Such as when I use the ArrayAdapter class, I want to know what is be done in the class. Sometimes I want to go the source code to find answer.
So, my question is where can get the source code ?
http://source.android.com/source/index.html
http://grepcode.com/snapshot/repository.grepcode.com/java/ext/com.google.android/android/2.3_r1/
https://android.googlesource.com/platform/frameworks/base/+/froyo-release/core/java/android/widget/ArrayAdapter.java
is the link for ArrayAdapter used in the latest Froyo release from Googles open source repository. You can use the navigation links on that page to get to the other parts of the available source code and other releases of Android.

is there someone who can help me to find a android code to create a kitchen >timer (I am a beginner)
As said in the comments, not sure why you didn't just search Google. However I'd advise using the inbuilt CountDownTimer class. Here is an example of how to set it all up:

In my android application I am using Spinner.It is working fine.
But I want to show my spinner in different style as per mentioned link
Kindly provide me solution for the same.
Hi if you can use a 3rd party library I will recommend you to use this one. I used it and it's working fine.

Inside the repo are the steps to use it.
Is it possible to get and watch at Android's program component's native methods code. If anyone knows how to, please let me know.
You can find source code for Android native methods using Google Code Search one of the following services:
AndroidXRef
GitHub (using repo:android/* search term)
The search for "SystemClock || android*SystemClock" in AndroidXref will point you to the android_os_SystemClock.cpp file which in turn forwards many of its methods to SystemClock.cpp
Other Android .cpp or .h files with native methods implementations could be found in a similar way.
If you are looking for android SDK code then you can find it here:
https://android.googlesource.com
https://android.googlesource.com
git clone https://android.googlesource.com/platform/frameworks/base
For Google application look at platform/packages/apps/[APP name]
Beside the Android Open Source Project you can find the code just by using google, e.g. search for:
android SystemClock source code
I got links to grepcode (SystemClock). I find it more compfortable to browse the code here (be careful which version of code you are browsing).
I am trying to look inside a couple of Android core classes to see about overriding some methods. I have looked into getting the Android source code, but the process described on the Android dev site is all about installing and setting up some kind of development environment. This is not necessary to me. I just want to open a class or two in a text editor and look at its contents. Does anyone know if this is possible without going through the multitude of steps described on the Android dev forums?
The easiest way is to use Google Code Search. You just have to try a search like Activity.java android and you can see the source code of that class. It even has an outline inspector:
You can download the entire source with git our just look it up as a reference on the git site. Here is a link to the sdk code:
https://android.googlesource.com/platform/frameworks/base
Another option is to use http://grepcode.com/ and perform a search such as "android ViewGroup". I've really enjoyed the style of using grepcode.
Are the Android APIs open source? If so, I want to see how they implemented the smoothscroll method for the ListView object (this is implemented in API level 8, but I want to build against an earlier API level). How would I go about finding this?
Yes, it's open source, and http://source.android.com/ has all the information on how to download and browse the source.
This is what you want: ListView source code.
