setScrollX method doesn't work same with different screen sizes

Question

I found that setScrollX doesn't work in the same way in different screen sizes. But the scale method setScaleX works the same in different devices (I mean it shows the same scaled image). How can I get the same result from setScrollX in different android phones or tablets?

I used this methods for an ImageView and actually I want to zoom to an ImageView and then scroll on it.

ImageView mainImage = findViewById(R.id.mainImage);
mainImage.setImageResource(R.drawable.mainImg);
mainImage.setScaleX(6);
mainImage.setScaleY(6);
mainImage.setScrollX(200);
mainImage.setScrollY(200);
