I have added the primary dark color on the status bar to make it the color of my toolbar.
But I have a slide up panel with an image on the top (screenshot) which I need to overlay onto the status bar. Its currently like the screenshot below.
Put the below in your AppTheme style in values-v21 folder (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>
By default, the status bar color is determined by "colorPrimaryDark". Apply the above theme to your specific activity in androidManifest.xml. (parent theme can be anything)
