How to use ListView in an Android app?

ListView is a vital component in Android development that allows you to display a list of scrollable items efficiently. It makes it easy to manage and display a large set of data on the screen. Below is a simple example of how to implement a ListView in an Android app. This example includes an ArrayAdapter to bind the data to the ListView.


        // 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.listView);
                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);
            }
        }

This example demonstrates how to create a simple ListView with predefined items. Make sure to define the corresponding layout in XML and grant the necessary permissions in your AndroidManifest.xml if needed.
