In my app I'm loading a webview. The website I'm loading in this webview, has a menu button, but I don't want to display this. So I wrote the code below. However, this isn't working and I don't know why...
{
@Override
public void onPageFinished(WebView view, String url)
{
// when a page has finished loading dismiss any progress dialog
if (progressDialog != null && progressDialog.isShowing())
{
progressDialog.dismiss();
String javascript="javascript: document.getElementById('menu-toggle').css('display','none');";
myWebView.loadUrl(javascript);
}
}
});
UPDATE: Here's the complete java file that still isn't working, I just can't seem to find what's going wrong:
