Android, getting resource ID from string?

Question

I need to pass a resource ID to a method in one of my classes. It needs to use both the id that the reference points to and also it needs the string. How should I best achie

Answer 1

In your res/layout/my_image_layout.xml

To grab that ImageView by its @+id value, inside your java code do this:

String row = "0";
String column= "7";
String tileID = "row_" + (row) + "_col_" + (column);
ImageView image = (ImageView) activity.findViewById(activity.getResources()
                .getIdentifier(tileID, "id", activity.getPackageName()));

/*Bottom code changes that ImageView to a different image. "blank" (R.mipmap.blank) is the name of an image I have in my drawable folder. */
image.setImageResource(R.mipmap.blank);
