我正在尝试从facebook会话中获取姓名和电子邮件。我想在EditText中添加这些信息。当我尝试获取这些信息时，Facebook会打开以输入我的登录名和密码，以便在此不返回信息后进行访问。
我该怎么做？
我正在尝试这个。

答案 0 :(得分：1)
您可以执行以下操作。
Request.newMeRequest(session, new Request.GraphUserCallback()
{
@Override
public void onCompleted(GraphUser user, Response response)
{
if (response != null)
{
try
{
String name = user.getName();
String email = (String) user.getProperty("email");
Log.e(LOG_TAG, "Name: " + name + " Email: " + email);
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
}).executeAsync();
P.S。应在运行此请求之前打开会话。您可以通过sessionState方法检查isOpened()
