I am conducting a study about android dynamic UI. Dynamic UI means the GUI components and their listeners are created/registered dynamically. For example, one may register/remove an event listener for a GUI component in the event handler of another GUI component. I would like to know whether such cases are common in real development. And it would be better if you can tell me how many android apps you have developed.

For those who have this case please vote! After you have put on your case for awhile and taken off the top part of the case, has it loosened the left side of the screen? I feel like this case might be responsible for slightly spreading out the space between the screen and keyboard on the left hand side! This has caused a clicking issue whenever pressing anywhere on the left hand side of the case!

(basically by not working I mean, almost every video you try to open you get a message saying: "Sorry, this video cannot be played")Also, does anyone have any logical ideas as to why not EVERY Eris user is affected by this bug?

View 2 Replies View RelatedI am new to this android stuff and SQLlite etc.I am going to log some numbers at a certain interval, and will put them into a dynamic histogram, by dynamic i mean that there will be a maximum number of samples in the histogram, the histogram and age stuff should be persisted either in db or plain file.For simplicity, I would like the samples to be stored in a blob type datafield, but i cannot se if this is possible. Alternative i could have another table with the samples Or I could simply have files with filename = name and content = samples.my concern might be unclear by now, but put simply, what is most effecient regarding power usage?
View 3 Replies View RelatedI define once in my /xml/widget.xml the minwidth. but what can i do when I need to inflate different sizes from my widget layouts for 1 one my 3 widgets thats fine, but the last 2 widgets would just need one icon size, so they always need the width of 2 icons. also when I make minwidth smaller.. it fits with the other 2 widgets but the large widget come cutted.How to solve that. I cant believe to create a total new receiver and a new /xml/widget2.xml just for another size?!
View 10 Replies View RelatedI want to create a TextView that will stretch the width of the screen and use a textsize that will keep the text on one line and fill the width. So bigger words would be smaller fontsize and smaller words would be bigger font size. I tried digging around in the docs under TextView but could not find what I needed.
View 2 Replies View RelatedI need a gallery to be able to hold up to thirty custom views. These views need to added or removed whenever, they also need to be able to be display in a display bow beneath the gallery. How do I do this?I looked at the doc file for arrayadapter but it requires me to use a reference Id for each view I add, but each view is all java coded. Should I just use setId upon creation of the view and just throw that id into the array adapter, or is there a way to create one without using resource id's?

View 2 Replies View RelatedI've been reading the (shoddy) documentation for the Google Maps API (MapActivity et al), and I think I have roughly worked out how it works. It seems that if you want to add a marker overlay you can use ItemizedOverlay easily, but you have to add all your markers at once. There doesn't seem to be any way to remove them.
What I want to do is query markers from an online database as the user pans around (in the same way the actual map tiles are fetched). Is there a simple way to do this?
As far as I can tell I need to subclass Overlay and implement the draw method, but where is the best place to put the code that fetches new markers when the map is panned? There doesn't seem to be an onMapChanged() method anywhere. My best guess is MapController.onKey() but that seems wrong.

I'm trying to find a way to open resources which name is determined at runtime only. Let me explain in more details. I want to have a XML that references a bunch of other XML files in the application apk. for the purpose of explaining lets say the main XML is main.xml and the other XML are file1.xml file2.xml...fileX.xml...
what i want is to read main.xml, extract the name of the xml I want (fileX.xml) for example. and then read fileX.XML. the problem I face is that what I extract form main.xml is a string and I can't find a way to change that to R.raw.nameOfTheFile

The structure is the following:

My customRelativeLayout at the bottom of the XML has a XML layout too:

My CustomRelativeLayout:
CODE:.....................
What I want to do: I want to be able to change the position of my CustomRelativeLayout. It should be follow my touch. Its smaller than the SurfaceView and should "slide" above following my touch...
There are two problems:
The onTouchListener bind to mLinearLayout (in CustomRelativeLayout) is only triggered once and only for ACTION_DOWN. I see the log output only once The note never changes the position, it is never redrawn with the changed matrix... I see the output stated in onDraw never after the touch happened.
First might be because the SurfaceView also handles touch events. But I thought if the CustomRelativeLayout handles it first, it should work.

I also found a bug/feature/issue, which is absolutely new for me: When I remove the background in my note root element (which is currently transparent) the note is only visible within the 200dp width/height I have set in the inner LinearLayout. So its not fill_parent, its wrap_content even as I set it to fill_parent. So layout_width and layout_height only use the given fill_parent when a background is set...
Is it possible to create just one class and use a variable for contentview? I am thinking of creating a main layout with loads of buttons with IDs. Once a button is pressed it'll then pass the ID to the class and use that ID to open a specific Layout. One class, multiple layouts. code...
is it possible to make 'main' a variable?

View 1 Replies View RelatedI have created a table with 2 rows in it. Each row has 5 TextViews with a default text of 0. There is also a button outside of the table. I am trying to figure out how to update each of the TextViews in each row on each successive press of the button. So on the first press of the button the first TextView in the first row should update to 1. On the second press of the button the second TextView in the first row should update to 2...etc. I can't figure out how to do this programmatically without having to code it all - is it possible? Basically I guess I need to build up the ID of the TextView dynamically. So if the TextViews have ids as item1, item2, item3 etc. Then I need to build up the findViewById(R.id.item + i); Obviously this is not possible but is there a way to do this?

View 2 Replies View RelatedI want to add a non-native shared library to Android so every application on the device would be able to use it. I mean using packaged classes just like a core library as if they were present in the application itself. I studied Android source code to figure out a way to add a new path to the application ClassLoader and found out that it is created during startup and there's no way to change the paths later. I can use my own ClassLoader, but all I will get after loading a class will be a reference to a Class object. This way I will be bound to work through reflection mechanism, which is slower than the native execution system Is there any way to organise a shared library on Android?

View 1 Replies View RelatedIs there a way to dynamically load/use a custom recovery on an Andoid phone (generally, any phone) without actually having to overwrite the phone's stock recovery? For example, by booting to stock recovery, flashing a zip file that will start up CWM/TWRP so you can use it temporarily, but stock recovery is still there and when you reboot the phone it will still be there? Sort of like using a Linux live cd.
I'm asking about this because I have a phone that I want to get into that is protected by a pattern lock. I haven't examined it yet, but I am strongly expecting:
- No root
- No custom recovery
- No ADB debugging enabled
I know I can bypass the pattern lock from CWM/TWRP (rm /data/system/gesture.key)...but I would prefer to not have to do an overwrite of the recovery partition if it can be avoided.
