How to migrate to ListView from an older API?

To migrate from an older API to using ListView in your Android application, you need to update your adapters and data sources to leverage the benefits of ListView, which provides a more efficient way of displaying lists of items.

Example Migration to ListView

Below is a simple example demonstrating how to migrate from an older way of handling lists to using ListView. This example assumes you have an array of strings that you want to display in a ListView.

// In your activity or fragment ListView listView = findViewById(R.id.your_list_view); String[] items = {"Item 1", "Item 2", "Item 3", "Item 4"}; // Create an ArrayAdapter using the string array ArrayAdapter adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, items); // Set the adapter to the ListView listView.setAdapter(adapter);
