Android :: How To Design A Floating Keyboard
Oct 13, 2010
I am a developer and recently completed the implementation of my keyboard MessagEase. It's available on the Market (with its very- different features, making it quite unlike QWERTY).
This keyboard works fine as a replacement of the standard keyboard on an Android Phone. But for a An Android Tablet, it would work best if it's implemented as a floating, movable keyboard.
(the footprint of this keyboard is mostly dependable on the size of a human's finger; it remains the same even if the tablet's display is much larger than a phone's. Therefore it'll take a relatively smaller area on a tablet.)
If I use the current SDK hooks, it will have to take a significant portion of the screen, defeating the purpose.

how to use the IMF to design a soft keyboard. Please point me to some resources that will help me understand how to do it from the ground up. Something other than the SDK sample

I am going to develop an Android Application but before developing it i needs to have MockUp for the Android Application,so is there any way to design MockUp/GUI Design tool for the Android Application?
I know about DroidDraw tool , but i think it is not the exact way to prepare Mockup for the android application.
I have already referred this SO Question , but overthere i just found all the tools for the I-Phone only. So please feel free to share with me if you have/found any !

When the AVD screen is in an Eclipse frame there is a button on the frame to rotate orientation. How do I cause the same action when the AVD screen is floating outside Eclipse?

I wonder how to make floating buttons, like the zoom button in the build-in web browsee?
Actually there are 2 things i'd like to know:
1. How to make a view(button) floating above other views? 2. How to make the fade in/fade out effect regarding to touch screen?

It's kind of hard to explain, but an example of what I'm wanting to accomplish is like this: thought about generating the layout in html and using a web view, but I need to be able to perform an action when the user clicks on the image. Does anyone have any ideas?

I love Android, coming over from the Iphone i have Tmobile Pulse!
I love how Android had "Floating Apps" Apps which run on there own in the background, like facebook?
Is there anymore apps like this, which can do the same, a Gmail one would be awesome or news feed (RSS)
Also on my Android i have a big cluttered messy list off apps on one page, looks like this, comes with some games i don't want. How can i get rid of them ?

I've started developing an OpenGL ES app and I would like to get the best possible performace (as everybody, I guess).
As far as I know, HTC Magic (myTouch, G2) doesn't have floating point unit, so I think every calculation is done internally with fixed point math. That beign the case, altough I fed OpenGL with floating point vertex positions and normals, there would not be any permormace penalty since it would be using integer math instead of floating point emulation.

I have been searching about the floating point support on G1 phone (aka the HTC Dream phone) for a few hours.
So far, my conclusion is that the ARM-based Qualcomm MSM7201 CPU does not have VFP (floating point coprocessor) and therefore floating point calculations have to be done via software-float.
This is quite disappointing as I am interested in developing applications with heavy math.
However, I also notice that the Qualcomm CPU has QDSP4000™ and QDSP5000™ high-performance digital signal processors (DSP), according to http://www.qctconnect.com/products/msm_7201.html
Therefore, here is my question: would it be possible to leverage the DSP modules in the MSM7201 CPU to do the floating point math?
Also, I would like to develop the heavy-math modules in C/C++ and call it via JNI, and so I just want to double-check whether this is a feasible approach.

I'm currently developing a application on a HTC Dream aka T-mobile G1. afaik the processor has a FPU coprocessor, called VFP (Vector Floating Point) in ARM terms. So far I couldn't find any information about if the FPU is used for floating point calculations or if those are emulated in software. does anyone have any information about that? the opengl implementation supports both fixed point and floating point. will my applications be slower when I'm using floating point, because they get transformed into fixed point internally? or is floating point implemented in hardware?

OpenGL ES allows values to be specified in either fixed point or floating point format, but I haven't been able to find any information about how this is actually implemented on Android devices. Are there actually two different pipelines, one for fixed point and one for floating point? If so, what happens if you mix and match them, such as specifying your matrix in floating point but your vertices in fixed point? Alternatively, does it implement everything with just one format internally, and convert the other format to it as necessary? If so, then you presumably get the best performance if you always specify values in the internal format so as to avoid conversions. How then can I determine which format is used internally?

I need maths for my game physics and lots of them, so I use the. Math library. And guess what? I never casted so much to floats in my entire life. And i know how costly it is to use doubles on an embedded device because I read the performance optimization page in the google android sdk docs. So I am wondering if we couldn't get a Math package with functions taking and returning floats instead of the default doubles. e.g. Math.sinf Math.cosf.

I would like to have the following screen in my application: button at the bottom of the screen; when user presses the button, a list with a number of items will appear and user should be able to click one of those to start another activity. The number of items can be different (depending on some other conditions); the popup is to be adjusted to the button. How would you suggest implementing this?

I'm trying to decide on whether to primarily use floats or ints for all 3D-related elements in my app (which is C++ for the most part). I understand that most ARM-based devices have no hardware floating point support, so I figure that any heavy lifting with floats would be noticeably slower. However, I'm planning to prep all data for the most part (i.e. have vertex buffers where applicable and transform using matrices that don't change a lot), so I'm just stuffing data down OpenGL's throat. Can I assume that this goes more or less straight to the GPU and will as such be reasonably fast? (Btw, the minimum requirement is OpenGL ES 2.0, so that presumably excludes older 1.x-based phones.)Also - how is the penalty when I mix and match ints and floats? Assuming that all my geometry is just pre-built float buffers, but I use ints for matrices since those do require expensive operations like matrix multiplications, how much wrath will I incur here. By the way, I know that I should keep my expectations low (sounds like even asking for floats on the CPU is asking for too much), but is there anything remotely like 128-bit VMX registers?

I've got a ListActivity using the Theme.Dialog theme and windowNoTitle set to true.
Unfortunately, when I do this, the header rows (just normal rows in the list but they look like sub headers) refuse to fill_parent width (instead, they wrap_content - the header text).
I noticed this was not a problem when using the Theme theme so I started narrowing everything down to what was causing the problem.
The answer: windowIsFloating. Theme.Dialog sets this to true, and if I override this to false, then the headers happily fill the parent width.
Is there a way around this (because I would like to set windowIsFloating to true)?

I'm having a problem with floating windows. My activity has an AutoCompleteTextView text in a floating window positioned at the top of the display. If enough text is entered to make the drop down appear it will be initially clipped to the bottom edge of the window. If you click on the drop down it appears unclipped.
I've stripped my activity down to a test program and put a copy here:

In summary, the main activity just inflates a view and positions it at the top of the display: Code...

I want to show a menu similar in look and feel to the sub-menus. I want the menu to come up when we tap on the screen. Is it possible to have sub-menus displayed without creating the main options menu? I do not want to use context menus for this.

I want to show a list of items when the user clicks an overlay item on a map. The user should be able to select any of these items and edit them. The list can have many items (more than that can fit in one active screen) therefore it needs to be scrollable

I bought Beautiful Widgets, installed them and removed them from my screen. I am deciding how I want my little Zio to look. And no, I am not upset at my little problem. I love and would recommend the program. However, this AM I noticed clouds floating across my email screen after the phone sat idle for an hour or so. I took a look at all running apps (Task Killer, sorry) and nothing seems to be running that would account for the animation. I asked Mr. Google about this and he is as clueless as I am.

For those that have seen the HTC EVO 4G ROM floating around first announced on Engadget... or the technologically savvy... Can Sprint HTC Hero users/owners install this on their devices? What are the best and worst case scenarios if one were to attempt such a task? Would it actually work, what is this ROM essentially, what makes it different than the 2.1 update Sprint Hero owners just received?

Just recently gone to 2.1 (orange uk) and noticed the way the weather works now. If it's cloudy for example clouds will fill my screen and float across.
My question... what activates it? As it seems to be random when I open my home screen?

I have been looking for an app that will place a small, transparent icon on my screen that can launch an application. I would love to have an icon that looks something like the icons for SmartTask Bar and ButtonSavior. But I just want it to be a shortcut so that I can launch any other app the same way.
Here's an image of what I'm talking about.

For those of you that are familiar with better keyboard. I was wondering about an easy way to switch from the t9 keyboard to the regular qwerty keyboard. I was under the impression that swiping left would toggle between the 2 but all that does is bring me to the numbers and symbols keyboard. I've been changing back and forth to the android keyboard because its faster than going into the better keyboard settings.
