我正在嘗試向我的應用程序添加通知功能。我希望它每天同時運行通知或操作。我現在有這個通知代碼：import android.support.v7.app.AppCompatActivity;import android.os.Bundle;import android.app.NotificationManager;import android.app.PendingIntent;import android.content.Intent;import android.support.v4.app.NotificationCompat;import android.view.View;public class MainActivity extends AppCompatActivity {NotificationCompat.Builder notification;private static final int uniqueID = 45612;@Overrideprotected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    notification = new NotificationCompat.Builder(this);    notification.setAutoCancel(true);    // Build the notification    notification.setSmallIcon(R.drawable.icon);    notification.setTicker("Brook Betterment Plan");    notification.setWhen(System.currentTimeMillis());    notification.setContentTitle("Brook Betterment Plan");    notification.setContentText("Don't forget to enter your daily stats! ");    Intent intent = new Intent(this, MainActivity.class);    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, PendingIntent.FLAG_UPDATE_CURRENT);    notification.setContentIntent(pendingIntent);    // Builds notification and issues it    NotificationManager nm = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);    nm.notify(uniqueID, notification.build());}}謝謝！希望有人知道答案。另外，我希望它不需要任何額外的 Activity 或 Java 類。
