WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
wifi.setWifiEnabled(false); // true or false to activate/deactivate wifi

You also need to request the permission in your AndroidManifest.xml :

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

@Codii, I know this is old, but I am trying to do this within a dialogfragment. However, it says "Cannot resolve method 'getSystemService(java.lang.String)' I am not sure on what I need to do. And I have those permissions – James Robert Singleton Aug 11 '16 at 07:53
Worked for me thanks and you can check `wifi` if enable use `false` and if disable use `true` – SAYE Apr 28 '18 at 21:05

To enable/disable WiFi in your application you need to use WiFiManager class. Create an Object of WiFiManager class to get the services of WiFi.

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

wifi.setWifiEnabled(false);//Turn off Wifi

wifi.setWifiEnabled(true);//Turn on Wifi

And you have to put the following permissions in AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

<uses-permission android:name="android.permission.INTERNET" />

<uses-permission android:name="android.permission.CHANGE_WIFI_STATE"/>
<uses-permission android:name="android.permission.UPDATE_DEVICE_STATS" />

<uses-permission android:name="android.permission.WAKE_LOCK" />

            startActivityForResult(gpsOptionsIntent,0);

To enable/disable wifi from an app in Android Q (Android 10) use Settings Panel:

val panelIntent = Intent(Settings.Panel.ACTION_INTERNET_CONNECTIVITY)
startActivityForResult(panelIntent, 0)

On previous versions of Android this should work (appropriate permissions should be added to AndroidManifest file, see answers above):

(context?.getSystemService(Context.WIFI_SERVICE) as? WifiManager)?.apply { isWifiEnabled = true /*or false*/ }

Resulting code might look something like this:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
    val panelIntent = Intent(Settings.Panel.ACTION_INTERNET_CONNECTIVITY)
    startActivityForResult(panelIntent, 0)
} else {
    (context?.getSystemService(Context.WIFI_SERVICE) as? WifiManager)?.apply { isWifiEnabled = true /*or false*/ }
}

Where context is a reference to android.content.Context object.

try this

public void disableWifi(Context context, Boolean bool) {
    WifiManager wifi = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);

    if(bool)
        wifi.setWifiEnabled(false);
    else
        wifi.setWifiEnabled(true);
}

Although this might answer the question, one should also explain how and why. – BDL Aug 06 '15 at 10:33

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

        btn = (Switch) findViewById(R.id.switch1);
        btn.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                if (isChecked) {
                    toggleWiFi(true);
                    Toast.makeText(getApplicationContext(), "Wi-Fi Enabled!", Toast.LENGTH_LONG).show();
                } else {
                    toggleWiFi(false);
                    Toast.makeText(getApplicationContext(), "Wi-Fi Disabled!", Toast.LENGTH_LONG).show();
                }
            }
        });
    }

    public void toggleWiFi(boolean status){
        WifiManager wifiManager = (WifiManager)this.getSystemService(WIFI_SERVICE);
        if (status && !wifiManager.isWifiEnabled()) {
            wifiManager.setWifiEnabled(true);
        } else if (!status && wifiManager.isWifiEnabled()) {
            wifiManager.setWifiEnabled(false);
        }
    }
