public class enableordisablewifiusingbutton extends AppCompatActivity {
    TextView WifiState;


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

        WifiState = (TextView)findViewById(R.id.wifistate);
        Button OnWifi = (Button)findViewById(R.id.onwifi);
        Button OffWifi = (Button)findViewById(R.id.offwifi);

        this.registerReceiver(this.WifiStateChangedReceiver,
                new IntentFilter(WifiManager.WIFI_STATE_CHANGED_ACTION));

        OnWifi.setOnClickListener(new Button.OnClickListener(){

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                WifiManager wifiManager = (WifiManager)getBaseContext().getSystemService(Context.WIFI_SERVICE);
                wifiManager.setWifiEnabled(true);
            }});

        OffWifi.setOnClickListener(new Button.OnClickListener(){

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                WifiManager wifiManager = (WifiManager)getBaseContext().getSystemService(Context.WIFI_SERVICE);
                wifiManager.setWifiEnabled(false);
            }});
    }

    private BroadcastReceiver WifiStateChangedReceiver
            = new BroadcastReceiver(){

        @Override
        public void onReceive(Context context, Intent intent) {
            // TODO Auto-generated method stub

            int extraWifiState = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE ,
                    WifiManager.WIFI_STATE_UNKNOWN);

            switch(extraWifiState){
                case WifiManager.WIFI_STATE_DISABLED:
                    WifiState.setText("WIFI STATE DISABLED");
                    break;
                case WifiManager.WIFI_STATE_DISABLING:
                    WifiState.setText("WIFI STATE DISABLING");
                    break;
                case WifiManager.WIFI_STATE_ENABLED:
                    WifiState.setText("WIFI STATE ENABLED");
                    break;
                case WifiManager.WIFI_STATE_ENABLING:
                    WifiState.setText("WIFI STATE ENABLING");
                    break;
                case WifiManager.WIFI_STATE_UNKNOWN:
                    WifiState.setText("WIFI STATE UNKNOWN");
                    break;
            }

        }};
}

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

XML (activity_main.xml)

<android.support.constraint.ConstraintLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:orientation="vertical"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    >

    <TextView
        android:id="@+id/wifistate"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:layout_constraintBottom_toTopOf="@+id/onwifi"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <Button
        android:id="@+id/onwifi"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Turn Wifi On"
        app:layout_constraintBottom_toTopOf="@+id/offwifi"
        app:layout_constraintTop_toBottomOf="@+id/wifistate" />

    <Button
        android:id="@+id/offwifi"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="32dp"
        android:text="Turn Wifi Off"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/onwifi" />
</android.support.constraint.ConstraintLayout>

Output:

Finally, run this project.

This is how application look like.
