To display a list, you can include a list view in your layout XML file
A list view is an adapter view that does not know the details, such as type and contents, of the views it contains. Instead, list view requests views on demand from a
ListAdapter
as needed, such as to display new views as the user scrolls up or down.android list view follows the OnItemClickListener code:
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// Get the selected item text from ListView
String selectedItem = (String) parent.getItemAtPosition(position);
// Display the selected item text on TextView
tv.setText("Your favorite : " + selectedItem);
}
});
}
Follows the android list-view item selector example Step by step code:
1.MainActivity.java:
package com.akash.selectlist;
import android.os.Bundle;
import android.app.Activity;
import android.view.View;
import android.widget.AdapterView;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import java.util.ArrayList;
import java.util.Arrays;
import java.util.List;
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// Get reference of widgets from XML layout
ListView lv = (ListView) findViewById(R.id.list_fruit);
final TextView tv = (TextView) findViewById(R.id.text1);
// Initializing a new String Array
String[] fruits = new String[] {
"Mango",
"Orange",
"Pinaple",
"Malay Apple ",
"Mamoncillo",
"Persian lime"
};
// Create a List from String Array elements
List<String> fruits_list = new ArrayList<String>(Arrays.asList(fruits));
// Create a ArrayAdapter from List
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>
(this, android.R.layout.simple_list_item_1, fruits_list);
// Populate ListView with items from ArrayAdapter
lv.setAdapter(arrayAdapter);
// Set an item click listener for ListView
lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
// Get the selected item text from ListView
String selectedItem = (String) parent.getItemAtPosition(position);
// Display the selected item text on TextView
tv.setText("Your favorite : " + selectedItem);
}
});
}
}
2.activity_main.xml:
<RelativeLayout

android:layout_width="match_parent"

<TextView

android:text="Choose your most favorite."
/>
<ListView
android:id="@+id/list_fruit"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@id/text1"
/>
</RelativeLayout>
3.strings.xml:
<resources>
<string name="app_name">Select list</string>
</resources>
4.AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
