How to define a large group of imageViews?

Question

I have 64 image view in android studio and I don't want to define them one by one like this:

ImageView iv11 = findViewById(R.id.iv11);

id of ImageViews start by iv11 (the first number is row and second col) and end with iv88 is there any way to define all of them together?

You should populate your views with an adapter. Since it sounds like you need the images to be displayed in a grid, you could use GridView with an adapter.

There are lot of tutorials that would guide you to do this; eg: you can look at this for a start.

Hope this helps.

Construct your ImageView id by for loops and call getResources().getIdentifier()

for (int col = 0 ; col < 8; ++col) {
    for (int row = 0 ; row < 8; ++row) {
        String idStr = "iv" + String.valueOf(row) + String.valueOf(col);
        @IdRes int id = context.getResources().getIdentifier(idStr, "id", context.getPackageName());

        ImageView imgView = findViewById(id);
        // Do something with your image
    }
}

Anyway, with that much ImageView on screen, it should be managed by an adapter like ListView, RecyclerView...
