Implement login facebook for android
<p>I am creating an app for android that uses the facebook login. My question is: is to create a screen with fields username and password to lgin on facebook? because I do not want to use one's own facebook small screen that is called when you click the button to login.</p>

<p>Explaining ...
I want on my main screen I have a button "Login with Facebook" and when the user clicks on this button will open two fields (username and password) and login button to confirm.</p>

<p>Thank you!</p>
