Android - Open resource from @drawable String

Question

I have:

 String uri = "@drawable/myresource.png"; 

How can I load that in ImageView? this.setImageDrawable?

Answer 1

If you really need to work with a string, try something like this:

private void showImage() {     String uri = "drawable/icon";      // int imageResource = R.drawable.icon;     int imageResource = getResources().getIdentifier(uri, null, getPackageName());      ImageView imageView = (ImageView) findViewById(R.id.myImageView);     Drawable image = getResources().getDrawable(imageResource);     imageView.setImageDrawable(image); } 

Else I would recommend you to work with R.* references like this:

int imageResource = R.drawable.icon; Drawable image = getResources().getDrawable(imageResource); 

Answer 2

First, don't do that, as that @drawable syntax is meaningless in Java code. Use int resourceId=R.drawable.myresource.

If for some reason you do wind up a resource name and need the integer ID, use getIdentifier() on the Resources object.
