FaceBook 文档代码
1.Add the Facebook Login Button
2.Register a Callback
callbackManager = CallbackManager.Factory.create();
If you are adding the button to a Fragment you must also update your activity to use your fragment. You can customize the properties of Login button and register a callback in your onCreate() or onCreateView() method. Properties you can customize includes LoginBehavior, DefaultAudience, ToolTipPopup.Style and permissions on the LoginButton. For example:
private static final String EMAIL = "email";
loginButton = (LoginButton) findViewById(R.id.login_button);
loginButton.setReadPermissions(Arrays.asList(EMAIL));
// If you are using in a fragment, call loginButton.setFragment(this);
// Callback registration
loginButton.registerCallback(callbackManager, new FacebookCallback() {
@Override
public void onSuccess(LoginResult loginResult) {
// App code
}
@Override
public void onCancel() {
// App code
}
@Override
public void onError(FacebookException exception) {
// App code
}
});
To respond to a login result, you need to register a callback with either LoginManager or LoginButton. If you register the callback with LoginButton, don't need to register the callback on Login manager.
You add the LoginManager callback to your activity or fragment's onCreate() method:
callbackManager = CallbackManager.Factory.create();
LoginManager.getInstance().registerCallback(callbackManager,
new FacebookCallback() {
@Override
public void onSuccess(LoginResult loginResult) {
// App code
}
@Override
public void onCancel() {
// App code
}
@Override
public void onError(FacebookException exception) {
// App code
}
});
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
callbackManager.onActivityResult(requestCode, resultCode, data);
super.onActivityResult(requestCode, resultCode, data);
}
Check Login Status
Your app can only have one person at a time logged in, and LoginManager sets the current AccessToken and Profile for that person. The FacebookSDK saves this data in shared preferences and sets at the beginning of the session. You can see if a person is already logged in by checking AccessToken.getCurrentAccessToken() and Profile.getCurrentProfile().
You can load AccessToken.getCurrentAccessToken with the SDK from cache or from an app book mark when your app launches from a cold start. You should check its validity in your Activity's onCreate method:
AccessToken accessToken = AccessToken.getCurrentAccessToken();
boolean isLoggedIn = accessToken != null && !accessToken.isExpired();
Then you can later perform the actual login, such as in a custom button's OnClickListener:
LoginManager.getInstance().logInWithReadPermissions(this, Arrays.asList("public_profile"));
