我正在使用phonegap从设备相机或图库中抓取图像。相机部分工作正常,但当我点击调用galleryButton()的按钮时,应用程序就会卡住。这是我使用的代码:phonegap Camera.PictureSourceType.PHOTOLIBRARY不适用于android

function cameraButton() { 
    callLib(Camera.PictureSourceType.CAMERA); 
} 

function galleryButton() { 
    callLib(Camera.PictureSourceType.PHOTOLIBRARY); 
} 

function callLib(sourceType) { 
    navigator.camera.getPicture(onSuccess, onFail, { quality: 50, 
                 destinationType : Camera.DestinationType.DATA_URL, 
                 sourceType : sourceType, 
                 allowEdit : false, 
                 encodingType: Camera.EncodingType.JPEG, 
                 targetWidth: 512, 
                 targetHeight: 512, 
                 saveToPhotoAlbum: false }); 
} 

logcat的输出:

我有以下权限:

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/> 
<uses-permission android:name="android.permission.CAMERA"/> 

编辑 一切都是完美的。 galleryButton()永远不会被调用:P我的错误。有人关闭了这个问题。

这些可选参数仅用于自定义相机设置。 allowEdit:假的, 编码类型:Camera.EncodingType.JPEG, targetWidth:512, targetHeight:512,

作出photolib一个新的功能将包含 品质:40, destinationType: sourceType的:
