JAVA (MainActivity.java)

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.content.Context;
import android.net.wifi.WifiManager;
import android.widget.CompoundButton;
import android.widget.Switch;
import android.widget.TextView;

public class EnableDisableWiFi extends AppCompatActivity {
    Switch wifibt;
    TextView textview;
    WifiManager wifimanager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_enable_disable_wi_fi);
        textview = (TextView)findViewById(R.id.textView1);

        wifibt = (Switch)findViewById(R.id.switch1);
        wifibt.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

                if(isChecked)
                {
                    textview.setText("WiFi ON");
                    EnableWiFi() ;
                }
                else {
                    textview.setText("WiFi OFF");
                    DisableWiFi();

                }
            }
        });
    }
    public void EnableWiFi(){
        wifimanager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
        wifimanager.setWifiEnabled(true);
    }
    public void DisableWiFi(){
        wifimanager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
        wifimanager.setWifiEnabled(false);

    }
}

import android.support.v7.app.AppCompatActivity;

import android.os.Bundle;

import android.content.Context;

import android.net.wifi.WifiManager;

import android.widget.CompoundButton;

import android.widget.Switch;

import android.widget.TextView;

public class EnableDisableWiFi extends AppCompatActivity {

Switch wifibt;

TextView textview;

WifiManager wifimanager;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_enable_disable_wi_fi);

textview = (TextView)findViewById(R.id.textView1);

wifibt = (Switch)findViewById(R.id.switch1);

wifibt.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

@Override

public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {

if(isChecked)

{

textview.setText("WiFi ON");

EnableWiFi() ;

}

else {

textview.setText("WiFi OFF");

DisableWiFi();

}

});

}

public void EnableWiFi(){

wifimanager = (WifiManager) getSystemService(Context.WIFI_SERVICE);

wifimanager.setWifiEnabled(true);

}

public void DisableWiFi(){

wifimanager = (WifiManager) getSystemService(Context.WIFI_SERVICE);

wifimanager.setWifiEnabled(false);

}

Now Open res -> layout -> activity_main.xml and then add following code :

XML (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"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
     >

    <Switch
        android:id="@+id/switch1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_above="@+id/switch1"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="42dp"
        android:text="WiFi OFF"
        android:textAppearance="?android:attr/textAppearanceLarge" />

</RelativeLayout>

<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"

android:paddingBottom="@dimen/activity_vertical_margin"

android:paddingLeft="@dimen/activity_horizontal_margin"

android:paddingRight="@dimen/activity_horizontal_margin"

android:paddingTop="@dimen/activity_vertical_margin"

<Switch

android:id="@+id/switch1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_centerHorizontal="true"

android:layout_centerVertical="true"

<TextView

android:id="@+id/textView1"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_above="@+id/switch1"

android:layout_centerHorizontal="true"

android:layout_marginBottom="42dp"

android:text="WiFi OFF"

android:textAppearance="?android:attr/textAppearanceLarge" />

</RelativeLayout>
