Android :: Loading - Row At The End Of The List - During Data Download

Aug 1, 2010

I have got list that is filled with data from internet.

Datas are downloaded in chunks. At the end of the list next portion of data is downloaded and added to the list.

I'm detecting list end with help of onScrollListner:

CODE:........

I would like to addLoading... row when datas are being downloaded. Something similar to Gmail loading row at the end of the list.

I know that I can hack adapter.getCount() to return size + 1 and force adapter.getView to display loading... at the end of the list.

How can I do that in more elegant way?

Android :: Loading Google Maps Data Into Searchable Data Structure

Mar 2, 2010

For my CS bachelors I am doing a Senior project using android and google maps.My vision was to do a (relatively) simple Dijkstra shortest path using google maps road data. I was going to add elevation change along with 2D distance. I am doing well playing with maps in android but I am completely stumped trying to access google maps data in any sort of searchable form.How would I go about accessing the data for say intersections of roads (lat/long) in a particular area?There has to be a way to pull that data in some sort of tree form. It seems like it may be possible with kml?Any pointers would be awesome.I want my paths to follow roads but If i cant this is going to turn into an orienteering application fairly fast.

Android :: Advice On First Application (loading Data / Populating Data)

Jun 23, 2010

to start with I've gone through the entire notepad tutorial, I'm a professional game programmer who has some extra time. (though most of my time has been in C++, I did take a year or two of Java classes in college, and remember some of it). I'm not sure the site is a good site to ask questions like this.. If someone has a Forum that might be a good place to ask these newbie questions, please feel free to point me in the direction. I've examined a few of the samples, and think I've a grasp of what I want to do. I've a three to four project plan for some Android releases to sharpen my skills, but since this is my first project and I have never really developed for a mobile phone or the android before, I'd like to make sure I have a solid plan.The first project is an example of the license plate game, however I want to do a few things to change it. Heck maybe when I'm done it'll become a bingo style game, with bluetooth connectivity, you never know. The base idea is I want to offer a list of states, with checkboxes next to them. so to do this, I'll be starting with a Linear List layout similar to the note pad example, and then have a row that is only a Checkbox. I can use text and call strike through if it's been checked off. Perhaps offer an option to not show them if they are checked.

But I want the list to be generated from a set of lists. Maybe all of America's states, maybe reasonable American states (no Hawaii, no Alaska) maybe a North American list, (add in Mexico and some Canadian provinces), a European list, who knows. I'd probably have to have a pop up window that lists all of the lists I suppose using a radiogroup of some sort. So then as far as the data, after weighing options I think best solution is to make a database with two fields, "checked" and "name".I figure I can use the menu for most of the user interaction (aside from clicking on stuff we want to check off) with maybe a few context menu items, I understand how to make all of those already so I should be good. The question I have is what is the best way to populate the lists? Should I create raw data, and have different files for all the lists? Or is there some other way to do this? I've seen this done on the searchable dictionary, but I'd like to hear what people who have actually generated the data like this before. In addition is there an easy way to look at the sql database these applications create, or do you have to run searches on them and output the data? Finally any other suggestion or advice? I definitely want to try to get something like this on the market so I can see the full life cycle and see if anyone actually likes it. (luckily there's not a plethora of them already) but I also want a few people to look over my code if they're willing when I'm done to make sure I've done this right or at least not missing any basic mistakes.

Android :: Loading String Values From File Instead Of List In Class

Nov 1, 2010

I think I have a pretty easy problem to solve, but I have been beating my head against the wall for hours trying to get past it! I have an adapter that loads a list of URLS:
adapter=new MyAdapter(this, lStrings);
list.setAdapter(adapter);

The list of URLS looks like this:
private String[] lStrings={
"http://www.domain.com/file1.jpg",
"http://www.domain.com/file2.jpg",
"http://www.domain.com/file3.jpg",
};

What I want instead is to load these values from a text file that lies on the SD card. For that matter, I would be okay with loading the values from a text file into a String, and then load the String into the list as I imagine that would be the "cleaner approach". However, all attempts to do this have failed. For instance, I replaced the above snippet with this:

private String[] lStrings=
{ MainActivity.this.getString(R.string.myurllist) };
but then I get a Forced Close on loading.

I'm a bit new to Java, Android, and development in general.

Android :: Loading Dictionary For Input Method Suggestion List

May 11, 2010

For various reasons, i'm trying to write my own input keyboard. So far all is going well except that of creating the suggestions.

I've found the latinIME algorithm, which is all good.

However i'm having major difficulty working out how to load the dictionary in the first place.

I've had a good look round the net, and found various suggestions, but no definitive answers, and i cant seem to get any of them to work.

If anyone has any suggestions on how best to do it, or even better some sample code, that would be brilliant.

Android :: Loading A Large List Of Contacts Into A ListAdapter - Making It Responsive

Jan 23, 2009

I need to load Contacts.Phones.CONTENT_URI and Contacts.ContactMethods.CONTENT_EMAIL_URI into a ListActivity.

Since these are separate Content URIs, I have two separate cursors and can't construct a SimpleCursorAdapter for use in the ListActivity.

The problem is that I have more than a thousand records for CONTENT_EMAIL_URI, which were automatically loaded by GMail. The app becomes unresponsive and Android prompts to kill the app or wait.

Is there a way to make the ListActivity content load in the background, like, by writing a custom implementation of android.widget.Adapter?

Or is it more feasible to use a single cursor, by manually running the SQL query on the contacts tables?

Android :: Way Of Loading Data / Notifying An Activity?

Oct 8, 2009

I just tried a stupid approach and it crashed my app... Basically I have an activity that has three tabs (containing three activities). Each of the tabs gets its input from an xml file downloaded off the net. Everything is fine but when I start my app, it has download the xml file and there's a "wait" time for this.I managed to get around this by adding a splash screen. It looks beautiful but the problem is when I click on the second tab, it still has to get the list off the net, so it looks ugly now... It waits before displaying the list. So what I did was design an AsyncTask that just downloads the xml file. In my main activity, I spawn two tasks initially and send the URL and Intent as parameters. And inside the activities that start inside the tabs, I use a wait(). Inside the AsyncTask, after it is done with the download, I notify the Intent using notify(). This crashed! Of course, I didn't expect it to work but just wanted to try :) Writing it so that I can either get a feedback as to why this failed or to prevent others from wasting their time on this...Now, I am sure many face the problem of a "wait" time inside the tabs. How do I solve this? I am thinking of either dimming the screen and then displaying a series of toasts or display a progress indicator inside the tabs or pre-fetching the xml files... I don't have a clue on how these can be achieved.

Android :: Loading New Data With Back Button

Apr 10, 2009

I have a message application so that on view 1 is displayed a list of messages and when you go to view 2 (subactivity) you can send a message. I want the program to work so that when you hit the android back button, you can go back to view 1 and see the list of messages including the new message. Right now only the old data is displayed, and I noticed that displayContent() is not called when going back which I assumed it would. Is there any way to specify that when the back button is hit, to call displayContent() again on the previous activity?

Android :: Loading Data Asynchronously While Displaying GUI

My application needs to load and process some data at the startup which delays the displaying of the GUI quite a bit. I addressed that problem by starting a new thread to load and process the data. It solves the problem nicely, but is there a better way to do asynchronous processing in Android applications that I missed?

Android :: ActivityList - Loading Data From Network Best Practice

Sep 29, 2010

I have multiple ListActivity(s) with a custom ArrayAdapter. I have to load an XML file from the Web, and the user moves to a new activity by selecting a list item.

What is best practice for:

Displaying a loading indication to the user.
Threading the networking stuff so that the user can cancel the loading of the data if need be / move to the previous activity.

Example/source code would be greatly appreciated - I've used http://www.helloandroid.com/tutorials/newsdroid-rss-reader as an introduction, however it doesn't display a loading indication.

Workflow When Loading Data From Server And Filling Activity Listview

Feb 7, 2013

I'm pretty new to Android development and I just hit a brick wall in the development of an app, I'm currently working on.

The problem is that I have a list of locations (states), and when one is selected, a list of cities from that state is loaded via http request and JSON and then is supposed to be inserted into a listview in another activity.

So now I have the StateList activity and the CityList activity. Currently, the statelist activity starts the citylist activity via an intent and gives it a state name. Then, the citylist activity uses that name and requests data from a server via AsyncTask. As result I get an array of City objects, which are supposed to be inserted into an adapter for a listview.

Now begins my problem: I don't want the second activity to show up before all data is loaded. I also don't want the first activity to do the request and then have to transfer the whole result to the second activity using intent extras.

So what would I have to do now to have the second activity load all the data and only then really show up? I tried only setting the content view after receiving the data, but since the base class onCreate() is tied to some manipulation of the layout, I would also have to call onCreate() at that point, which is not allowed.

Here some code snippets of what I tried already:

The onCreate() method of my second activity (which is supposed to hide):
[high]protected void onCreate(Bundle savedInstanceState) {
requestWindowFeature(Window.FEATURE_NO_TITLE);
// send request for citylist data
CitylistRequest request = new CitylistRequest(this, new State(0, getIntent().getExtras().getString("state")));
request.execute();

[Code]...

Android : Data Or List Manager

Jul 2, 2010

Anyone seen a general list or data manager app for Android? Not looking for a to-do list or task list - but a general list manager where I can define my own tables and fields, edit data, filter, sort, etc. Syncing to a PC app would be great, but I don't really expect that.If anyone has used Listpro fom Ilium Software, on Palm or Win Mobile - that's what I am looking to replace.I may end up using Excel spreadsheets with Documents to Go from Dataviz - and some general sync tool for PC to phone data sharing - but Listpro was so good, I'll miss it!
