EDIT: la nouvelle bibliothèque de support de conception prend en charge cela et la méthode précédente n'est plus nécessaire.
Cela peut maintenant être réalisé en utilisant la nouvelle bibliothèque de support de conception Android .
Vous pouvez voir l' exemple d'application Cheesesquare de Chris Banes qui présente toutes les nouvelles fonctionnalités.
Méthode précédente:
Puisqu'il n'y a pas de solution complète publiée, voici comment j'ai obtenu le résultat souhaité.
Incluez d' abord un ScrimInsetsFrameLayout dans votre projet.

Ensuite, créez un styleable afin que le insetForegroundpuisse être réglé.
values / attrs.xml
<declare-styleable name="ScrimInsetsView">
<attr name="insetForeground" format="reference|color" />
</declare-styleable>
Mettre à jour le fichier xml de votre activité et assurez - vous android:fitsSystemWindowsest fixé à vrai sur les deux DrawerLayout, ainsi que le ScrimInsetsFrameLayout.
layout / activity_main.xml
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/drawerLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context=".MainActivity">
<!-- The main content view -->
<LinearLayout
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<!-- Your main content -->
</LinearLayout>
<!-- The navigation drawer -->
<com.example.app.util.ScrimInsetsFrameLayout
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/scrimInsetsFrameLayout"
android:layout_width="320dp"
android:layout_height="match_parent"
android:layout_gravity="start"
android:background="@color/white"
android:elevation="10dp"
android:fitsSystemWindows="true"
app:insetForeground="#4000">
<!-- Your drawer content -->
</com.example.app.util.ScrimInsetsFrameLayout>
</android.support.v4.widget.DrawerLayout>
Dans la méthode onCreate de votre activité, définissez la couleur d'arrière-plan de la barre d'état sur la disposition du tiroir.
MainActivity.java
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
// ...
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
mDrawerLayout.setStatusBarBackgroundColor(
getResources().getColor(R.color.primary_dark));
}
Enfin, mettez à jour le thème de votre application pour que le DrawerLayoutsoit derrière la barre d'état.
values-v21 / styles.xml
<style name="AppTheme" parent="Theme.AppCompat.Light.NoActionBar">
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:statusBarColor">@android:color/transparent</item>
</style>
Résultat:
