Two TextViews in a layout define the template for each two line list entry. Normally such arrays are read from a database or a web service. The code in this tutorial will define a two dimensional string array to hold the American States names and capitals data. Adding another line of data for each entry in the list requires the SimpleAdapter. For a list with single line entries an ArrayAdapter does the job, as seen in the Add a Simple List to an App example. In the case of a ListView (or ListActivity) the work is done by an Adapter.
When entering code in Studio add import statements when prompted by pressing Alt-Enter.) A SimpleAdapter Loads a ListView with Two Line EntriesĪ common pattern in Android is to define a View in XML, set up the data that will be displayed in the View, then provide the code to load that data into the View. The example code can be changed to meet your own requirements. (This Android Two Line List tutorial assumes that Android Studio is installed, a basic App can be created and run, and the code in this article can be correctly copied into Android Studio. The two line list example in this tutorial also applies to a ListActivity which is simply an Activity with a built in ListView. This article shows how each list item in a ListView can display two lines of data, in this case each list item will be an American state and its capital. In the tutorial Add a Simple List to an App example code was given to show how to load a ListView from a string array.
