Note that you said "I'm not sure about the nature of the integer it
wants."
It wants a resource id. Resource ids are what you get when you refer
to a R.drawable.xxx symbol. The most straight-forward way to handle
your situation is as Kantesh suggested -- construct an int array of
the resource ids you wish to select from. Or, if you will likely only
ever refer to one or two of a large set of options, use a switch
statement to select between options:
int the resourceId;
switch(someVariable) {
case someConst1:
theResourceId = R.drawable.Team1;
break;
case someConst2;
theResourceId = R.drawable.Team2;
break;
.....
}
Drawable theDrawable = myResources.getDrawable(theResourceId);
You can also use the Resources.getIdentifier method to convert the
string name of a resource to its resource id, but, as Kostya stated,
that's less efficient in most circumstances. However, it might be
more convenient if what you have coming in is a string that exactly
corresponds to the drawable name you want, or some portion thereof:
String someFullyQualifiedResourceNameString = drawableNameStringPrefix
+ teamName;
int theResourceId =
myResources.getIdentifier(someFulllyQualifiedResourceNameString, null,
null);
Drawable theDrawable = myResources.getDrawable(theResourceId);
