getView() is the method that returns the actual view used as a row within the ListView at a particular position. We are creating a custom ListView of by subclassing ArrayAdapter with the DataModel as the object. Clicking the info will display a SnackBar with information specific to that row.
Clicking the row would display the SnackBar with the text elements of that row. In this tutorial we’ll build an application that consists of list of rows displaying text descriptions and an info icon.
Let’s create a xml layout that presents the items in a row in a customised way. As the user scrolls through the list, items that leave the screen are kept in memory for later use and then every new row that enters the screen reuses an older row kept in the memory. After that no new row items are created in the memory. Recycling RowsĪs a ListView is instantiated and the rows are populated such that the full height of the list is filled. There are other adapters as well, such as the CursorAdapter which binds directly to a result set from a Local SQLite Database and it uses a Cursor as it’s data source. That’s what we’ll implement in this tutorial. The simplest Adapter to populate a view from an ArrayList is the ArrayAdapter. Also to enhance the user experience, we’ll animate the ListView while scrolling. How can I determine what is the CheckBox that I selected in the ListView rows when I click a button in my application? I'm new in Android so I don't know what is the approach that I should do.In this tutorial we’ll use a CustomAdapter that populates the custom rows of the Android ListView with an ArrayList. My ListView is customized, it is contains a Icon, TextView and CheckBox, the use of the icon is to display the icon of the application, TextView is to display the name of the application, the use of the CheckBox is to determine what item in the ListView that I selected. I am creating an Android application where I have a ListView that displays all of the applications that were installed in my mobile phone.
