    <p>I am trying to assign relative widths to columns in a ListView that is in a TabHost, using layout_weight as suggested <a href="http://andmobidev.blogspot.com/2010/01/setting-width-of-view-using-percentage.html">here</a>:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;TabHost xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/tabhost" android:layout_width="fill_parent" android:layout_height="fill_parent"&gt; &lt;LinearLayout android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"&gt; &lt;TabWidget android:id="@android:id/tabs" android:layout_width="fill_parent" android:layout_height="wrap_content"/&gt; &lt;FrameLayout android:id="@android:id/tabcontent" android:layout_width="fill_parent" android:layout_height="fill_parent"&gt; &lt;TableLayout android:id="@+id/triplist" android:layout_width="fill_parent" android:layout_height="wrap_content" android:paddingTop="4px"&gt; &lt;TableRow&gt; &lt;ListView android:id="@+id/triplistview" android:layout_width="fill_parent" android:layout_height="wrap_content"/&gt; &lt;/TableRow&gt; &lt;TableRow&gt; &lt;Button android:id="@+id/newtripbutton" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Add Trip"/&gt; &lt;/TableRow&gt; [other tabs ...] </code></pre> <p>My row definition has 4 columns that I would like to size as follows:</p> <pre><code>&lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:weightSum="1.0" android:padding="4px"&gt; &lt;TextView android:id="@+id/rowtripdate" android:layout_weight=".2" android:layout_width="0dip" android:layout_height="wrap_content" android:inputType="date"/&gt; &lt;TextView android:id="@+id/rowodostart" android:layout_weight=".2" android:layout_width="0dip" android:layout_height="wrap_content"/&gt; &lt;TextView android:id="@+id/rowodoend" android:layout_weight=".2" android:layout_width="0dip" android:layout_height="wrap_content"/&gt; &lt;TextView android:id="@+id/rowcomment" android:layout_weight=".4" android:layout_width="0dip" android:layout_height="wrap_content"&gt; </code></pre> <p></p> <p>Unfortunately, it seems to want to fit all the columns into the space that the button occupies, as opposed to the width of the screen. Or maybe there is another constraint that I do not understand. I'd appreciate your help.</p> <p><a href="http://heeroz.com/layoutprob.png">alt text http://heeroz.com/layoutprob.png</a></p>

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).
