Question

I’m stuck in something that I’m sure rather easy

I have a field in the database that I stored the image name in it, ex ‘images/ex1.png’

how can I read this into an imageView?? I tried some code in there but can’t get it to work

a good example is highly

Answer 1

You cannot set the image file directly as the resource for your ImageView (that only takes the resource ID).
Instead you will have to use a BitmapFactory to decode it and then use setImageBitmap

EDIT :

Your problem is that there is no way for you to map the name of the image file with the resource ID in the code. The easier way is probably for you to put together a map table.
First put your image files in the drawable folder (res/drawable/ex1.png…) and then, do something like this in your code :

Map map = new HashMap();

// Add key/value pairs to the map
map.put("images/ex1.png", new Integer(R.drawable.ex1));
map.put("images/ex2.png", new Integer(R.drawable.ex2));
// do that for all the images....

String image_name = // query to your database
ImageView the_image_to_change = // findViewById(...)
if (map.containsKey(image_name)) {
    the_image_to_change.setImageResource((Integer)(map.get(image_name)).intValue()); // not sure so much is necessary...
}
