Question

This might be a problem that I might overlook again but if you could help me solve it, I will be very thankful.
Using this code to get images from drawable and sending it to Imageview.setImageResource (in which my Imageview is inside a gridview); everything works well

private   Integer[] imageIDs = {
            //R.drawable.image1,
            R.drawable.image2,
            R.drawable.image3,
            R.drawable.image4,
            R.drawable.image5,
            R.drawable.image6,
            R.drawable.Image7,
};

//Here is my another code to call imageIDs as ImageResource
ImageView iv = (ImageView)v.findViewById(R.id.grid_item_picture);
iv.setImageResource(imageIDs[position]);
//position is a default value of gridview starting from 0 

Now what I trying to accomplish is to delete that array and convert it to ArrayList simply because need these inside data to be dynamic. And so I’ve created this new code

ArrayList<String> array_image = new ArrayList<String>();
        array_image.add("R.drawable.image6");
        array_image.add("R.drawable.image1");

and set the ImageView ImageResource to this code

iv.setImageResource(array_image .get(position));

I am getting an error saying:

The method setImageResource(int) in the type ImageView is not applicable for the arguments (Object)
Can you help me fix/figure it out?

Answer 1

You are defining an ArrayList for Strings. However you need integers as resource identifiers.

Do it instead like this;

ArrayList<Integer> array_image = new ArrayList<Integer>();
array_image.add(R.drawable.image6);
array_image.add(R.drawable.image1);
