You can reset to zero when you are starting over.
Let us look at the final product before writing some code: Unlike my first post, this will not show you how to setup the development environment for android applications. If you need to do so, please read through the setup guide here and then come back for another exciting learning experience.
Counter App Definition This app is relatively simple but not as simple as the todolist we created earlier.
We will be using a few more things that might be new to you. Here are some of the things we will use in our development. Instead of hard-coding strings, we will use values and resources that we will set inside the strings.
The main activity that we will define will implement an interface. We are not going to do that here because we want to make things easier to understand and stick to good coding styles. There will be three buttons. If one is clicked, we do something after knowing which one was clicked.
The first button will add 1 to the counter, the second will subtract 1 and the third one will reset everything to 0. There will be a few fancy things we will add: Likewise, when you click add or subtract, the score background will change as well.
The layout will include three components: TextView, EditText and Button. I know you are probably thinking, show me the code. It is okay, but I think it is also good to understand the structure of the app before doing anything else. Files that we will use MainActivity.
There are several folders that get created when you create a project using the Android tools on Eclipse. In those folders are files that you can use to add resources.
You are free to look inside those files but since we are not dealing with them directly in this post, I am not going to talk much about them. Fill in the details of your project and application.
When you are done, you should have your project ready to go. Yours might have a different name. Doing that will save you a lot of time. Drag and drop EditText — resize it as it pleases. Drag and drop your first button. Drag and drop your second button.
Drag and finally drop your third button.
Remember, what you see after dragging and dropping the components to your view is how your final app will look like. If you look inside your main. The Resource window looks like this: I am saying this because some people might have the idea of a string having double quotes around them.
As you can see, the last android: The same applies to the three remaining buttons. If you know a better highlighter for WordPress, please tell me. We will need those ids to reference the components inside the java code that we will write next.Pro Android Python with SL4A: Writing Android Native Apps Using Python, Lua, and Beanshell [Paul Ferrill] on benjaminpohle.com *FREE* shipping on qualifying offers.

Dear Lifehacker, I have some background in coding, but I've never touched Android development before. I'd like to get started, but I'm not entirely sure what I need. I don't need to "learn to code" per se, but I could use some guidance on where to start with Android.
I am working on android quiz. I have setQuestion() method in QuestionActivity class. I have benjaminpohle.com in which i create TextView to show scores.
I want to write code in setQuestion so that its set TextView of that button with benjaminpohle.comlly my scores are retrieving from getScore() method in GamePlay class and scores updated with right or wrong answer. like in setQuestion() method my next question answer .
Android apps have a wide variety of features, functionalities, and purposes. These various Android apps require similarly varied support from Android system APIs.
