    <p>I've come across a bit of a weird issue with activities using the Holo Dialog theme (<code>@android:style/Theme.Holo.Dialog</code>) in Ice Cream Sandwich.</p> <p>It seems like they ignore their layouts and fill the entire screen instead of the layout width and height from their XML layouts. The same layouts are working as expecting in Honeycomb, but not on Ice Cream Sandwich.</p> <p><strong>Example:</strong></p> <p>The correct way (Honeycomb) <img src="https://i.stack.imgur.com/hchDc.jpg" alt="enter image description here"></p> <p>The incorrect way (Ice Cream Sandwich) <img src="https://i.stack.imgur.com/Tq6aL.jpg" alt="enter image description here"></p> <p>Both devices are running the exact same version of the application, and are using the exact same layout. Here's the layout in question:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/linearLayout1" android:layout_width="940dp" android:layout_height="600dp" android:layout_margin="10dp" &gt; &lt;GridView android:id="@+id/gridView1" android:layout_width="940dp" android:layout_height="600dp" android:horizontalSpacing="10dp" android:numColumns="3" android:smoothScrollbar="true" android:stretchMode="columnWidth" android:verticalSpacing="10dp" &gt; &lt;/GridView&gt; &lt;/LinearLayout&gt; </code></pre> <p>Any ideas to how this can be solved? A similar issue occurs on my ICS-based Galaxy Nexus, which completely ignore the <code>match_parent</code> tag for height and width. Is the dialog theme broken in ICS?</p> <p><strong>Update:</strong></p> <p>I've done some more testing, and it seems like 894dp of width or less will produce the "correct" look, but if I set the width to 895dp or more, it'll be the incorrect look. The emulator's acting the same way. This is extremely weird...</p> <p><img src="https://i.stack.imgur.com/taGmv.jpg" alt="enter image description here"></p>

    1. COThat does seem weird. This is a shot in the dark, but sometimes I'll experience weird graphical glitches in my app after changing the Build Target. I have no idea why, but cleaning the project will always fix them. Like I said, shot in the dark, but it may be that simple.

    2. COThanks, just tried that again, but didn't seem to have any effect. I've just updated my question again - it seems like it's happening between 894 and 895 dp of width.

    3. COAre your screen shots taken using two separate devices? Your post assumes that this behavior always works correctly on HoneyComb but not on ICS, but is it possible that the problem you are having is entirely dependent on the size of the screen? If not, then you might consider creating two AVDs (one running 3.0 and another running 4.0) with the exact same screen size and testing it with the two to determine if the problem is in fact dependent on the Android SDK version number.

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.
