Question

目前，我使用以下代码：

Bundle params = new Bundle();
//params.putString("message", "I want to post this text only.");
params.putString("name", "Facebook SDK for Android");
params.putString("caption", "Build great social apps and get more installs.");
params.putString("description", "Description");
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() {

但是，我不能仅发布消息，因为捆绑包必须包含＆＃34; link＆＃34;。

这是完整的解决方案。请试试这个，我正在使用此代码并且工作完全正常。如果您没有登录（如果您是第一次使用），您将直接登录屏幕（否则）并且访问令牌存储在本地数据中。之后您可以将文本共享到Facebook墙。

if (facebook.getAccessToken() != null) {

            postOnWall("msg to share");

        } else {
            loginToFacebook();

            }

public void postOnWall(String msg) {
    Log.d("Tests", "Testing graph API wall post");
    try {
        String response = facebook.request("me");
        Bundle parameters = new Bundle();

        parameters.putString("message", msg);
        parameters.putString("description", "test test test");
        // parameters.putByteArray("message", msg);
        response = facebook.request("me/feed", parameters, "POST");
        Log.d("Tests", "got response: " + response);
        if (response == null || response.equals("")
                || response.equals("false")) {
            Log.v("Error", "Blank response");

            Toast.makeText(getApplicationContext(), "FacebookError",Toast.LENGTH_SHORT).show();

        }
    } catch (Exception e) {
        e.printStackTrace();

    }
}

public void loginToFacebook() {

    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);

        Log.d("FB Sessions", "" + facebook.isSessionValid());
    }

    if (expires != 0) {
        facebook.setAccessExpires(expires);
    }

    if (!facebook.isSessionValid()) {
        facebook.authorize(this,
                new String[] { "email", "publish_stream" },
                new DialogListener() {

                    @Override
                    public void onCancel() {
                        // Function to handle cancel event
                    }

                    @Override
                    public void onComplete(Bundle values) {
                        // Function to handle complete event
                        // Edit Preferences and update facebook acess_token
                        SharedPreferences.Editor editor = mPrefs.edit();
                        editor.putString("access_token",
                                facebook.getAccessToken());
                        editor.putLong("access_expires",
                                facebook.getAccessExpires());
                        editor.commit();
                        Toast.makeText(sms_by_id.this,
                                "Successfully Login", Toast.LENGTH_LONG)
                                .show();
                        pwindo.dismiss();

                        // Making Login button invisible

                    }

                    @Override
                    public void onError(DialogError error) {
                        // Function to handle error

                    }

                    @Override
                    public void onFacebookError(FacebookError fberror) {
                        // Function to handle Facebook errors
                        pwindo.dismiss();
                        Toast.makeText(sms_by_id.this, "Facebook Error",
                                Toast.LENGTH_LONG).show();
                    }

                });
    }
}

Answer 2

因为捆绑包必须包含“链接”。

此声明不正确。在参数中，只需包含message属性即可！不提供链接/图片/标题/描述等，因为所有这些仅与链接相关。因此，只需使用message参数，它就会仅作为文本发布。

试试这个

    public class ShareOnFacebook extends Activity{

    private static final String APP_ID = "123456789";
    private static final String[] PERMISSIONS = new String[] {"publish_stream"};

    private static final String TOKEN = "access_token";

            editor.putString(TOKEN, facebook.getAccessToken());
            editor.putLong(EXPIRES, facebook.getAccessExpires());
            return editor.commit();
          }

          public boolean restoreCredentials(Facebook facebook) {
              SharedPreferences sharedPreferences = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE);

您需要做的就是更改用户1632209

动作的Bundle

        Bundle parameters = new Bundle();

        params.putString("message", msg);
        params.putString("description", "test test test");

如何才能在Android中将文字发布到我的Facebook墙上？
