Android ListView - Fill With Array

java array

*This is a simple ListView tutorial.Here is what we do:

Our MainActivity

This is our main activity. This is our launcher activity. This class will be the entry point to our application.

First we define our package then import other packages via the import statements.

Then we make our class derive from AppCompatActivity.

We will maintain an array which will act as our data source:

 String[] spacecrafts={"Juno","Hubble","Casini","WMAP","Spitzer","Pioneer","Columbia","Challenger","Apollo","Curiosity"};

We will pass this array into our arrayadapetr constructor and set its instance to our ListView:

    ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,spacecrafts);

Let's look at the full source code.

package com.tutorials.hp.listviewarray;

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

public class MainActivity extends AppCompatActivity {

 ListView lv;
 String[] spacecrafts={"Juno","Hubble","Casini","WMAP","Spitzer","Pioneer","Columbia","Challenger","Apollo","Curiosity"};

 protected void onCreate(Bundle savedInstanceState) {

    lv= (ListView) findViewById(;

    ArrayAdapter<String> adapter=new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,spacecrafts);

    lv.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
        Toast.makeText(MainActivity.this, spacecrafts[i], Toast.LENGTH_SHORT).show();



Our XML Layout

This is our main activity's layout. It is our activity_main.xml file.

We use the following elements:

  1. RelativeLayout - Our ViewGroup.
  2. ListView - Our adapterview.
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android=""
