=====Changing Views in Activity=====
in Android switching between views is a way to keep information, which have been given by user [[http://www.codecamp.fi/doku.php/android/filehadling|without saving them to file]] or [[http://developer.android.com/reference/android/os/Parcelable.html|making them parceable]]. But unfortunately it also takes some work to get it working. Other solution to get same result [[http://www.codecamp.fi/doku.php/android/multibleactivities|is using multiple activities]]. 
tab pane is a way to make using multiple tabs easier.

Here is example of changing views in one activity. Also uses random, multiple threads, changing text colour,size of buttons and similar.
