I want to achieve the status bar described in the Material Design guidelines where the color should be 20% darker than the Toolbar. I have set the following styles:
Styles.xml
<item name="android:windowTranslucentStatus">true</item>
Style.xml (v21)
<item name="android:windowTranslucentStatus">true</item>
But I get complete different layouts than expected.
Emulator 4.4
Emulator 5.0.1
Sony Z3 5.0.1
Is there a proper technique to make the Status Bar 20% trasparent (even by code), send the Toolbar and Drawer on back of the Status bar and avoid the usage of FitSystemWindows on Toolbar which stretch all over my screen?
I think this is what you are looking for: https://github.com/jgilfelt/SystemBarTint
Note that it does only work from Android 4.4 (KitKat), there is no way to tint the system bar on Android versions before 4.4.
