Android :: Way To Refresh An Activity / Map View Refresh Fails?

May 3, 2010

After implementing some Android Apps, including several Map activities, I try to refresh the activity when the GPS listener's onLocationChanged() mehtod is called. I have no idea how to tell the map activity to refresh on its own and display the new coords. the coords to store will have to be in global values, so that the location listener will have access to it. In my sample GPS-class (see code below) I just changed the text of a text view....but how to do that in map view?

Android :: Manually / Programatically Scroll To A Specific Item In Gallery?

Apr 9, 2010

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.

Android :: Way To Refresh Gallery After Saving Photo In Droid?

Jun 7, 2010

I have an application where I want to have the ability for the user to save one of the photos they are viewing to their phone locally. I got saving working, and now I want to automatically refresh so they don't have to turn off their phone before it shows up in the gallery. I googled around and saw this: sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse(Environment.getExternalStorageDirectory().getAbsolutePath() ))); I tried doing that, but it didn't refresh for me. Does anyone have any ideas?

Android :: Broken Gallery View? Using Gallery Set Selection (int Position / Boolean Animate)

Feb 6, 2009

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.

Android :: Set A New View's Margins Programatically

Sep 4, 2010

I have a FrameView that's created in my XML layout, and in my code, I'm trying to create a series of new ImageViews and add them as children of this FrameView. The ImageViews are small, only about 15 pixels square, and I want them to show up in various positions around the FrameView (I'm trying to implement what looks like a radar screen). I'm able to create them and add them just fine, and they show up on the screen.

However, when I try to set their margins, it doesn't seem to have any effect. No matter what I set, all the ImageViews show up in the top left corner of the FrameView, as opposed to offset by the appropriate margins. My XML layout is listed below, along with the code that generates the child views. Am I doing something wrong? How can I get the margins to show up properly? Or is there a better way to do this than by using margins.

Android :: Adding Item To View Programatically?

Nov 8, 2010

I am trying to find out how I can add an item (from xml drawable/workaround_item.xml) in a LinearLayout that is vertically aligned.

CODE:.........

At the beggining I was trying to use a ListView but as far I as know there is a bug using listview inside a scrollview. I was doing this because i have more components on the view that should be scrolled together with the list view. So I decided to remove the listview and implement a simple linear layout where i will be adding each element bellow other and so on.

The layout for the activity is as folow (layout/workaround.xml) and i would like to start adding the elements below the top bar.

CODE:........

Thats my java code:

CODE:......

Thats the result i am getting: http://twitpic.com/3562yu

Does android allow us to do this? If so, Hoe can I add the elements and set their values? (this layout will be dispalying results of soccer games).

Android :: Gallery Child View

I have created a child class from the Gallery view, named MyGallery. I did this because I wanted to get rid of the onFling event in the gallery view. Having that achieved, it lead me to a different problem. Scrolling the Gallery with the Dpad doesn't work now. When I tried using the original Gallery class, the dpad works fine. But when I extend the Gallery and use my custom gallery class, the dpad stops working. Am I missing something?

HTC Incredible :: Slow To Load / View / Flick Gallery

Sep 15, 2010

Got the OTA like everyone else and everything works great. The ONLY thing I have realized is that my photo Gallery (the stock one) is running SOOO slow. I used to be able to flick through the photos without ever coming upon a grey square (with no pic). Now, after a strong flick, I get nothing but grey squares. They eventually load into pictures, but it takes about 3 - 4 seconds before they load. Any ideas? Could it be there are too many pics in the phone / card or is this as a result of the update?

Android :: Gallery / Adapter View Child Draw Able State

Oct 4, 2010

I am using a Gallery view where the view corresponding to each item is non-trivial and consists of text as well as multiple buttons. When I click to drag the gallery view (somewhere not on one of the buttons) the button's drawable state changes to pressed and appears as if all of the buttons are currently being pressed. Additionally, the same behavior happens for the selected state (e.g. all of the text of the child TextViews changes color). I am trying to prevent this behavior and have found the android:duplicateParentState xml attribute as well as the setDuplicateParentStateEnabled property. This seems like it should accomplish what I am trying to do, but it seems to have no effect.

Android : Database Vs Filesystem / Gallery App For Holding List View Of Pictures

Apr 13, 2010

I am new on android and building an application which uses webservice to collect user information in XML. I also get path for a small jpeg picture of each user. (Currently there are about 200 users) I am parsing the XML and storing the information in SQLiteDatabase. Pictures are stored as blob and able to retrieve them.

I display names of users on listview with images as well. But is this a good solution for storing pictures in SQLite Database ? or should consider storing it in file system ? Which is suitable in terms of performance , as well as memory and any other pro and cons on Android.

Also like to know which is best performing XML parser for Android ?

My purpose is only to parse xml files which I get through web services and sort out the data to store in storage. And lastly my memory goes off easily when I load all images to display in list view after making thumbnails of each (which is obvious).

Was wondering is there any library/framework/app available which dynamically loads images as and when required (when that list item is on display) something like Gallery program ?

HTC Droid Eris :: Nexus 3D Gallery Show Up As Grey Boxes / View It?

May 25, 2010

So I have the nexus 3D gallery app installed on my 2.1 Eris. It works fine other than it refuses to generate thumbnails sometimes. They just show up as grey boxes. Once it finally does generate the thumbnails, it's fine, but sometimes they just won't generate. For example, I took some pics this past Sunday and the thumbnails are still just showing up as grey boxes. It takes several cycles of closing gallery, opening gallery, closing, opening, etc. etc. to get it to finally generate all the thumbnails, then they're fine. Oh, and sometimes they don't show up at all. Seems this app is very buggy on the Eris.

HTC EVO 4G : "Camera Shots" - When I Opened Gallery To View A Picture

Nov 24, 2010

I have a few videos on my SD card. A couple that were downloaded but most have been recorded with the phone. I have all tha videos sorted into folders so I know which is which. But, today when I opened the gallery to view a picture there was a new folder created called "camera shots" with all the videos in it, or which I thought were the videos. When I opened the folder all the files were a picture of the beginning of each video and were shrunken down so small they are really hard to see. When I looked at the properties of each they all had the file ending in png. Anyone have any idea what png is and has anyone else had your phone recreate the "camera shots" folder without you taking any new pictures or videos?

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.
