Android Facebook 4.0 SDK 如何获取电子邮件、出生日期和用户性别

我使用以下代码。我想要用户的出生日期，电子邮件和性别。请帮帮我。如何检索这些数据？

这是我在碎片里的 onViewCreated()。

@Override
public void onViewCreated(View view, Bundle savedInstanceState) {


// Setup TextView.
mTextDetails = (TextView) view.findViewById(R.id.text_details);


// Set up Login Button.
LoginButton mButtonLogin = (LoginButton) view.findViewById(R.id.login_button);
// setFragment only if you are using it inside a Fragment.
mButtonLogin.setFragment(this);
mButtonLogin.setReadPermissions("user_friends");
mButtonLogin.setReadPermissions("public_profile");
mButtonLogin.setReadPermissions("email");
mButtonLogin.setReadPermissions("user_birthday");


// Register a callback method when Login Button is Clicked.
mButtonLogin.registerCallback(mCallbackManager, mFacebookCallback);


}

这是我的回调方法。

private FacebookCallback<LoginResult> mFacebookCallback = new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
Log.d("Shreks Fragment", "onSuccess");




Profile profile = Profile.getCurrentProfile();
Log.d("Shreks Fragment onSuccess", "" +profile);


// Get User Name
mTextDetails.setText(profile.getName() + "");


}




@Override
public void onCancel() {
Log.d("Shreks Fragmnt", "onCancel");
}


@Override
public void onError(FacebookException e) {
Log.d("Shreks Fragment", "onError " + e);
}
};

您可以使用 GraphRequest 类发出对 Facebook Graph API 的调用以获取用户信息。有关更多信息，请参见 https://developers.facebook.com/docs/android/graph。

在 onSuccess()中无法获得 Profile，需要实现 ProfileTracker并注册回调

mProfileTracker = new ProfileTracker() {
@Override
protected void onCurrentProfileChanged(Profile oldProfile, Profile newProfile) {
// Fetch user details from New Profile
}
};

同样不要忘记处理配置文件跟踪程序的开始和结束

现在您将拥有一个用于获取 AccessToken 的配置文件(解决了空配置文件的问题)。你只需要使用“ https://developers.facebook.com/docs/android/graph#userdata”来获得任何数据。

这不是设置权限的正确方法，因为您正在用每个方法调用覆盖它们。

取而代之的是:

mButtonLogin.setReadPermissions("user_friends");
mButtonLogin.setReadPermissions("public_profile");
mButtonLogin.setReadPermissions("email");
mButtonLogin.setReadPermissions("user_birthday");

如下所示，方法 setReadPermissions()接受 ArrayList:

loginButton.setReadPermissions(Arrays.asList(
"public_profile", "email", "user_birthday", "user_friends"));

还有如何查询额外的数据 GraphRequest:

private LoginButton loginButton;
private CallbackManager callbackManager;


@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);


loginButton = (LoginButton) findViewById(R.id.login_button);


loginButton.setReadPermissions(Arrays.asList(
"public_profile", "email", "user_birthday", "user_friends"));


callbackManager = CallbackManager.Factory.create();


// Callback registration
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
// App code
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject object, GraphResponse response) {
Log.v("LoginActivity", response.toString());


// Application code
String email = object.getString("email");
String birthday = object.getString("birthday"); // 01/31/1980 format
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender,birthday");
request.setParameters(parameters);
request.executeAsync();




}


@Override
public void onCancel() {
// App code
Log.v("LoginActivity", "cancel");
}


@Override
public void onError(FacebookException exception) {
// App code
Log.v("LoginActivity", exception.getCause().toString());
}
});
}

编辑:

一个可能的问题是 Facebook 假设你的电子邮件是无效的。要测试它，使用 图形 API 浏览器并尝试获得它。如果即使在那里你不能得到你的电子邮件，改变它在您的配置文件设置，并再次尝试。这种方法为一些评论我的答案的开发人员解决了这个问题。

使用 Profile 类的 FB 静态方法 getCurrentProfile ()检索这些信息。

 Profile profile = Profile.getCurrentProfile();
String firstName = profile.getFirstName());
System.out.println(profile.getProfilePictureUri(20,20));
System.out.println(profile.getLinkUri());

使用此代码片段获取所有配置文件信息

private FacebookCallback<LoginResult> callback = new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
AccessToken accessToken = loginResult.getAccessToken();
Profile profile = Profile.getCurrentProfile();


// Facebook Email address
GraphRequest request = GraphRequest.newMeRequest(
loginResult.getAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
Log.v("LoginActivity Response ", response.toString());


try {
Name = object.getString("name");


FEmail = object.getString("email");
Log.v("Email = ", " " + FEmail);
Toast.makeText(getApplicationContext(), "Name " + Name, Toast.LENGTH_LONG).show();




} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender, birthday");
request.setParameters(parameters);
request.executeAsync();




}


@Override
public void onCancel() {
LoginManager.getInstance().logOut();


}


@Override
public void onError(FacebookException e) {


}
};

登入后

private void getFbInfo() {
GraphRequest request = GraphRequest.newMeRequest(
AccessToken.getCurrentAccessToken(),
new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(
JSONObject object,
GraphResponse response) {
try {
Log.d(LOG_TAG, "fb json object: " + object);
Log.d(LOG_TAG, "fb graph response: " + response);


String id = object.getString("id");
String first_name = object.getString("first_name");
String last_name = object.getString("last_name");
String gender = object.getString("gender");
String birthday = object.getString("birthday");
String image_url = "http://graph.facebook.com/" + id + "/picture?type=large";


String email;
if (object.has("email")) {
email = object.getString("email");
}


} catch (JSONException e) {
e.printStackTrace();
}
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,first_name,last_name,email,gender,birthday"); // id,first_name,last_name,email,gender,birthday,cover,picture.type(large)
request.setParameters(parameters);

这是为我工作，希望帮助有人(使用我自己的按钮不 FB 登录按钮)

CallbackManager callbackManager;


@Override

super.onCreate(savedInstanceState);
FacebookSdk.sdkInitialize(getApplicationContext());
setContentView(R.layout.activity_sign_in_user);

try {
Log.i("RESAULTS : ", object.getString("email"));
}catch (Exception e){


}
}

Bundle parameters = new Bundle();
parameters.putString("fields", "email");
request.setParameters(parameters);
request.executeAsync();


}


@Override
public void onCancel() {


}


@Override

以下是查找电子邮件 ID、名称和配置文件 URL 等的代码

    private CallbackManager callbackManager;


protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_sign_in);
//TODO on click of fb custom button call handleFBLogin()
callbackManager = CallbackManager.Factory.create();
}


private void handleFBLogin() {
AccessToken accessToken = AccessToken.getCurrentAccessToken();
boolean isLoggedIn = accessToken != null && !accessToken.isExpired();


if (isLoggedIn && Store.isUserExists(ActivitySignIn.this)) {
goToHome();
return;
}


LoginManager.getInstance().logInWithReadPermissions(ActivitySignIn.this, Arrays.asList("public_profile", "email"));
LoginManager.getInstance().registerCallback(callbackManager,
new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(final LoginResult loginResult) {
runOnUiThread(new Runnable() {
@Override
public void run() {
setFacebookData(loginResult);
}
});
}


@Override
public void onCancel() {
Toast.makeText(ActivitySignIn.this, "CANCELED", Toast.LENGTH_SHORT).show();
}


@Override
public void onError(FacebookException exception) {
Toast.makeText(ActivitySignIn.this, "ERROR" + exception.toString(), Toast.LENGTH_SHORT).show();
}
});
}


private void setFacebookData(final LoginResult loginResult) {

}


//TODO put your code here

在点击按钮上添加这一行

SetReadPermission (Arrays.asList ( “ public _ profile”、“ email”、“ user _ life”、“ user _ friends”) ;

这里有一个可行的解决方案(2019年) : 将此代码放入您的登录逻辑中;

 GraphRequest request = GraphRequest.newMeRequest(loginResult.getAccessToken(), new GraphRequest.GraphJSONObjectCallback() {
@Override
public void onCompleted(JSONObject json, GraphResponse response) {
// Application code
if (response.getError() != null) {
System.out.println("ERROR");
} else {
System.out.println("Success");
String jsonresult = String.valueOf(json);
System.out.println("JSON Result" + jsonresult);


String fbUserId = json.optString("id");
String fbUserFirstName = json.optString("name");
String fbUserEmail = json.optString("email");
//String fbUserProfilePics = "http://graph.facebook.com/" + fbUserId + "/picture?type=large";
Log.d("SignUpActivity", "Email: " + fbUserEmail + "\nName: " + fbUserFirstName + "\nID: " + fbUserId);
}
Log.d("SignUpActivity", response.toString());
}
});
Bundle parameters = new Bundle();
parameters.putString("fields", "id,name,email,gender, birthday");
request.setParameters(parameters);
request.executeAsync();
}


@Override
public void onCancel() {
setResult(RESULT_CANCELED);
Toast.makeText(SignUpActivity.this, "Login Attempt Cancelled", Toast.LENGTH_SHORT).show();
}


@Override
public void onError(FacebookException error) {
Toast.makeText(SignUpActivity.this, "An Error Occurred", Toast.LENGTH_LONG).show();
error.printStackTrace();
}
});
