Android databinding set padding if value is true
<p>I want to be able to to be able to set padding values if a boolean is true. The problem is that Android studio cannot parse the layout because it thinks 2dp is a decimal with a value of 2 and then doesn't know what to do with the p. how do I format this so that it understands i mean 2 density pixels.</p>

<p>Data layout:</p>

<pre><code>&lt;data class=".ItemBinding"&gt;
    &lt;variable name="isGroupType" type="Boolean"/&gt;
&lt;/data&gt;
</code></pre>

<p>View layout(whats important):</p>

<pre><code>&lt;android.support.v7.widget.AppCompatImageView
            android:layout_width="64dp"
            android:layout_height="64dp"
            android:paddingBottom='@{isGroupType ? 2dp : 0dp}'
            android:paddingTop='@{isGroupType ? 8dp : 0dp}'
            android:paddingRight='@{isGroupType ? 2dp : 0dp}'
            android:paddingLeft='@{isGroupType ? 2dp : 0dp}'/&gt;
</code></pre>
