PhoneGap API用于查询呼叫日志

Question

我刚开始使用phoneGap和Android.建立基本样本.

我想知道,如果有API来获取通话记录.我希望创建一个网格显示:

• 一段时间内未接来电的数量
• 已接来电的数量
• 拨打的电话数量
• 接听电话和来电的总时间

提前致谢.

Answer 1

我做了一些研究并成功构建了一个PhoneGap插件,可以从中获取CallLog android.provider.CallLog.

这将返回一个JSON { Rows: [] },其中Rows是一个包含以下字段(作为Array)的二维调用记录数组,顺序如下:

• 日期(作为UNIX时间戳)
• 数,
• 输入(1-输入,2-输出,3-错过)
• 持续时间(秒)
• 新
• 缓存名称
• 缓存的数字类型
• 缓存的数字标签

详情请访问http://developer.android.com/reference/android/provider/CallLog.Calls.html

我还使用这个插件制作了一个小样本,它会显示拨出电话,未接来电和来电的总数,并将它们绘制在饼图中.该示例使用的是FusionCharts的饼图.

以下是您要深入研究的源代码zip:
