Question

我们正在开发android应用程序，我们正试图在后台服务中静默添加事件。使用以下代码：

package com.red_folder.phonegap.plugin.backgroundservice.sample;

import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Date;
import java.util.TimeZone;


import org.json.JSONException;
import org.json.JSONObject;
import org.json.JSONArray;

import android.annotation.SuppressLint;
import android.content.ContentResolver;
import android.content.ContentValues;
import android.content.Context;
import android.content.Intent;
import android.content.ContentUris;
import android.net.Uri;
import android.os.Bundle;
import android.provider.CalendarContract;
import android.provider.CalendarContract.Events;
import android.provider.CalendarContract.Reminders;
import android.util.Log;

import org.apache.cordova.CallbackContext;
import org.apache.cordova.CordovaPlugin;
import org.apache.cordova.PluginResult;

import com.red_folder.phonegap.plugin.backgroundservice.BackgroundService;


@SuppressWarnings("deprecation")
public class MyService extends BackgroundService {

    private final static String TAG = MyService.class.getSimpleName();

    private String mHelloTo = "World";

    @SuppressLint("NewApi")
    @SuppressWarnings("static-access")
    @Override
    protected JSONObject doWork() {
        JSONObject result = new JSONObject();



            Log.d(TAG, "Start calendar insertion");

            JSONObject jsonArray;

            long calID = 3;
            long startMillis = 0; 
            long endMillis = 0;     
            Calendar beginTime = Calendar.getInstance();
            beginTime.set(2014, 9, 14, 7, 30);
            startMillis = beginTime.getTimeInMillis();
            Calendar endTime = Calendar.getInstance();
            endTime.set(2014, 9, 14, 8, 45);
            endMillis = endTime.getTimeInMillis();


            ContentResolver cr = getContentResolver();
            ContentValues values = new ContentValues();
            values.put(Events.DTSTART, startMillis);
            values.put(Events.DTEND, endMillis);
            values.put(Events.TITLE, "Jazzercise");
            values.put(Events.DESCRIPTION, "Group workout");
            values.put(Events.CALENDAR_ID, calID);
            values.put(Events.VISIBLE, 0);
            values.put(Events.EVENT_TIMEZONE, "America/Los_Angeles");
            Uri uri = cr.insert(Events.CONTENT_URI, values);

            // get the event ID that is the last element in the Uri
            long eventID = Long.parseLong(uri.getLastPathSegment());




            Log.d(TAG, "End calendar insertion");


        return result;  
    }

    @Override
    protected JSONObject getConfig() {
        JSONObject result = new JSONObject();

        try {
            result.put("HelloTo", this.mHelloTo);
        } catch (JSONException e) {
        }

        return result;
    }

    @Override
    protected void setConfig(JSONObject config) {
        try {
            if (config.has("HelloTo"))
                this.mHelloTo = config.getString("HelloTo");
        } catch (JSONException e) {
        }

    }     

    @Override
    protected JSONObject initialiseLatestResult() {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    protected void onTimerEnabled() {
        // TODO Auto-generated method stub

    }

    @Override
    protected void onTimerDisabled() {
        // TODO Auto-generated method stub

    }


}

此代码返回EVENTID，表示它正在向设备日历添加事件，但日历上未显示任何事件。我们可以做些什么来在设备的日历上显示添加的事件？

Answer 1

这是我的代码（包括＆＃34;强制同步＆＃34;最后）在日历中打开和书写。也许你可以在那里找到你的答案，它完美无缺。
