android：设置状态和导航栏颜色

Question

For my activity, i am setting a background color for the window as

window.decorView.setBackgroundResource(R.drawable.background_red)

Now i want the status and navigation to get a darker shade over this background. How can i get this. I tried setting the theme as

`<style name="Theme.OnArrival.AccessControl" parent="Theme.OnArrival.Light">
        <item name="android:windowTranslucentStatus">true</item>
        <item name="android:windowTranslucentNavigation">true</item>

    </style>`

but it doesnt seem to be working for navigation bar. Whats the right way to do it

Answer 1

To programmatically set status bar color use below code:

    Window window = activity.getWindow();
    window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS);
    window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS);
    window.setStatusBarColor(ContextCompat.getColor(activity,R.color.statusbar_color));

Or set colorPrimaryDark in your Theme.
