title: Textbox hidden below keyboard in Android XWalkView or WebView
body: <p><strong>Edit:</strong> this also adjust to webview!</p>
  
  <p>I use XWalkView of corsswalk in my android app. In the XWalkView there are many inputs in it. When I input something for the input at the bottom , the soft keyboard covers it.
  I  use <code>android:windowSoftInputMode="adjustPan"</code> in the activity, </p>
  
  <p>or in addition add <code>android:isScrollContainer="true"</code> in the xwalkview, </p>
  
  <p>But neither works.</p>
  
  <p>And help will be appreciated.</p>
