Switch Wifi On/Off in a toggle button Android

Question

I know that to switch Wi-Fi state I have to do this:

wifiManager = (WifiManager) this.getSystemService(Context.WIFI_SERVICE); 
wifiManager.setWifiEnabled(true);
wifiManager.setWifiEnabled(false);

and write the following permissions:

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

I made two radio buttons (on/off) and they goes but it's not the best solution, so I want to create a toggle button. How can I put the code inside a toggle button?

Answer 1

You could do this in your Activity :

public class MyActivity extends Activity {

    private ToggleButton btn;
    private WifiManager wifiManager;

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

        wifiManager = (WifiManager)this.getSystemService(Context.WIFI_SERVICE);

        btn = (ToggleButton) findViewById(R.id.btn_id);
        btn.setChecked(wifiManager.isWifiEnabled());

        btn.setOnCheckedChangeListener(new CompoundButton.OnCheckedChangeListener() {

            @Override
            public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
                wifiManager.setWifiEnabled(isChecked);
            }

        });
    }
}
