In this tutorial we will add items in actionbar/toolbar, 3-dot menu in actionbar/toolbar and handle item clicks. There will be three items in menu you can add as many as you want. One item will be displayed on action bar with icon, other two items will be displayed by clicking 3-dot menu.

Step 3: Create menu.xml by clicking “menu>New>Menu resource file”
Step 4: Enter an icon in drawable folder by clicking “drawable>New>Image Asset”

xmlns:tools="http://schemas.android.com/tools"

android:gravity="center"
tools:context=".MainActivity">
<TextView
android:text="Hellow World!"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
</LinearLayout>

package com.jigopost.myapplication;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;
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) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id==R.id.action_one){
Toast.makeText(this, "Item One Clicked", Toast.LENGTH_SHORT).show();
return true;
}
else if (id==R.id.action_two){
Toast.makeText(this, "Item Two Clicked", Toast.LENGTH_SHORT).show();
return true;
