What is ListView in Android SDK?

ListView in Android SDK is a view group that displays a list of scrollable items. Each item in the list can be a single line of text, a combination of text and images, or even a complex view. ListViews are used extensively in Android applications to display data in a vertically scrollable format.

To create a ListView, you typically need an adapter, which provides the data to the ListView and creates the views that represent each item in the list. Common adapters include ArrayAdapter and SimpleAdapter.

Here is a simple example of how to implement a ListView in Android:

// MainActivity.java package com.example.listviewexample; import android.os.Bundle; import android.widget.ArrayAdapter; import android.widget.ListView; import androidx.appcompat.app.AppCompatActivity; public class MainActivity extends AppCompatActivity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); ListView listView = findViewById(R.id.myListView); String[] items = {"Item 1", "Item 2", "Item 3", "Item 4", "Item 5"}; ArrayAdapter adapter = new ArrayAdapter<>(this, android.R.layout.simple_list_item_1, items); listView.setAdapter(adapter); } }
