    <p>I am currently trying to implement a Spinner within my android application. I am having trouble with getting the OnItemSelected method, to open a new class based on what item was selected. </p> <p>I have the code shown bellow, which does not seem to work, Also since adding this is, it now from the menu when I click the button to open Film and TV it opens the wrong layout, but nothing changed other than adding the bellow code.</p> <p>What should happen: Activity Starts --> Click on Film and TV --> Select item from Spinner --> New class opens based on what Item was selected.</p> <p>What Happens now: Activity Starts --> Click on Film and TV --> Wrong layout opens --> Press back on phone --> Right layout opens --> Select item from Spinner --> Nothing Happens</p> <p>Code: </p> <pre><code>String classes[] = {"SeanConnery", "BillyConnoly", "JamesMcAvoy", "KarenGillan", "KellyMacdonald", "AshleyJensen"}; @Override public void onItemSelected(AdapterView&lt;?&gt; parent, View view, int pos, long id) { String classSpot = classes[pos]; try{ Class nextClass = Class.forName("com.example.famouspeople." + classSpot); Intent ourIntent = new Intent(Film.this, nextClass); startActivity(ourIntent); } catch(ClassNotFoundException e){ e.printStackTrace(); } } </code></pre> <p>Manifest:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.famouspeople" android:versionCode="1" android:versionName="1.0" &gt; &lt;uses-sdk android:minSdkVersion="8" android:targetSdkVersion="17" /&gt; &lt;application android:allowBackup="true" android:icon="@drawable/ic_launcher" android:label="@string/app_name" android:theme="@style/AppTheme" &gt; &lt;activity android:name="com.example.famouspeople.MainMenu" android:label="@string/app_name" &gt; &lt;intent-filter&gt; &lt;action android:name="android.intent.action.MAIN" /&gt; &lt;category android:name="android.intent.category.LAUNCHER" /&gt; &lt;/intent-filter&gt; &lt;/activity&gt; &lt;activity android:name="com.example.famouspeople.Film" android:label="@string/app_name" &gt; &lt;/activity&gt; &lt;activity android:name="com.example.famouspeople.SeanConnery" android:label="@string/app_name" &gt; &lt;/activity&gt; &lt;activity android:name="com.example.famouspeople.BillyConnoly" android:label="@string/app_name" &gt; &lt;/activity&gt; &lt;activity android:name="com.example.famouspeople.JamesMcAvoy" android:label="@string/app_name" &gt; &lt;/activity&gt; &lt;activity android:name="com.example.famouspeople.KarenGillan" android:label="@string/app_name" &gt; &lt;/activity&gt; &lt;activity android:name="com.example.famouspeople.AshleyJensen" android:label="@string/app_name" &gt; &lt;/activity&gt; &lt;activity android:name="com.example.famouspeople.KellyMacdonald" android:label="@string/app_name" &gt; &lt;/activity&gt; &lt;/application&gt; </code></pre> <p></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).
