Android :: Android Gallery - How To Detect Item Which Shifted In Gallery?
Jul 7, 2010
I am using a Gallery based Coverflow, as suggested here.Is there an event that can be caught, which indicates that a single shift (either left or right) has been made in my gallery/cover flow? To be clear, if I gave the gallery a decent swipe and my center (selected) image has changed 8 times, I would like to catch this event 8 times. OnFling() just indicates a single swipe - regardless how many items have shifted.Getting getSelectedItemPosition() before and after the swipe doesn't help since I need to do some work on every shift.It will also be nice while I am at it, to get the direction of the shift - either right or left.

I have a Gallery with a set of images that was downloaded at run time.I followed the example here:http://www.anddev.org/a_androidwidgetgallery_-_example-t332.html but instead of using i.setImageResource(this.myImageIds[position]);I used i.setImageBitmap(bitmaps.get(position));This doesn't fill the entire width of the screen, only as much as the width specified here:i.setLayoutParams(new Gallery.LayoutParams(150, 150)); When I increase this number, the item scales with it instead of showing more images per the example. I've even tried to scale the images before adding them to the set. Not sure what I'm missing, or where other examples of this might be. Any help would be great.

The default gallery widget only provides events for when items are clicked, but is there any way to tell what item is selected when only dragging the gallery around?

I have a gallery that displays TextViews where the background of each view is the following code...
This selector work just fine for the state_pressed and default (idle) states, but the selected item state is never displayed. I REALLY do not want to force the background of the selected item by changing the background of the view when the onItemSelected event is called. What is the correct state or correct way to get the TextView background to be set properly. Is the selected (center) view in the gallery not really selected? Is there some other state I should put in the selector drawable xml?

I am currently using a modified Gallery widget to display real-time events coverflow-style. What I now need is some Method to scroll to a specific item within the Gallery. Such method IS available within frameworks/base/core/java/android/ widget/Gallery.java as scrollToChild but is declared as private. Do you know of any manual way to move/scroll around a Gallery / List Widget?
Current workaround would be to inject DPAD_RIGHT using the Instrumentation Framework, which is as really ugly solution.

I'm trying to set the selection of a Gallery in code. I would like to have the Gallery smoothly roll down a few items over the duration of a second or two. At frist glance, it appears that two members would to the trick:Gallery.setAnimationDuration(int animationDurationMillis); Gallery.setSelection(int position, boolean animate); It turns out that the setAnimationDuration only seems to affect the rubber-bandy "return-to-center" effect of the Gallery. In other words, when a gallery comes to rest after a fling, and a gallery item is off center, the animationDurationMillis is used to control the duration of the Gallery centering up the item. However, the value seems to have no effect on the setSelection. No matter what value is set with setAnimationDuration, the Gallery seems to render about 2 or 3 frames when flying between items 1 and 10 for example. Is this working as designed? Does anyone know a trick or workaround that would let me properly animate setSelection? I'd be especially grateful if we could do it with an "Ease Out" effect.

Every image and video in the stock Android ICS Gallery app is displayed twice, how can I fix this?
This only happened a couple of days ago. I know the items themselves are not duplicated because I've checked with QuickPic, Root Explorer and Windows Explorer.
I have a Nexus S running a rooted build of stock 4.0.4. I've tried clearing cache and data of the gallery app to no avail.
SOLUTION: Go to Settings > Apps > All. Find Media Storage and then Clear Data. Reboot the phone (I had to do it twice) and it will clear your thumbnails, recreate them and put everything back to normal.

I have an activity with a ListView check list and a spinner that controls the sort order of the items in that check list. One of the sort options is to move the checked items to the beginning of the list. I would like to allow users to check some items in the list, select the 'sort by checks' option, check some more items in the list, and select the 'sort by checks' option again. However, I don't see how to detect that second selection of the spinner's 'sort by checks' option.
I've tried using setOnItemSelectedListener, but it doesn't call the onItemSelected handler unless a different item is selected. And I've tried using setOnItemClickListener, but it seems that listener cannot be used with a spinner according to following run-time exception from logcat:
- - - D/AndroidRuntime( 987): Shutting down VM W/dalvikvm( 987): threadid=3: thread exiting with uncaught exception (group=0x4000fe70) E/AndroidRuntime( 987): Uncaught handler: thread main exiting due to uncaught exception E/AndroidRuntime( 987): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.test.spinner/com.test.spinner.check_list}: java.lang.RuntimeException: setOnItemClickListener cannot be used with a spinner. E/AndroidRuntime( 987): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java: 2268) - - -
Any tips on how to detect the selection of an already selected item in a spinner?

I have a gallery and when a image is selected, I want to start new thread (for loading other images). But I don't want to do it while the gallery is scrolling. How can I know the state of the gallery and if it is still scrolling? I can't use "setCallbackDuringFling(false)" because I have a textview under the image that has to be updated during the scrolling.

I've got the Nexus One and the gallery app on it is awful. You can't move your photos between albums or rename them unless you go into the SD card and do it and even then you have to turn the phone off and on again before the changes show in the gallery.Does anyone else have this problem and how do you put up with it? Is there an app (ideally free) that lets you view your photos, rename them and move them around albums etc? Its a basic thing that all the older phones can do so why is a supposed smart phone so rubbish at it!

I have a Droid just running stock 2.0.1. What I am looking for is a photo/picture gallery app that simply let's you select the folders that you want to display in the app. I was fine with the stock gallery for awhile, but then I started getting a variety of apps that store pictures in various folders (the worst one being Touchdown for Exchange which puts almost every attachment in a new folder). The stock gallery now takes forever to load up, as it is loading a TON of folders with images in them. Really it makes it almost useless at this point. This was the main reason I switched to MixZing for audio, as it let me narrow my library down to the few folders that actually mattered.

I am simply trying to get the path of an image that the user selects and then convert it into a bitmap. The problem is, only some of the images in the gallery work when selected (by "work" I mean they are found to be a file that exists), while the others claim the file does not exist (even though the image is showing up in the gallery?). Even more strange is that this doesn't seem to be consistent, an image that was at one point considered to "exist" now claims to be nonexistent..............

I'm using the blow code to open the gallery and grab an image for an incon im gong to store in a database and access later to populate a listview attached to a simpleCursorAdapter...........
The code runs, and then starts force closing (what seems like) randomly. I'm convinced that I've gotten something confused somewhere but since the force closure happens at all different points of my app I dont know where to start looking.

As per title - there are options to delete jpg, but not gif. In order to delete the latter the only way is to connect the phone to pc and delete them directly from SD card. But not from the gallery. Is it a bug?

I really like things organized on my Samsung Captivate. I have folders in my Gallery listed by date and all is good except....
Is there a way to NOT have videos and movies in the Gallery?
Also, when I download pics from emails and whatever, they end up by themselves in the Gallery. Can I auto save them to a special folder or something?

I am working on a application, in which I want to show Image gallery containing full screen images. I have put the gallery in the application successfully. But I am failing to apply some properties to the gallery as per the app design demands. I am using android.widget.Gallery library of android. The things I am failing to do are:
1) I wanna scroll the gallery images one at a time, as now its getting scrolled more than one images in one scroll.
2) And on scrolling the gallery, the images coming next from left/ right should move smothly into the screen and should stop at the screen edges. It should not scroll beyong that in one scroll.

I have a listview that has a photograph from the gallery for each entry but it was blowing up and running out of memory so I resized the image
BitmapFactory.Options opts = new BitmapFactory.Options();
opts.inSampleSize = 8;
Bitmap yourSelectedImage = BitmapFactory.decodeFile(photo,opts);
imgView.setImageBitmap(yourSelectedImage);
The problem I have is that each image in the list has to be resized before it is displaying the view. Is there a way to link to the thumbnail view instead of the full size image so that I don't have to resize them or is there a way to load each picture as it is sized instead of having to wait for them all.
