Answer 1

You can use the WifiManager class to get the state of Wi-Fi.

See this question for opening Wi-Fi settings. And this question for GPS status.

Answer 2

ConnectivityManager conMan = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

//mobile
State mobile = conMan.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).getState();

//wifi
State wifi = conMan.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState();

Answer 3

To check if the device is connected via mobile or wifi you can use this code:

ConnectivityManager conMan = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);

//mobile
State mobile = conMan.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).getState();

//wifi
State wifi = conMan.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState();

and then use it like that:

if (mobile == NetworkInfo.State.CONNECTED || mobile == NetworkInfo.State.CONNECTING) {
    //mobile
} else if (wifi == NetworkInfo.State.CONNECTED || wifi == NetworkInfo.State.CONNECTING) {
    //wifi
}

Answer 4

private boolean isNetworkAvailable() {
    ConnectivityManager connManager = (ConnectivityManager) 
            getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo activeNetworkInfo = connManager.getActiveNetworkInfo();
    return activeNetworkInfo.isConnected();
}

public void onClick(DialogInterface dialog, int id) {
    // ...
    if (isNetworkAvailable()) {
        t3.setText("The Internet is available");
    } else {
        t3.setText("internet is not available");
    }
}
