我在
https://developers.facebook.com/docs/getting-started/facebook-sdk-for-android/3.0/跟随“使用Facebook登录创建新的Android项目”部分的步骤登录过程很好.因为我想使用本机Android按钮供用户登录,所以我将以下代码移动到原生Android按钮的View.OnClickListener()中稍微修改代码.以下是侦听器中的代码：
Session.openActiveSession(MainActivity.this,true,new Session.StatusCallback() {
// callback when session changes state
@Override
public void call(Session session,SessionState state,Exception exception) {
if (session.isOpened()) {
// make request to the /me API
Request.executeMeRequestAsync(session,new Request.GraphUserCallback() {
// callback after Graph API
// response with user object
@Override
public void onCompleted(GraphUser user,Response response) {
if (user != null) {
Toast.makeText(getApplicationContext(),"Hello " + user.getName() +" "+user.getId()+"!",Toast.LENGTH_LONG).show();
}
}
});
}
}
});
onActivityResult()和AndroidManifest.xml与教程相同
@Override
public void onActivityResult(int requestCode,int resultCode,Intent data) {
super.onActivityResult(requestCode,resultCode,data);
Session.getActiveSession().onActivityResult(this,requestCode,data);
}
但是,我想在用户成功登录时请求“read_friendlists”.我在https://developers.facebook.com/docs/tutorials/androidsdk/3.0/scrumptious/authenticate/阅读了教程,但它使用了Facebook SDK自定义按钮.如何使用上面显示的代码之类的原生Android按钮实现相同的行为？
