Answer 1

将以下两个功能写入您的活动。

public void postToWall() {
    String message="Good Morning to All";
    Bundle parameters = new Bundle();
    parameters.putString("message", message);
    parameters.putString("description", "topic share");
    try {
        facebook.request("me");
        String response = facebook.request("me/feed", parameters, "POST");
        Log.d("Tests", "got response: " + response);
        if (response == null || response.equals("") || response.equals("false")) {
            showToast("Blank response.");
        } else {
            showToast("Message posted to your facebook wall!");
        }
    } catch (Exception e) {
        showToast("Failed to post to wall!");
        e.printStackTrace();
    }
}

2）

public boolean restoreCredentials(Facebook facebook) {
    SharedPreferences sharedPreferences = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE);
    facebook.setAccessToken(sharedPreferences.getString(TOKEN, null));
    facebook.setAccessExpires(sharedPreferences.getLong(EXPIRES, 0));
    return facebook.isSessionValid();
}

3）

public void loginAndPostToWall() {
    facebook.authorize(this, PERMISSIONS, Facebook.FORCE_DIALOG_AUTH, new LoginDialogListener());
}

将以下代码写入墙上的帖子按钮点击事件

facebook = new Facebook(APP_ID);
restoreCredentials(facebook);
if (!facebook.isSessionValid()) {
    loginAndPostToWall();
} else {
    postToWall();
}
