How to declare an ImageView in a class?

I have an InsertStampActivity witch contains 3 EditText and an ImageView received from phone's gallery. I need to create a class with those 3 editText and the image.

Here is my class: 

public class Timbru {
    private int year;
    private String country;
    private float value;    }

I have also implement construtor, getters and setters for each parameter.

My question is how to implement the imageView in my class for further operations?

You could declare your image in your class as a String.

public class Timbru {
   private int year;
   private String country;
   private float value;
   private String image;
}

Then, in your activity, convert the ImageView to a String like this:

Bitmap bitmap=BitmapFactory.decodeResource(getResources(), R.drawable.yourImage);
ByteArrayOutputStream stream=new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.PNG, 90, stream);
byte[] image=stream.toByteArray();


String imageToStoreInYourClass = Base64.encodeToString(image, 0);

And then you can also convert from the String to Bitmap back like this:

byte[] decodedString = Base64.decode(encodedImage, Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
