Questions tagged [android-adapter]

An Adapter object acts as a bridge between an AdapterView and the underlying data for that view.

An Adapter represents the connection between a View with some kind of data source. Adapters generally come in two flavours: those representing array/list based data and those that represent Cursor based data.

  • The Adapter provides access to the data items.
  • The Adapter is also responsible for making a View for each item in the data set.

See Adapter reference for more information.
