    <p>I am trying to extend ActivityInstrumentationTestCase2 as follows:</p> <pre><code>public abstract class FooActivityTestCase&lt;T extends Activity&gt; extends ActivityInstrumentationTestCase2&lt;Activity&gt; { public FooActivityTestCase(String pckg, Class&lt;Activity&gt; activityClass) { super(pckg, activityClass); } public void foo(){ ... } } </code></pre> <p>I try to extend <code>FooActivityTestCase</code> like this:</p> <pre><code>public class SpecificFooTestCase extends FooActivityTestCase&lt;MyActivity&gt; { public SpecificFooTestCase() { super("foo.bar", MyActivity.class); // error on this line } } </code></pre> <p>Eclipse gives me the following error in the constructor:</p> <pre><code>The constructor FooActivityTestCase&lt;MyActivity&gt;(String, Class&lt;MyActivity&gt;) is undefined </code></pre> <p>I am pretty sure that the issue is with how I am using generics. When <code>SpecificFooTestCase</code> extends <code>ActivityInstrumentationTestCase2</code> I don't get any errors. Can anybody point out what I am doing wrong?</p> <hr> <p>Kublai Khan's and Michael Myers' suggestions work in conjunction. After I changed <code>FooActivityTestCase</code> to extend <code>ActivityInstrumentationTestCase2&lt;T&gt;</code> and <code>Class&lt;Activity&gt;</code> to <code>Class&lt;T&gt;</code> in the constructor, the classes compile without errors. This is the resulting class (SpecificFooTestCase hasn't changed):</p> <pre><code>public abstract class FooActivityTestCase&lt;T extends Activity&gt; extends ActivityInstrumentationTestCase2&lt;T&gt; { public FooActivityTestCase(String pckg, Class&lt;T&gt; activityClass) { super(pckg, activityClass); } public void foo(){ ... } } </code></pre>

    1. COCan you replace the Class<Activity> parameter with Class<T>? (Without having Android, I'm just guessing.)

    2. COIt looks like `FooActivityTestCase` should extend `ActivityInstrumentationTestCase2<T>` rather than `ActivityInstrumentationTestCase2<Activity>` specifically.

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.
