    <p>In Android Studio, the layout editor cannot preview custom views in xml.</p> <p>Very simple example:</p> <pre><code>public class MyCustomView extends FrameLayout { public MyCustomView(Context context) { super(context); } public MyCustomView(Context context, AttributeSet attrs) { super(context, attrs); } public MyCustomView(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } } </code></pre> <p>&nbsp;</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"&gt; &lt;com.myprojectxxx.view.MyCustomView android:layout_width="48dp" android:layout_height="48dp" /&gt; &lt;/LinearLayout&gt; </code></pre> <p>Android Studio always says,</p> <blockquote> <p>Rendering Problems</p> <p>The following classes could not be found:</p> <ul> <li>com.myprojectxxx.view.MyCustomView (Fix Build Path, Create Class)</li> </ul> <p>Tip: Try to build the project</p> </blockquote> <p>Of course, I HAVE that class. If I click "Create Class", it complains that the same class already exists. If I rebuild that project, nothing changes.</p> <p>And, yes, the project works very well on my Android device. Also, it is rendered very well in Eclipse ADT. However, in Android Studio, it always says that "CLASSES COULD NOT BE FOUND."</p> <p>Android Studio does not have the ability to preview a xml file with custom views? What's wrong with this?</p>

    1. COSO isn't the place to go to get technical support for software in alpha stages. Go to whatever Google has set to discuss problems and explain your error there.

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
