从AsyncTask类调用主类的非静态方法

Question

我需要从AsyncTask调用一个非静态方法

必须在onPostExecute中调用此方法

我用过：

Main.mymethod();

Cannot make a static reference to the non-static method mymethod() from the type Main

编辑：我尝试过：

    protected void onPostExecute(String result) {
         new Main().mymethod();
    }

Answer 1

mymethod(); call this method simply
mymethod(); you can also pass parameters to it if you have defined parameterized method like mymethod(someObj, someVariable);
