CheckBox doesn't appear in CheckedTextView

Question

When I set up my CheckedTextView, it has no CheckBox. Here is the xml code for it:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="horizontal"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        >
    <CheckedTextView
            android:id="@+id/checkedtext"
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content"
            android:layout_alignParentLeft="true"
            android:checked="false"
            android:textSize="25dp"
            android:textColor="#FFFFFF"
            android:checkMark="@android:attr/checkMark"
            />
