ImageView img = (ImageView) findViewById(R.id.imageview);
img.setImageURI(Uri.parse(path));

you can get the bitmap from the path like that

 Bitmap bmp = BitmapFactory.decodeFile(img_path );
    img.setImageBitmap(bmp);

or can try this one

String path= "@drawable/myresource.png";
int imageResource = getResources().getIdentifier(path, null, getPackageName());
Drawable res = getResources().getDrawable(imageResource);
img.setImageDrawable(res);

Try this:

ImageView img = (ImageView) findViewById(R.id.imageview);
InputStream inputStream = getClass().getResourceAsStream(path);
img.setImageDrawable(Drawable.createFromStream(inputStream, ""));
