Question

我正在尝试使用PhoneGap开发来显示设备中的联系人列表。但它没有显示联系人。

它既没有出现任何错误。

请任何人帮助我找出以下代码中的错误，因为我在phonegap中是begginer。

  <!DOCTYPE HTML>
<html>
<head>
<title> Contacts Demo </title>
<script type="text/javascript" src="phonegap-1.1.0.js"></script>
<script type="text/javascript">

    function init()
    {
        document.addEventListener("deviceready",onDeviceReady,false);
    }

    function onDeviceReady()
    {
        var options=new ContactFindOptions();
        options.filter="";
        var fields=["name","phoneNumbers"];
        navigator.service.contacts.find(fields,onSuccess,onError,options);
    }

    function onSuccess(contacts)
    {
        var ulr=document.getElementById("list");
        for(var i=0;i<contacts.length;i++)
        {
            var name=contacts[i].name.formatted;
            var phoneNumber=contacts[i].phoneNumbers[0].value;
            var li=document.createElement('li');
            li.innerHTML = "<a href=\"tel://"+phoneNumber+"\">"+name+"</a>";
            ulr=appendChild(li);
        }
    };

    function onError()
    {
        alert('onError!');
    };
</script>
</head>
<body>
<h1>Contacts List</h1>
<ul id="list"></ul>
</body>
</html>

logcat的：

任何帮助将不胜感激。

感谢。

Answer 1

您是否向AndroidManifest.xml添加了READ_CONTACTS权限？

代码：

<uses-permission android:name="android.permission.READ_CONTACTS" />

我建议你删除功能init()，然后让：

document.addEventListener("deviceready",onDeviceReady,false);

原因是init（）未被触发。

如果您执行了所有Phongap步骤并且没有出现错误，那么您必须尝试最后一次认为过去对我有用，只需保存您的项目数据并执行phonegap build或phonegap build app_platform

Answer 2

检查你的phoneNumbers数组是否为空

PhoneGap-联系人没有显示
