Android Toolbar Example.
Toolbar is a complete replacement to Android ActionBar.ToolBar works well with apps targeted to API 21 and above and it is introduced after lollipop release.

Toolbar may contain a combination of the following optional elements:

• Using the Navigation button.
• Using the logo Image.
• Using the title and subtitle.

Implementing the Navigation button and icon on Toolbar.

Open android studio and create a new project.
File => New => New Project => Configure your new project => Select the form factor yours app will run on => Add an Activity to Mobile => Customize the Activity => Finish.

Create Xml file in project.    
Open => app => res => layout - activity_main.xml.

<?xml version="1.0" encoding="utf-8"?>
<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="laptop.example.com.toolbaricon.MainActivity">

    <android.support.v7.widget.Toolbar
        android:id="@+id/toolbar"
        android:layout_width="match_parent"
        android:layout_height="58dp"
        android:background="@color/colorPrimary"
        android:minHeight="?attr/actionBarSize"></android.support.v7.widget.Toolbar>
</RelativeLayout>
Create Xml file in project.
Open => app => 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"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context=".MainActivity">
    <item
        android:id="@+id/action_search"
        android:icon="@drawable/search"
        android:title="Search"
        app:actionViewClass="android.support.v7.widget.SearchView"
        app:showAsAction="ifRoom|collapseActionView" />
    <item
        android:id="@+id/action_setting"
        android:icon="@drawable/setting"
        android:orderInCategory="300"
        android:title="Setting"
        app:showAsAction="ifRoom"></item>
</menu>

Create the Java file in project.
Open app => main => src = MainActivity.java

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Toast;

public class MainActivity extends AppCompatActivity {
    Toolbar toolbar;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ToolBar();

    }

    private void ToolBar() {
        toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);
        getSupportActionBar().setDisplayShowTitleEnabled(false);
        toolbar.setTitle("");
        toolbar.setNavigationIcon(R.drawable.hamburger);
        toolbar.setNavigationOnClickListener(
                new View.OnClickListener() {
                    @Override
                    public void onClick(View v) {
                        Toast.makeText(MainActivity.this, "Click App Logo", Toast.LENGTH_SHORT).show();
                    }
                }

        );
    }

    @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);

        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.

        switch (item.getItemId()) {
            case R.id.action_search:
                Toast.makeText(MainActivity.this, "I am Search", Toast.LENGTH_LONG).show();
                break;
            case R.id.action_setting:
                Toast.makeText(MainActivity.this, "I am Setting", Toast.LENGTH_LONG).show();
                break;
            default:
                break;
        }
        return super.onOptionsItemSelected(item);
    }
}
