    <p>First of all, I want to ask something, to know if what I'm doing is correct or wrong. I'm developing an interfaze for a car media, wich is supposed to be over the android stock.</p> <p>It won't have fisical buttons, so I've created a menu_layout wich consists on 2 borders, each on one side, with imagebuttos from where you can access to navigator, phone, tuner, etc...</p> <p>Inside this layout, there is a FrameLayout where dinamically I'll add the layout corresponding to what I need (media, navigator, phone...)</p> <p>The main layout so, is a FragmentActivity, and I set the other "activities" as fragments. </p> <p>But is resulting that doing this, I'm loosing some functionallity in some framents, so...</p> <p>Could I define this fragments as FragmentAcitivities? Or they must be Fragment to be able to set the dinamically on the container?</p> <p>I ask this, because one fragment is the PhoneView. This fragment contais the definitions for custom Imagebuttons that act as the dialer. Also, this frament inflates a layout with the editext, imagebuttons, etc... all necesary to define a custom dialer.</p> <p>But when executing, I get this:</p> <p><code>java.lang.ClassCastException: android.widget.Imagebutton</code> at this line:</p> <p><code>button1 = (ImageButton) getActivity().findViewById(R.id.one);</code> when defining the first button of the dialer.</p> <p>So, is this because the fragment can't inflate a layout with this kind of resources??</p> <p><strong>UPDATE -- Code added</strong></p> <p><strong>phone_view.xml</strong></p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" android:baselineAligned="false"&gt;

    1. COis R.id.one an ImageButton? Also you are not inflating. Android had took care of it for you when you call setContentView. Also you are asking that object to your Activity, not to your Fragment

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.
