I have a simple Android app that does some math on 2 numbers that the user inputs and returns the result.
Currently I have a 'calculate' button that needs to be pressed to do the math and return the value.
How can I get rid of this button and just get the app to run the math after the uses has changed either one of the 2 numbers?

CursorAdapter is great, i'm a big fan. I notice that both newView() and bindView() are passed Cursors, indicating that extracting stuff from the Cursor and sticking it in the view should happen inside those overrides.
however in the source for CursorAdapter.getView() i see that bindView() gets called whether the view is recycled or not. in the new view case, this causes a redundant Cursor to View copy.
IMHO, CursorAdapter should call newView() if the view couldn't be recycled, or bindView() if it could.
I have numerous activites in my Android app., and most should contain the same, relatively complex set of UI widgets on the screen's top area (lets say that its a kind of toolbar that you can find on most screens).
Right now, every screen's layout contains the markup for this toolbar, along with its logic inside every Activity's source, so it's damn redundant. Could you recommend a more efficient / less redunant way to do this?

This would fix my only complaint about the phone! It's quite annoying when I'm in a call and doing something else on the phone, and I lose the soft end call button and can't hang up.
View 1 Replies View RelatedI'd like to know how to make a button out of a PNG and display it on my canvas (using drawBitmap?). When I click on this button, it will take me to a new activity. All this will be in the onClickListener. So, how do I take a PNG, make a button with it, and draw it on my canvas? I looked at ImageButton, but I'm unsure how it works or how to draw it on the canvas.

View 1 Replies View RelatedIs there an app or widget that can be used to make a larger button? I'd prefer a 2x2 size that I can use to direct dial while driving rather than having to fiddle with the small 1x1 size, but anything bigger than the standard would be fine.
I've only found apps that make smaller buttons and one that makes me select subsequent options before I can actually call. I just want a large single press widget.

I have a GridView with a BaseAdapter that cycles through the elements making views for each element or cell in the grid.
What I would like to do is create a clickable image/button, and when the user clicks or touches it, for it to remain clicked and highlighted so that they make click on several if they so choose.
I have tried, ImageButtons, Buttons, ImageViews, LayerDrawables(with a swapable background color drawable), ToggleButtons, CheckBoxes, derived my own CompoundButton, but nothing seems to work.
I was a teeny bit successful with a ImageButton where I could create it selected, but if the user clicked on it, I couldn't get that visual state back.
I want to change the text inside a button to be bold when the button is highlighted or pressed. I currently use a xml file to define the button and use the XML to change how it looks when pressed but I would like to do this without using an image.
View 2 Replies View RelatedI'm using a datepicker in Android to let the user to choose the date. I want it to do one thing if the user picks a date and sets it (I have that working fine) and then to clear a certain text field if the user pushes the cancel button on the datepicker (open up the datepicker but then cancel out of it).
The way I've been trying is by making a code...
to attach the listener.
My problem is that the listener works if the user pushes the back button, but not if they push the cancel button. I tried using a dismiss listener, and that works, except for the fact that it goes off even whether I set or cancel the datepicker!
What do I need to do so something goes off if and only if I push the cancel button on my datepicker?
I am creating custom shapes for certain buttons but I want them to maintain the systems current color scheme.

View 4 Replies View RelatedI'm a newbie to this forum, and hope someone can help. Have had the Captivate for almost a month now and am plagued by an annoying problem. I have set up email accounts connecting to a google-hosted email account via IMAP. I am finding that when replying to a received email, my reply goes out with redundant repetitions of the email address on the "to" line. Example: Email from soandso@gmail.com arrives. I click "reply" on the phone and the reply goes out to soandso@gmail.com; soandso@gmail.com; soandso@gmail.com; soandso@gmail.com etc etc *10 times*, instead of just once. It also copies me about 10 times! Is anybody else seeing this? I use this for work emails, so it looks very unprofessional like I am trying to spam my clients! I have another couple of days before my 30-day return period is up, so hopefully someone else know how to fix this. Is there some setting I am overlooking?
