Android AsyncTask，警告：“为varargs参数创建未经检查的泛型数组”

Question

How do I get rid of the warning? The code I'm using:

private void tryNew(List<Something> somethingList){
    new AsyncTask<List<Something>,Void,Void>(){
        @Override
        protected Void doInBackground(List<Something> [] somethingList) {
            //some code
            return null;
        }
    }.execute(somethingList);
}

Answer 1

I was with this same warning and could remove it just by using the object I use on the parameter of the execute method, without generics. Sorry my bad english, but I'll try to explain better.

Instead create my AsyncTask this way:

new AsyncTask<MyObject<GenericsInsideGenerics>, Void, Void>...

I've created this way:

new AsyncTask<MyObject, Void, Void>...

And it works fine!

If you want to remove the warning message then you have to use the designated varargs of AsyncTask.

private void tryNew(List<Something> somethingList){
    new AsyncTask<Something,Void,Void>(){
        @Override
        protected Void doInBackground(Something.. s) {
            //some code
            return null;
        }
    }.execute(somethingObject1, somethingObject2, somethingObject3);
}
