java - Cannot make a static reference to a non-static method -

-

this question has answer here:

i have in java code, when try compile code error. happens when try value of text in textview var. cannot understand error because works fine in other method.

why happens , how can fix it?

    public class mainactivity extends activity {          public edittext edittext;         textview textview;           @override         protected void oncreate(bundle savedinstancestate) {             super.oncreate(savedinstancestate);             setcontentview(r.layout.activity_main);             toast.maketext(mainactivity.this, "oncreate", toast.length_long).show();              //setupmessagebutton();              edittext = (edittext) findviewbyid(r.id.edittext1);             textview = (textview)findviewbyid(r.id.tvisconnected);           }          public void btndisplaymessage(view view){              //here works fine             string missatge = edittext.gettext().tostring();          }      public static string post(string url){         inputstream inputstream = null;         string result = "";         //here crashes         string missatge = "red"//edittext.gettext().tostring(); gives error         string usuario = "foo";  ............

why?

edit: downvote question, yes, searched similar questions , i've tried static method...then don't crash content of var null , don't work @ all.

you can not access variable non static static method...

solutions:

  1. make edittext static
  2. its not logical 1 static method access variable non static, should change logic there!

greetings :)...
