Android Studio - issues resizing buttons
<p>For some reason I can't manually resize any buttons on the design view using the handles. I can click and drag the handles but when I release, no changes are seen anywhere.</p>

<p>I'm using a relative layout.</p>

<p>Here is the xml for one of the buttons I'm trying to resize:</p>

<pre><code>&lt;Button
    android:text="√"
    android:id="@+id/button15"
    android:background="@drawable/operator_style"
    android:textAllCaps="false"
    android:fontFamily="sans-serif"
    android:textSize="24sp"
    android:textColor="#707070"
    android:layout_alignBaseline="@+id/buttonLog"
    android:layout_alignBottom="@+id/buttonLog"
    android:layout_alignStart="@+id/button8"
    android:elevation="0dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" /&gt;
</code></pre>

<p>And the xml for the button's style and formatting (operator_style):</p>

<pre><code>&lt;selector xmlns:android="http://schemas.android.com/apk/res/android"&gt;
  &lt;item android:state_pressed="true" &gt;
    &lt;shape&gt;
        &lt;solid
            android:color="#00C7FC" /&gt;
        &lt;stroke
            android:width="4dp"
            android:color="#9FEDFF" /&gt;
        &lt;corners
            android:radius="0dp" /&gt;
    &lt;/shape&gt;
&lt;/item&gt;
&lt;item&gt;
    &lt;shape&gt;
        &lt;solid
            android:color="#cccccc" /&gt;
        &lt;corners
            android:radius="0dp" /&gt;
        &lt;elevation
            android:elevation="2dp" /&gt;
    &lt;/shape&gt;
  &lt;/item&gt;
&lt;/selector&gt;
</code></pre>
