从您的代码，这似乎是预期的结果。首先调用openActiveSession，它将显示auth对话框。然后，获得初始权限后，您调用publishStory，它将请求新的发布权限，并且它将再次显示auth对话框。 –

我解决了它这样的：

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    callbackManager.onActivityResult(requestCode, resultCode, data); 
    if (AccessToken.getCurrentAccessToken() != null){ 
     if (!AccessToken.getCurrentAccessToken().getPermissions().contains("publish_actions")){ 
      LoginManager.getInstance().logInWithPublishPermissions(MainActivity.this, Arrays.asList("publish_actions")); 
     } 
    } 
}

但它第一次会显示两个登录权限，一个具有普通权限，另一个具有发布权限 – Hanuman

对我来说也是Facebook登录对话框中显示两次，当我点击“登录“Facebook按钮。

我刚刚更改了Facebook的默认按钮，并使用了正常按钮，并带有Facebook按钮背景，现在登录页面只显示一次。

Facebook默认按钮显示正常和发布权限的登录页面。我不知道细节，但这对我有用。
