can't change colors

[jackthebeast]

Hi, I'm trying to use this component but I'm actually unable to change any of the colors.

my code:
xml:

<info.hoang8f.android.segmented.SegmentedGroup
                        xmlns:segmentedgroup="http://schemas.android.com/apk/res-auto"
                        android:id="@+id/segmented"
                        android:layout_width="wrap_content"
                        android:layout_height="wrap_content"
                        android:layout_margin="10dp"
                        android:orientation="horizontal"
                        segmentedgroup:sc_border_width="2dp"
                        segmentedgroup:sc_corner_radius="10dp"
                        segmentedgroup:sc_tint_color="#CC0000"
                        segmentedgroup:sc_checked_text_color="#00CC00">

                        <RadioButton
                            android:id="@+id/button21"
                            android:layout_width="wrap_content"
                            android:layout_height="wrap_content"
                            android:text="One"
                            style="@style/RadioButton" />

                        <RadioButton
                            android:id="@+id/button22"
                            android:layout_width="wrap_content"
                            android:layout_height="wrap_content"
                            android:text="Two"
                            style="@style/RadioButton" />
                    </info.hoang8f.android.segmented.SegmentedGroup>

java:

SegmentedGroup segmented = (SegmentedGroup) view.findViewById(R.id.segmented);
segmented.setTintColor(Color.parseColor("#CC0000"));

the component remains blue and white
Am I doing something wrong?

Removing that line solved the problem:

xmlns:segmentedgroup="http://schemas.android.com/apk/res-auto"
