I follow the tutorial https://www.youtube.com/watch?v=iEXh1-KVeVc&t=213s for making bottom menu.
Then i use onCreateOptionsMenu and onOptionsItemSelected to set action when click in, but it still not working.
Here is my menu code:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/leftNav"
android:icon="#drawable/ic_baseline_stars_24"
android:title="News"/>
<item
android:id="#+id/home"
android:title=""/>
<item
android:id="#+id/rightNav"
android:icon="#drawable/ic_baseline_menu_24"
android:title="Menu"/>
</menu>
MainActivity.java code:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate menu
getMenuInflater().inflate(R.menu.bottom_nav_menu, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.leftNav:
// Left nav
Toast.makeText(this,"Click left",Toast.LENGTH_LONG);
return true;
case R.id.rightNav:
return true;
case R.id.home:
Toast.makeText(this,"Click home", Toast.LENGTH_LONG);
return true;
default:
return super.onOptionsItemSelected(item);
}
}

Any one can help me, i'm new with android studio. Thanks in advance
I'm new to programming, and I want to add a settings menu button.
Like on the picture, my app doesn't show the three dots button.

viewPager.setAdapter(sectionsPagerAdapter);
TabLayout tabs = findViewById(R.id.tabs);
tabs.setupWithViewPager(viewPager);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.settings, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.vueSatellite:

What is my mistake ?
Or what do I have to add?
Tell me if there is missing information like the file AndroidManifest.xml for example.
Thanks
In your Activity just add
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
Hope it works.
I'm using android SearchView to have a search button in my action bar. I followed this tutorial from Google Developers on YouTube, and added a few tweaks based on my own needs. However, whenever I exit the search field that comes up when clicking the button, the search button disappears!
Here is my onCreateOptionsMenu and onOptionsItemSelected functions
onCreateOptionsMenu:
#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;
}
onOptionsItemSelected:
#Override
public boolean onOptionsItemSelected(final MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
switch (id) {
case R.id.action_settings:
// TODO: settings activity
break;
case R.id.action_logout:
FirebaseAuth.getInstance().signOut();
break;
case R.id.action_search:
// Initialize everything here, because it produces a NullPointerException if initialized in onCreateOptionsMenu
SearchView searchView = (SearchView) MenuItemCompat.getActionView(item);
SearchManager searchManager = (SearchManager)getSystemService(Context.SEARCH_SERVICE);
ComponentName componentName = new ComponentName(this, SearchableActivity.class);
searchView.setSearchableInfo(searchManager.getSearchableInfo(componentName));
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
return false;
}
});
break;
}
return super.onOptionsItemSelected(item);
}
And here's my menu_main.xml layout file
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
tools:context="com.magnus.inline.MainActivity">
<item
android:id="#+id/action_search"
android:icon="#drawable/ic_action_search"
android:title="Search"
app:actionViewClass="android.support.v7.widget.SearchView"
app:showAsAction="ifRoom|collapseActionView"/>
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:title="#string/action_settings"
app:showAsAction="never" />
<item
android:id="#+id/action_logout"
android:orderInCategory="200"
android:title="#string/action_logout"
app:showAsAction="never" />
And searchable.xml layout file
<?xml version="1.0" encoding="utf-8"?>
<searchable xmlns:android="http://schemas.android.com/apk/res/android"
android:label="#string/app_name"
android:hint="Search"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</searchable>
Images
EDIT:
I noticed that the only time the search button disappears is when I've pressed the options button while in "search mode"(see the last image in link). I have a feeling that when the options menu is displayed, the "action_search" is somehow converted to a options menu item, instead of an action bar item (?). For anyone asking, whenever I try to call MenuItemCompat.getActionView() of a searchview MenuItem in the onCreateOptionsMenu function, my app just crashes and says that it tries to perform it on a null object reference.

This is my first android app and I'm trying to add the Actionbar at the top but i cant seem to get it to work. All I get is a Blank blue bar across the top with no title and no overflow menu. To create this i used the instructions found here http://developer.android.com/training/appbar/index.html but even following the instructions to a T it doesn't seem to work. Even though I am not getting a compile error i was wondering if i was doing something wrong?

Try to add this code
getSupportActionBar().setTitle("Your Title");
Or you can customize your toolbar by defining one TextView inside the toolbar and assign your title like this.
<android.support.v7.widget.Toolbar
android:id="#+id/my_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
android:elevation="4dp"
android:theme="#style/ThemeOverlay.AppCompat.ActionBar"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Your Title"/>
</android.support.v7.widget.Toolbar>
Try this
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/main_content"

android:layout_height="match_parent">
<android.support.design.widget.AppBarLayout
android:id="#+id/id_appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:fitsSystemWindows="true">
<android.support.v7.widget.Toolbar
android:id="#+id/id_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways" />
</android.support.design.widget.AppBarLayout>
<RelativeLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
app:layout_behavior="#string/appbar_scrolling_view_behavior"/>
</RelativeLayout>

How to fix this problem and show menu in Toolbar ? thanks all dears <3
just override onCreateOptionsMenu like this in your MainPage.java
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main_menu, menu);
return true;
}
Don't use setSupportActionBar(toolbar)
I don't know why but this works for me.
toolbar = (Toolbar) findViewById(R.id.main_toolbar);
toolbar.setSubtitle("Test Subtitle");
toolbar.inflateMenu(R.menu.main_menu);
For menu item click do this:
toolbar.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
if (item.getItemId() == R.id.item1) {
// do something
} else if (item.getItemId() == R.id.filter) {
// do something
} else {
// do something
}
return false;
}
});
Will update the why part of this answer when I find a proper explanation.
Here is a fuller answer as a reference to future visitors. I usually use a support toolbar but it works just as well either way.
1. Make a menu xml
This is going to be in res/menu/main_menu.
Right click the res folder and choose New > Android Resource File.
Type main_menu for the File name.
Choose Menu for the Resource type.
Paste in the following content as a starter.
<?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_add"
android:icon="#drawable/ic_add"
app:showAsAction="ifRoom"
android:title="Add">
</item>
<item
android:id="#+id/action_settings"
app:showAsAction="never"
android:title="Settings">
</item>
</menu>
You can right click res and choose New image asset to create the ic_add icon.
2. Inflate the menu
In your activity add the following method.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_menu, menu);
return true;
}
3. Handle menu clicks
Also in your Activity, add the following method:
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.action_add:
addSomething();
return true;
case R.id.action_settings:
startSettings();
return true;
default:
return super.onOptionsItemSelected(item);
}
}

Android Menu Documentation
You need to override this code 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.main2, menu);
return true;
}
and set your toolbar like this:
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
You can still use the answer provided using Toolbar.inflateMenu even while using setSupportActionBar(toolbar).
I had a scenario where I had to move toolbar setup functionality into a separate class outside of activity which didn't by-itself know of the event onCreateOptionsMenu.
So, to implement this, all I had to do was wait for Toolbar to be drawn before calling inflateMenu by doing the following:
toolbar.post {
toolbar.inflateMenu(R.menu.my_menu)
}
Might not be considered very clean but still gets the job done.
First way:
In activitymain.xml
<androidx.appcompat.widget.Toolbar
android:id="#+id/maintoolbar"
android:layout_width="match_parent"
android:layout_height="56dp"/>
In MainActivity.java
import androidx.appcompat.widget.Toolbar;
private Toolbar toolbar;
Inside onCreate method-
toolbar=findViewById(R.id.maintoolbar);
setSupportActionBar(toolbar);
Inside your MainActivity class-
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.<your menu xml file name here>,menu);
return super.onCreateOptionsMenu(menu);
}
Second way :
//Remove setSupportActionBar(toolbar) and onCreateOptionmenu.
toolbar=findViewById(R.id.maintoolbar);
toolbar.inflateMenu(R.menu.<your menu xml file name here>);
Also you need this, to implement some action to every options of menu.
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.menu_help:
Toast.makeText(this, "This is teh option help", Toast.LENGTH_LONG).show();
break;
default:
break;
}
return true;
}
Without ActionBar but with Toolbar
If you want to use a Toolbar instead of the ActionBar, to setSupportActionBar is contradiction in principle as #RohitSingh answered above.
You need neither to use setSupportActionBar nor to override onCreateOptionsMenu and onOptionsItemSelected which are used for the ActionBar.
NoActionBar theme
Place a Toolbar in the layout xml
Prepare a menu xml
Toolbar#inflateMenu (alternatively you can also set a menu in the layout xml)
Toolbar#setOnMenuItemClickListener
Below is an example.
1. NoActionBar theme
(MaterialCompolent.DayNight theme is used in this sample)
<style name="Theme.AppTheme" parent="Theme.MaterialComponents.DayNight.NoActionBar">
2. Place a Toolbar in the layout
(MaterialToobar is used in this sample)
<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.google.android.material.appbar.MaterialToolbar
android:id="#+id/toolbar"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
3. Prepare a menu xml
<menu xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/item1"
android:title="#string/item1"
app:showAsAction="ifRoom" />
<item
android:id="#+id/item2"
android:title="#string/item2"
app:showAsAction="ifRoom" />
</menu>
4. Toolbar#inflateMenu
binding.toolbar.inflateMenu(R.menu.main); // binding is a ViewBinding
5. Toolbar#setOnMenuItemClickListener
Recent Android recommend to avoid to use switch to differentiate ids. Using a normal if ~ else if ~ else block is desirable. In addition to that, we can use lambda in Java 8.
binding.toolbar.setOnMenuItemClickListener(menuItem -> {
int itemId = menuItem.getItemId();
if (itemId == R.id.item1) {
// do something for item1
return true;
} else if (itemId == R.id.item2) {
// do something for item2
return true;
} else {
// if you do nothing, returning false should be appropriate.
return false;
}
});
Although I agree with this answer, as it has fewer lines of code and that it works:
How to set menu to Toolbar in Android
My suggestion would be to always start any project using the Android Studio Wizard. In that code you will find some styles:-
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
and usage is:
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:popupTheme="#style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
Due to no action bar theme declared in styles.xml, that is applied to the Main Activityin the AndroidManifest.xml, there are no exceptions, so you have to check it there.
<activity android:name=".MainActivity" android:screenOrientation="portrait"
android:theme="#style/AppTheme.NoActionBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
The Toolbar is not an independent entity, it is always a child
view in AppBarLayout that again is the child of
CoordinatorLayout.
The code for creating a menu is the standard code since day one,
that is repeated again and again in all the answers, particularly
the marked one, but nobody realized what is the difference.
BOTH:
Toolbar toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
AND:
How to set menu to Toolbar in Android
WILL WORK.
Happy Coding :-)
In XML add one line inside
<com.google.android.material.appbar.MaterialToolbar app:menu="#menu/main_menu"/>
In java file
Remove three line setSupportActionBar(toolbar); if (getSupportActionBar() != null) { getSupportActionBar().setTitle("Main Page"); }
add one line toolbar.setTitle("Main Page")
In your activity override this method.
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main_menu, menu);
return true;
}
This will inflate your menu below:
<?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_main_setting"
android:icon="#drawable/ic_settings"
android:orderInCategory="100"
app:showAsAction="always"
android:actionLayout="#layout/toolbar"
android:title="Setting" />
<item
android:id="#+id/menu_main_setting2"
android:icon="#drawable/ic_settings"
android:orderInCategory="200"
app:showAsAction="always"
android:actionLayout="#layout/toolbar"
android:title="Setting" />
</menu>
In my case, I'm using an AppBarLayout with a CollapsingToolbarLayout and the menu was always
being scrolled out of the screen, I solved my problem by switching android:actionLayout in menu's XML to
the toolbar's id. I hope it can help people in the same situation!

You can achieve this by two methods
Using XML
Using java
Using XML
Add this attribute to toolbar XML
app:menu = "menu_name"
Using java
By overriding onCreateOptionMenu(Menu menu)
public class MainActivity extends AppCompatActivity {
private Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.demo_menu,menu);
return super.onCreateOptionsMenu(menu);
}
}
for more details or implementating click on the menu go through this article

You don't actually need to touch the fragment/activity class at all to get a menu inside a toolbar. You can use Rohit Singh's method inside onViewCreated method
import androidx.appcompat.widget.Toolbar
...
override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
super.onViewCreated(view, savedInstanceState)
val toolbar = view.findViewById<Toolbar>(R.id.inbox_toolbar)
toolbar.inflateMenu(R.menu.inbox_menu)
}
or
simply define a app:menu element inside the toolbar,
<androidx.appcompat.widget.Toolbar ...
app:menu= "#menu/myMenu" ?>
Simple fix to this was setting showAsAction to always in menu.xml in res/menu
<?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/add_alarm"
android:icon="#drawable/ic_action_name"
android:orderInCategory="100"
android:title="Add"
app:showAsAction="always"
android:visible="true"/>
</menu>
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar;
toolbar = findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
getSupportActionBar().setDisplayShowTitleEnabled(false);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu_drawer,menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
int id = item.getItemId();
if (id == R.id.action_drawer){
drawerLayout.openDrawer(GravityCompat.END);
if (drawerLayout.isDrawerOpen(GravityCompat.END)) {
drawerLayout.closeDrawer(GravityCompat.END);
} else {
drawerLayout.openDrawer(GravityCompat.END);
}
}
return super.onOptionsItemSelected(item);
}

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="#style/AppTheme.AppBarOverlay">

android:id="#+id/toolbar"

</androidx.appcompat.widget.Toolbar>
private Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.my_toolbar);
*// here is where you set it to show on the toolbar*
setSupportActionBar(toolbar);
}
Well, you need to set support action bar setSupportActionBar(); and pass your variable, like so: setSupportActionBar(toolbar);
