title: webview inside an alertBuilder, keyboard doesnt pop up
body: <p>i wrote a function that opens a webView inside of a dialog,
  the problem is that the keyboard doesnt pop up when i click a textArea
  i tried all the solutions in <a href="https://stackoverflow.com/questions/3460915/webview-textarea-doesnt-pop-up-the-keyboard">this</a> thread to no avail</p>
  
  <p>this code is function in a android.support.v4.app.Fragment</p>
  
  <pre><code>    public void openWebView() {
          AlertDialog.Builder alertBuilder = new AlertDialog.Builder(this.getActivity());
          WebView webView = new WebView(this.getActivity());
          webView.loadUrl("http://www.google.com");
          webView.setWebViewClient(new WebViewClient() {
              @Override
              public boolean shouldOverrideUrlLoading(WebView view, String url) {
                  view.loadUrl(url);
  
                  return true;
              }
          });
          alertBuilder.setView(webView);
          webView.getSettings().setJavaScriptEnabled(true);
          alertBuilder.show();
  }
  </code></pre>
  
  <p>this is the log when i press the text area a few times:</p>
