Day 38

We worked on RecyclerView today.The RecyclerView widget is a more advanced and flexible version of ListView.
In the RecyclerView model, several different components work together to display your data. The overall container for your user interface is a RecyclerView object that you add to your layout. The RecyclerView fills itself with views provided by a layout manager that you provide. You can use one of our standard layout managers (such as LinearLayoutManager or GridLayoutManager), or implement your own.
The views in the list are represented by view holder objects. These objects are instances of a class you define by extending RecyclerView.ViewHolder. Each view holder is in charge of displaying a single item with a view. For example, if your list shows music collection, each view holder might represent a single album. The RecyclerView creates only as many view holders as are needed to display the on-screen portion of the dynamic content, plus a few extra. As the user scrolls through the list, the RecyclerView takes the off-screen views and rebinds them to the data which is scrolling onto the screen.

Today we started working on UI of our application and we developed sin up and login forms and customized it's design. The user interface for an Android app is built using a hierarchy of  layouts  ( ViewGroup  objects) and  widgets ( View  objects). Layouts are containers that control how their child views are positioned on the screen. Widgets are UI components such as buttons and text boxes.

In  android , Event  Listener  is an interface in the View class that contains a single call-back method.

Day 62

Worked on time stamp of a ride and history of single page system. A thin wrapper around  java.util.Date  that allows the JDBC API to identify this as an SQL  TIMESTAMP  value. It adds the ability to hold the SQL  TIMESTAMP  fractional seconds value, by allowing the specification of fractional seconds to a precision of nanoseconds. A Timestamp also provides formatting and parsing operations to support the JDBC escape syntax for timestamp values. The precision of a Timestamp object is calculated to be either: 19  , which is the number of characters in yyyy-mm-dd hh:mm:ss 20 + s  , which is the number of characters in the yyyy-mm-dd hh:mm:ss.[fff...] and  s  represents the scale of the given Timestamp, its fractional seconds precision.
