An Android ListActivity and ListView example

This source code shows a simple example of how to create an Android ListActivity and ListView, using a static array of elements for the list.

My ListActivity class

package com.devdaily.android.twitterclient;

import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.Toast;

public class TwitterClient extends ListActivity
{

  String[] values = { "Stream", "My Lists", "My Searches", "Trends" };

  @Override
  public void onCreate(Bundle savedInstanceState)
  {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.mainmenu);

    // parameters are (Context, layout for the row, and the array of data)
    setListAdapter(new ArrayAdapter<String>(this,
        android.R.layout.simple_list_item_1, values));
  }

  @Override
  protected void onListItemClick(ListView l, View v, int position, long id)
  {
    String item = (String) getListAdapter().getItem(position);
    Toast.makeText(this, item + " selected", Toast.LENGTH_LONG).show();
  }
  
}

My mainmenu.xml file that declares a ListView

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <ListView
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" >
    </ListView>

</LinearLayout>
