Android-> Facebook登录没有对话框？

Question

I've been following a tutorial from Using Facebook SDK in Android development, Part 1 and Using Facebook SDK in Android development, Part 2 to create a Facebook login. But there, once I press the login-button, a standard login-dialog pops out... Yet, I want it to login with already set credentials, without that dialog, such as a login function that takes in "email" and "password" and returns, say, the user's screen name.

What do you think would be the best way to do that?

I searched the web long and hard and everywhere it says that you can't get rid of the standard login dialog, BUT if we look at the Messenger application, Belgium, man!, it does have a custom login screen! How did they do that? :)

Answer 1

It is better for you to follow the official Facebook's instructions because Facebook changes the API all the time, so even if some post on the Internet had really good tutorials or guides... they get "deprecated" really fast.

The updated information is always here:

• General information

• Android tutorial

You can get a working example at Facebook SDK for Android (GitHub).

I've followed those instructions, and I achieved signup and you do not need to login again (you'll need to re-login only if the token you obtained at signup is not valid anymore or your user deliberately unlinked your application from Facebook).
