更新：
app.directive('upload', function() {
return {
restrict: 'A',
require: 'ngModel',
link: function(scope, elm, attrs, ctrl) {
elm.on('click', function() {
navigator.camera.getPicture(
function(imageURI) {
scope.$apply(function() {
alert(imageURI);
ctrl.$setViewValue(imageURI);
});
window.resolveLocalFileSystemURI(imageURI, function(fileEntry) {
// ctrl.$setViewValue(imageURI);
alert("inside local file" + imageURI);
alert("Inside local file system");
fileEntry.file(function(fileObj) {
alert("hai");
var options = new FileUploadOptions();
options.fileKey = "file";
options.fileName = fileObj.name;
options.mimeType = fileObj.type;
var ft = new FileTransfer();
// var url = fileUploadUrl;
// ft.upload(imageUri, encodeURI(url), success, failure, options);
});
});
},
function(err) {
ctrl.$setValidity('error', false);
}, {quality: 50,
destinationType: Camera.DestinationType.FILE_URI,
sourceType: Camera.PictureSourceType.PHOTOLIBRARY
}
);
});
}
};
});
我的HTML：
My HTML:
<img
ng-src="{{onepic}}"
width="250"
height="390"
alt="error"/>
我设定值onepic在我的手表function.So内部控制指令时，返回一个URI将在onepic.Please自动设置指定任何替代解决方案，或者荫做错什么，荫新angularjs
I set value for onepic in my controller inside watch function.So when directive returns a URI it will be automatically set in onepic.Please specify any alternative solution or if Iam doing anything wrong ,Iam new to angularjs
推荐答案
试试这个..
在摄像头插件有一个 FileHelper.java 文件，替换插件 getRealPath 我的这种我的方法。
In Camera Plugin there is one FileHelper.java File, Replace the plugin getRealPath with my this my method.
有关详细信息，你可以按照这个 - > https://issues.apache.org / JIRA /浏览/ CB-5398
For more details you can follow this -> https://issues.apache.org/jira/browse/CB-5398
FileHelper.java
FileHelper.java
@SuppressWarnings("deprecation")
public static String getRealPath(String uriString, CordovaInterface cordova) {
String realPath = null;
final boolean isKitKat = Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT;
// DocumentProvider
if (isKitKat) {
Cursor cursor = cordova.getActivity().getContentResolver().query(Uri.parse(uriString), null, null, null, null);
cursor.moveToFirst();
String document_id = cursor.getString(0);
document_id = document_id.substring(document_id.lastIndexOf(":")+1);
cursor.close();
cursor = cordova.getActivity().getContentResolver().query(
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
null, MediaStore.Images.Media._ID + " = ? ", new String[]{document_id}, null);
cursor.moveToFirst();
String path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
realPath = path;
cursor.close();
}else{
if (uriString.startsWith("content://")) {
String[] proj = { _DATA };
Cursor cursor = cordova.getActivity().managedQuery(Uri.parse(uriString), proj, null, null, null);
int column_index = cursor.getColumnIndexOrThrow(_DATA);
cursor.moveToFirst();
realPath = cursor.getString(column_index);
if (realPath == null) {
LOG.e(LOG_TAG, "Could get real path for URI string %s", uriString);
}
} else if (uriString.startsWith("file://")) {
realPath = uriString.substring(7);
if (realPath.startsWith("/android_asset/")) {
LOG.e(LOG_TAG, "Cannot get real path for URI string %s because it is a file:///android_asset/ URI.", uriString);
realPath = null;
}
} else {
realPath = uriString;
}
}
return realPath;
}
在 CameraLauncher.java 类therer是一种方法 processResultFromGallery
In CameraLauncher.java Class therer is one method processResultFromGallery
private void processResultFromGallery
查找此code：
Find this code:
if (this.targetHeight == -1 && this.targetWidth == -1 &&
(destType == FILE_URI || destType == NATIVE_URI) && !this.correctOrientation){
this.callbackContext.success(uri.toString());
}
和替换这样的：
if (this.targetHeight == -1 && this.targetWidth == -1 &&
(destType == FILE_URI || destType == NATIVE_URI) && !this.correctOrientation) {
String s =FileHelper.getRealPath(uri.toString(), cordova);
Log.i("test","<<<<ifURI::::::"+s +"URI::::" + uri.toString());
this.callbackContext.success(s);
}
