    String SingleItem= (String) getItem(position);
    final TextView text =(TextView)CustomView.findViewById(R.id.Itemname);
    final ImageView Image= (ImageView)CustomView.findViewById(R.id.icon);

            Image.setImageResource(R.drawable.fish);
            Pricetag.setText("Rs 100");
            break;
        default:
            Image.setImageResource(R.drawable.myimage);
            Pricetag.setText("Rs 0.00");
            break;
    }

    final Button Buybutton= (Button)CustomView.findViewById(R.id.BuyButton);

    toast = Toast.makeText(getContext(), "", Toast.LENGTH_LONG);
    Buybutton.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            toast.setText("Bought");
            toast.show();

        }
    });

    text.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            toast.setText(text.getText().toString());
            toast.show();

        }
    });
    return CustomView;
 }
}

Answer 1

For the record, there should be a better way to do this, using food-id or other approach to prevent this, but based on your request, here we go:

1- in getView() when you get a reference on the button ie:

final Button Buybutton= (Button)CustomView.findViewById(R.id.BuyButton);

do a one more step:

Buybutton.setTag(10);

10 here could be any other number, and you need to find a way to determine which number to use for each button, also it could be a string , ex value of SingleItem

Buybutton.setTag(SingleItem);

2- at onClick() you need to find out what the value assign to the view (button) and based on this value call the proper method:

@Override
public void onClick(View v) {
    if (v.getTag().toString().equals("xxxxx")){
        doSomething();
    }else if (v.getTag().toString().equals("yyyy")){
        doAnotherThing();
    }else if (v.getTag().toString().equals("zzzzz")){
        doSomething12();
    }
    //and so on...
}

this approach used String as value in setTag() and getTag() if you use integers, just replace the condition as belwo:

if (Integer.parseInt(v.getTag().toString()) == 10)

EDIT:

If i understand well, then you need to:

Buybutton.setTag(SingleItem);

and onClick():

@Override
public void onClick(View v) {
    showPriceTag(v.getTag().toString());
}

add method showPriceTag() :

public void showPriceTag(String type){
    switch (type)
        {
            case "Chicken":
                //set the price tag data ...
                break;
            case "soap":
                //set the price tag data ...
                break;
            case "Fish":
                //set the price tag data ...
                break;
            default:
                //set the default price tag data ...
                break;
        }
}
