Android 4.3 crop gallery resultCode Cancel

阅读更多关于 Android 4.3 crop gallery resultCode Cancel

My Galaxy Nexus is now running on Android 4.3 allowing me to test my application with this new version. Everything seems fine except cropping. I have an application that uses the camera to take picture and then crop the image through the gallery app. I am also able to choose a picture from the gallery and crop it after. Since Android 4.3, the gallery application changed.

阅读更多关于 Android: How to query a list of bucket name

I want to retrieve only the name of the bucket (Albums). E.g. Camera, Download etc but not a list of Camera, Download etc from all the the photos so how do I retrieve one row each for each bucket name? What I mean like in Gallery Application, you have albums first e.g. Camera. When you clicked on it, it show all the photos of the camera. I can query the photos in a Camera Roll with the Where clause of the query. But what if I wanted only the name of each of the albums' name and not the photos, is it possible to query that? If I query all the photos and take only one row per set of photos, then

问题 I'm trying to make a little app that displays only images from a specific folder in a gallery view. I have found a few examples, but every single one just ends up displaying only 1 image.

I have just received the following design for a project, for an image grid gallery, with dynamic width & height images (user submitted images).
