你可以轻松地使用SocialAuth。 示例在
下面<强>初始化
初始化SocialAuth适配器对象并创建Facebook按钮。单击该按钮可授权适配器。
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
adapter = new SocialAuthAdapter(new ResponseListener());
facebook_button = (Button)findViewById(R.id.fb_btn);
facebook_button.setBackgroundResource(R.drawable.facebook);
facebook_button.setOnClickListener(new OnClickListener()
{
public void onClick(View v)
{
adapter.authorize(ProviderUI.this, Provider.FACEBOOK);
}
});
}
在ResponseListener中接收身份验证响应并启动调用以获取各种功能。见下面的例子：
更新状态
通过调用adapter.updateStatus（）来共享您的状态，并验证MessageListener中的响应。您可以使用任何语言在Facebook墙上分享您的状态。
private final class ResponseListener implements DialogListener
{
public void onComplete(Bundle values) {
adapter.updateStatus(edit.getText().toString(), new MessageListener());
}
}
// To get status of message after authentication
private final class MessageListener implements SocialAuthListener {
@Override
public void onExecute(Integer t) {
Integer status = t;
if (status.intValue() == 200 || status.intValue() == 201 ||status.intValue() == 204)
Toast.makeText(CustomUI.this, "Message posted",Toast.LENGTH_LONG).show();
else
Toast.makeText(CustomUI.this, "Message not posted",Toast.LENGTH_LONG).show();
}
}
更新故事
通过调用adapter.updateStory（）来共享故事并验证MessageListener中的响应。您需要以下字段来共享故事：消息，标题，链接，图像。
private final class ResponseListener implements DialogListener
{
public void onComplete(Bundle values) {
adapter.updateStory( "Hello SocialAuth Android" , "Google SDK for Android",
"Build great social apps and get more installs.",
"The Facebook SDK for Android makes it easier and faster to develop Facebook integrated
Android apps.", "https://www.facebook.com",
"http://carbonfreepress.gr/images/facebook.png", new MessageListener());
}
}
// To get status of message after authentication
private final class MessageListener implements SocialAuthListener {
@Override
public void onExecute(Integer t) {
Integer status = t;
if (status.intValue() == 200 || status.intValue() == 201 ||status.intValue() == 204)
Toast.makeText(CustomUI.this, "Message posted",Toast.LENGTH_LONG).show();
获取个人资料
通过getUserprofileAsync（）方法获取用户配置文件，并在profileDataListener中接收响应。你可以得到
Facebook的用户个人资料ID，名字，姓氏，电子邮件，性别，国家/地区，语言，位置和个人资料图片网址。
private final class ResponseListener implements DialogListener
{
public void onComplete(Bundle values) {
adapter.getUserProfileAsync(new ProfileDataListener());
}
}
// To receive the profile response after authentication
private final class ProfileDataListener implements SocialAuthListener {
@Override
public void onExecute(Profile t) {
Log.d("Custom-UI", "Receiving Data");
Profile profileMap = t;
Log.d("Custom-UI", "Validate ID = " + profileMap.getValidatedId());
Log.d("Custom-UI", "First Name = " + profileMap.getFirstName());
Log.d("Custom-UI", "Last Name = " + profileMap.getLastName());
Log.d("Custom-UI", "Email = " + profileMap.getEmail());
Log.d("Custom-UI", "Gender = " + profileMap.getGender());
Log.d("Custom-UI", "Country = " + profileMap.getCountry());
Log.d("Custom-UI", "Language = " + profileMap.getLanguage());
Log.d("Custom-UI", "Location = " + profileMap.getLocation());
Log.d("Custom-UI", "Profile Image URL = " + profileMap.getProfileImageURL());
获取联系人
通过getContactListAsync（）方法获取用户联系人，并在contactDataListener中接收响应。您可以获取Facebook的名字，姓氏和个人资料网址。
private final class ResponseListener implements DialogListener
{
public void onComplete(Bundle values) {
adapter.getContactListAsync(new ContactDataListener());
}
}
// To receive the contacts response after authentication
private final class ContactDataListener implements SocialAuthListener> {
@Override
public void onExecute(List t) {
Log.d("Custom-UI", "Receiving Data");
List contactsList = t;
if (contactsList != null && contactsList.size() > 0) {
for (Contact c : contactsList) {
Log.d("Custom-UI", "Contact ID = " + c.getId());
Log.d("Custom-UI", "First Name = " + c.getFirstName());
Log.d("Custom-UI", "Last Name = " + c.getLastName());
}
}
获取用户Feed
通过getFeedListAsync（）方法获取用户提要并在feedDataListener中接收响应。你可以得到
屏幕名称，消息，创建日期以及发布Feed的用户名称。
private final class ResponseListener implements DialogListener
{
public void onComplete(Bundle values) {
adapter.getFeedsAsync(new FeedDataListener());
}
}
// To receive the feed response after authentication
private final class FeedDataListener implements SocialAuthListener> {
@Override
public void onExecute(List t) {
Log.d("Share-Bar", "Receiving Data");
List feedList = t;
if (feedList != null && feedList.size() > 0) {
for (Feed f : feedList) {
Log.d("Custom-UI ", "Feed ID = " + f.getId());
Log.d("Custom-UI", "Screen Name = " + f.getScreenName());
Log.d("Custom-UI", "Message = " + f.getMessage());
Log.d("Custom-UI ", "Get From = " + f.getFrom());
Log.d("Custom-UI ", "Created at = " + f.getCreatedAt());
}
}
}
获取相册
通过getAlbumsAsync（）方法获取用户相册，并在albumDataListener中接收响应。你可以得到
相册名称，封面照片，照片数量，图片阵列及其名称和网址。
private final class ResponseListener implements DialogListener
{
public void onComplete(Bundle values) {
adapter.getAlbumsAsync(new AlbumDataListener());
}
}
// To receive the album response after authentication
private final class AlbumDataListener implements SocialAuthListener> {
@Override
public void onExecute(List t) {
Log.d("Custom-UI", "Receiving Data");
List albumList = t;
if (albumList != null && albumList.size() > 0) {
// Get Photos inside Album
for (Album a : albumList) {
Log.d("Custom-UI", "Album ID = " + a.getId());
Log.d("Custom-UI", "Album Name = " + a.getName());
Log.d("Custom-UI", "Cover Photo = " + a.getCoverPhoto());
Log.d("Custom-UI", "Photos Count = " + a.getPhotosCount());
photosList = a.getPhotos();
if (photosList != null && photosList.size() > 0) {
for (Photo p : photosList) {
Log.d("Custom-UI", "Photo ID = " + p.getId());
Log.d("Custom-UI", "Name = " + p.getTitle());
Log.d("Custom-UI", "Thumb Image = " + p.getThumbImage());
Log.d("Custom-UI", "Small Image = " + p.getSmallImage());
Log.d("Custom-UI", "Medium Image = " + p.getMediumImage());
Log.d("Custom-UI", "Large Image = " + p.getLargeImage());
}}
}}
上传图片
通过调用adapter.uploadimageAsync（）来共享您的图像，并验证UploadImageListener中的响应。
private final class ResponseListener implements DialogListener
{
public void onComplete(Bundle values) {
adapter.uploadImageAsync("Landscape Images", "icon.png", bitmap, 0,new UploadImageListener());
}
}
// To get status of image upload after authentication
private final class UploadImageListener implements SocialAuthListener {
@Override
public void onExecute(Integer t) {
Log.d("Custom-UI", "Uploading Data");
Integer status = t;
Log.d("Custom-UI", String.valueOf(status));
Toast.makeText(CustomUI.this, "Image Uploaded", Toast.LENGTH_SHORT).show();
}
}
