    <p>I'm working on eclipse to develop an android app, I'm testing some code to see how it works but there are some errors which I try to solve them but I could't. I'm new to mobile development and I have to develop a to-do list . the problem is I'm not familiare with adapter and listView so I'm trying to understand them.</p> <p>Java Code</p> <pre><code> package com.example.test; import android.os.Bundle; import android.app.Activity; import android.view.Menu; import android.widget.AdapterView; import android.widget.ArrayAdapter; import android.widget.ListView; public class SimpleListItem1Activity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.simple_list_item1); ListView listView = (ListView) findViewById(R.id.mylist); ArrayAdapter&lt;String&gt; adapter = new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, android.R.id.text1, values); listView.setAdapter(adapter); } @Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.simple_list_item1, menu); return true; } ListView listView = (ListView) findViewById(R.id.mylist); String[] values = new String[] { "Android", "iPhone", "WindowsMobile", "Blackberry", "WebOS", "Ubuntu", "Windows7", "Max OS X", "Linux", "OS/2" }; // Define a new Adapter // First parameter - Context // Second parameter - Layout for the row // Third parameter - ID of the TextView to which the data is written // Forth - the Array of data ArrayAdapter&lt;String&gt; adapter = new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, android.R.id.text1, values); } </code></pre> <p>XML</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" &gt; &lt;ListView android:id="@+id/mylist" android:layout_width="match_parent" android:layout_height="wrap_content" &gt; &lt;/ListView&gt; &lt;/LinearLayout&gt; </code></pre> <p>LogCat</p> <pre><code> 03-14 14:57:07.643: E/AndroidRuntime(773): ... 11 more [2013-03-14 17:54:54 - test] ------------------------------ [2013-03-14 17:54:54 - test] Android Launch!

Guidance
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.

SQuiL has stopped working due to an internal error.

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