How do i compare the ID of my HashMap to my spinner value

Question

So if you see the code below, I have 3 arrays: one stores images, one stores values of my spinner and another stores the hashMap with the values of my images and the values of my spinner.

What I want to do is when I create an image by pressing my button say a husky image shows and when I select husky from my spinner it compares the two id's and if they are the same it will launch any code in the if statement.

Please use the below code snippet to check image view id with hashmap key and spinner text with hashmap value.

public class MainActivity extends Activity {
        private TextView tex_view;

        private Spinner mDogs;
        private ImageView mImageView;
        private Button mButton;
        private Random r;
        private TextView mTextView;
        private TextView mTextView2;

        //image arrays
        final Integer[] images = {R.drawable.home, R.drawable.mobile, R.drawable.sports,
                R.drawable.toys};

        final String[] dogs = {"Select Item", "husky", "kuvasz", "papillon", "vizsla"};

        Map<Integer, String> answers = new HashMap<Integer, String>() {{
            put(R.drawable.home, "husky");
            put(R.drawable.mobile, "kuvasz");
            put(R.drawable.sports, "papillon");
            put(R.drawable.toys, "vizsla");
        }};

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main);
            tex_view = findViewById(R.id.tex_view);
            mDogs = (Spinner) findViewById(R.id.spinner);
            mImageView = (ImageView) findViewById(R.id.pic1);
            mButton = (Button) findViewById(R.id.button);

            ArrayAdapter<String> ad1 = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, dogs);

            mDogs.setAdapter(ad1);

            mDogs.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {
                @Override
                public void onItemSelected(AdapterView<?> adapterView, View view, int i, long l) {
                    if (!mDogs.getSelectedItem().toString().equalsIgnoreCase("Select Item")) {
                        String imageID = String.valueOf(mImageView.getTag()); // imageView id
                        String selectedSpinnerText = mDogs.getSelectedItem().toString(); //selected Spinner text
                        for (Object name : answers.keySet()) {
                            String key = name.toString();
                            String value = answers.get(name);
                            if (selectedSpinnerText.equalsIgnoreCase(value) && imageID.equalsIgnoreCase(key)) {
                                tex_view.setText("Both image and Spinner text matches");
                                return;
                            } else {
                                tex_view.setText("Both image and Spinner text not matches");
                            }
                        }
                    }
                }

                @Override
                public void onNothingSelected(AdapterView<?> adapterView) {

                }
            });

            r = new Random();
            mButton.setOnClickListener(new View.OnClickListener() {

                @Override
                public void onClick(View view) {
                    //display random images
                    mButton.setText("Next");
                    int pos = r.nextInt(images.length);
                    mImageView.setImageResource(images[pos]);

                    mImageView.setTag(images[pos]);


                }
            });

        }
    }
