Next button in keyboard not coming while filing HTML5 form in Android

I have a simple HTML5 form, opened in Android webview. But while f开发者_Go百科iling the input textboxes, the keyboard is coming but, the next button ( ->| ) is not coming.

What can be the issue ?

---

Got few points, that prevent the 'Next' button to come

• Form having
• If the page is in 'multiple pages in Single page'
• having blank <script> or <style>
