我想通过Android Face book SDK发布状态和图片。 虽然我能够登录并发布状态但不能显示图像。 这是我的代码，图像。事件监听器发布图像的工作，但登录后单击它时没有任何反应。

您可以使用AsyncRunner类在Facebook上发布和图像/照片。
public void publishPhoto(byte[] imgData, string message) {
AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner (facebook);
Bundle parameters = new Bundle ();
parameters.putString (Facebook.TOKEN, facebook.getAccessToken());
parameters.putString ("message", message);
parameters.putByteArray ("source", imgData);
mAsyncRunner.Request ("me/photos", parameters, "POST", new RequestListener (), null);
}
在sharephoto上点击此方法。

从最新的SDK使用GraphRequestAsyncTask
Set<String> permissions = AccessToken.getCurrentAccessToken().getPermissions();
AccessToken accessToken = AccessToken.getCurrentAccessToken();
Bundle postParams = new Bundle();
postParams.putString("message", msg);
postParams. putByteArray ("source", imgData);
GraphRequest request = new GraphRequest(accessToken, "me/photos", postParams, HttpMethod.POST, null);
GraphRequestAsyncTask asynTaskGraphRequest = new GraphRequestAsyncTask (request);
asynTaskGraphRequest.execute();
P.S假设您拥有所有必需的许可。

这是我找到的解决方案：
如果您想在登录前在墙上发布您需要这样做的图像：
private static List<String> PERMISSIONS =
Arrays.asList("public_profile","user_photos","user_videos", "email","user_likes","user_posts",
"user_hometown", "user_location","user_about_me","user_birthday",
"user_friends","user_relationship_details");
LoginManager.getInstance().logInWithPublishPermissions(this,Arrays.asList("publish_actions"));
LoginManager.getInstance().registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
@Override
public void onSuccess(LoginResult loginResult) {
// App code
Log.i(TAG,"onSuccess registerCallback");
}
@Override
public void onCancel() {
// App code
Log.i(TAG,"onCancel registerCallback");
}
@Override
public void onError(FacebookException exception) {
// App code
Log.i(TAG,"onError registerCallback");
}
});
然后你需要调用这个方法：
/**
* This is a method which can post an image to the facebook wall.
* @throws IOException
*/
private void sharePhoto() throws IOException {
BitmapFactory.Options bmOptions = new BitmapFactory.Options();
bmOptions.inPreferredConfig = Bitmap.Config.ARGB_8888;
String imageUri = "drawable://" + R.drawable.gift_icon;
/*OR*/
Uri path = Uri.parse("android.resource://dxswifi_direct.com.wifidirectcommunication/" + R.drawable.gift_icon);
Uri otherPath = Uri.parse("android.resource://dxswifi_direct.com.wifidirectcommunication/drawable/gift_icon");
String path1 = path.toString();
String path2 = otherPath.toString();
imageUri = "http://i.dailymail.co.uk/i/pix/2015/04/22/21/27DEB82000000578-3051045-image-a-25_1429735533586.jpg";
URL url = new URL(imageUri);
Bitmap image = BitmapFactory.decodeStream(url.openConnection().getInputStream());
/*SharePhoto photo = new SharePhoto.Builder().setBitmap(image).build();
Bitmap image = BitmapFactory.decodeFile(imageUri, bmOptions);*/
SharePhoto photo = new SharePhoto.Builder().setBitmap(image).build();
SharePhotoContent content = new SharePhotoContent.Builder().addPhoto(photo).build();
Toast.makeText(getApplicationContext(), getString(R.string.facebook_uploading), Toast.LENGTH_SHORT).show();
ShareApi.share(content, new FacebookCallback<Sharer.Result>() {
@Override
public void onSuccess(Sharer.Result result)
{
Toast.makeText(getApplicationContext(), getString(R.string.facebook_successful), Toast.LENGTH_SHORT).show();
}
@Override
public void onCancel()
{
Log.v("FACEBOOK_TEST", "share api cancel");
}
@Override
public void onError(FacebookException e)
{
Log.v("FACEBOOK_TEST", "share api error " + e);
}
});
}
