What is the function of ArrayAdapter in Android?

ArrayAdapter is an adapter class in Android used to bind data sources with view controls such as ListView or Spinner. Its purpose is to bind data from the data source to the view control one by one and display the views on the screen.

Specifically, the ArrayAdapter customizes the layout and display of each list item by overriding the getView() method, binding each element from the data source to a view control one by one, and displaying them on the interface.

Using an ArrayAdapter can simplify the development process, avoiding manually setting the layout and content of each list item one by one, thereby improving development efficiency. Additionally, ArrayAdapter provides common methods such as adding, deleting, and updating data, making it convenient to manipulate the data source.
