Creating A layout.xml For Calculator Layout Design | CalculatorPlus

May 10, 2012 1 comment

We are done creating the layout.xml file for the calculator design, it was a tough one because I was forced to read the design documentation and the design techniques in order the come up with  what design  we want. The important thing that we did was the android:layout_width="fill_parent" because its the thing that makes the row and column to be even and no overlapping between the buttons.

Kudos to the internet of course especially StackOverFlow.

After all the necessary feature of the program is done I’m gonna upload all the codes for the community. Oh and btw that Button H there is the unique feature of it.  We will be implementing it in the future.

In a few weeks we will be coding the it is where all the Java codes will be added and the functions that will make the program a workable piece of awesomeness.


Menu ListAcitivity instead of Acitivity in Android | CalculatorPlus

May 8, 2012 Leave a comment

Its been a while since I updated the Android Project, the reason is that I need to read and study some of Java and its functions its really confusing sometimes. Anyways there is a lot of ways to display the Menu in Android but this method that I’m using is the dynamic way of displaying its contents in the menu, instead of manually setting it up in the Manifest structure, I will just directly call the Activity without the hassle of configuring the Manifest file. So its like shortening the codes that will be using.

Honestly I also learned this method in just watching the tutorial and took me 2 days to fully understand the code then tweak some of it according to my needs. Anyhow here is the picture of the phone screen running the Menu ListActivity, since there is no file about this screen in the layout.xml then the only way to make it appear is the run the whole package.

The menu is pretty much fully set up now we only have to worry about the Calculator Class and SciCalculator Class, I started creating a design prototype of it but then I got lazy 😛

If you’re just starting to develop an android or anything really. YOUTUBE best teacher ever, and oh did I mentioned GOOGLE?

Bits And Pieces of The Application

April 24, 2012 4 comments

Yesterday we presented the overview of the application plan. Now we will try to explain each of them and the intents of each of the Activity(Pages). We will start on the SplashScreen Activity:

public class SplashScreen extends Activity() 

This here when the user click the icon the first thing that will happen to the application, it will show the logo, title and the version of the application. Usually SplashScreen isn’t really that necessary because we can operate even though it is disable, We will  implemented it for the purpose of beautifying the application. This is the first thing that I will do since it only takes few codes the work.

public class MenuMain extends Activity()

After the SplashScreen this is the next thing that will happen to the application it will direct the the MainMenu Activity . There is a lot of ways to implement menus but since we are aiming for simplicity we will just use buttons. Buttons are great for everything when you get used to it, a whole new world of ideas you will discover. Maybe for the future projects we will use the more advance method of menus like widgets.

 public class CalculatorMain extends Activity()
public class SciCalculatorMain extends Activity() 

 This is where all the magic happens this is where the core of the application is, we will codes together on this area more often debug stuff and shit. Since it needs to have a database to store the last 5 equations, we will have a research on SQLite platform on Android since we don’t have any idea on how to implement it or try to see if there is any other solution rather implementing the SQLite.

public class AboutApp extends Activity()

We will put in here the ones who help contribute to the project, the one who is supporting it and making this impossible stunt possible. We will get famous in no time guys. haha

Thats it for now,  tomorrow I will probably create the visual images of the application and take a screenshot and show it to you guys, I will also show you how to make the UI its as easy as 123 trust me.

BTW naa nay ni sign up isa ka bouk for the Designs sa application lamats kaayo bai, due to his request dili sya paila hehehe


Rough Draft Of The Calculator App

April 23, 2012 Leave a comment

I just finished with the rough draft, basically this is the flow or somewhat pages of the entire application, It would be best if we have an icon, logo, background but that is really not important at the moment, we need to first make each pages and make features in each and everyone of them. At the end of the week I will create a written Project Proposal for everyone to read and code some of the parts in order for the project to start running.

Some of you might be wondering why Calculator? Calculator because it is a very simple program yet we can cover almost all the basic android programming terms on how to code. So its like we are familiarizing the Android Development by building a simple calculator after this we can continue making more complex applications and move forward. One step at a time guys. WE CAN DO THIS.

Anyone can join or just watch on how to develop applications or ask questions.. really guys we really need your support!

For anyone who wants to have the developer’s kit on Android I have the complete files if ever you want to have one. Its easier for you just get it from the usb than to download because it takes hours to download all the files.

For those who want to start reading about android development please go to their site Android. All the things are found their including the downloads and tutorials, I’m recommending you guys if you start on HELLO WORLD app so that you can grasp parts of how to code inside Android.

*And for those you want to learn designing naa sad didto on how to design the logo icons background.
Pag practice2x lang sad ug Java kay mao rajud atong gamiton sayun ra ang Java basa2x lang gud.
Mag himu pud ko ug site nga dedicated ani nga project so everyone can sign up and post their ideas works and etc in the site so every can see.
