    <p>Yes, you can. It's simple! I do this because legacy (pre API Level 13) systems do not support the newer layout folder filters. Specifically, I need to distinguish QVGA (small) from WQVGA (normal) and other normal resolutions.</p> <p>Just add a variety of layout files to your layout and layout-land folders, e.g.</p> <pre><code>layout my_layout_default.xml my_layout_qvga.xml layout-land my_layout_default.xml my_layout_qvga.xml </code></pre> <p>Then, select the appropriate layout at run time:</p> <pre><code>protected void onCreate(Bundle savedInstanceState) { // Some code that uses DisplayMetrics to determine the screen type ScreenType st = Util.getScreenType(this); super.onCreate(savedInstanceState); setContentView(st == ScreenType.ST_QVGA ? R.layout.my_layout_qvga : R.layout.my_layout_default); // ... </code></pre> <p>You can add a tag to each layout to discover which one was actually loaded, if you like, e.g.</p> <pre><code>&lt;FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/my_root_view" android:tag="st_port_QVGA" FrameLayout flRoot = (FrameLayout)findViewById(R.id.my_root_view); Object objTag = flRoot.getTag(); if (objTag instanceof String) { String strTag = (String)objTag; System.out.println("Tag = " + strTag); } </code></pre> <p>BTW, there's no reason why you cannot combine this technique with the usual resource qualifiers, e.g. add files like my_layout_default.xml to other folders.</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.
