    <p>I am trying to return 2 different type of views in the BaseAdapter's getView method according to the position .</p> <p>But I am getting ClassCastException. Below is my code:</p> <pre><code>public View getView(final int position, View convertView, ViewGroup parent) { if(position != 5){ WebPageView web; if(convertView == null){ web = new WebPageView(mContext, new Point(parent.getWidth(), parent.getHeight()), parent); } else { web = (WebPageView) convertView; } web.setPage("http://yahoo.com"); return web; }else{ final PageView pageView; if (convertView == null) { pageView = new PageView(mContext); } else { pageView = (PageView) convertView; } return pageView; } } </code></pre> <p>But I am getting always ClassCastException. When I am using WebPageView or PageView alone in getView, I am not getting the exception.</p> <p>Anyone having any idea?</p> <p>Below is my logcat output.</p> <pre><code>10-18 18:03:59.250: E/AndroidRuntime(31390): FATAL EXCEPTION: main 10-18 18:03:59.250: E/AndroidRuntime(31390): java.lang.ClassCastException: com.getit.WebPageView cannot be cast to com.getit.PageView 10-18 18:03:59.250: E/AndroidRuntime(31390): at com.getit.PageAdapter.getView(PageAdapter.java:94) 10-18 18:03:59.250: E/AndroidRuntime(31390): at com.getit.CustomGalleryView.getOrCreateChild(CustomGalleryView.java:467) 10-18 18:03:59.250: E/AndroidRuntime(31390): at com.getit.CustomGalleryView.onLayout(CustomGalleryView.java:422) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.View.layout(View.java:13754) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.ViewGroup.layout(ViewGroup.java:4364) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.widget.RelativeLayout.onLayout(RelativeLayout.java:948) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.View.layout(View.java:13754) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.ViewGroup.layout(ViewGroup.java:4364) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.widget.FrameLayout.onLayout(FrameLayout.java:448) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.View.layout(View.java:13754) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.ViewGroup.layout(ViewGroup.java:4364) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.widget.LinearLayout.setChildFrame(LinearLayout.java:1649) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.widget.LinearLayout.layoutVertical(LinearLayout.java:1507) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.widget.LinearLayout.onLayout(LinearLayout.java:1420) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.View.layout(View.java:13754) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.ViewGroup.layout(ViewGroup.java:4364) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.widget.FrameLayout.onLayout(FrameLayout.java:448) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.View.layout(View.java:13754) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.ViewGroup.layout(ViewGroup.java:4364) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.ViewRootImpl.performLayout(ViewRootImpl.java:1868) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.ViewRootImpl.performTraversals(ViewRootImpl.java:1689) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.ViewRootImpl.doTraversal(ViewRootImpl.java:1000) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.ViewRootImpl$TraversalRunnable.run(ViewRootImpl.java:4214) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.Choreographer$CallbackRecord.run(Choreographer.java:725) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.Choreographer.doCallbacks(Choreographer.java:555) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.Choreographer.doFrame(Choreographer.java:525) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.view.Choreographer$FrameDisplayEventReceiver.run(Choreographer.java:711) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.os.Handler.handleCallback(Handler.java:615) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.os.Handler.dispatchMessage(Handler.java:92) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.os.Looper.loop(Looper.java:137) 10-18 18:03:59.250: E/AndroidRuntime(31390): at android.app.ActivityThread.main(ActivityThread.java:4745) 10-18 18:03:59.250: E/AndroidRuntime(31390): at java.lang.reflect.Method.invokeNative(Native Method) 10-18 18:03:59.250: E/AndroidRuntime(31390): at java.lang.reflect.Method.invoke(Method.java:511) 10-18 18:03:59.250: E/AndroidRuntime(31390): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:786) 10-18 18:03:59.250: E/AndroidRuntime(31390): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:553) 10-18 18:03:59.250: E/AndroidRuntime(31390): at dalvik.system.NativeStart.main(Native Method) </code></pre>

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.
