Get drawable by string

Issue

I parse image name by json, and now for displaying I would have to get the drawable id by the image name so I can do this:

background.setBackgroundResource(R.drawable.eventimage1);

When I get the image name the format is like this:

image_ev1.png

Solution

Use this function to get a drawable when you have the image name. Note that the image name does not include the file extension.

public static Drawable GetImage(Context c, String ImageName) {
        return c.getResources().getDrawable(c.getResources().getIdentifier(ImageName, "drawable", c.getPackageName()));
}

then just use setBackgroundDrawable method.

If you only want the ID, leave out the getDrawable part i.e.

return c.getResources().getIdentifier(ImageName, "drawable", c.getPackageName());
