Question

这是我的活动课：

 public class activity extends AppCompatActivity{
 @Override
 protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity);

Intent i = new Intent(activity.this, Service.class);
                    PendingIntent pIntent = PendingIntent.getService(getApplicationContext(), 0, i, PendingIntent.FLAG_UPDATE_CURRENT);
                    AlarmManager aManager = (AlarmManager) getSystemService(ALARM_SERVICE);
                      Calendar c=Calendar.getInstance();
                      c.set(Calendar.HOUR_OF_DAY,mHour);
                      c.set(Calendar.MINUTE,mMinute);
                      c.set(year,month,date);
                      c.setTimeInMillis(System.currentTimeMillis());
                    aManager.set(AlarmManager.RTC_WAKEUP, c.getTimeInMillis(), pIntent);
                    Toast.makeText(getApplicationContext(), "Service triggered", Toast.LENGTH_SHORT).show();
                    startService(i);
                    }
                    }

这是我的服务班级：

public class Smscreator extends Service {

@Override
public IBinder onBind(Intent intent) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public int onStartCommand(Intent i, int flags, int startId) {
    // TODO Auto-generated method stub

    Context context=getApplicationContext();

    Toast.makeText(context, "This is the service.",
            Toast.LENGTH_LONG).show();

    return START_STICKY;
}

}

这是我的清单类：

 <?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapplication">
    <application
                <service
                android:name=".Service"
                android:enabled="true"
                android:exported="true"></service>
                <activity android:name=".activity" 
                <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
                </intent-filter>
                </activity>
            </application>

            </manifest>

变量mHour，mMinute，year，month和date是取决于用户的日期和时间的某些值。

现在，当我执行此代码时，该服务立即被触发；它完全忽略了用户指定的日期和时间。有人可以帮我吗？

编辑：我目前正在使用Android M。

如何触发服务在特定日期和时间启动？
