  1. GDG Location GDG Ratoma Quoi de neuf avec Android ?

    Charles “Chuck” Greb Co-lead GDG Ratoma @ecgreb
  2. GDG Location GDG Ratoma Alors … quoi de neuf? Quoi

    de neuf de «Quoi de Neuf avec Android?» Android 11 Outils Bibliothèques
  3. GDG Location GDG Ratoma UI

  4. GDG Location GDG Ratoma Window Insets • Plus d'informations sur

    les différents types de contenu affichés ◦ Barre d'état, navigation, IME, ...
  5. GDG Location GDG Ratoma WindowInsets // get WindowInsets object from

    listener view.setOnApplyWindowInsetsListener { view, insets -> }
  6. GDG Location GDG Ratoma WindowInsets // get WindowInsets object from

    listener view.setOnApplyWindowInsetsListener { view, insets -> // See if the IME is visible val imeVisible = insets.isVisible((WindowInsets.Type.ime())) }
  7. GDG Location GDG Ratoma WindowInsets // get WindowInsets object from

    listener view.setOnApplyWindowInsetsListener { view, insets -> // See if the IME is visible val imeVisible = insets.isVisible((WindowInsets.Type.ime())) if (imeVisible) { val imeInsets = insets.getInsets(WindowInsets.Type.ime()) // ... } }
  8. GDG Location GDG Ratoma IME Animations • Synchroniser les animations

    du clavier avec les modifications du contenu de l'application ◦ Écouter les changements ▪ ET / OU ◦ Conduire directement l'animation du clavier logiciel
  9. GDG Location GDG Ratoma IME Animations

  10. GDG Location GDG Ratoma editText.setWindowInsetsAnimationCallback(animCallback) val animCallback = object :

    WindowInsetsAnimation.Callback(DISPATCH_MODE_STOP) { override fun onProgress(p0: WindowInsets, p1: MutableList<WindowInsetsAnimation> ): WindowInsets { ... } // Optional overrides override fun onPrepare(animation: WindowInsetsAnimation) { ... } override fun onEnd(animation: WindowInsetsAnimation) { ... } override fun onStart(animation: WindowInsetsAnimation, bounds: WindowInsetsAnimation.Bounds ): WindowInsetsAnimation.Bounds { ... } } IME Animations En écoutant des modifications du clavier
  11. GDG Location GDG Ratoma IME Animations editText.windowInsetsController?. controlWindowInsetsAnimation( WindowInsets.Type.ime(), /*

    animate the keyboard */ -1, /* infinite duration */ linearInterpolator, /* linear motion */ cancellationSignal, /* allows cancellation */ animationControlListener /* ready/cancelled/finished */ ) Animation directe du clavier
