问题描述

我使用PhoneGap的创建android应用。在我需要从图库捕捉图像。所以我写了下面的code捕捉图像

I am using phonegap to create android application. In that i need to capture the image from gallery . So i wrote the following code for capturing image

navigator.camera.getPicture(function(imageURI){

    window.resolveLocalFileSystemURI(imageURI, function(fileEntry){
        fileEntry.file(function(fileObj) { 
        console.log(fileObj.name);
        });
    }, fail);
}, fail, { quality: 100, allowEdit : true,
    targetWidth: 600,
    targetHeight: 600,
    destinationType: destinationType.NATIVE_URI,
    sourceType: pictureSource.PHOTOLIBRARY 
});

这是工作的罚款，并拍摄照片。

It is working fine and capture the image.

问题是，当插入 allowEdit 在相机选项映像名称是changed.If我删除

The problem is when insert allowEdit in camera options the image name is changed.If i remove the

/*allowEdit : true,
        targetWidth: 600,
        targetHeight: 600,*/

默认映像名称是坚持。

default image name is persist.

如何避免重命名编辑的时候。有人有助于摆脱这一问题。

推荐答案

在 的PhoneGap /科尔多瓦（3.3版本）的使用时allowEdit：true和目标高度和宽度作为相机选项相机插件有例如默认名称resize.jpg。

In phonegap / cordova(version 3.3) when using "allowtrue and target height and width" for camera options the camera plugin has a default name like "resize.jpg".

所以它总是存储为 resige.jpg 并且也仅仅是从画廊的当挑图片时，将影像不使用摄像头。

So it always stored as resige.jpg and also it is only for when pick image from gallery not when take image using camera .

所以，你可以更改默认的字符串 cameraLauncher.java （SRC / org.apache.cordova.camera内present）

So you can change the default string in cameraLauncher.java (present inside src/org.apache.cordova.camera)

取而代之的是

// Create an ExifHelper to save the exif data that is lost during compression
 String resizePath = getTempDirectoryPath() + "/resize.jpg";
// Some content: URIs do not map to file paths (e.g. picasa).
 String realPath = FileHelper.getRealPath(uri, this.cordova);

替换该

String realPath = FileHelper.getRealPath(uri, this.cordova);
int postition = realPath.lastIndexOf( '.' );
// your image format like jpg or png
String imageFormat = realPath.substring(postition+1);
// your image name 
String imageName = realPath.substring(0,postition);
//now the default name is changed 
String resizePath = getTempDirectoryPath() + "/"+imageName+"."+imageFormat;
