Does a replacement for Gallery widget with View recycling exist?

问题 The default Gallery widget on Android does not recycle views - everytime the view for a new position is called the widget always calls the getView method of the adapter with convertView set to null. As you scroll backwards and forwards this ends up in lots of views being created, which the recycler component that the Gallery stores them in does not seem to recycle them quickly enough leading to an OOM situation. You can test this easily with a few large-ish images as your gallery items, but

How to implement an endless gallery in Android?

问题 I am using a gallery layout in my application. It is working when the user moves the pictures in the gallery from left to right (it is infinite that means elements are repeated again). But when the user moves from right to left and reaches the first element, it doesn't. After then no elements are coming. But I want to repeat elements from this side also. Can you give me some suggestions? Gallery g = (Gallery) findViewById(R.id.gallery); g.setAdapter(new ImageAdapter(this)); g.setFocusable

List all camera images in Android

How do you get a list of all camera images of an Android device? Is it through the MediaStore? How? The Gallery app obtains camera images by using a content resolver over Images.Media.EXTERNAL_CONTENT_URI and filtering the results by Media.BUCKET_ID . The bucket identifier is determined with the following code: public static final String CAMERA_IMAGE_BUCKET_NAME = Environment.getExternalStorageDirectory().toString() + "/DCIM/Camera"; public static final String CAMERA_IMAGE_BUCKET_ID = getBucketId(CAMERA_IMAGE_BUCKET_NAME); /** * Matches code in MediaProvider.computeBucketValues. Should be a

Possible Duplicate: Horizontal ListView in Android? Like many things in Android, you wouldn't think this would be such a hard problem but ohhh, by golly, would you be wrong. And, like many things in Android, the API doesn't even provide a reasonably extensible starting point. I'll be damned if I'm going to roll my own ListView, when all I want is to take the thing and turn it on its side. \rant Okay, now that I'm done fuming, let's talk about the problem itself. What I need is basically something exactly like the Gallery , but without the center-locking feature. I don't really need ListView 's

jquery move elements into a random order

由 一笑奈何 提交于 2019-11-26 14:05:53
问题 I am attempting to display a series of images in a random order. However, I do not want any single item to repeat until all items have been shown, so instead of selecting a random image from the array, I want to take the entire array, randomize it, and then select in sequence from the first to the last element. Here's my code: HTML: <div id="tout4" <img src="images/gallery01.jpg" class="img_lg"/> <img src="images/gallery02.jpg" class="img_lg"/> <img src="images/gallery03.jpg" class="img_lg"/>
