Create OptionMenuActivity 

OptionMenuActivity.Java 

package com.example.customdrawer;

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.widget.Toast;

public class OptionMenuActivity extends AppCompatActivity {

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

    @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. 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.home) {
            Toast.makeText(getApplicationContext(),"home",Toast.LENGTH_LONG).show();
        }
       else if (id == R.id.about) {
            Toast.makeText(getApplicationContext(),"about us",Toast.LENGTH_LONG).show();
        }
        else if (id == R.id.contact) {
            Toast.makeText(getApplicationContext(),"contact us",Toast.LENGTH_LONG).show();
        }
        return super.onOptionsItemSelected(item);
    }
}


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"
    xmlns:tools="http://schemas.android.com/tools"
    tools:context="com.example.myapplication.MainActivity">
    <item
        android:id="@+id/home"
        android:orderInCategory="100"
        android:title="HOME"
        app:showAsAction="never" />

    <item
        android:id="@+id/about"
        android:orderInCategory="100"
        android:title="About US"
        app:showAsAction="never" />

    <item
        android:id="@+id/contact"
        android:orderInCategory="100"
        android:title="Contact US"
        app:showAsAction="never" />
</menu>

package com.example.customdrawer;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
import android.widget.PopupMenu;
import android.widget.Toast;

public class Popupmenuactivity extends AppCompatActivity {

    Button btn;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_popupmenuactivity);
        btn = findViewById(R.id.btnpopmenu);
        btn.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                PopupMenu popup = new PopupMenu(Popupmenuactivity.this, btn);
                popup.getMenuInflater().inflate(R.menu.menu, popup.getMenu());
                popup.show();
                popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
                    @Override
                    public boolean onMenuItemClick(MenuItem item) {
                                             Toast.makeText(getApplicationContext(),"You Clicked : " + item.getTitle(), Toast.LENGTH_SHORT).show();
                                              return true;

                    }
                });
            }

        android:layout_height="wrap_content"
        android:id="@+id/lstcontext"
        >


    </ListView>

</LinearLayout>
Create popmenu.xml file :-

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:id="@+id/call"
        android:title="Call" />
    <item android:id="@+id/sms"
        android:title="SMS" />
</menu>

package com.example.testapp;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.view.ContextMenu;
import android.view.MenuInflater;
import android.view.MenuItem;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class ContextMenuActivity extends AppCompatActivity {

    ListView lst;
    String arr[] = {"JAY","MANISH","RAVI","SUNIL","PANKAJ"};
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_context_menu);
        lst = findViewById(R.id.lstcontext);
        ArrayAdapter aa = new ArrayAdapter(getApplicationContext(), android.R.layout.simple_list_item_1,arr);
        lst.setAdapter(aa);
        registerForContextMenu(lst);
    }
    @Override
    public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo)
    {
        super.onCreateContextMenu(menu, v, menuInfo);
        MenuInflater inflater = getMenuInflater();
        inflater.inflate(R.menu.popupmenu, menu);
        menu.setHeaderTitle("Select The Action");
    }
    @Override
    public boolean onContextItemSelected(MenuItem item){
        if(item.getItemId()==R.id.call){
            Toast.makeText(getApplicationContext(),"calling code",Toast.LENGTH_LONG).show();
        }
        else if(item.getItemId()==R.id.sms){
            Toast.makeText(getApplicationContext(),"sending sms code",Toast.LENGTH_LONG).show();

The uncontrolled input is similar to the traditional HTML form inputs. The DOM itself handles the form data. Here, the HTML elements maintain their own state that will be updated when the input value changes. To write an uncontrolled component, you need to use a ref to get form values from the DOM. In other words, there is no need to write an event handler for every state update. You can use a ref to access the input field value of the form from the DOM. Example of Uncontrolled Form Input:- import React from "react" ; export class Info extends React . Component {     constructor ( props )     {         super ( props );         this . fun = this . fun . bind ( this ); //event method binding         this . input = React . createRef ();...
