How to use Adapters in an Android app?

Adapters in Android are a powerful component that allows you to connect data sources to views, such as lists or grids. They serve as a bridge between a data source and the user interface component that displays the data. Common types of adapters include ArrayAdapter, SimpleCursorAdapter, and BaseAdapter. In this guide, we will explore how to use an ArrayAdapter to display a list of items in a ListView.

// Step 1: Create a ListView in your activity layout XML <ListView android:id="@+id/my_list_view" android:layout_width="match_parent" android:layout_height="wrap_content" /> // Step 2: Prepare data for the ListView String[] data = {"Item 1", "Item 2", "Item 3", "Item 4", "Item 5"}; // Step 3: Set up the adapter in your Activity ListView listView = findViewById(R.id.my_list_view); ArrayAdapter adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, data); listView.setAdapter(adapter);
