Autour du tracé

Tout d'abord, l'écran principal Il s'agit essentiellement de TabLayout et ViewPager.

-Mise en page de fragmentation stockée dans ViewPager

fragment_sample.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
              android:layout_width="match_parent"
              android:layout_height="match_parent"
