仅状态栏透明，而不是导航栏

Question

I want to set a transparent status bar, not a navigation bar.

what I tried

window.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)

But it set Status bar and navigation bar both transparent. I want only Status bar transparent

I also want to set different status bar color based on Fragment, And my navigation drawer is an overriding status bar, like this

Answer 1

Set these properties in your theme:

<item name="android:windowTranslucentStatus">true</item>
<item name="android:windowTranslucentNavigation">true</item>

And in your layout you want to have a transparent status bar, set below attribute:

android:fitsSystemWindows="true"

Answer 2

On Lolipop and above:

window.statusBarColor = ContextCompat.getColor(this, android.R.color.transparent)

And on Marshmallow and above for transparent status with dark icons

window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or View.SYSTEM_UI_FLAG_LIGHT_STATUS_BAR

or transparent status with light icons

window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
