Android :: Want To Create A ListView Activity With An Image In Every Row
May 5, 2010
I have been trying to create a ListView Activity with an ImageView in every row. I've used this tutorial: http://developer.android.com/resources/samples/ApiDemos/src/com/examp... The issue is that there are always some dividers missing whenever I run the example. The dividers are disappearing/appearing and flickering as i scroll the list (tested in emulator and HTC Tattoo). Strange is that the same example downloaded from the market (API Demos app) behaves correctly. Here is a screenshot of how it looks: http://yfrog.com/4cnokp.

I have a ListView that uses Linkify to create a link to another activity in my app. the url looks something like content://com.myapp/activitiy/view?param=blah
This works fine every time.
However, in another view, I'm trying to call some code like this:
CODE:.............
But for some reason this doesn't seem to work. It doesn't trigger my activity (and in fact it blows up if i dont include the setAction() call. How am I supposed to create the Intent such that it acts the same way that Linkify does...?
Now i realize i can setup the extras and then handle it in the activity, but that just seems like duplicated effort.

I am very new to Android (and Java) originally a C# developer.. and am struggling with the concepts and terminology.
I have been through almost all the tutorials and have decided to start on my first test app.The first part of my app is going to involve using the gallery widget (based on the hello gallery tutorial) to display a load of images. (these images will eventually come from the phones camera, but I will cross that bridge later!) My images are currently stored in the drawable folder in my project.As a first step I want to just have the user click on an image and it pops up full screen, just so I know how to get reference to it, but I am struggling. Evetually I want the user to click an image, then a window/activity(?) will open asking them for a bit of text. This will then be store in sqllite against the image. Code...

When a TabWidget is using intents to designate the target Activity for each tab, is there any special handling of those Activities on the Activity Stack outside of the default operation? For Instance, if my app has tabs A, B, and C, and I click them in this order--A, B, A, C, A, B--how will the Activity stack change? My understanding of the default operation, if startActivity() is called each time on the intent, would have the Stack keep loading up new instances of the activities: A, AB, ABA, ABAC, ABACA, ABACAB It's hard to believe that's how it works though... Seems like it would be a waste of resources and could be endless. Can anyone tell me how this will actually work?

I am working on developing an app and I am not sure when should I use a new activity and when should I update the existing view.
For example, lets say I have a view that shows a multiple choice question.Now, when the user selects his choices and clicks on say "Evaluate", I want to show the same question view but along with the right answers and explanations for each option. So does that mean, I should send an Intent upon a click on Evaluate or I should just update the view (i am not sure how)?
If I send an intent and show a new screen, how can the user go back to the next question without displaying the answers? If I don't create an new activity, how can I update the existing view that is already displayed?

I'd like to create a list with an image on the right side of each entry - and preferably have a separate callback if the image is clicked.
much like the contact call-listview - can click on either the name (edit) or the phone icon on the right (call).
just wondering what kind of list and/or adapter i have to use.

How do I create categories in an arbitrary ListView like those in Preferences (PreferenceCategory)?
I've found android.R.layout.preference_category that renders that grey TextView but don't see it mentioned anywhere from java code.

Just have a look in the system app contacts --->add new contact, this activity have a listview with different structured views for each row. I could do this by override the "getView" method, but a problem I'm facing is edittext will lose focus when I click on it. What happened when the view enter touch mode?

I want to create a customized ListView (or similar) which will behave like a closed (circular) one:
scrolling down - after the last item was reached the first begins (.., n-1, n, 1, 2, ..)
scrolling upward - after the first item was reached the last begins (.., 2, 1, n, n-1, ..)
It sounds simple conceptually but, apparently, there is no straightforward approach to do this.
I have already received an answer (from Streets Of Boston on Android-Developers google groups), but it sounds somehow ugly :) -
I did this by creating my own list-adapter (subclassed from BaseAdapter).
I coded my own list-adapter in such a way that its getCount() method returns a HUGE number.
And if item 'x' is selected, then this item corresponds to adapter position='adapter.getCount()/2+x'
And for my adapter's method getItem(int position), i look in my array that backs up the adapter and fetch the item on index:(position-getCount()/2) % myDataItems.length
You need to do some more 'special'stuff to make it all work correctly, but you get the idea.
In principle, it is still possible to reach the end or the beginning of the list, but if you set getCount() to around a million or so, this is hard to do :-)

I want to create a better NumberPicker then the one used in DatePicker, I looked at the HTC Sense Alarm clock Roller (Looks like the iPhone Spinner/Roller). I want to create something like that.
I've created a listView that looks right, but I need a way to get the current id of the middle row. ListView.getFirstVisiblePosition() kind of do what I want but it will give me +-1 errors. Another problem is that the scrolling should lock into a certain row when "dying" out. These are of couse related and I hope I can solve this by using a custom ListView, but it's hid in the API
Any thoughts on how to solve this?

I have a ListView with a lot of "rows". In each row, i have one TextView with a background image. When i scroll, the images of the rows mixes... they jump to another row with the scroll.
In have tried android: scrollingCache="false" and android:cacheColorHint="#00000000" but nothing.
The images are loaded dinamically.
Part of my layout:
CODE:.........................
And part of my code:
CODE:............
"avatars" is a cache of Drawables. any idea?
