  1. POAndroid Xml Handler keeps only the last objects in my xml file
    text
    copied!<p>I have a class named <code>ExampleHandler extends from DefaultHandler</code>.</p> <p>This class reads data from an external xml file (on the web) the structure of this xml file is :</p> <pre><code>&lt;resultsSet&gt; &lt;result&gt; &lt;title&gt;WinRANI Web Services!&lt;/title&gt; &lt;nom&gt;DADI&lt;/nom&gt; &lt;prenom&gt;Morad&lt;/prenom&gt; &lt;adresse&gt;DANS MES REVES&lt;/adresse&gt; &lt;/result&gt; ... &lt;/resultsSet&gt; </code></pre> <p>I've created a class with the same structure of this xml file called <code>ParsedExampleDataSet</code> (it has getters and setters).</p> <p>I've also created an <code>ArrayList</code> which will contain all the 'result' objects but the problem is that when the handler reads all the objects, all items in the <code>ArrayList</code> are the same.</p> <p>Here is my code :</p> <pre><code>package com.example.helloandroid;
