    <p>If you want support from lower versions like 2.1 and higher I can propose my way. I always use separate XML layout for tray (footer in your case), for example (<strong>res/layout/tray.xml</strong>):</p> <pre class="lang-xml prettyprint-override"><code>&lt;?xml version="1.0" encoding="utf-8"?&gt; &lt;LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/mainMenu" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="bottom" android:background="#EEEEEE" android:gravity="bottom|fill_horizontal" android:orientation="horizontal" android:padding="5dp" &gt; &lt;ImageView android:id="@+id/addBtn" android:layout_width="50dp" android:layout_height="50dp" android:src="@drawable/add" android:layout_weight="0.2"/&gt; &lt;ImageView android:id="@+id/catalogBtn" android:layout_width="50dp" android:layout_height="50dp" android:src="@drawable/catalog" android:layout_weight="0.2"/&gt; &lt;ImageView android:id="@+id/searchBtn" android:layout_width="50dp" android:layout_height="50dp" android:src="@drawable/search" android:layout_weight="0.2"/&gt; &lt;ImageView android:id="@+id/settingsBtn" android:layout_width="50dp" android:layout_height="50dp" android:src="@drawable/settings" android:layout_weight="0.2"/&gt; &lt;ImageView android:id="@+id/infoBtn" android:layout_width="50dp" android:layout_height="50dp" android:src="@drawable/info" android:layout_weight="0.2"/&gt; &lt;/LinearLayout&gt; </code></pre> <p>And includes it in every <strong>Activity</strong> I need:</p> <pre class="lang-xml prettyprint-override"><code>&lt;include layout="@layout/tray" android:id="@+id/tray" /&gt; </code></pre> <p>After that I can in java code hide/show some buttons in tray by ID, or select some of them with another color ...</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.

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).
