如何使用对话框在 Facebook 墙上发布图像

Question

我正在使用Facebook SDK并在我的应用程序中调用WebDialog在Facebook上发布一些东西，它可以发布文本但不能发布图片，它不能使用params.putByteArray来做?

如何使用webDialog 解决这个问题？

Bundle params = new Bundle();
params.putByteArray("picture",  baos.toByteArray());

WebDialog feedDialog = (
    new WebDialog.FeedDialogBuilder(CameraActivity.this,
        mData.sFB,
        params))
    .setOnCompleteListener(new OnCompleteListener(){
        @Override
        public void onComplete(Bundle values,FacebookException error) {
        })
        .build();                   
feedDialog.show();

您可以为此使用 Simple facebook，它非常易于使用。发布完整课程供您参考，只需参考并检查。

 package com.core;

    import android.content.Intent;
    import android.os.Bundle;
    import android.view.Window;
    import android.widget.Toast;

        class OnLoginListener implements SimpleFacebook.OnLoginListener {

单独picture 不行，你还得给一些link。逻辑对吗？

在发布提要时，如果您想添加图片，则必须有一些链接和相关的说明/标题（可选）。因为 Feed 中的图片与您分享的链接相关联。以下是 Feed 的外观-

如果您一个人想发布照片 - 这不是提要；您应该改用/photos API 并发布照片。

所以将picture 和link 添加到参数中，否则更改API。
