How to handle a complex type object from webservice. Presently I am able to handle simple String messages. But if I am extracting some array of objects or String, then how to handle this.

I am trying to pass a user defined object to another activity Bundle bundle = new Bundle(); bund.putSerializable("myData", myData); intent.putExtra("bundle", bundle); where myData class implements Serializable interface. I am getting following error: java.lang.RuntimeException: Parcelable encountered IOException writing serializable object how to pass complex objects between activities?
View 7 Replies View RelatedI am trying to extend the "android.content.Intent" class by adding a private attribute of a custom class. My goal is to send complex objects from the main Activity to a background Service.
The extension itself is not a problem, the class gets compiled without any errors and the project runs. The only problem is that the BroadcastReceiver does not receive the modified Intent and the "onReceive" method gets never called.
It there any way to pass complex objects with the help of Intents?
I am working android app, where i need a Listview which contain different types of view sets. They have to update dynamically. i.e , initially i have some list of views, with one header. Next when i click button i have to add new view set with different header. So can any one tell me . how to achieve this complex listview.
View 1 Replies View RelatedIm pulling a list of product objects from a database call and I want to build a ListView of the data in my activity with a non-scrolling header and footer. Each row will consist of a product thumbnail, some data and a button arranged horizontally. I understand that using the ListView I can inflate each row using a separate layout. Most of the examples Ive seen using ListView just show a simple array of strings that fill the whole view of the activity, but most real-world examples will be more complex and I can't find any good examples that explain how all these pieces fit together. Does anyone have any pointers to sample code with a good explanation ?
View 2 Replies View RelatedThe FAQ mentions a method of passing objects around activities. (It is not clear to me): "A HashMap of WeakReferences to Objects. You can also use a HashMap of WeakReferences to Objects with Long keys. When an activity wants to pass an object to another activity, it simply puts the object in the map and sends the key (which is a unique Long based on a counter or time stamp) to the recipient activity via intent extras. The recipient activity retrieves the object using this key.".................
View 7 Replies View RelatedI have an application that have a Google map on Google Android 1.5 since we have been working on the application for a long time, we are not in stage of upgrading to the newest framework, so we are using 1.5. Now, I have map locations that are dynamically generated and drawn on the map at run-time to visualize some streams, Up to this point the application is working fine, Now my problem is that I am trying to filter the objects ( addresses) to visualize only the on-screen ones. I do NOT want to visualize the addresses that are off-screen. The way I am trying to do this is to check the screen-coordinates of each object (address) before visualizing it, then it the coordinates (x,y) more than (0,0) and less than (320, 460). I should visualize it. I am trying to use this approach, but it is not working for some reasons, I have tried many posts but could not understand why, there must be something missing somewhere that I am not aware of.
View 11 Replies View RelatedI have a TabHost that requires indicators more complex than a simple string label (the tab itself, not the contents of the tab). There is no graphics involved, just font size and layout of text. The documentation suggests I may call the setIndicator method with a View instead of a CharSequence, but do not provide any pattern to follow. This almost works -- the tabs function but are not colored properly. I can probably use OnTabChangeListener to set their background color to white or black, but clearly this is wrong also -- the orange color transitions, etc. are lost. I just want the existing label behavior on text that's laid out. What pattern should I be following here?

View 5 Replies View RelatedI am working on some sort of record lookup for a database. My code allows to search for some kind of string within an index (of that database) and returns the database-position of the found thing . With this found position my program is then able to move to adjacent records from the database moving forward and backwards from the initial position in small steps. ListView seems to not work in this case, as ListView starts per default at ListAdapter position 0 and not at an arbitrary position in the (here virtual) list. The api-docs doesn't seem to specify some sort of "start somewhere else and follow during scrolling". At least I haven't found that. So what I thought of is to use a ScrollView. Unfortunately I don't have a real understanding of how that could be realized with a huge number of records (and not just a handfull like in the examples). So, my questions are: - Is it possible to start a ListView at some defined position (without reimplementing {Abs}ListView) - Or can someone provide an example on how to implement a more complex ScrollView.
View 10 Replies View RelatedI have ListActivity to show a custom list. The adapter for this list is a complex layout only known for each row at runtime depending on data gathered in a previous activity. The question I have is simple. I know it takes 4-6 seconds to prepare the adapter for the rows that will be visible (first 10), however I would like to let the user know by means of the empty list functionality or otherwise. At present the ListActivity is launched via a button on a previous activity and when that button is clicked the new activity will not be loaded until the adapter is completed, and the user is stuck with the previous activity until this happens.

View 5 Replies View RelatedAll the examples I have found assume that Spinner is given an array of String. I have a Spinner whose Adapter contains an Object more complex than a String. I want the capacity to display some parts of this object. a) during drop down b) when the item is selected. Nothing fancy, just some straight text, but I need ot whole object. If I override Adapter#getView, the View that super#getView returns is a TextView, so I could set that to be some relevant text value, but it feels kind of undocumented. I did try inflating a layout containing 2 TextViews and populating them, but UI became a bit screwed up. I'm not really sure what's ok to change here and what's not. Likewise, the above presumably applies to the drop down view, but I am also not sure how to render the selected item.

Since Scrollview only supports one child, I've created a RelativeLayout to scroll several Views. Unfortunately, this doesn't work (no scrolling). Are there limitations to the kind of children used in Scrollview or am I doing anything wrong?
We want to add below update sql into our content provider:We found current update of content provider does not support it, which would not recognize the "column1" of "column1 + 1" as column name. So we have to add execSQL method into ContentProvider and I think it is dirt. So I wonder if anyone know how to do such thing with ContentProvider or any more elegant way to achieve it.
View 5 Replies View RelatedI am currently working on a collision detection routine for an Android based game which is capable of handling complex concave curves in 2D. I use complex in this post to describe any non-trivial, arbitrary shape (beyond circles, squares, etc). My problem is that all of the various methods I have come across are either too simplistic to be realistic or too complex for a cell phone. At the moment I am favoring a tile-based scheme but I am having problems figuring out how to do this with convex curves that span several tiles and may have several line segments per tile. I gave some thought to representing the curves mathematically, with each tile being an interval of the function, but there will likely be points where the curve doubles-back on itself (think the big loop at the top of a pinball table that brings the ball all the way around the table and back the direction it came). My questions boil down to:
1. Does anyone know of a way of hit testing a given simple shape (e.g. a circle) against a concave series of line segments (shapes beyond circles can be figured out from there) beyond just a Boolean result?
2. What is the best way to represent large, complex shapes programatically? I am currently favoring an XML file describing my levels and the objects in them with shape/position/physics/etc. data to be parsed in during load time.
3. Is there an altogether better way of doing this beyond line segments?
The one saving grace in this conundrum is that I know the vast majority of the objects are stationary with, at most, three or four (usually one) dynamic objects moving around.
I have a graphic in Adobe Illustrator (lets say a cat) that I want to use in an Android application. I would like to have the user be able to change the color of the fur using a color picker. What can I save the graphic as (SVG?) to allow me to programatically control the color from with the android app? Do I have to have a separate image for each color of the cat?
View 5 Replies View RelatedI'm new to opengl-es and I wonder how people are able to draw these much detailed OpenGL ES graphics, e.g. on Android OS. It's already hard to draw a single squre, because it's composed of triangles due to the reason that OpenGL ES obviously cannot draw anything else than triangles.
I thought about this approach:
Drawing and rendering an object in Blender.
Export it somehow as array of vertices and an array of colors
Copy this array of vertices into the Java code
Run the code
Or are there approaches to solve such problems in a better way? I do not think that people just "draw" their graphics as array of vertices in the code. I'm sure they draw them anywhere else and import it into the code.
If there is such a solution with Blender, I would be pleased to know how this is solved.
This is a bit complicated to explain (and my first post), so bear with me please: I am currently trying to figure out the best way of saving my application's state in a bundle on the onSaveInstanceState event (working on a game). My application's state is based on a "world" class which contains various objects. Among these objects there is a creature object which contains bitmaps (Bitmap object)(allowing me to draw the various sprites of the creature when it's walking with more flexibility and accessibility).
Bit of creature constructor Java:
CODE:.................
After looking around for a few hours I found that serializing the world object (and all its sub-objects) was an acceptable way of saving it in the bundle. Unfortunately it appears that we can't serialize bitmaps and considering they're a part of my "creature" I can't seem to see a workaround.
Here come my questions: 1- Am I doing something fundamentally wrong? (not supposed to save bitmaps in objects? supposed to handle bitmaps in a separate class which I don't pass on the bundle and reload my bitmaps when restoring the application? ...) 2- Is there another way of passing my "world" object into my bundle (would using Parcelable work?)

We have a SOAP webservice that is used for an iPhone application, but it is possible that we need an Android specific version or a proxy of the service, so we have the option to go with either SOAP or JSON. I have a few concerns about both methods:
SOAP solution:
Is it possible to generate java source code from a WSDL file, if so, will it include some kind of proxy
class to invoke the webservice and will it work in the Android environment at all? Google has not provided any SOAP library in Android, so i need to use 3rd party, What about the performance/overhead with parsing and transmitting SOAP xml over the wire versus the JSON solution?
JSON solution:
There is a few classes in the Android sdk that will let me parse JSON, but does it support generic
parsing, like if I want the result to be parsed as a complex type? Or would I need to implement that
myself? I have read about 2 libraries before here on Stackoverflow, GSON an Jackson. What is the difference performance and usability (from a developers perspective) wise? Do you have any experince with either of those libraries?
Playing around with the UI and SQLLite for a while and it looks pretty good to me . We have a requirement that for the App that all the questions would be coming from the server through REST / Web service which would be displayed on the App..
say for e.g if there are 4 questions
1) Enter your Name -- Text Box
2) Did you sleep well last night -- YES / NO
3) How many hours did you sleep - Text Box
4) How did you hear about us -- Drop down
So the requirement is that the Questions would be displayed on the App after doing a SYNC with the server during the SYNC with the server the Questions would be downloaded from the SERVER through REST / Web service..if the phone is not connected then pull the questions from the Database...
These questions are simple questions and they change quite often and we have a similar app which is there for iphone which does this ....
can anybody give example of rest webservice in android
