Android: lazy loading in Gallery

泄露秘密 提交于 2019-11-30 08:44:15
问题 I've reviewed some posts about lazy loading but I believe my problem is a bit different. I have a gallery (my class extends Gallery) which displays 20 rather large in size images (400-500K each). I cannot load them all to gallery since I get an OutOfMemory exception. So, I created an array of 20 Drawables and initially populated the first 9 elements (the images come from the Web) and set all the rest to null. My intention was this: on a fling to the right, fetch element no. 10 and set to null

Now I thinking of providing different view holders for different cases in the

I want them to be centered, both horizontally

get the path of a Gallery Folder in Android

陌路散爱 提交于 2019-11-29 07:08:24
I know how to programatically get a gallery image (one by one). Now that the gallery is organised folderwise Is there a way to select and get the path of a folder in the gallery view... You can get path here but MediaScanner will find every folder on SDCARD with photos. final String path = android.os.Environment.DIRECTORY_DCIM; With this method you can get the path of the Gallery of your device: private static String getGalleryPath() { return photoDir = Environment.getExternalStorageDirectory() + "/" + Environment.DIRECTORY_DCIM + "/"; } rayworks String getGalleryPath() { File folder =
