Android :: Getting A Button Along With Gridview?

Aug 22, 2010

I have a gridview that is inflated by multiple buttons. I used just a gridview and it worked fine. The grid was in correct order and was centered. Although, I wanted to add a button below the grid of buttons that was different and centered. To do this I decided to section off the gridview and then add the button (therefore it wouldn't be affected by the gridview).

I tried the following code to seperate the views:


The problem is that this code smushes the gridview to the left and oddly it flips it (Position 0 is ont he bottom right and the last button is on the top left pushed off screen). The following image shows what is the result:

Any idea why its pushed to the left and flipped? Or maybe how I could have just the Gridview with the button on the bottom?

HTC EVO 4G :: Calculator Not Working Properly

Sep 1, 2010

So, the moral of the story is "Don't use the native calculator to do your taxes". Open the standard calculator, and enter 49990-49602.62 (a simple subtraction problem) Then push the = sign. Handy-Calc (excellent App) does not do this.

Motorola Droid :: Calculator Not Working Properly

Mar 3, 2010

The calculator app that comes with the Android OS apparently has an error. I've confirmed this error with two other Moto Droids and one HTC Android phone. In the calculator app enter:

3322.72 - 3321.92 then = and the answer is .799999

The correct answer is .80. This may seem like a minor point (.000001 error) but the answer is still wrong! Basic arithmetic operations should be a no brainer.A Verizon service rep confirmed this error on the Droid and Eris phones he had in their call center.

Android :: Financial Calculator

Apr 18, 2010

I did a few searches, and came up empty handed.I'm trying to find a decent financial calculator, similar to a BAII+ by TI.I want something that has at least a row of TVM buttons (n,i/y,npv,pv,fv,etc.) Also, it would be great to find something with a cash flow register.Is there anything like this out there? I know the official BAII+ is available to purchase for the iPhone, just wondering if something comparable is out there for my Eris (rooted, 2.1)

Android :: Construction Calculator App?

Dec 16, 2009

I have a BB Storm, but no construction calculator app is not available for the BB OS. Is there one for Android? There is a product called Inchcalc for the iPhone inchCALC iphone application and of course the real thing by Construction Master Pro with Construction Master LT - Calculated Industries. I contacted inchcalc and a few other small developers about making a BB version as there were several people on the forums asking for it. Inchcalc's response was that "we feel the Apple OS is the future and are focused on that platform..." At any rate, I'm CERTAIN that I will be moving to an Android phone. (and smashing my Storm with hammer to create an art piece--I'll call it frustration in 3D) Having a construction calculator app on the phone would mean one less device to carry around.

Android :: Regular And Scientific Calculator?

Mar 31, 2010

I looked thru lots of calculator apps but they seemed to be either tip calculators or scientific ones. I'd like on that's just like the calculator i use at my desk. I know how to figure out what the tip amount would be so don't really want one that does only that. and the one that seems to be in my Droid doesn't have a % key, unless i've missed it. I just don't see the need to have 2 different kinds of calculators taking up space on my phone.

Android :: Overlay OnTap Not Working After Back Button?

Jul 29, 2010

I have several Overlays drawn on a MapView with ItemizedOverlay, and an onTap that works when I first start my app. However, if I press the Back button on the Android then start my app again the onTap does not work at all. Other touch sensative operations work fine, like long press on the map and several face buttons. It is also fine if I press the Home button on the phone then go back into my app, so its only on the Back button. It will also work if I first open another app like the Maps app, then go back into my app, acting like a reset.

Overriding the onBackPressed method to move the task to the background also does not work, does anyone have any ideas what would cause this? It happens in both the emulator and on a real device.

I don't know if it will help but here is the relevent code:
