java - Get input from edittext using an anonymous class, android -


long story short trying make app convert celsius fahrenheit , back. want input edit text can use math, can't figure out, nor can button work right close it. want use internal anonymous class calculations , read in value, again no idea do. have idea start?

here have

package com.example.a4;  import android.os.bundle; import android.app.activity; import android.content.dialoginterface;  import android.content.dialoginterface.onclicklistener; import android.text.editable; import android.text.textwatcher; import android.view.menu; import android.widget.button; import android.widget.edittext;   public class mainactivity extends activity implements textwatcher {  edittext mt=(edittext) findviewbyid(r.id.et1),           mt2=(edittext) findviewbyid(r.id.et2);  button bt = (button) findviewbyid(r.id.btn1);  @override protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.activity_main);     //mt=(edittext) findviewbyid(r.id.et1);    // mt2=(edittext) findviewbyid(r.id.et2); }  onclicklistener oclbtnok = new onclicklistener() {       @override     public void onclick(dialoginterface arg0, int arg1) {         // todo auto-generated method stub      }   };    /*     buttonexit.setonclicklistener(        new view.onclicklistener() {            public void onclick(view v) {                system.exit(0);         }     } );*/   @override public void aftertextchanged(editable s) {     // todo auto-generated method stub     int c = integer.parseint(s.tostring());      ftoc(c);  }  @override public void beforetextchanged(charsequence s, int start, int count,         int after) {     // todo auto-generated method stub  }  @override public void ontextchanged(charsequence s, int start, int before, int count) {     // todo auto-generated method stub  }    void ftoc(int c){   int f = ((9/5)*c) + 32;    mt2.settext(f);  }     /*   @override   public boolean oncreateoptionsmenu(menu menu) {     // inflate menu; adds items action bar if present.     getmenuinflater().inflate(r.menu.main, menu);       return true;   }   */     }

you need move mt = (edittext)findviewbyid stuff oncreate. then, if want use anonymous classes, like:

mt.setonclicklistener(new onclicklistener() {      public void onclick(view v) {           ...      } });

also, make sure you're using view.onclicklistener , not dialoginterface.onclicklistener (check imports).

i know integration tests preferred need ran in controller test, i'm testing gem injecting html code in view, xhr can't run in feature spec (if can, please explain me how :) ) so rspec controller tests can assert selector present (with capybara) : response.body.should have_selector('#foobar') has_selector? call all method capybara find selector. what want last child of body , assert id in particular. afaik it's not possible have_selector. what : all('body:first-child').first.id.should == '#foobar' however, capybara dsl, defined (more or less): def all(*args) page.all(*args) end and page empty unless use visit it's integrations specs. how can use capybara all method inside rspec controller test ? i can't test right after googling seems trick def page capybara::node::simple.new(response.body) end source
