Translucent status bar in Android

Question

I am using the following layout (main_activity.xml)

Answer 1

It seems some people have grey status bar instead of transparent. To avoid this problem do the next in your activity:

override fun onCreate(savedInstanceState: Bundle?) {
    ...
    window.apply {
        clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
        addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
        statusBarColor = Color.TRANSPARENT
        decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
    }
}
