title: click gridview item and editext gets focus
body: <p>I have displayed a gridview whose items are a textview and edittext.Now ,how to  achieve function that I click the gridview item and the edittext get the focus?</p>
  
  <pre><code>gridview.setOnItemClickListener(new OnItemClickListener() {
  
          @Override
          public void onItemClick(AdapterView&lt;?&gt; parent, View view,
                  int position, long id) {
  </code></pre>
  
  <p>how to override this function?
  I try that before:</p>
  
  <pre><code>((EditText)gridview.getChildAt(position).findViewById(R.id.grid_edittext)).requestFocus();
  </code></pre>
  
  <p>and also:</p>
  
  <pre><code>((ViewGroup)gridview.getChildAt(position)).getChildAt(1).requestFocus();
  </code></pre>
  
  <p>There adds a System.out.printlen("hello");
  in onitemclick function,but it doesn't show up in logcat.</p>
  
  <p>Is there any samples??</p>
