按Facebook登录按钮什么都不做 [英] Pressing Facebook Login button does nothing

问题描述

这是我如何实现FB登录按钮的回调机制：

Here is how I implemented callback mechanism for FB login button:

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        FacebookSdk.sdkInitialize(getApplicationContext());
        AppEventsLogger.activateApp(this);
        setContentView(R.layout.activity_main);

        loginButton = (LoginButton)findViewById(R.id.login_button);

        callbackManager = CallbackManager.Factory.create();

        loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
            @Override
            public void onSuccess(LoginResult loginResult) {

                Log.d("FB onSuccess 1", "");
            }

            @Override
            public void onCancel() {
                Log.d("FB onCancel 1", "");
            }

            @Override
            public void onError(FacebookException e) {
                Log.d("FB onError 1", "");
            }
        });
    }

当按下一个微调框出现时，启动，但确认屏幕不会出现，并且没有日志消息被填充到活动监视器中。有什么问题？

When pressing button a spinner appear, starts, but the confirmation screen does not appear, and no log messages are filled into Activity Monitor. What is the problem?

推荐答案

尝试在您的活动中添加：

Try Adding this in your Activity :

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    callbackManager.onActivityResult(requestCode, resultCode, data);

}
