Dynamic image with variable as a name

Question

I am trying to display an image when i have variable from array (arr[r1]) which matches the name of the picture. I tried using this but it didnt work:

ImageView imageView = (ImageView)findViewById(R.id.imageView);
imageView.setImageDrawable(getResources().getDrawable(getResources().getIdentifier("drawable/"+arr[r1], "drawable", getPackageName())));

Any idea what i am doing wrong?

imageView.setImageDrawable(getResources().getDrawable(getResources().getIdentifier("@drawable/"+arr[r1], "drawable", getPackageName()))); — Kirit Vaghela

String filePath = getActivity().getFileStreamPath("myimage.png").getAbsolutePath();

img.setImageDrawable(Drawable.createFromPath(filePath));

Replace this

imageView.setImageDrawable(getResources().getDrawable(getResources().getIdentifier("drawable/"+arr[r1], "drawable", getPackageName())));

with

imageView.setImageDrawable(getResources().getDrawable(getResources().getIdentifier(arr[r1], "drawable", getPackageName())));

Hope it works for you.

this work fine for me

imageView.setImageDrawable(getResources().getDrawable(getResources().getIdentifier("@drawable/ic_launcher", "drawable", getPackageName())));

for your case use this

imageView.setImageDrawable(getResources().getDrawable(getResources().getIdentifier("@drawable/"+arr[r1], "drawable", getPackageName())));
