title: WebView in fragment vertical scroll issue
body: <p>I have a <code>WebView</code> in a Fragment. Sometimes when I scroll down, the view goes up and vice versa. 
  My code to load WebView is:</p>
  
  <pre><code>webView = (WebView)v.findViewById(R.id.webView);
  webView.getSettings().setJavaScriptEnabled(true);
  webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
  webView.getSettings().setDomStorageEnabled(true);
  
  
  webView.setWebChromeClient(new WebChromeClient(){
  
      public void onProgressChanged(WebView view, int progress) {
          getActivity().setTitle("Loading...");
          getActivity().setProgress(progress * 100);
          if(progress == 100)
             getActivity().setTitle("2Mummy");
          }
  });
  
  webView.loadUrl("http://my_url_here");
  
  webView.setOnKeyListener(new View.OnKeyListener(){
  
      public boolean onKey(View v, int keyCode, KeyEvent event) {
          if (keyCode == KeyEvent.KEYCODE_BACK
                  &amp;&amp; event.getAction() == MotionEvent.ACTION_UP
                  &amp;&amp; webView.canGoBack()) {
             handler.sendEmptyMessage(1);
             return true;
          }
          return false;
       }
  });
  
  webView.setWebViewClient(new WebViewClient() {
      public boolean shouldOverrideUrlLoading(WebView view, String url){
          view.loadUrl(url);
          if ((webView.canGoBack()) || (url!=url)){
  
          }
          else{
  
          }
          return false; 
      }
  
      @Override
      public void onPageStarted(WebView view, String url, Bitmap favicon){
  
      }
  
      @Override
      public void onPageFinished(WebView view, String url){
           webView.setVisibility(View.VISIBLE);
      }
  
  });
  webView.scrollTo(0,webView.getContentHeight());
  </code></pre>
  
  <p>And my fragment xml is</p>
  
  <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
      xmlns:tools="http://schemas.android.com/tools"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:id="@+id/categoriesfrag"
      tools:context="com.quadcircles.tomummy.Fragment.Categories"&gt;
  
  &lt;WebView
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:id="@+id/webView"/&gt;
  </code></pre>
  
  <p></p>
  
  <p>When I load the site from my phone, it scrolls perfectly, issue comes up when I load the same site in <code>WebView</code>.
  Your suggestions are appreciated</p>
