AutoCompleteTextView with Custom Adapter Part 2 – ARRAY ADAPTER AND FILTER – Android Studio Tutorial
In part 2 of the Custom AutoCompleteTextView Tutorial, we will create our custom ArrayAdapter, which will be the bridge between our ArrayList of custom objects and the AutoCompleteTextView suggestion list.
For this we will extend the ArrayAdapter class, because it already implements the Filterable and ListAdapter interfaces, and implement our own Filter, where we override the performFiltering, publishResults and convertResultToString methods.
In our ArrayAdapter itself we set this filter in the getFilter method and populate our custom row layout in the getView method.
Lastly we create an instance of our adapter in the MainActivity and set it on our AutoCompleteTextView.
