Try the below answer to populate listview using ArrayList 

<pre><code>public class ExampleActivity extends Activity
{
 ArrayList&lt;String&gt; movies;

 public void onCreate(Bundle saveInstanceState)
 {
 super.onCreate(saveInstanceState);
 setContentView(R.layout.list);

 // Get the reference of movies
 ListView moviesList=(ListView)findViewById(R.id.listview);

 movies = new ArrayList&lt;String&gt;();
 getMovies();

 // Create The Adapter with passing ArrayList as 3rd parameter
 ArrayAdapter&lt;String&gt; arrayAdapter = 
 new ArrayAdapter&lt;String&gt;(this,android.R.layout.simple_list_item_1, movies);
 // Set The Adapter
 moviesList.setAdapter(arrayAdapter); 

 // register onClickListener to handle click events on each item
 moviesList.setOnItemClickListener(new OnItemClickListener()
 {
 // argument position gives the index of item which is clicked
 public void onItemClick(AdapterView&lt;?&gt; arg0, View v,int position, long arg3)
 {
 String selectedmovie=movies.get(position);
 Toast.makeText(getApplicationContext(), "Movie Selected : "+selectedmovie, Toast.LENGTH_LONG).show();
 }
 });
 }

 void getmovies()
 {
 movies.add("X-Men");
 movies.add("IRONMAN");
 movies.add("SPIDY");
 movies.add("NARNIA");
 movies.add("LIONKING");
 movies.add("AVENGERS"); 
 }
}
</code></pre>

Here's an example of how you could implement a list view:

<pre><code> @Override
protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);
 setContentView(R.layout.activity_main);

 //We have our list view
 final ListView dynamic = findViewById(R.id.dynamic);

 //Create an array of elements
 final ArrayList&lt;String&gt; classes = new ArrayList&lt;&gt;();
 classes.add("Data Structures");
 classes.add("Assembly Language");
 classes.add("Calculus 3");
 classes.add("Switching Systems");
 classes.add("Analysis Tools");

 //Create adapter for ArrayList
 final ArrayAdapter&lt;String&gt; adapter = new ArrayAdapter&lt;&gt;(this,android.R.layout.simple_list_item_1, classes);

 //Insert Adapter into List
 dynamic.setAdapter(adapter);

 //set click functionality for each list item
 dynamic.setOnItemClickListener(new AdapterView.OnItemClickListener() {
 @Override
 public void onItemClick(AdapterView&lt;?&gt; parent, View view, int position, long id) {
 Log.i("User clicked ", classes.get(position));
 }
 });



}
</code></pre>

blocks|key|779664|text|首先，我创建了对象|type|unstyled|depth|inlineStyleRanges|entityRanges|data|779665|ListView+listview;
ArrayAdapter+arrayAdapter;
ArrayList<Albums>+listAlbums;|code-block|syntax|javascript|779666|然后在Create方法上：|779667|listview+=+findViewById(R.id.listviewAlbum);
listAlbums+=+new+ArrayList<Albums>();
arrayAdapter+=+new+ArrayAdapter(this,+android.R.layout.simple_list_item_1,+
listAlbums);
listview.setAdapter(arrayAdapter);|779668|然后，如果你使用的是API，你可以使用下面的代码来访问数据集：|779669|for+(Albums+albumaux+:+response.body())+{
+++++++listAlbums.add(albumaux);
++++++++++++}
+++++++arrayAdapter.notifyDataSetChanged();|779670|entityMap^0|0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|Q|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|S|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|T|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|U|8|@]|9|@]|A|$]]|$1|M|3|N|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|O|3|-4|5|6|7|W|8|@]|9|@]|A|$]]]|P|$]]

First I created the objects
<pre><code>ListView listview;
ArrayAdapter arrayAdapter;
ArrayList&lt;Albums&gt; listAlbums;
</code></pre>
Then on On Create method:
<pre><code>listview = findViewById(R.id.listviewAlbum);
listAlbums = new ArrayList&lt;Albums&gt;();
arrayAdapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, 
listAlbums);
listview.setAdapter(arrayAdapter);
</code></pre>
And then if u are using an API u can use this code to get trough the dataset:
<pre><code>for (Albums albumaux : response.body()) {
 listAlbums.add(albumaux);
 }
 arrayAdapter.notifyDataSetChanged();
</code></pre>

My <code>Android</code> app needs to populate the <code>ListView</code> using the data from an <code>ArrayList</code>. 

I have trouble doing this. Can someone please help me with the code?
