Android - How can I load an image to a ImageView?

I want to make a simple image viewing program, that just takes the images from a certain folder, and loads them from it.

I did some coding with less thinking, so I did stumble upon this:

Button btn = (Button) this.findViewById(R.id.buttonNext);
        btn.setOnClickListener(new OnClickListener() {

   public void onClick(View v) 
   {
    View rootView = (View)v.getParent();
    ImageView im = (ImageView) rootView.findViewById(R.id.imageView);
    //and here comes the problem...


   }

I have all my images from the folder loaded and have a collection, containg of all their absolute paths. Now, I want my imageView to switch its picture src with one from my collection. But how can I do that ?

Collections Filled with Absolute Paths? I'd recommend you create an int Array of their Id's (R.drawable.image01) then use the setImageResource(arr[3]) to set it...

But if you have to use the paths...then this page might help...

Use Bitmaps. After reading the file from the absolute paths, convert to Bitmaps (see BitmapFactory) and apply the Bitmap to the ImageView.
