Android : Way To Use A Gallery To Swipe Between Views?
Jul 15, 2010
I am following the Android Gallery tutorial (http://developer.android.com/guide/tutorials/views/hello-gallery.html) but instead of simple images I'd like to be able to horizontally move to a complete new screen, e.g. a LinearLayout. The idea is a kind of tabbing behaviour but the user can swipe though the screens. I created a gallery, created a GalleryAdapter that extends from BaseAdapter and in the getItem() method I try to return the complex view..

Ok, so recently (out of the blue) I went into the gallery on my Android and all the thumbnails were a plain image with a padlock. When I open images, I can view them individually but I cannot swipe to different images. I have no third party applications installed..

I am using the Hello Gallery code as an example. Views are not being recycled as I scroll left and right.
I added log output at the getView method, and I get a constant output of null. Anyone know the reason why?
Here is the code...

I have four images in the Gallery View. When we do swipe from left to right or right to left the Gallery View moves all the images i.e if I swipe from left to right from the first image then it will move to all the four images. What I want is that when I swipe it should only move to the next image.

Update: According to posters below it doesn't work on their fascinate. You can control the screen brightness, by swiping right or left, up where the notification bar is. if it doesn't work, try turning off power saving mode. settings>sound and display>power saving mode uncheck

I have a simple ListView and on that ListView I have placed a number of custom defined Views. The CustomView has ImageView and two TextViews.
The CustomView also has a "stateful drawable" as background, so that the background image (a 9-patch) changes if you press the Row in the ListView. When pressing the Row, the background image changes to a Red-ish thing.
The problem is that when the background changes from the default greyish, all the Views in the CustomView (ImageView and TextViews) still have their greyish background and thus creates very ugly greay boxes on top of the now redish background.
What is the best way to solve that problem? I hoped that such things were handled automatically (as it is done in for example .NET), but I was wrong it seems.

I am implementing a music player application in Android. My play list selection screen is implemented as a tab selector widget which contains a ListActivity inside each of the tabs: Artist, Albums, Songs.
I want to update the ListView in each of the ListActivity when I delete an item from any of the lists.
i.e. When I long press an item in the Artists list a context menu is drawn with "Delete Artist"
And it should delete all the songs from this artist in the Songs ListView, delete all the albums by this artist in the Albums ListView, and finally delete the entry for the artist in the Artist ListView.
Each of the ListActivity has its own fillData() method, which updates the ListView when the button in the context menu is pressed.
How can I call the fillData() method of the Albums ListActivity after I update the ListView inside of the Artists ListActivity?

I want to populate a table, defined in layout xml file through the programmatic way. I have define Table with a single row defining its header, with all the attributes set. Now i want to know a way so that i can just replicate that header row in the table with new content.
I tried using inflator inflate(int,view) method, but at runtime it showed up with error.
Here is the XML code for the layout file defining the table
CODE:.................

I have the following XML code:.................
The idea is to change the views, whenever I press one of the radio buttons. When I press a button the first time everything works out fine, but the second time I press a button, I get an IllegalStateException, and I can't quite see why I'm getting this.
Also, the Activity seems to set all my global variables to null, which is why I have to create them every time I switch from portrait to landscape or vice versa. So I would like to know if there is a way I can save my views in the Bundle, or any other way in which I can permanently save my views, so I don't have to add or create them every time, I flip the phone. And whenever I flip the phone, it seems that it rereads the main XML file, causing the RadioGroup to be set to 2D even if the 3D button is checked. This is because I've said the 2D button to be checked from when the app is first created, but I would like to also save the state of that RadioGroup.

How do you align views relative to the "middle" part of another view? I think it is best explained with a pic of the UI I'm trying to create in android.

Is there any way to query a root view of an activity for all of its child views even before the root view or its children have been inflated? I guess what I'm looking for is whether a view knows ahead of time what children it will have before it gets inflated, and can I get that list in some way. Bizarre I realize, but I think it will help me with some unconventional automation testing I'm working on. I haven't found anything in the API like this.

Let's say I have a LinearLayout, and I want to add a View to it, in my program from the Java code. What method is used for this? I'm not asking how it's done in XML, which I do know, but rather, how can I do something along the lines of (One View).add(Another View) Like one can do in Swing.

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.

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 was wondering if it would be possible to make an shortcut app that runs in the background to simulate a home, or back button press... Maybe with a two finger swipe or something. I have the Droid X, and the only thing I don't like is the hard buttons.

I'm pretty new to Android app development, and I've been playing around with swipe gestures using Android's SimpleOnGestureListener and a ViewFlipper.There are 3 children of the ViewFlipper, and each is a ScrollView. They're all dynamically populated when the Activity loads, and they don't change after that. The ScrollView is where the SimpleOnGestureListeners are attached.When I swipe on a page that scrolls, I get something full of "in onClick" "in onScroll" "in onFling" etc.On a page that's too short to scroll, I get "in onClick" "in onShowPress" "in onLongPress", and that's only if I'm touching the content within the too-short scrollview's children--if I touch elsewhere I get no events at all.Ideas on what's wrong, or how to detect the swipe gesture no matter how big the ScrollView is?

If (in Android) you wanted to write an alarm app where the user entered in the time for the alarm by swiping the hours & minutes up and down, what's the easiest way of achieving this? Is it the Swipe or Fling command?
Are there any good tutorials out there for this?

I'm totally new to this, been tinkering around for a week.
Came up with a simple image viewer app for 2 images.
Feature:
Left and right swipes will switch the images. Dead simple.
What i'd like to do:
Have up to 100 images.
note:
All my images are in my res/drawable folder.
They're named image1.png to image100.png
I obviously don't want to do:
ImageView i = new ImageView(this);
i.setImageResource(R.drawable.image1);
viewFlipper.addView(i);
ImageView i2 = new ImageView(this);
i2.setImageResource(R.drawable.image2);
viewFlipper.addView(i2);
ImageView i3 = new ImageView(this);
i3.setImageResource(R.drawable.image3);
viewFlipper.addView(i3);
all the way to i100. how do I make this into a loop, which is flexible and reads everything from the drawable folder ( and not be limited to 100 images)?
source: Code...

Wondering here if there is a way I could trigger an event, so that any library listening for these events (e.g. jQTouch, Sencha touch, iUI, ... ).
If I could extend or use jQuery for such task e.g. $(...).trigger('event') that would be great to know.
Usage example:
I need to debug a few web apps by simulating multi touch with my mouse. This seems a little complicated, so if I could trigger the multi-touch events using Javascript I could therefore test the app more efficiently.

Is it possible to detect that the viewport is being dragged by a touch event?
Using the following code I am able to get the position of where the finger touched the screen, what node started the event and where it was dragged to. Which solves one of the problems but I would really like to detect when the user has dragged the page/window/viewport down.
To attempt to be more clear as to what I am trying to do: I would like simulate the refresh activity in Tweetie 2/Twitter for iPhone but in HTML5 and JavaScript. Code....
