Android, adding a menu to an activity

I want to add a menu to my main activity. When I start my application, all shows up correctly but the menu. What I'm doing wrong?
This is my activity_main.xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<WebView
android:id="#+id/activity_main_webview"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
This is part of the MainActivity.java:
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu_main, menu);
return super.onCreateOptionsMenu(menu);
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()){
case R.id.menu1:
Toast.makeText(this, "Clicked Menu 1", Toast.LENGTH_SHORT).show();
break;
case R.id.menu2:
Toast.makeText(this, "Clicked Menu 2", Toast.LENGTH_SHORT).show();
break;
default:
break;
}
return super.onOptionsItemSelected(item);
}
This is the styles.xml
<resources>
<style name="AppTheme" parent="android:Theme.DeviceDefault.Light">
<item name="android:statusBarColor">#android:color/black</item>
<item name="android:windowActionBar">false</item>
<item name="android:windowNoTitle">true</item>
</style>
</resources>
And for last, this is the menu_main.xml:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/menu1"
android:title="Option 1" />
<item
android:id="#+id/menu2"
android:title="Optiion 2" />
</menu>

Is your activity extending from AppCompatActivity?
Extending from AppCompatActivity allows you to set the toolbar using the method setSupportActionBar check this first.
If not, the 'easy' way would be to use a theme that by default provides you an AppBar (ending with .DarkActionBar for example)

You need to create a toolbar in your activity_main.xml and in your MainActivity.java in the onCreate add this:
setSupportActionBar(yourToolbarId);

Is there a way to make the destinations in a BottomNavigationView appear evenly distributed across its length in landscape mode

It would be even better if the text appears below the respective icon while the icons are evenly distributed.
Currently, the items appear stacked in landscape mode.
Current implementation:
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/bottom_nav_bar"
style="#style/Widget.MaterialComponents.BottomNavigationView.Colored"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:itemIconTint="#color/selector_icon_tint_bottom_nav"
app:itemTextColor="#color/selector_icon_tint_bottom_nav"
app:labelVisibilityMode="labeled"
app:menu="#menu/bottom_nav" />

Try this out I hope it will work.Its working for me
<FrameLayout
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="wrap_content">
<com.google.android.material.bottomnavigation.BottomNavigationView
android:id="#+id/bottom_navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="bottom"
android:background="#color/colorPrimary"
app:labelVisibilityMode="labeled"
app:itemIconTint="#color/white"
app:itemTextColor="#color/white"
app:menu="#menu/bottom_navigation_menu" />
</FrameLayout>
Make a menu directory under res and in that directory make an XML layout
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item
android:id="#+id/navigation_home"
android:icon="#drawable/ic_home"
android:title="Home" />
<item
android:id="#+id/navigation_profile"
android:icon="#drawable/ic_profile"
android:title="Profile" />
<item
android:id="#+id/navigation_about"
android:icon="#drawable/ic_aboutUs"
android:title="About Us" />
<item
android:id="#+id/navigation_logout"
android:icon="#drawable/ic_logout"
android:title="Logout" />
</menu>
In main activity implement BottomNavigationView.OnNavigationItemSelectedListener and implements its all method then you can do your desire action on each icon
bottomNavigationView = findViewById(R.id.bottom_navigation_view);
bottomNavigationView.setOnNavigationItemSelectedListener(this);
}
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
switch (item.getItemId()) {
case R.id.navigation_home:
Toast.makeText(this, "Home", Toast.LENGTH_SHORT).show();
return true;
case R.id.navigation_profile:
Toast.makeText(this, "Profile", Toast.LENGTH_SHORT).show();
return true;
case R.id.navigation_about:
Toast.makeText(this, "About Us", Toast.LENGTH_SHORT).show();
return true;
case R.id.navigation_logout:
Toast.makeText(this, "Logout", Toast.LENGTH_SHORT).show();
return true;
}
return false;
}

BottomAppBar Missing Menu Items - Not Showing up all the menu items

I'm trying to implement the BottomAppBar menu widget in android, however on implementation I can see only the menu icon and cannot see all the other menu items(settings, search).
I changed the parent style theme to: Theme.MaterialComponents.Light.NoActionBar
Tried using inflater to inject the menu items in the bottom position and BottomAppbar widget.
Repo link of android project:
https://github.com/tracebackerror/StuddyBuddy/
Expected Output using BottomAppMenu :
Current Menu Output:
bottomappbar_menu.xml
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android"

<item

android:icon="#drawable/ic_search_black_24dp"

Just use:
<com.google.android.material.bottomappbar.BottomAppBar
app:menu="#menu/bottomappbar_menu"
.../>
You can also use:
bottomAppBar.replaceMenu(R.menu.bottomappbar_menu);
In this case you have to handle menu options using:
bottomAppBar.setOnMenuItemClickListener(new OnMenuItemClickListener() {
#Override
public boolean onMenuItemClick(MenuItem item) {
//....
return true;
}
});
Otherwise if you want to setup the menu callbacks in a similar way to Toolbar as described by Mike in the comments you have to:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_home);
//...
BottomAppBar bottomAppBar = findViewById(R.id.bottom_app_bar);
setSupportActionBar(bottomAppBar);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.bottomappbar_menu, menu);
return true;
}

Android How to remove the second title in my actionbar?

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main_menu);
Toolbar toolbar = (Toolbar)findViewById(R.id.mytoolbar);

What can i do to remove this error

You have given titles two times either you want to remove upper one remove TextView which is inside Toolbar and setTitle of toolbar.
otherwise remove title from the Toolbar

You can remove title with help of
getSupportActionBar().setDisplayShowTitleEnabled(false);

Creating a button in Android Toolbar

How can I create a button inside Android's Toolbar that looks like this iOS example?

ToolBar with Button Tutorial
1 - Add library compatibility inside build.gradle
dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:21.0.3'
}
2 - Create a file name color.xml to define the Toolbar colors
<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="ColorPrimary">#FF5722</color>
<color name="ColorPrimaryDark">#E64A19</color>
</resources>
3 - Modify your style.xml file
<resources>
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="colorPrimary">#color/ColorPrimary</item>
<item name="colorPrimaryDark">#color/ColorPrimaryDark</item>
<!-- Customize your theme here. -->
</style>
</resources>
4 - Create a xml file like tool_bar.xml
<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorPrimary"
android:elevation="4dp" />
5 - Include the Toolbar into your main_activity.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".MainActivity">
<include
android:id="#+id/tool_bar"
layout="#layout/tool_bar" />
<TextView
android:layout_below="#+id/tool_bar"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginTop="#dimen/TextDimTop"
android:text="#string/hello_world" />
</RelativeLayout>
6 - Then, put it inside your MainActivity class
package com.example.hp1.materialtoolbar;
import android.support.v4.widget.DrawerLayout;
import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.support.v7.app.ActionBarDrawerToggle;
import android.support.v7.widget.LinearLayoutManager;
import android.support.v7.widget.RecyclerView;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.view.MotionEvent;
import android.view.View;
import android.widget.Toast;
/* When using AppCompat support library
* (you need to extend Main Activity to
* ActionBarActivity)
* ActionBarActivity has deprecated, use AppCompatActivity
*/
public class MainActivity extends ActionBarActivity {
// Declaring the Toolbar Object
private Toolbar toolbar;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main_activity);
// Attaching the layout to the toolbar object
toolbar = (Toolbar) findViewById(R.id.tool_bar);
// Setting toolbar as the ActionBar with setSupportActionBar() call
setSupportActionBar(toolbar);
}
#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;
}
#Override
public boolean onOptionsItemSelected(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();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
7 - And finally, add your "Button Items" to the menu_main.xml inside of /res/menu/ directory
<?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"
xmlns:tools="http://schemas.android.com/tools"
tools:context=".MainActivity">
<item
android:id="#+id/action_settings"
android:orderInCategory="100"
android:title="#string/action_settings"
app:showAsAction="never" />
<item
android:id="#+id/action_search"
android:orderInCategory="200"
android:title="Search"
android:icon="#drawable/ic_search"
app:showAsAction="ifRoom"/>
<item
android:id="#+id/action_user"
android:orderInCategory="300"
android:title="User"
android:icon="#drawable/ic_user"
app:showAsAction="ifRoom" />
</menu>

Toolbar customization can done by following ways
write button and textViews code inside toolbar as shown below
<android.support.v7.widget.Toolbar
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="#+id/app_bar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
>
<Button
android:layout_width="wrap_content"
android:layout_height="#dimen/btn_height_small"
android:text="Departure"
android:layout_gravity="right"
/>
</android.support.v7.widget.Toolbar>
Other way is to use item menu as shown below
#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;
}

Another possibility is to set the app:actionViewClass attribute in your menu:
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="#+id/get_item"
android:orderInCategory="1"
android:text="Get"
app:showAsAction="always"
app:actionViewClass="android.support.v7.widget.AppCompatButton"/>
</menu>
In your code you can access this button after the menu was inflated:
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater menuInflater = getMenuInflater();
menuInflater.inflate(R.menu.sample, menu);
MenuItem getItem = menu.findItem(R.id.get_item);
if (getItem != null) {
AppCompatButton button = (AppCompatButton) getItem.getActionView();
//Set a ClickListener, the text,
//the background color or something like that
}
return super.onCreateOptionsMenu(menu);
}

I have added text in ToolBar :
menu_skip.xml
<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=".MainActivity">
<item
android:id="#+id/action_settings"
android:title="#string/text_skip"
app:showAsAction="never" />
</menu>
MainActivity.java
#Override
boolean onCreateOptionsMenu(Menu menu) {
inflater = getMenuInflater();
inflater.inflate(R.menu.menu_otp_skip, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
// action with ID action_refresh was selected
case R.id.menu_item_skip:
Toast.makeText(this, "Skip selected", Toast.LENGTH_SHORT)
.show();
break;
default:
break;
}
return true;
}

They are called menu items or action buttons in toolbar/actionbar. Here you have Google tutorial how it works and how to add them
https://developer.android.com/training/basics/actionbar/adding-buttons.html

You can actually put anything inside a toolbar. See the below code.
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:background="#color/colorPrimary">
</android.support.v7.widget.Toolbar>
Between the above toolbar tag you can put almost anything. That is the benefit of using a Toolbar.
Source: Android Toolbar Example

You could use actionLayout from the support library.
menu.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/button_item"
android:title=""
app:actionLayout="#layout/button_layout"
app:showAsAction="always"
/>
</menu>
button_layout.xml
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="match_parent"
android:orientation="horizontal">
<Button
android:id="#+id/button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:layout_centerVertical="true"
/>
</RelativeLayout>
Activity.java
#Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.menu, menu);
MenuItem item = menu.findItem(R.id.button_item);
Button btn = item.getActionView().findViewById(R.id.button);
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText(MainActivity.this, "Toolbar Button Clicked!", Toast.LENGTH_SHORT).show();
}
});
return true;
}

I was able to achieve that by wrapping Button with ConstraintLayout:
<androidx.coordinatorlayout.widget.CoordinatorLayout 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"
android:layout_width="match_parent"
android:layout_height="match_parent">
<com.google.android.material.appbar.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:elevation="0dp">
<androidx.appcompat.widget.Toolbar
android:id="#+id/top_toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#color/white_color">
<androidx.constraintlayout.widget.ConstraintLayout
android:layout_width="match_parent"
android:layout_marginTop="10dp"
android:layout_height="wrap_content">
<TextView
android:id="#+id/cancel"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/cancel"
android:layout_marginStart="5dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<Button
android:id="#+id/btn_publish"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="#string/publish"
android:background="#drawable/button_publish_rounded"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
android:layout_marginEnd="10dp"
app:layout_constraintLeft_toRightOf="#id/cancel"
tools:layout_editor_absoluteY="0dp" />
</androidx.constraintlayout.widget.ConstraintLayout>
</androidx.appcompat.widget.Toolbar>
</com.google.android.material.appbar.AppBarLayout>
</androidx.coordinatorlayout.widget.CoordinatorLayout>
You may create a drawable resourcebutton_publish_rounded, define the button properties and assign this file to button's android:background property:
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">
<solid android:color="#color/green" />
<corners android:radius="100dp" />
</shape>
