMenu(Menu menu){
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menupage, menu);
return true;
}
}
xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/about"
android:icon="#drawable/images"
android:title="About"
android:showAsAction="ifRoom"
/>
<item
android:id="#+id/setting"
android:icon="#drawable/ic_launcher"
android:title="App Setting"
/>
</menu>

Here you have to set your activity's xml file.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main); // Your activity's xml file.
}
public boolean onCreateOptionsMenu(Menu menu){
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menupage, menu); // Here you are setting the menu whatever options you want.
return true;
}
}
After running this, just press on menu, It should show your options. If not post back.
