[Search widget for Android] How to hide the close button in the default search mode?

Question

I implemented Android SearchViewin ActionBar. When it SearchViewreceives focus, the close button [x] appears on the right. I looked at other native Android apps such as Contacts and Gmail. The close button is not displayed when it SearchViewreceives focus.

How to configure my SearchViewto behave like that?
