我试图将Facebook作为登录集成在我的导航抽屉应用程序中，当我点击Facebook按钮时，我可以登录但登录后该应用程序不会显示姓名，电子邮件和图片。< / p>
我已经尝试了不同的方法来获取姓名，电子邮件和图片，但它不起作用。其中一种方法是将Profile profileDefault = Profile.getCurrentProfile()放入＆＃34; On Sucess＆＃34;然后是profileDefault.getFirstName（），但是当我运行应用程序并在登录后，应用程序停止。
当我使用getFaceBookProfileDetails功能时，我可以登录，然后应用程序继续运行，但不会显示姓名，电子邮件和图片。
这是主要活动

创建一个manageCallBackOfFacebook()方法或直接在您的活动中添加回调代码。在你的活动课上处理你的facebook回调。
public class LoginActivity extends AppCompatActivity
{
private CallbackManager callbackManager;
private AccessTokenTracker accessTokenTracker;
private ProfileTracker profileTracker;
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
//initialize facebook Sdk
FacebookSdk.sdkInitialize(getApplicationContext());
manageCallBackOfFacebook();
callbackManager = CallbackManager.Factory.create();
setContentView();
...
}
private void manageCallBackOfFacebook()
{
try
{
callbackManager = CallbackManager.Factory.create();
accessTokenTracker = new AccessTokenTracker() {
@Override
protected void onCurrentAccessTokenChanged(AccessToken oldToken, AccessToken newToken) {
}
};
profileTracker = new ProfileTracker()
{
@Override
protected void onCurrentProfileChanged(Profile oldProfile, Profile newProfile)
{
if (newProfile != null)
{
Log.i(TAG +" getName ", newProfile.getName());""+newProfile.getLinkUri());
Log.i(TAG +" getProfilePictureUri", ""+newProfile.getProfilePictureUri(200, 150));
}
}
};
accessTokenTracker.startTracking();
profileTracker.startTracking();
}catch (Exception e){
e.printStackTrace();
}
}
}

尝试此更改..
声明
Profile profile;
private ProfileTracker mProfileTracker;
在你的onCreate（）
中 FacebookSdk.sdkInitialize(getApplicationContext());
callbackManager = CallbackManager.Factory.create();
updateWithToken(AccessToken.getCurrentAccessToken());
accessTokenTracker = new AccessTokenTracker() {
@Override
protected void onCurrentAccessTokenChanged(AccessToken oldToken, AccessToken newToken) {
updateWithToken(newToken);
}
};
accessTokenTracker.startTracking();
loginButton = (LoginButton) findViewById(R.id.login_button);
loginButton.setReadPermissions(Arrays.asList(
"public_profile", "email", "user_friends"));
loginButton.registerCallback(callbackManager, callback);
private void updateWithToken(AccessToken currentAccessToken) {
if (currentAccessToken != null) {
//User logged In--do your stuff
//log out user first
LoginManager.getInstance().logOut();
} else {
//user not logged in
}
}
同样在你的回调方法中 - 将此添加到活动
private FacebookCallback<LoginResult> callback = new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
try {
if (Profile.getCurrentProfile() == null) {
mProfileTracker = new ProfileTracker() {
@Override
protected void onCurrentProfileChanged(Profile profile_old, Profile profile_new) {
// profile2 is the new profile
profile = profile_new;
mProfileTracker.stopTracking();
}
};
mProfileTracker.startTracking();
} else {
profile = Profile.getCurrentProfile();
Log.v("facebook - profile", profile.getFirstName());
}
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object, GraphResponse response) {
Log.v("FACEBOOK LOGIN", response.toString());
// Application code
try {
fb_id = object.getString("id");
fb_name = object.getString("name");
profilePicUrl = "https://graph.facebook.com/" + fb_id + "/picture?width=200&height=200";
fb_email = object.getString("email");
} catch (JSONException e) {
e.printStackTrace();
}
//show facebook data in your activity
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,picture.type(small)");
request.setParameters(parameters);
request.executeAsync();
} catch (Exception e) {
Log.d("ERROR", e.toString());
}
}
@Override
public void onCancel() {
}
@Override
public void onError(FacebookException e) {
Log.d("FACEBOOK ERRROR", e.toString());
}
};
