I am using this following code which creates a ListView with text and an icon but the problem that I have which the following I want the array to be dynamic instead of static so my list gets created dynamically not statistically. My ultimate goal is to retrieve specific strings from my Db and to display it then on the Listview where every string would be in each row.

I have Eclipse Juno and I'm working on an app with that.
The main activity will have a scrollable menu that takes you to all the other activities.
So the general structure/outline right now:[HIGH]Relative Layout ImageView (header logo type thing) ListView (the actual scrollable menu)[/HIGH]Here's the problem though... I can't find any simple list tutorials. I can easily make a single line list work but I need to make a two line list and one that is static, not dynamic and no examples are out there for that. It's like if you want to make a 2 line list, you can only learn how to do it in the most code-heavy ridiculous way possible.
Essentially what I am looking for with the list is this: Item one: Centred, bold, non selectable title (Resources)
- Item two-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.
- Item ??: Centred, bold, non selectable title (Tools)
- Item ??-??: two line list items, click-able to a new activity, title of the section on first line, description on the second line.
Nothing dynamic that is ever going to change, no super complex wonkey calculations, just to simply have the data set in stone (preferably via XML) and to call it into the list.
I experimented with some of the other list views and no matter what I did, I could get, via editing the resources and NOT using Java, more that one item on a single line but it wouldn't format it properly according to the layout I guess because I haven't got the ID correct or whatever I don't know.
I mean, all the examples I've seen for a 2 line list are extraordinarily over-coded and just bloated. I mean I have a website I am still working on in C#/ASP.net that has far more complex things in it with half the code that I've seen for the examples of the two line lists.
I tried on my own to figure it out (I am decent with C# and vaguely familiar with Java, self taught, and programming for some other systems like Python, again all self-taught), but like ALL coding references, they're organised by the actual code you implement (that you don't know) instead of by what you want it to do (so you have to search the whole code base to find something that you don't know what it's called but know what it does). >:C
how to load dynamic array from vector in android?
View 1 Replies View RelatedI have created a broadcast receiver statically by specifying it within the Manifest, and I have also created the "same" broadcast receiver in code and have registered it with the application context. The static way works very well, but the dynamic way does not receive the expected broadcast. It could be that I am not creating the intent filter correctly, or that I need to register it with some other context somewhere. Please see the code examples to see what I am doing. This is related to receiving data SMS, it works very well on a device using a broadcast receiver defined in the Manifest. The correct permissions are set for both examples.
The following is from the Manifest, and the resulting receiver gets the expected broadcasts:
CODE:.....
The following is the code example that doesn't work (it does work with an intent like "android.provider.Telephony.SMS_RECEIVED" but not for data sms):
CODE:.....
The question is - why does this broadcast receiver get notified of the incoming data messages? It seems some other resource is notified when the Manifest version of the receiver is created...
I need compiling a lib (ODE) for android - problem is it uses automake and I can't seem to find any decent documentation/how to cross compile a static/dynamic lib for android.
BTW, I'm using ubuntu 12.04 as a dev environment (latest up-to-datest SDK and NDKs are installed) and I have no problem with making the wrapper library - just need to get the static (or dynamic) lib built.

View 1 Replies View RelatedI have a ListView with several columns and I need a header row at the very top that labels each of these columns that *does not* scroll with the rest of the ListView. I am using addHeaderView right now, but I've ran into 2 problems:
1) The header scrolls. I need it outside of scrolling so that it's always "floating" on top.
2) Each column in the header isn't lining up with the columns in the listview. I can make the header columns and data columns all line up perfectly if they're all in one big TableLayout, but how would I get the header to be outside of the scrollview yet also stay uniform and inline with the data columns?
In my application, I am going to create a few listviews that are dependent on the listview before it. For example,Then, depending on user choice, will go next screen, let's say, it contains a submenu of each type of school,that may be different or may be the same to other states.What I want to know, is how to populate these different lists dynamically as the user goes on? I don't know what the best of doing this is, and I seem to be looking in the all the wrong places because I keep getting stuck. Once all the data is added into whatever structure is used, it will be static. I basically just need help as to how to code information into some sort of hashtable or anything of the sort that can be easily referenced, and later when the Application is updated, be able to add more schools/states/submenus etc.

I am making a time sheet program where a user inputs his in- and out-punches. I have a ListView that I am populating from an array of calendar objects. I would like each row to show the day and date then on a new line the time, but I only want to display the day and date if it is different from the previous element.Currently, I am setting visibility in the Base Adapter based on comparisons using position vs position-1 (which are used as indices to the array). This only works if the whole list fits on the screen. If it extends beyond the screen and the user scrolls around the results are unpredictable.To further confuse things, I am setting the color of the times, based on the position, to alternate between green and red (in/out) and it works as expected, scrolling or not.How does Android handle the ListView position when scrolling or what could I do differently to show/hide the day and date? Code...

View 1 Replies View RelatedI'm trying to get my first Android app stable enough for the marketplace, and I've hit a brick wall with one exception that I don't understand. Probably I'm doing something stupid, but I can't tell what, and after several hours googling and experimenting, I thought I'd see if I can get some help. My Activity extends ListActivity, and the parts I think are most important are extracted below:
GroupedListAdapter is a simple class that extends BasedAdapter to provide headings for sections of the list (not unlike the Fancy ListView tutorials that are floating around).
I create this in onCreate, and it works fine. Inside onListItemClick, I do some actions which will create a different set of list contents. I "clear" the adapter, which empties the contents, and call reload, which repopulates it. Then I call notifyDataSetChanged.
Most often, this seems to work, but also fairly often, I get the exception following the code snippets below - this seems to indicate the ListView is not in sync with my changes. Lately this crash happens 100% of the time under the simulator.

Can any one tell me how to achieve this?
I must be missing something simple here.I've searched around but don't think my search query is touching on the right topics to yield results. Anyhow, what I'm after is running through the array of data I bind to a ListView after a "Submit" button has been clicked.

It only uses a small part of the screen (about 2 lines per list), instead of filling the available height, and the lists themselves can be scrolled. How can I change the layout to always show the whole lists but have the screen be scrollalbe?

View 1 Replies View RelatedI have a ListView with a scrolling issue. The Array contain a large number of items. When I try to scroll down, the listview displays the first items again. For example, if the initial view shows 12 items and I scroll down to view the next three, instead of showing 4 through 15, if shows 4 through 12 followed by 1, 2, and three. Debugging the Adapter reports that getView return 4 through 15 just as I would expect.

View 3 Replies View RelatedI have some problems when creating a ListActivity.
I have a listview and some other widgets and my listview is filled with a custom adapter.
You can see the images of this activity here:

Now the problem is. I have a scrollview and all the other views and widgets are placed inside of it. As you can see on the image, I don't see all of my 6 comments (that is the list). When i don't place the scrollview the height of the list is perfect (i have set android:layout_height to wrap_content (to my listview and parent LinearLayout). This is perfect but I have other widgets under the list and when the list reaches the bottom of the screen I can't to scroll to view my other widgets..
How can I fix this? I can set the height of the linearlayout manually but the problem is that the height doesnt has to be the same all the time (it loads the commens from my web service).. It has to fit the height of all the comments (like wrap_content normally does..)
Here is a part of the code with the layout and listview..
