title: Android cursor get column index using string
body: <p>When I do <code>cursor.getColumnIndex(Database._F_A3)</code> this works as expected.</p>
  
  <p>But if I do this</p>
  
  <pre><code>String dbColumn = "Database._F_A3";
  cursor.getColumnIndex(dbColumn );
  </code></pre>
  
  <p>it gives error.</p>
  
  <p>I believe that this is because <code>getColumnIndex()</code> manages whatever is inside the parenthesis as the string to search in the columns.</p>
  
  <p>Is there any way to do what I want?</p>
