Android Page de profil Material Design
Je suis nouveau sur Android et la conception de matériel. Quelqu'un pourrait-il m'aider, s'il vous plaît, à me diriger vers tout site Web qui m'aiderait à créer un écran de profil conforme aux instructions de Google en matière de conception de matériel?
J'étais sur le point d'écrire un blog sur cet écran à propos de CoordinatorLayout. Quoi qu'il en soit .. Vous pouvez avoir mon code pleinement fonctionnel .:

Il n'y a pas de tutoriel parfait, mais ce serait un bon point de départ.
Ce tutoriel traite de la gestion du défilement dans les structures de coordinateur: https://guides.codepath.com/Android/Handling-Scrolls-with-CoordinatorLayout
Conception Pour ce faire, regardez ci-dessous xml

app:layout_anchor="@+id/appbar"

</Android.support.design.widget.CoordinatorLayout>
Puis ouvrez votre Activity.Java ajouter le code suivant
toolbar = (Toolbar) findViewById(R.id.anim_toolbar);
setSupportActionBar(toolbar);
collapsingToolbar = (CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
collapsingToolbar.setTitle("ALi Connors");
La barre d'état transparente est prise en charge au niveau 21 ou supérieur de l'API
//put below line is your style.xml.
<item name="Android:windowTranslucentStatus">true</item>
créer un fichier ovel.xml dans un dossier pouvant être dessiné et copier-coller sous le code
//code start
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:Android="http://schemas.Android.com/apk/res/Android"
Android:shape="oval">
