使用 Gluon-mobile 中的 ALARM_SERVICE 服务安排 Android 中的任务
Schedule a Task in Android using ALARM_SERVICE service in Gluon-mobile
我参考了这个 link 并尝试了这个代码 所以 far.But 我不知道在 gluon-mobile 中实现这个代码。什么我打算做的是我想开始一个缩进，在特定的后台做一些工作 time.My 问题是我不知道 gluon-mobile behaves.So 如何帮助我完成它。
package com.application;
import java.util.Calendar;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import javafxports.android.FXActivity;
public class Schedular {
AlarmManager manager=null;
FXActivity activity=null;
public Schedular()
{
manager=(AlarmManager) FXActivity.getInstance().getSystemService(Context.ALARM_SERVICE);
activity=FXActivity.getInstance();
}
public void schedule()
{
Intent indent = new Intent(activity,Alarm.class);
PendingIntent pIntent = PendingIntent.getBroadcast(activity, 0, indent, 0);
manager.set(AlarmManager.RTC_WAKEUP, SystemClock.elapsedRealtime()+2*1000,indent); //This is Where I went Wrong
}
}
我想在 运行-time 用户指定的特定时间安排任务，这就是函数 public void schedule(Calendar calendar,boolean flag ) 确实如此。
Alarm.class
public class Alarm extends BroadcastReceiver
{
@Override
public void onReceive(Context context, Intent intent)
{
// Your code to execute when the alarm triggers
// and the broadcast is received.
new bluetooth.turnOn();
}
并且我已将 Alarm.class 添加到 AndroidManifest.xml 为
<?xml version="1.0" encoding="UTF-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.application" android:versionCode="1" android:versionName="1.0">

<receiver android:name="com.application.Alarm" /> // this is where I have included the Alarm.class
<receiver android:name="com.gluonhq.impl.charm.down.plugins.android.AlarmReceiver" />
</application>
当调用 schedule 方法时，应用程序退出...
我有 运行 adb logcat -v threadtime 并在 cmd
上得到了这个输出

try{
Schedule schedule =(Schedule) Class.forName("com.application.Schedular").newInstance();
schedule.schedule();
}
替换缩进
来自
manager.setRepeating(AlarmManager.RTC_WAKEUP, calendar.getTimeInMillis(), 10L, pIntent);
也给indent的构造函数，传递所需的"activity"或"service"
Intent intent = new Intent(context, AlarmReceiver.class); //AlarmReceiver is an activity that will be launched after an hour
PendingIntent pIntent = PendingIntent.getBroadcast(context, 0, intent, 0);
alarmMgr.set(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime() +
60 * 1000, pIntent); //60mins from now
您的代码并不完全适合我：我不得不将 intent 更改为 schedule() 中的 pIntent，并将 Schedule 更改为 Class 在 Java 实现上（你如何导入它？）。除此之外，对我来说运行宁没问题（使用Android目标25），我没有任何例外。
我将 post 初始解决方案（基于您的方法），然后是更好的方法。
初步解决方案
虽然添加平台特定代码的首选方法是遵循 Charm Down 设计模式（参见 https://bitbucket.org/gluon-oss/charm-down），但让 Android 代码正常工作的一种非常快速且肮脏的方法是：

这是使用 Gluon IDE 插件的单一视图模板项目的基本视图：

button.setOnAction(e -> {
try {

} catch (ClassNotFoundException | InstantiationException | IllegalAccessException ex) {

protected void updateAppBar(AppBar appBar) {
appBar.setNavIcon(MaterialDesignIcon.MENU.button(e -> System.out.println("Menu")));
appBar.setTitleText("Basic View");
}
}

部署到您的 Android 设备 (./gradlew androidInstall) 和 运行。按下按钮，两秒后你会看到吐司：
首选解决方案
报警服务
虽然上面的代码有效，但是使用起来不是很方便Class.forName。
按照 Charm Down 服务（例如 LocalNotification），我将改为这样做（您必须保持相同的包名称）：
Java
AlarmService.java
package com.gluonhq.charm.down.plugins;
public interface AlarmService {
public void schedule();
}
AlarmServiceFactory.java
package com.gluonhq.charm.down.plugins;
import com.gluonhq.charm.down.DefaultServiceFactory;
public class AlarmServiceFactory extends DefaultServiceFactory<AlarmService> {
public AlarmServiceFactory() {
super(AlarmService.class);
}
}
Android
AndroidAlarmService.java
package com.gluonhq.charm.down.plugins.android;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.SystemClock;
import com.gluonhq.charm.down.plugins.AlarmService;
import com.gluonhq.scheduler.android.AlarmReceiver;
import javafxports.android.FXActivity;
public class AndroidAlarmService implements AlarmService {
private final AlarmManager manager;
private final FXActivity activity;
public AndroidAlarmService() {
activity = FXActivity.getInstance();
manager = (AlarmManager) activity.getSystemService(Context.ALARM_SERVICE);
}
@Override
public void schedule() {
Intent indent = new Intent(activity, AlarmReceiver.class);
PendingIntent pIntent = PendingIntent.getBroadcast(activity, 0, indent, 0);
manager.set(AlarmManager.RTC_WAKEUP, SystemClock.elapsedRealtime() + 2000, pIntent);
}
}
（保持与上面相同的AlarmReceiver class）。
最后，在您看来：
BasicView.java
button.setOnAction(e ->
Services.get(AlarmService.class).ifPresent(AlarmService::schedule));
现在可以再次部署和运行，结果是一样的。但显然，这种首选方式具有更多优势。
- 使用该服务，您还可以 运行 在桌面上或部署到 iOS：该应用程序将运行（单击按钮时它不会执行任何操作）。
- 如果需要，您可以实施桌面和 iOS 解决方案。
- 您可以通过界面轻松添加更多功能。

Main/Java
这是使用 Gluon IDE 插件的单一视图模板项目的基本视图：
胶子Scheduler.java
package com.gluonhq.scheduler;
import com.gluonhq.charm.glisten.application.MobileApplication;
import com.gluonhq.charm.glisten.visual.Swatch;
import javafx.scene.Scene;
import javafx.scene.image.Image;
import javafx.stage.Stage;
public class GluonScheduler extends MobileApplication {
public static final String BASIC_VIEW = HOME_VIEW;
@Override
public void init() {
addViewFactory(BASIC_VIEW, () -> new BasicView(BASIC_VIEW));
}
@Override
public void postInit(Scene scene) {
Swatch.BLUE.assignTo(scene);
((Stage) scene.getWindow()).getIcons().add(new Image(GluonScheduler.class.getResourceAsStream("/icon.png")));
}
}
BasicView.java
package com.gluonhq.scheduler;
import com.gluonhq.charm.glisten.control.AppBar;
import com.gluonhq.charm.glisten.control.Icon;
import com.gluonhq.charm.glisten.mvc.View;
import com.gluonhq.charm.glisten.visual.MaterialDesignIcon;
import java.util.logging.Level;
import java.util.logging.Logger;
import javafx.geometry.Pos;
import javafx.scene.control.Button;
import javafx.scene.layout.VBox;
public class BasicView extends View {
public BasicView(String name) {
super(name);
Button button = new Button("Schedule task");
button.setGraphic(new Icon(MaterialDesignIcon.ALARM_ON));
button.setOnAction(e -> {
try {
Class c = Class.forName("com.gluonhq.scheduler.android.Scheduler");
c.newInstance();
} catch (ClassNotFoundException | InstantiationException | IllegalAccessException ex) {
Logger.getLogger(BasicView.class.getName()).log(Level.SEVERE, null, ex);
}
});
VBox controls = new VBox(button);
controls.setAlignment(Pos.CENTER);
setCenter(controls);
}
@Override
protected void updateAppBar(AppBar appBar) {
appBar.setNavIcon(MaterialDesignIcon.MENU.button(e -> System.out.println("Menu")));
appBar.setTitleText("Basic View");
}
}

部署到您的 Android 设备 (./gradlew androidInstall) 和 运行。按下按钮，两秒后你会看到吐司：
首选解决方案
报警服务
虽然上面的代码有效，但是使用起来不是很方便Class.forName。
按照 Charm Down 服务（例如 LocalNotification），我将改为这样做（您必须保持相同的包名称）：
Java
AlarmService.java
package com.gluonhq.charm.down.plugins;
public interface AlarmService {
public void schedule();
}
AlarmServiceFactory.java
package com.gluonhq.charm.down.plugins;
import com.gluonhq.charm.down.DefaultServiceFactory;
public class AlarmServiceFactory extends DefaultServiceFactory<AlarmService> {
public AlarmServiceFactory() {
super(AlarmService.class);
}
}
Android
AndroidAlarmService.java
package com.gluonhq.charm.down.plugins.android;
import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.SystemClock;
import com.gluonhq.charm.down.plugins.AlarmService;
import com.gluonhq.scheduler.android.AlarmReceiver;
import javafxports.android.FXActivity;
public class AndroidAlarmService implements AlarmService {
private final AlarmManager manager;
private final FXActivity activity;
public AndroidAlarmService() {
activity = FXActivity.getInstance();
manager = (AlarmManager) activity.getSystemService(Context.ALARM_SERVICE);
}
@Override
public void schedule() {
Intent indent = new Intent(activity, AlarmReceiver.class);
PendingIntent pIntent = PendingIntent.getBroadcast(activity, 0, indent, 0);
manager.set(AlarmManager.RTC_WAKEUP, SystemClock.elapsedRealtime() + 2000, pIntent);
}
}
（保持与上面相同的AlarmReceiver class）。
最后，在您看来：
BasicView.java
button.setOnAction(e ->
Services.get(AlarmService.class).ifPresent(AlarmService::schedule));
现在可以再次部署和运行，结果是一样的。但显然，这种首选方式具有更多优势。
- 使用该服务，您还可以 运行 在桌面上或部署到 iOS：该应用程序将运行（单击按钮时它不会执行任何操作）。
- 如果需要，您可以实施桌面和 iOS 解决方案。
- 您可以通过界面轻松添加更多功能。
