Extend Object and Change Method Parameter

Question

I create ImageViewProduct class which is extending ImageView class so i can store some variables in my ImageViewProduct object. But i can't get the ImageViewProduct's variable inside setOnClickListener method..

ImageViewProduct class :

public class ImageViewProduct extends ImageView {
    boolean toUpload = false;

    public ImageViewProduct(Context context) {
        super(context);
    }

    public void setToUpload(boolean toUpload) {
        this.toUpload = toUpload;
    }

    public boolean isToUpload() {
        return toUpload;
    }
}

MainActivity class :

ImageViewProduct ivProduct = new ImageViewProduct(this);
ivProduct.setToUpload(true)
ivProduct.setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(final View v) {
        Log.i("zihad", "is to upload : "+v.isToUpload());
    }
};

The log inside onClickListener is error cannot resolve method 'isToUpload()'. I've try to change the onClick(final View v) to onClick(final ImageViewProduct v) but error. How to fix it?

If you only ever apply this to an ImageViewProduct then you could cast v to an ImageViewProduct.

public void onClick(final View v) {
    ImageViewProduct productView = (ImageViewProduct) v;
    Log.i("zihad", "is to upload : "+productView.isToUpload());
}

More info on casting at this QnA.

Change

Log.i("zihad", "is to upload : "+v.isToUpload());

to

Log.i("zihad", "is to upload : "+ivProduct .isToUpload());

v is the variable of View. isToUpload is a method of ivProduct class
