[英]Appcelerator - Android open image galley
當打開圖片庫時,應用程序有時會崩潰,而有時不會。 它顯示一個Java異常,但沒有有意義的消息。
有人有主意嗎? 我也使用了意圖,但無法使其正常工作。
謝謝!
這是我的代碼示例:
Here a sample of my code:
function openGallery() {
var popoverView;
var arrowDirection;
if(Titanium.Platform.osname == 'ipad') {
// photogallery displays in a popover on the ipad and we
// want to make it relative to our image with a left arrow
arrowDirection = Ti.UI.iPad.POPOVER_ARROW_DIRECTION_LEFT;
popoverView = imageView;
}
var image = undefined;
Titanium.Media.openPhotoGallery({
success : function(event) {
var cropRect = event.cropRect;
image = event.media;
// set image view
Ti.API.debug('Our type was: ' + event.mediaType);
if(event.mediaType == Ti.Media.MEDIA_TYPE_PHOTO) {
addAttachment(image);
} else {
// is this necessary?
}
},
cancel : function() {
},
error : function(error) {
},
allowEditing : true,
saveToPhotoGallery : true,
popoverView : popoverView,
arrowDirection : arrowDirection,
mediaTypes : [Ti.Media.MEDIA_TYPE_VIDEO, Ti.Media.MEDIA_TYPE_PHOTO]
});
}
var win = Titanium.UI.createWindow({
title:"Accessing the photo album",
backgroundColor:"#FFFFFF",
exitOnClose:true
});
var button = Titanium.UI.createButton({
title:"Open the photo gallery",
width:180,
height:48,
bottom: 12,
zIndex:2
});
button.addEventListener("click", function(e){
//Open the photo gallery
Titanium.Media.openPhotoGallery({
//function to call upon successful load of the gallery
success:function(e){
//e.media represents the photo or video
var imageView = Titanium.UI.createImageView({
image:e.media,
width:320,
height:480,
top:12,
zIndex:1
});
win.add(imageView);
},
error:function(e){
alert("There was an error");
},
cancel:function(e){
alert("The photo gallery was cancelled");
},
//Allow editing of media before success
allowEditing:true,
//Media types to allow
mediaTypes:[Ti.Media.MEDIA_TYPE_PHOTO]
//The other is Titanium.Media.MEDIA_TYPE_VIDEO
});
});
win.add(button);
win.open();
當我從項目切換時,上述評論從未解決過這個問題。
