Android sqlite pagination in TextView

I am using Android studio with SQLite database is built-in, I am fetching some text from a table of 2 columns into TextView.
I want to use next and previous button
When the Activity starts, it loads the first record of a table in TextView but when I click on next button it should fetch next row of the table in TextView and when I click previous it should fetch the previous row of the table.
I am new to Android I searched about that but unfortunately found nothing.

try this. it could help you.
when a user enters in Activity fetch all data from Database and store that data in ArrayList at particular index . On click of Next Button get data from ArrayList according to it's index.

Android Sqlite Database Formation

In my application I take entry from user as :-
Name:- -------------------------
Favorite Fruit:- a)
b)
c)
--------- Add More ----------
Then I want to save it into a Sqlite database. Now I provide user to type in edittext search like this:-
Search Fruit:- Apple,Banana
And then I want to query my database and Print the name of those who like atleast Apple and Banana.
Now my issue is how do I make my database columns to achieve results faster.
Should I make two columns Name and FruitsLiked or something else. Because if I make only two colums then how do I search into database.
Thanks

Create one table n two columns. First column is for name , second one comma separated list of fruits.
Then as db query use like keyword based query

you may use button or any event to fetch the value from the database. you can run query on the database and store the value in the cursor. as far as code is concerned for fetching the value from the database you may http://www.vogella.com/tutorials/AndroidSQLite/article.html or http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html or http://www.androidhive.info/2011/11/android-sqlite-database-tutorial/

Managing a sqlite database using activity list

Ok, I have a database with id column as timestamp
I made an activity list from the db.
I want to manage the db (delete rows) using the list, but the thing is I don't want to
View the whole timestamp, in every row I'll put only the time with some info and
I want to group the list ,as in contacts grouped by alphabet, by the date.
First, how can I make group in an activity list? (Making groups to the output list not the db)
Second, what is the best way to implement this? When user chooses an item and confims delete
I should delete it from the db but I have only patial timestamp...
(My only link to the db is the timestamp - I don't actually know where to store it in the list and I don't want to put it as a string in the text view, do a substring to get it back - is there another way to do this?)
I tried to search tthe web for some examples but I only found a simple ones.
Thnx :-)

I think what you're trying to do is create a database of tasks identified by a timestamp. You probably don't want to use a timestamp as a unique ID for the row. Instead, use an integer and qualify it as "PRIMARY KEY" when you create the database.
group the list? I'm not sure why you want to do this in the structure of the database. It's more common to group the list in the output, and leave the db itself in as flat a structure as possible.
Retrieve the primary key when you display a list of tasks. When the user clicks a task, use the primary key to choose the task to delete. You don't have to display the primary key; it serves as a behind-the-scenes "link" between the displayed info and the db row.

I should use cursor adapter for managing db.
And this one for grouping a list:

Android- save date and text to SQLite in phone's internal memory?

I currently have a layout with an EditText field, Datepicker, and a button. I'm trying to find a code that would make it so when the button is pressed, the values of the datepicker and edittext are stored in a SQL file so that it may be retrieved later.
I'm fairly new to using the SQLite functionality on android, and couldn't find a solution to this myself. Thanks!

Firstly read documentation regarding SQLite database from
http://developer.android.com/reference/android/database/sqlite/SQLiteDatabase.html
http://www.vogella.de/articles/AndroidSQLite/article.html#overview_sqlite
To store value on click of button follow the steps.
Create DbHelper class extends SQLiteOpenHelper in which you can create table for required values to store in database for e.g. db.execSQL("create table "+EXAMPLE_TABLE+" ("+EDIT+" text, "+DATE+" text )");
Create a class ExampleProvider extends ContentProvider which manages queries like insert, query(select) , delete and update.
After that on click on button retrieve the values from edit text and datepicker , then store it into one object and then using resolver fire the insert query.
Check out from commandline whether values inserted into db or not.
Similarly you can retrieve values from your databases using query() method which retrieve data in form of cursor .
