How to dynamically get R value

Issue

I have to dynamically get some resources from the R file.

For example, let's say I have to dynamically generate ImageView and dynamically get a drawable to put inside it.

I don't know how many ImageView I have to generate; there may be 10, 50 or 100 so I have to do everything dynamically.

My main problem is to get dynamically the drawable from the R file.

Lets say I have this drawable: R.drawable.img1 R.drawable.img2 R.drawable.img3 R.drawable.img4

I should do something like this:

    for(int i = 0; i < 10; i++){
        ImageView iv = new ImageView(this);
        iv.setImageResource(R.drawable.img + i);            
    }

How can I "build" this line of code: R.drawable.img + i

How can I reach my goal?

Solution

At first make sure your image is jpg or png

You can try with this

   for(int i = 0; i < 10; i++)
     {
      ImageView iv = new ImageView(this);
      int imageResource = context.getResources().getIdentifier("@drawable/img "+i.replace(".jpg", ""), null,context.getPackageName());
      iv.setImageResource(imageResource);
       }
