What is Adapters in Android SDK?

Adapters in Android SDK are a bridge between an adapter view (like ListView, GridView, Spinner) and the underlying data for that view. They are responsible for providing the data for each item in the adapter view, allowing for dynamic views that can be populated with varying datasets.

There are several types of adapters in Android, including:

  • ArrayAdapter: Used for binding an array of strings to a list view.
  • CursorAdapter: Used to bind data from a database to a view.
  • SimpleAdapter: Used to bind data from a collection of maps to a list view.
  • BaseAdapter: A custom adapter that allows for more complex data binding scenarios.

Here's an example of a simple ArrayAdapter:

<![CDATA[ ArrayAdapter adapter = new ArrayAdapter( this, android.R.layout.simple_list_item_1, myStringArray); ListView listView = findViewById(R.id.my_list_view); listView.setAdapter(adapter); ]]>
