title: field constant and @override
body: <p>Im trying to elminate all errors for an android app developed using Eclipse..</p>
  
  <pre><code>     "run_buton = (ToggleButton) findViewById(R.id.tbtn_runtoggle);
       run_buton.setOnClickListener(this);
       rb1 = (RadioButton)findViewById(R.id.rbtn_ch1);
       rb2 = (RadioButton)findViewById(R.id.rbtn_ch2);"
  </code></pre>
  
  <p>These are part of my code in the .java file in the src file...however there are errors..eclipse says that tbtn_runtoggle,rbtn_ch1, rbtn.ch2 cannot be resolved or it is not a field...so i use the quick fix and make them into a field...- -however it's still not work..i dont know what is happenening...and im just responsible for eliminating all errors...- -the codes are not written by myself..</p>
  
  <p>and may I ask what is the use of @override..
  it tells me "public void  onClick(View v){" must override a superclass method..so it suggests me to remove @override...but still gets error...why..???</p>
