I want to create a table in SQLite in which one of the field is for date, in which date and time of current instance should save. Which data type should I use?
I'm planning to use 'timestamp'. How to insert current timestamp value to the field? Also how to write content values for this date field?

The SQLite function DATE('now') returns the current date as a text value. It uses the 'YYYY-MM-DD' format, where YYYY is a 4-digit year, MM is a 2-digit month, and DD is a 2-digit day of the month. This function takes one argument: the text 'now' indicates the current date and time.
SQlite does not have a specific datetime type. You can use TEXT , REAL or INTEGER types, whichever suits your needs.
This example demonstrate about How to store values with current time in Android sqlite. Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project. Step 2 − Add the following code to res/layout/activity_main. xml.
SQLite supports the standard SQL variables CURRENT_DATE, CURRENT_TIME, and CURRENT_TIMESTAMP:
INSERT INTO Date (LastModifiedTime) VALUES(CURRENT_TIMESTAMP) The default data type for dates/times in SQLite is TEXT.
ContentValues do not allow to use generic SQL expressions, only fixed values, so you have to read the current time in Java:
cv.put("LastModifiedTime", new SimpleDateFormat("yyyy-MM-dd HH:mm:ss").format(new Date())); 
INSERT INTO Date (LastModifiedTime) VALUES(DateTime('now')) Use this site for further reference.

To get the current local(system) time, add the 'localtime' option:
select datetime('now', 'localtime');
