    <p>I have the following code:</p> <pre><code>package com.example.customlistview; import java.io.File; import java.util.ArrayList; import java.util.Date; import android.os.Bundle; import android.os.Environment; import android.app.Activity; import android.text.format.DateFormat; import android.view.Menu; import android.widget.ListView; import android.widget.Toast; public class MainActivity extends Activity { ArrayList&lt;Contact&gt; imageArry = new ArrayList&lt;Contact&gt;(); ContactImageAdapter adapter; File folder; int j = 0; ArrayList&lt;String&gt; FilesInFolder, FileLastModified; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); folder = new File(Environment.getExternalStorageDirectory() + "/tc/"); FilesInFolder = GetFiles(folder.getAbsolutePath()); //Toast.makeText(this, FilesInFolder.toString(), 2000).show(); for (int i = 0; i &lt; *WHATEVER NUMBER OF FILES*.length(); i++) { // //imageArry.add(new Contact(R.drawable.ic_launcher, FILENAME(FROM GETFILES()), FILEMODIFIED DATE(FROM GETFILELM()))); } Toast.makeText(this, Integer.toString(j), 2000).show(); // add image and text in arraylist imageArry.add(new Contact(R.drawable.ic_launcher, "FaceBook", "8/2/2013")); // take this out imageArry.add(new Contact(R.drawable.ic_launcher, "Google", "8/2/2013")); // take this out // add data in contact image adapter adapter = new ContactImageAdapter(this, R.layout.list, imageArry); ListView dataList = (ListView) findViewById(R.id.list); dataList.setAdapter(adapter); } public ArrayList&lt;String&gt; GetFiles(String DirectoryPath) { ArrayList&lt;String&gt; MyFiles = new ArrayList&lt;String&gt;(); File f = new File(DirectoryPath); //f.mkdirs(); File[] files = f.listFiles(); if (files.length == 0) return null; else { for (int i=0; i&lt;files.length; i++) { if (files[i].getName().endsWith(".tol")) { long lastTime = files[i].lastModified(); String fileName = files[i].getName().substring(0, files[i].getName().lastIndexOf(".")); MyFiles.add(fileName); //MyFiles.add(files[i].getName()); if extension is also needed } } } return MyFiles; } public ArrayList&lt;String&gt; GetFileLM(String DirectoryPath) { ArrayList&lt;String&gt; MyFiles = new ArrayList&lt;String&gt;(); File f = new File(DirectoryPath); //f.mkdirs(); File[] files = f.listFiles(); if (files.length == 0) return null; else { for (int i=0; i&lt;files.length; i++) { if (files[i].getName().endsWith(".tol")) { long lastTime = files[i].lastModified(); String dateString = DateFormat.format("MM/dd/yyyy", new Date(lastTime)).toString(); MyFiles.add(dateString); } } } return MyFiles; } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.main, menu); return true; } } </code></pre> <p>I just need some help for the following lines: Instead of using the following line which enters data manually:</p> <pre><code>imageArry.add(new Contact(R.drawable.ic_launcher, "FaceBook", "8/2/2013")); // take this out </code></pre> <p>I would like to accomplish the following:</p> <pre><code>for (int i = 0; i &lt; *number of files in the folder*.length(); i++) { // //imageArry.add(new Contact(R.drawable.ic_launcher, FILENAME(FROM GETFILES()), FILE MODIFIED DATE(FROM GETFILELM()))); } </code></pre> <p>Replace <code>"FaceBook"</code> with the <code>FileName()</code> and <code>"8/2/2013"</code> with <code>GetFileLM()</code> and use a loop so the loop can enter as many files available from the <code>tc</code> using <code>imageArry.add();</code>.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
