    <p>I think the function you are looking for is android:weightSum. Here is the official reference: <a href="http://developer.android.com/reference/android/widget/LinearLayout.html#attr_android:weightSum" rel="nofollow">http://developer.android.com/reference/android/widget/LinearLayout.html#attr_android:weightSum</a></p> <p>So to expand your table layout to full screen you need to assign a weightSum of 3 to your TableLayout and divide android:layout_weight of 1 to each TableRow. That will give you the desired result.</p> <p>So your xml layout file will look like this:</p> <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:orientation="vertical" &gt; &lt;LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:orientation="horizontal" &gt; &lt;TableLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:weightSum="3" android:gravity="center"&gt; &lt;TableRow android:layout_weight="1"&gt; &lt;Button android:id="@+id/one" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="fill_vertical" android:layout_weight="1" android:gravity="center" android:text="1" /&gt; &lt;Button android:id="@+id/two" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" android:gravity="center" android:text="2" /&gt; &lt;/TableRow&gt; &lt;TableRow android:layout_weight="1"&gt; &lt;Button android:id="@+id/three" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="fill_vertical" android:layout_weight="1" android:gravity="center" android:text="3" /&gt; &lt;Button android:id="@+id/four" android:text="4" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:layout_weight="1" /&gt; &lt;/TableRow&gt; &lt;TableRow android:layout_weight="1"&gt; &lt;Button android:id="@+id/five" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" android:gravity="center" android:text="5" /&gt; &lt;Button android:id="@+id/six" android:text="6" android:layout_width="fill_parent" android:layout_height="fill_parent" android:gravity="center" android:layout_weight="1" /&gt; &lt;/TableRow&gt; &lt;/TableLayout&gt; &lt;/LinearLayout&gt; &lt;/LinearLayout&gt; </code></pre>

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.

SQuiL has stopped working due to an internal error.

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