Android Button Tooltip
<p><img src="http://i.stack.imgur.com/4JzTd.png" alt="iOS implemenatation">
I'm new to Android and I was wondering if is possible to have an Android button element that has an embedded tooltip?  I would like to have an image on the button, that when pressed opens up a dialog/tootip overlay of some sort. So not a hover tooltip, but a clickable element that goes somewhere other than where the button click goes. If someone could guide me as to the best practice for this that would be great!</p>

<pre><code>&lt;LinearLayout android:orientation="vertical"
        android:layout_width="fill_parent" android:layout_height="wrap_content" android:gravity="center" android:paddingLeft="5dip" android:paddingRight="5dip"&gt;

        &lt;Button android:id="@+id/settings_predefined_message_btn"
            android:layout_width="fill_parent"  android:layout_height="wrap_content"
            android:text="@string/settings_predefined_messages"
            android:background="@drawable/selector_longbutton_witharrow" style="@style/ButtonTextStyle"
            android:layout_marginTop="10dip" android:gravity="center" /&gt;
</code></pre>
