Re: [android-developers] Java Generics question (Using AsyncTask)...
Thanks for the response...
I've just saw it today...
this is my class declaration public class AsyncRequestT extends
AsyncTaskObject, Void, AsyncResponseT {
using getTypeParameters
TypeVariable?[] types = getClass().getTypeParameters();
types[0].getBounds()[0] is a class java.lang.Object
The only way I got it working is when instantiating my class
AsyncRequestResponseDTO asyncRequest = new
AsyncRequestResponseDTO(mContext, asyncResponseListener){};
Using an empty anonymous inner class

(parameterized.getActualTypeArguments()[0] is a String type).
That's the way getGenericSuperclass() is supposed to work. Use
getTypeParameters() to get the generic variables of the current class.

[android-developers] Java Generics question (Using AsyncTask)...
Hi,
I'm having some troubles with generics, trying to get the Type of my
Parameterized class???
Let's begin with a working example...
class TestClassT {
Type type;
public TestClass() {
type = getSuperclassTypeParameter(getClass());
}
static Type getSuperclassTypeParameter(Class? subclass) {
Type superclass = subclass.getGenericSuperclass();
if (superclass instanceof Class) {
throw new RuntimeException(Missing type parameter.);
}
ParameterizedType parameterized = (ParameterizedType) superclass;
return parameterized.getActualTypeArguments()[0];
}
}
Whit this code, I can get at runtime, the Type of T (like TestClassString
will return a String type).
My problem is when I have a generic class extending another generic class.
class AsyncRequestT extends AsynTaskString, Void, AsyncResponseT {
Type type;
public AsyncRequest() {
type = getSuperclassTypeParameter(getClass());
}
static Type getSuperclassTypeParameter(Class? subclass);
}
In this case, with getSuperclassTypeParameter() I get the parameterized
types of AsyncTask, and not of my own Class AsyncRequest...
(parameterized.getActualTypeArguments()[0] is a String type).
Anyone has some ideia of how I can get the Type of T of my own Class???
Thanks in advance...
