我试过这个:当isSessionValid getDetails直接使用facebook.authorize然后在onActivityResult中获取getDetails
public class MainActivity extends Activity {
Facebook facebook = new Facebook("xxxxxxxxxxxxxxxx");
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
private SharedPreferences mPrefs;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mPrefs = getPreferences(MODE_PRIVATE);
String access_token = mPrefs.getString("access_token", null);
long expires = mPrefs.getLong("access_expires", 0);
if (access_token != null) {
facebook.setAccessToken(access_token);
}
if (expires != 0) {
facebook.setAccessExpires(expires);
}
if (!facebook.isSessionValid()) {
facebook.authorize(this, new String[] {}, new DialogListener() {
@Override
public void onComplete(Bundle values) {
SharedPreferences.Editor editor = mPrefs.edit();
editor.putString("access_token", facebook.getAccessToken());
editor.putLong("access_expires",
facebook.getAccessExpires());
editor.commit();
}
@Override
public void onFacebookError(FacebookError error) {
}
@Override
public void onError(DialogError e) {
}
@Override
public void onCancel() {
}
});
}else{
try {
JSONObject json = Util.parseJson(facebook.request("me"));
String facebookID = json.getString("id");
String firstName = json.getString("first_name");
String lastName = json.getString("last_name");
String email = json.getString("email");
String gender = json.getString("gender");
} catch (Exception e) {
}
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
facebook.authorizeCallback(requestCode, resultCode, data);
try {
JSONObject json = Util.parseJson(facebook.request("me"));
String facebookID = json.getString("id");
String firstName = json.getString("first_name");
String lastName = json.getString("last_name");
String email = json.getString("email");
String gender = json.getString("gender");
} catch (Exception e) {
}
}
public void onResume() {
super.onResume();
facebook.extendAccessTokenIfNeeded(this, null);
}
}
当我在我的系统上安装了facebook应用程序时,此功能正常。但如果没有安装,我会得到一个Web View来输入facebook凭据,而logcat显示login-success,但是没有一个getDetails块被调用。

在 initFacebook()
功能中,通过您可以登录并执行您的功能,在这里我将获取用户的朋友信息。
private void initFacebook()
{
try
{
if (APP_ID == null)
{
Util.showAlert(this,"Warning","Facebook Applicaton ID must be "+ "specified before running this example: see Example.java");
}
mFacebook = new Facebook();
mAsyncRunner = new AsyncFacebookRunner(mFacebook);
mFacebook.authorize(FacebookList.this, APP_ID, new String[] {"email", "read_stream", "user_hometown", "user_location","friends_about_me", "friends_hometown", "friends_location","user_relationships", "friends_relationship_details","friends_birthday", "friends_education_history","friends_website" }, new DialogListener()
{
public void onComplete(Bundle values)
{
getHTTPConnection();
}
public void onFacebookError(FacebookError error)
{
Log.i("public void onFacebookError(FacebookError error)....","....");
}
public void onError(DialogError e)
{
Log.i("public void onError(DialogError e)....", "....");
CustomConfirmOkDialog dialog = new CustomConfirmOkDialog(FacebookList.this, R.style.CustomDialogTheme, Utils.FACEBOOK_CONNECTION_ERROR);
dialog.show();
}
public void onCancel()
{
Log.i("public void onCancel()....", "....");
}
});
SessionStore.restore(mFacebook, this);
SessionEvents.addAuthListener(new SampleAuthListener());
SessionEvents.addLogoutListener(new SampleLogoutListener());
}
catch (Exception e)
{
e.printStackTrace();
}
}
在 getHTTPConnection()
中,继续进行连接和发送字段,我们需要关于用户的朋友,我们可以看到传递字段是朋友的fields=id,first_name,last_name,location,picture
。在这里,您可以根据应用程序的要求更改此字段。
private void getHTTPConnection()
{
try
{
mAccessToken = mFacebook.getAccessToken();
HttpClient httpclient = new DefaultHttpClient();
String result = null;
HttpGet httpget = new HttpGet("https://graph.facebook.com/me/friends?access_token="+ mAccessToken + "&fields=id,first_name,last_name,location,picture");
HttpResponse response;
response = httpclient.execute(httpget);
HttpEntity entity = response.getEntity();
if (entity != null)
{
result = EntityUtils.toString(entity);
parseJSON(result);
}
}
catch (Exception e)
{
e.printStackTrace();
}
}
现在,在成功连接 facebook 后,我们会收到JSON
个数据并进一步解析它。
private void parseJSON(String data1) throws Exception,NullPointerException, JSONException
{
try
{
JSONObject jObj = new JSONObject(data1);
JSONArray jObjArr = jObj.optJSONArray("data");
int lon = jObjArr.length();
for (int i = 0; i < lon; i++)
{
JSONObject tmp = jObjArr.optJSONObject(i);
String temp_image = tmp.getString("picture"); String temp_fname = tmp.getString("first_name");
String temp_lname = tmp.getString("last_name");
String temp_loc = null;
JSONObject loc = tmp.getJSONObject("location");
temp_loc = loc.getString("name");
}
}
catch (Exception e)
{
Log.i("Exception1 is Here>> ", e.toString());
e.printStackTrace();
}
}
假设您已经在应用中添加了 facebook jar,并且为了继续执行此代码,您可以将 initFacebook()
调用到{{1您的活动
