我正在尝试将可绘制文件夹中的图像传递给提要对话框。但我无法在 facebook 提要对话中查看图像。其余参数可用。我正在使用 Facebook SDK 3.5。这是显示提要对话框的功能。
private void publishFeedDialog() {
Bitmap bitmap = BitmapFactory.decodeResource(this.getResources(),R.drawable.ic_launcher);
ByteArrayOutputStream stream = new ByteArrayOutputStream();
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, stream);
byte[] bitMapData = stream.toByteArray();
Bundle params = new Bundle();
params.putByteArray("picture", bitMapData);
params.putString("name", "Facebook SDK for Android");
params.putString("caption", "Build great social apps and get more installs.");
params.putString("description", "The Facebook SDK for Android makes it easier and faster to develop Facebook integrated Android apps.");
params.putString("link", "https://developers.facebook.com/android");
//params.putString("picture", "https://raw.github.com/fbsamples/ios-3.x-howtos/master/Images/iossdk_logo.png");
WebDialog feedDialog = (
new WebDialog.FeedDialogBuilder(getActivity(),
Session.getActiveSession(),
params))
.setOnCompleteListener(new OnCompleteListener() {
@Override
public void onComplete(Bundle values,
FacebookException error) {
if (error == null) {
// When the story is posted, echo the success
// and the post Id.
final String postId = values.getString("post_id");
if (postId != null) {
Toast.makeText(getActivity(),
"Posted story, id: "+postId,
Toast.LENGTH_SHORT).show();
} else {
// User clicked the Cancel button
Toast.makeText(getActivity().getApplicationContext(),
"Publish cancelled",
Toast.LENGTH_SHORT).show();
}
} else if (error instanceof FacebookOperationCanceledException) {
// User clicked the "x" button
Toast.makeText(getActivity().getApplicationContext(),
"Publish cancelled",
Toast.LENGTH_SHORT).show();
} else {
// Generic, ex: network error
Toast.makeText(getActivity().getApplicationContext(),
"Error posting story",
Toast.LENGTH_SHORT).show();
}
}
})
.build();
feedDialog.show();
}
