urS*_*Sus 39 android login button facebook-android-sdk
我正在编写一个与Facebook SDK集成的应用程序,以分享一些(字符串)内容作为墙贴.现在,我让HelloFacebookSample工作了.但是它使用LoginButton来记录用户.
我不希望这样.我想要做的就是点击操作栏中的我的分享按钮并分享到Facebook.因此,我想以编程方式登录,我试图模拟LoginButton的功能,但到目前为止还没有成功.我明白了

好吧,这仍然是HelloFacebookSample项目,我试图弯曲正确的方式.我唯一使用的是performPublish方法,创建会话的东西.
希望有一个更简单的方法!PS:我正在使用Facebook SDK 3

你发布了整个活动的内容吗？
您还需要覆盖onActivityResult,并将值传递给Session.getActiveSession().onActivityResult(...).否则,会话将不知道用户已授权您的应用程序,这就是您看到错误的原因(会话认为仍有待处理的身份验证请求,这就是您无法重新授权发布的原因).

因为我和@ Beppi对@Ming Li的评论赞不绝口,因为我和我在应用程序中使用Facebook SDK,因此我决定创建更简化的API级别,这是基于最新的Facebook SDK 3.0.b.

对于你的问题: How to login programatically?
设置登录/注销侦听器
// set login / logout listener
OnLoginOutListener onLoginOutListener = new SimpleFacebook.OnLoginOutListener()
{
@Override
public void onFail()
{
Log.w(TAG, "Failed to login");
}
@Override
public void onException(Throwable throwable)
{
Log.e(TAG, "Bad thing happened", throwable);
}
@Override
public void onThinking()
{
// show progress bar or something to the user while login is happening
Log.i(TAG, "In progress");
}
@Override
public void onLogout()
{
// change the state of the button or do whatever you want
Log.i(TAG, "Logged out");
}
@Override
public void onLogin()
{
// change the state of the button or do whatever you want
Log.i(TAG, "Logged in");
}
};
// set the listener
mSimpleFacebook.setLogInOutListener(onLoginOutListener);
点击任何视图,只需调用login(Activity)方法
mSimpleFacebook.login(MainActivity.this);
注销通话logout()方法.像这样:
mSimpleFacebook.logout();
如何在登录前设置权限,请在此处查看非常友好的解释.
希望它对某人有帮助:)
