I'm creating an android application which uses google maps, so I need the GPS to turn on, I have an splash activity where im trying to check if GPS is on. The thing is that I can check if GPS is on or off, but I don't know how to create a dialog so the user can turn the GPS on. I saw in several apps that when you open it, it shows u a Dialog which askes the user if the GPS should be turned on, and if the user chose yes the GPS turned on automatically. And if the user chose no, the dialog closed and reopened again. This process repeats itself until the user choses yes. How can I achieve something like this?
Here is what I have this far.:
public class ActividadSplash extends AppCompatActivity {
private static final long SPLASH_SCREEN_DELAY = 6000;
private ProgressBar barra;
private int progressStatus = 0;
private Handler handler = new Handler();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splash_screen);
final LocationManager manager = (LocationManager)getApplicationContext().getSystemService (Context.LOCATION_SERVICE );
if(!manager.isProviderEnabled( LocationManager.GPS_PROVIDER)){
CheckEnableGPS();
}
else{
barra = (ProgressBar) findViewById(R.id.barraProgreso2);
barra.setScaleY(3f);
new Thread(new Runnable() {
public void run() {
while (progressStatus < 100) {
progressStatus += 1;
//Update progress bar with completion of operation
handler.post(new Runnable() {
public void run() {
barra.setProgress(progressStatus);
if(progressStatus==100){
finish();
ParseUser usuario= ParseUser.getCurrentUser();
if(usuario!=null){
Intent intento = new Intent(getApplicationContext(), DrawerPrincipal.class);
intento.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intento.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intento);
}else{
Intent intento = new Intent(getApplicationContext(), ActividadLogin.class);
intento.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intento.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
startActivity(intento);
}
}
// textView.setText(progressStatus+"/"+progressBar.getMax());
}
});
try {
// Sleep for 200 milliseconds.
//Just to display the progress slowly
Thread.sleep(20);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}).start();
}
}
private void CheckEnableGPS() {
String provider = Settings.Secure.getString(getContentResolver(),
Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(!provider.equals("")){
//GPS Enabled
}else{
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle("Enable GPS"); // GPS not found
builder.setMessage("The app needs GPS to be enabled do you want to enable it in the settings? "); // Want to enable?
builder.setPositiveButton("Settings", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialogInterface, int i) {
startActivity(new Intent(android.provider.Settings.ACTION_LOCATION_SOURCE_SETTINGS));
}
});
builder.setNegativeButton("Exit", new DialogInterface.OnClickListener() {

}

}

.setExpirationDuration(10 * 1000) // After 10 seconds
.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
builder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest);
// set builder to always true (Shows the dialog after never operation too)
builder.setAlwaysShow(true);
// Then check whether current location settings are satisfied:
PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi.checkLocationSettings(mGoogleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
@Override
public void onResult(LocationSettingsResult result) {
final Status status = result.getStatus();
