cannot be resolved or is not a field
<p>i would like to ask how can i solve this problem ..</p>

<pre><code>public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    textOut =(TextView) findViewById(R.id.tvGetInput);
    getInput = (EditText) findViewById(R.id.etInput);
    Button ok = (Button) findViewById (R.id.bOk);
    ok.setOnClickListener(new View.OnClickListener() {
</code></pre>

<p>(the tvGetInput, etInput ,bOk has the error)
it says "cannot be resolve or is not a field" </p>
