我有一个片段，其下一个代码是auth并将照片和视频上传到facebook：
private void postPhotoFB(int index) {
AccessToken accessToken = AccessToken.getCurrentAccessToken();
if (accessToken != null) {
if (!pathImagesFB.isEmpty() && index < pathImagesFB.size()
&& uploadFbStatus) {
File ff = new File(pathImagesFB.get(index));
String format = null;
format = URLConnection.guessContentTypeFromName(ff.getName());
ShareApi sA;
L("mimetype: " + format);
if (new MimetypesFileTypeMap().getContentType(ff).toLowerCase().equals("image/png") || new MimetypesFileTypeMap().getContentType(ff).toLowerCase().equals("image/jpg")
|| new MimetypesFileTypeMap().getContentType(ff).toLowerCase().equals("image/jpeg")) {
if (hasPublishPermission()) {
L("sending image");
Bitmap images = ImageUtils.getBitmap(pathImagesFB.get(index), 0);
SharePhoto photo = new SharePhoto.Builder().setBitmap(images).build();
SharePhotoContent contentPhoto = new SharePhotoContent.Builder().addPhoto(photo).build();
sA = new ShareApi(contentPhoto);
if (sA.canShare()) {
sA.share(shareCallback);
} else {
L("cant share photo to fb");
}
} else {
LoginManager.getInstance().logInWithPublishPermissions(this,
PUBLISH_PERMISSIONS);
L("share image to fb get public permission");
}
} else if
(format.toLowerCase().equals("video/avi")) {
if (hasPublishPermission()) {
Uri videoFileUri = Uri.fromFile(ff);
L("share video to fb " + videoFileUri.getPath());
ShareVideo video = new ShareVideo.Builder()
.setLocalUrl(videoFileUri)
.build();
ShareVideoContent contentVideo = new ShareVideoContent.Builder()
.setVideo(video)
.build();
sA = new ShareApi(contentVideo);
if (sA.canShare()) {
sA.share(shareCallback);
} else {
L("cant share video to fb");
}
} else {
LoginManager.getInstance().logInWithPublishPermissions(this,
PUBLISH_PERMISSIONS);
L("share image to fb get public permission");
}
}
} else {
L("postPhoto false to facebook");
uploadFbStatus = false;
}
L("facebook_uploading");
} else {
L("acces token is null");
}
}
private ProfileTracker profileTracker;
FacebookCallback<LoginResult> loginCallback = new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
L("loginCallback onSuccess");
AccessToken a = loginResult.getAccessToken();
L("expired " + a.getExpires());
L("acces token login a " + a);
// ------------ **postPhotoFB(0);** <<<----------------HERE WORKED
}
@Override
public void onCancel() {
Log.e("NEW", "loginCallback onCancel");
}
@Override
public void onError(FacebookException exception) {
Log.e("NEW", "loginCallback onError");
String title = "Error";
String alertMessage = exception.getMessage();
showResult(title, alertMessage);
}
};
private FacebookCallback<Sharer.Result> shareCallback = new FacebookCallback<Sharer.Result>() {
@SuppressLint("NewApi")
@Override
public void onSuccess(Sharer.Result result) {
L("upload to Facebook Succes");
if (result.getPostId() != null && uploadFbStatus) {
FbImageIndex++;
postPhotoFB(FbImageIndex);
}
}
@Override
public void onCancel() {
Log.e("NEW", "shareCallback Canceled");
}
@Override
public void onError(FacebookException error) {
L("Facebook " + String.format("Error: %s", error.toString()));
String title = "Error";
String alertMessage = error.getMessage();
showResult(title, alertMessage);
}
};
private void showResult(String title, String alertMessage) {
new AlertDialog.Builder(getActivity()).setTitle(title)
.setMessage(alertMessage).setPositiveButton("Ok", null)
.show();
}
private boolean hasPublishPermission() {
AccessToken accessToken = AccessToken.getCurrentAccessToken();
return accessToken != null
&& accessToken.getPermissions().contains("publish_actions");
}
@SuppressLint("NewApi")
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (resultCode == Activity.RESULT_OK) {
switch (requestCode) {
case REQUES_FACEBOOK:
callbackManager.onActivityResult(requestCode, resultCode, data);
login_button_fb.setText(getActivity().getResources().getString(R.string.label_logout));
login_button_fb.setBackground(getActivity().getResources().getDrawable(R.drawable.logout));
break;
}
} else {
L("Activitiresult NOT ok " + requestCode);
}
}
问题是当我从FacebookCallback（）onSucces登录并调用我的post方法时（在代码中显示）它就像一个sharm，但是当我从我的代码的任何其他地方调用我的postPhotoFB方法时（比如按钮点击）， shareCallback不会调用evry时间我检查我的访问令牌及其（{AccessToken令牌：ACCESS_TOKEN_REMOVED权限：[public_profile，publish_actions，user_friends，email]}）。
请帮助我理解我的代码中的错误，我想从我班上的任何其他地方调用我的post方法。 感谢。
答案 0 :(得分：0)
而不是AccessToken accessToken = AccessToken.getCurrentAccessToken（） 做 AccessToken accessToken = AccessToken.getCurrentAccessToken（）。getToken（）
