It’s not possible programatically without rooting device.
But you can start NFC Settings Activity by intent action Settings.ACTION_NFC_SETTINGS for api level 16 and above. For api < 16 use Settings.ACTION_WIRELESS_SETTINGS
Previous selected answer suggests to use WIFI_SETTINGS but we can directly move to NFC_SETTINGS
Here’s the example :
android.nfc.NfcAdapter mNfcAdapter= android.nfc.NfcAdapter.getDefaultAdapter(v.getContext());
if (!mNfcAdapter.isEnabled()) {
AlertDialog.Builder alertbox = new AlertDialog.Builder(v.getContext());
alertbox.setTitle("Info");
alertbox.setMessage(getString(R.string.msg_nfcon));
alertbox.setPositiveButton("Turn On", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN) {
Intent intent = new Intent(Settings.ACTION_NFC_SETTINGS);
startActivity(intent);
} else {
Intent intent = new Intent(Settings.ACTION_WIRELESS_SETTINGS);
startActivity(intent);
}
}
});
alertbox.setNegativeButton("Close", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
}
});
alertbox.show();
}
