Android setsummary not updating
After creating instance call open method, which is responsible for opening database in writable mode (refer sample code above).
Now call create Student method which accepts 2 parameters name and standard and create student record.
Through this blog we will look at the following various type of Android Menus available with example for each of them: Options Menu " data-medium-file="https://androidpartaker.files.wordpress.com/2010/10/optoin_menu_2.png?w=200&h=300 200w, https://androidpartaker.files.wordpress.com/2010/10/option_sub_menu_2.png? w=100&h=150 100w, https://androidpartaker.files.wordpress.com/2010/10/option_sub_menu_2320w" sizes="(max-width: 200px) 100vw, 200px" / Instead initiating Menu in code as shown above the best practice is to define menu in XML and then inflate menu using this XML in the code.Thus by defining menu in XML, we separate design and implementation.For fetching all students from student table we will call fetch All Students of Database Util class. We will check cursor for null and then iterate through it and print name and standard for each student.Student name is fetched from cursor by calling String(1), here 1 represent the position of column holding the Student Name in the String array passed while querying the database. This post introduces you to the basics of Android SQLite Database with sample code.
As name suggest, Context Menu is the menu in context/associated with some object.
