builder.setMessage("Your GPS is disabled! Would you like to enable it?")
.setCancelable(false)
.setPositiveButton("Enable GPS",
new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int id) {
        moveConfigGPS();
    }
}).setNegativeButton("Do nothing",
new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int id) {
        dialog.cancel();
    }
});

AlertDialog alert = builder.create();
alert.show();

Update:

  /**
 * Check if GPS enabled or not
 * and request dialog to enable GPS.
 */
private void checkWhetherLocationSettingsAreSatisfied() {

    LocationRequest mLocationRequest = LocationRequest.create()
            .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
            .setInterval(1000)
            .setNumUpdates(2);

    final LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(mLocationRequest);
    builder.setAlwaysShow(true);
    builder.setNeedBle(true);
    SettingsClient client = LocationServices.getSettingsClient(this);
    Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());
    task.addOnSuccessListener(this, new OnSuccessListener<LocationSettingsResponse>() {
        @Override
        public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
            Log.d(TAG, "onSuccess() called with: locationSettingsResponse = [" + locationSettingsResponse + "]");
            hasLocationPermission();

        }
    });
    task.addOnFailureListener(this, new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            Log.d(TAG, "onSuccess --> onFailure() called with: e = [" + e + "]");
            if (e instanceof ResolvableApiException) {
                // Location settings are not satisfied, but this can be fixed
                // by showing the user a dialog.
                try {
                    // Show the dialog by calling startResolutionForResult(),
                    // and check the result in onActivityResult().
                    ResolvableApiException resolvable = (ResolvableApiException) e;
                    resolvable.startResolutionForResult(BaseActivity.this,
                            Constants.REQUEST_CHECK_SETTINGS);
                } catch (IntentSender.SendIntentException e) {

                    e.printStackTrace();
                }
            }

        }
    });
}



@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == Constants.REQUEST_CHECK_SETTINGS) {

        // Make sure the request was successful
        if (resultCode == RESULT_OK) {

            hasLocationPermission();

        } else {
            //User clicks No
        }
    }

}

I think you want to turn on GPS location with one click like Google do.

To prompt the user for permission to modify the location settings, call startResolutionForResult(Activity, int). This method brings up a dialog asking for the user's permission to modify location settings.
