Vous pouvez simplement suivre les instructions fournies ici: http://Android-developers.blogspot.com/2016/02/Android-support-library-232.html

" En attachant un BottomSheetBehavior à une vue enfant d'un CoordinatorLayout (c'est-à-dire, en ajoutant app: layout_behavior =" Android.support.design.widget.BottomSheetBehavior "), vous obtiendrez automatiquement le contact approprié détection de transition entre cinq états ... "

dans votre mise en page

<include layout="@layout/content_sheet" />

Si vous voulez que le contenu soit effaçable, assurez-vous d’ajouter app:behavior_hideable="true" sur l'étiquette.

dans votre activité, vous pouvez dire:

  BottomSheetBehavior mBottomSheetBehavior = BottomSheetBehavior.from(findViewById(R.id.bottom_sheet));
  mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_HIDDEN);

  findViewById(R.id.button).setOnClickListener(p-> mBottomSheetBehavior.setState(BottomSheetBehavior.STATE_EXPANDED));
