How to track randomly displayed drawable to cross check with user submitted answer - android-imageview

Question

I am trying to create an application where a random image is displayed(Working), and the user selects from a dropdown list the displayed image and this is checked to see if it is correct or not
I am not sure how to track the image displayed as I need something to reference in my if statement
See below my attempt but it returns null on the locationOfCorrectAnswer
public class IdentifyTheBrandActivity extends AppCompatActivity implements AdapterView.OnItemClickListener,
AdapterView.OnItemSelectedListener { String[] Brands = { "Audi", "Bentley", "BMW" };
Button SubmitButton;
ImageView imageView;
int[] images;
int chosenCar = 0;
int locationOfCorrectAnswer;
String[] answers = new String[3];
ArrayList<String> carBrands = new ArrayList<>();
public void brandChosen(View view) {
if (view.getTag().toString().equals(Integer.toString(locationOfCorrectAnswer))){
Toast.makeText(getApplicationContext(), "Correct", Toast.LENGTH_LONG).show();
}else{
Toast.makeText(getApplicationContext(), "Wrong it was " + carBrands.get(chosenCar), Toast.LENGTH_LONG).show();
}
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_identify_the_brand);
imageView = findViewById(R.id.RandomImage);
imageView.setTag("bg");
carBrands.add("Audi");
carBrands.add("Bentley");
carBrands.add("BMW");
images = new int[]{R.drawable.audi_a3_2010_27_17_200_20_4_77_56_169_21_fwd_5_4_4dr_igm, R.drawable.bentley_bentayga_2017_229_21_600_60_12_78_68_202_12_awd_5_4_suv_cce,
R.drawable.bmw_6_series_2014_82_18_310_30_6_74_53_192_20_rwd_4_2_convertible_mua};
Random random = new Random();
chosenCar = random.nextInt(images.length);
locationOfCorrectAnswer = random.nextInt(images.length);
imageView.setBackgroundResource(images[chosenCar]);
int incorrectAnswerLocation;
//Get a random between 0 and images.length-1
//int imageId = (int) (Math.random() * images.length);
Spinner spin = (Spinner) findViewById(R.id.spinner);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, Brands);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spin.setAdapter(adapter);
spin.setOnItemSelectedListener(this);
}
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
}
#Override
public void onItemSelected(AdapterView<?> parent, View view, int position, long l) {
Toast.makeText(getApplicationContext(), "Selected Brand: " + Brands[position]
,Toast.LENGTH_SHORT).show();
/*SubmitButton = findViewById(R.id.SubmitButton);
SubmitButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
// Toast.makeText(getApplicationContext(), "Correct Brand", Toast.LENGTH_SHORT).show();
}
});*/
}
#Override
public void onNothingSelected(AdapterView<?> adapterView) {
}
}
I'm not sure why my brandChosen method is returning null? I believe this is the approach that will work
