Answer 1

您应该使用putExtra方法发送数据，并在其他活动用户getExtra方法中接收数据。 http://developer.android.com/reference/android/content/Intent.html#putExtra(java.lang.String，float []）

Answer 2

我得到了我的问题的答案使用putExtra和getIntExtra最后我得到了输出。无论如何，感谢farooq arshad。

Intent intent = new Intent(AlarmClock.ACTION_SET_ALARM)
                    //.putExtra(AlarmClock.EXTRA_MESSAGE, message)
                    .putExtra(AlarmClock.EXTRA_HOUR, hour)
                    .putExtra(AlarmClock.EXTRA_MINUTES, minute);

                startActivity(intent);
