使用Gluon-mobile

标签： android javafx alarmmanager gluon gluon-mobile

我已经提到了link并尝试了此代码到目前为止。但我不知道在 gluon-mobile 中实现此代码。我打算做的是我想在一个特定的时间开始一个在背景中做一些工作的缩进。我的问题是我不知道胶子移动的行为。所以我帮助我完成它。

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

}
}

我想在运行时由用户给出的特定时间安排任务，这是公共无效日程表（日历日历，布尔标志）的功能。<登记/>
的 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();  
 }

我已将Alarm.class添加到AndroidManifest.xml中

 <?xml version="1.0" encoding="UTF-8"?>

<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，app退出... 我已经运行了adb logcat -v threadtime并在cmd上获得了此输出

我不知道为什么我无法实例化接收器（Alarm.class），

@FXML void start()
{

    try{

    Schedule schedule =(Schedule) Class.forName("com.application.Schedular").newInstance();


    schedule.schedule();

    }

2 个答案:

答案 0 :(得分：1)

替换缩进

通过

manager.setRepeating（AlarmManager.RTC_WAKEUP，calendar.getTimeInMillis（），10L， pIntent ）;

对于缩进的构造函数，传递所需的＆＃34;活动＆＃34;或者＆＃34;服务＆＃34; 

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

答案 1 :(得分：1)

您的代码并不适用于我：我必须将intent更改为pIntent中的schedule()，并将Schedule更改为Class关于Java实现（无论如何导入它？）。除此之外，它对我运行良好（使用Android目标25），我没有任何例外。

我将发布初始解决方案（基于您的方法），之后是更好的方法。

初始解决方案

虽然添加平台特定代码的首选方法是遵循Charm Down设计模式（请参阅https://bitbucket.org/gluon-oss/charm-down），但是获取Android代码的一种非常快速和肮脏的方式是：

<强>的Android

Scheduler.java 

package com.gluonhq.scheduler.android;

import android.app.AlarmManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.os.SystemClock;
import javafxports.android.FXActivity;

public class Scheduler {

    private final AlarmManager manager;

    public Scheduler() {
        manager = (AlarmManager) FXActivity.getInstance().getSystemService(Context.ALARM_SERVICE);
        Intent indent = new Intent(FXActivity.getInstance(), AlarmReceiver.class);
        PendingIntent pIntent = PendingIntent.getBroadcast(FXActivity.getInstance(), 0, indent, 0);

        manager.set(AlarmManager.RTC_WAKEUP, SystemClock.elapsedRealtime() + 2000, pIntent); 
    }
}

AlarmReceiver.java 

package com.gluonhq.scheduler.android;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;

public class AlarmReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        Toast.makeText(context, "Alarm ON", Toast.LENGTH_LONG).show();
    }

}

的AndroidManifest.xml 

<?xml version="1.0" encoding="UTF-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.gluonhq.scheduler" android:versionCode="1" android:versionName="1.0">

                        </intent-filter>
                </activity>
                <receiver android:name="com.gluonhq.scheduler.android.AlarmReceiver" />
        </application>
</manifest

主要/爪哇

这是使用Gluon IDE插件的单视图模板项目的基本视图：

GluonScheduler.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");
    }
}

的build.gradle 

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'org.javafxports:jfxmobile-plugin:1.3.6'
    }
}

apply plugin: 'org.javafxports.jfxmobile'

repositories {
    jcenter()
    maven {
        url 'http://nexus.gluonhq.com/nexus/content/repositories/releases'
    }
}

mainClassName = 'com.gluonhq.scheduler.GluonScheduler'

dependencies {
    compile 'com.gluonhq:charm:4.3.5'
}

jfxmobile {
    downConfig {
        version = '3.3.0'
        // Do not edit the line below. Use Gluon Mobile Settings in your project context menu instead
        plugins 'display', 'lifecycle', 'statusbar', 'storage'
    }
    android {
        manifest = 'src/android/AndroidManifest.xml'
    }
    ios {
        infoPList = file('src/ios/Default-Info.plist')
        forceLinkClasses = [
                'com.gluonhq.**.*',
                'javax.annotations.**.*',
                'javax.inject.**.*',
                'javax.json.**.*',
                'org.glassfish.json.**.*'
        ]
    }
}

部署到您的Android设备（./gradlew androidInstall）并运行。按下按钮，两秒钟后你会看到祝酒词：

首选解决方案

<强> AlarmService

虽然上面的代码有效，但使用Class.forName并不是很方便。

在Charm Down服务（例如LocalNotification）之后，我会这样做（你必须保持相同的包名）：

<强>爪哇

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);
    }

}

<强>的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课程。）

最后，在你看来：

BasicView.java 

button.setOnAction(e -> 
        Services.get(AlarmService.class).ifPresent(AlarmService::schedule));

现在您可以再次部署和运行，结果将是相同的。但显然这种首选方式有许多优点。

  • 使用该服务，您也可以在桌面上运行或部署到iOS：应用程序可以正常工作（点击按钮时不会执行任何操作）。
  • 如果需要，您可以为桌面和iOS实施解决方案。
  • 您可以通过界面轻松添加更多功能。
