set different image by getting image's name from out side

Issue

In my Widget i have one ImageView , i will receive a code from out side ,these codes are between 1-40 , from other side i have 40 different images in my drawable folder which i named them the same as their related code. now what I want to do it ,by reading one code from outside, show the image which has the same name in the ImageView. for example if i read the code 33, i want to show the image which named 33 in the ImageVIew.

Solution

put your images in assets folder and you will be able to pick image by name. suppose your text is 33 and your image name is 33.png

AssetManager assetManager = context.getAssets();
String fileName = "33";
Bitmap b = BitmapFactory.decodeStream(assetManager.open(fileName + ".png"));
imageView.setImageBitmap(b);
