    <p>The solution is in the bottom:</p> <p>I made some classes that i want to use in a listview. They look like this:</p> <pre><code>public class Equipment{ ....code.... } </code></pre> <p>and</p> <pre><code>public class Weapon extends Equipment{ ...More code... } </code></pre> <p>and</p> <pre><code>public class Armor extends Equipment{ ...More code... } </code></pre> <p>As you can see weapon and armor extends equipment. Now i want to use theese classes in the same ArrayAdapter. In my imagination it would be simple as this:</p> <pre><code>public class ShopItemAdapter extends ArrayAdapter&lt;Equipment&gt;{ private List&lt;Equipment&gt; itemList; public ShopItemAdapter(Context context, List&lt;Equipment&gt; itemList) { super(context, android.R.layout.simple_list_item_1, itemList); this.itemList = itemList; this.context = context; } .... CODE .... } </code></pre> <p>But for some reason I may not create an ArrayAdapter Equipment with List Weapon or List Armor.</p> <pre><code>ShopItemAdapter adapter = new ShopItemAdapter(getApplicationContext(), weaponList); </code></pre> <p>This codes gives me the error that ShopItemAdapter(Context, List) is undefined </p> <p>Am I using subclasses in the wrong way or what?</p> <p>My goal is to show a list of armors when clicking on a button and viseversa.</p> <p>Hope my problem is clear. Thanks!</p> <p><em><strong></em> SOLUTION **</strong> So i just needed to change the constructor to receive then cast to List in the super constructor.</p> <pre><code>public class ShopItemAdapter extends ArrayAdapter&lt;Equipment&gt;{ private List&lt;Equipment&gt; itemList; public ShopItemAdapter(Context context, List&lt;? extends Equipment&gt; itemList) { super(context, android.R.layout.simple_list_item_1, (List&lt;Equipment&gt;)itemList); this.itemList = (List&lt;Equipment&gt;)itemList; this.context = context; } .... CODE .... } </code></pre>

    2. COYour idea is correct but the actual implementation maybe not. What is the exact problem?

    3. COWhen creating an adapter i get the error "The constructor ShopItemAdapter(Context, List<Weapon>) is undefined. Do need to create a constructor for every List types? Seems weird as Weapon extends Equipment. :(

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.
