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.

I am working on an android project. Its a tutorials app in which I am providing 100 chapters. But I am not getting exactly how to store these chapters in my app's local database and how to fetch it on button click. I want to provide the facility on button click the next activity must be opened and the contents of the chapters must be loaded on that activity.
For Example. If I click on Button "Chapter 1" then 1st chapter must be loaded from SQlite database.
I have followed lots of tutorials but I am not satisfied. Please Somebody Help Me.
You have 2 choices:
TEXT type - SQLite supports very long text.
Source: http://www.sqlite.org/faq.html#q9
SQLite will be happy to store a 500-million character string there
BLOB type: If you don't want to use TEXT, you can use BLOB instead ( You need to convert the large text to a byte array when inserting/updating, and convert the byte array to back to the large text back later)
For database design. You can do like this:
- Book table ( _id, name, ...)
- Chapter table (_id, content (TEXT,BLOB), book_id, chapter_number, ...);
So, I have an Android app that is essentially a ListView(MainActivity, fill_parent). And details activity(DetailsActivity) with a bunch of TextViews for Name, Phone and Email.
You tap on a list item in MainActivity to initiate the DetailsActivity to see more info about the selected item from the list.
There's a MySQL database with one table that contains ID, Name, Phone, Email and Image columns for each person. Image column is just a VARCHAR that contains filename of the appropriate image to every record.
Between database and android app is PHP webservice. It's used to get all persons(get_all.php, for the ListView to be populated) and also get detailed information(get_details.php) about a particular person based on ID passed to it(populates DetailsActivity).
I assume ImageView widget(DetailsActivity layout) will have to be used to display the images, so that's not a problem.
Problem I'm stuck at is where should I store the actual images in order to pull them into the app when DetailsActivity is started for a person?
You should use cache your pictures to SDCard.
Here is a great lib that will help you to achieve it:

So, you will have all your thumbnails on your SDCard.
When you will open the DetailActivity, that's the time when you will copy the full size picture on SDCard.
