I've tried everything I can to achieve this feature but failed, "drawerLayout.setStatusBarBackground()" doesn't work, "android:windowTranslucentStatus:true" doen't work.
Here, first image is all I can do now, and the second one is the desired effect:
Thank you so much.
Problem is that NavigationView extends ScrimInsetsFrameLayout which listens window insets changes and adds dim line to the layout.
The sameScrimInsetsFrameLayout has styleable property insetForeground at least in com.google.android.material:material:1.1.0-alpha07
so if you use:
<item name="android:windowDrawsSystemBarBackgrounds">true</item>
<item name="android:windowTranslucentStatus">true</item>
<item name="android:statusBarColor">@color/transparent</item>
You only need to set that insetForeground to @color/transparent
For example:
<com.google.android.material.navigation.NavigationView
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="match_parent"
app:insetForeground="@color/transparent"/>
Warning:
This will not work if you set android:fitsSystemWindows="true".
Caution: Using this approach means that you have to manage your insets manually since you are using translucent status and not fitting system windws.
