正如您在您的评论提到，该文档的Deezer说，DialogListener有3种方法：
onCancel（）的onComplete（束值），onException的（例外的例外）。

As you mention in your comment, the Deezer doc says that DialogListener has 3 methods: onCancel(), onComplete(Bundle values), onException(Exception exception).

所以，你必须实现只有这3个功能。

So you have to implements ONLY these 3 functions.

        @Override
        public void onComplete(Bundle values) {
            // store the current authentication info 
            SessionStore sessionStore = new SessionStore();
            sessionStore.save(mDeezerConnect, LoginActivity.this);

            // Launch the Home activity
            Intent intent = new Intent(LoginActivity.this, HomeActivity.class);
            startActivity(intent);
        }


        @Override
        public void onCancel() {
            Toast.makeText(LoginActivity.this, R.string.login_cancelled, Toast.LENGTH_LONG).show();
        }

        @Override
        public void onException(Exception e) {
          //    ...
        }

和删除其他方法：onError的，等等。也许你的例子，正如你提到的，对于SDK的另一个版本。

And remove the other methods: onError, etc. Maybe you example, as you suggest, is for another version of the SDK.

请注意：我不使用Android的工作室，但在Eclipse你有一个命令来自动创建需要的方法（空，以提'TODO'）。也许同样存在于Android的工作室？

Note: I don't use Android Studio, but in Eclipse you have a command to automatically create needed methods (empty, with mention 'TODO'). Maybe the same exists in Android Studio?
