Use the content of a string for a variable referencing a picture Android/Java

Question

i got this :

String input = "image_to_show"

and in my drawables:

image_to_show.png

i do:

imageView.setImageResource(R.drawable.image_to_show);   

this works and refers to the object in drawables

can i get it to work using the string with the contexts being the same name as the drawables object

Answer 1

First, find resId by name

int resId = getResources().getIdentifier(resName, "drawable", getPackageName());

then use the found resId

imageView.setImageResource(resId);   

Answer 2

You should use Resources getIdentifier method to get the relevant id.

after you get that id, call imageView.setImageResource(R.drawable.image_to_show); as usual
