		maven { url 'https://jitpack.io' }
	}
}

Step 2. Add the dependency

 dependencies {
     compile 'com.jyn.marqueeview:marqueetextview:1.0.0'
}

Demo

    <com.jyn.marqueetextview.MarqueeView
        android:id="@+id/marquee"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        app:spacing="0dp"
        app:speed="1"
        app:textColor="@android:color/white"
        app:textSize="15sp">

    </com.jyn.marqueetextview.MarqueeView>

attr

 <declare-styleable name="MarqueeView">
       <attr name="textSize" format="dimension" />
       <attr name="textColor" format="color" />
