如何使用 Kotlin 使状态栏以深色文本颜色完全透明

Question

I use Kotlin to create an android app, I would like to know how to make the status bar completely transparent with dark text color with Kotlin I seen the following soltuion but not work for me Dark-text transparent status bar with opaque navigation bar Here's my following code :

   if (VERSION.SDK_INT in 19..20) {
            setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, true)
        }
        if (VERSION.SDK_INT >= 19) {
            window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
        }
        if (VERSION.SDK_INT >= 21) {
            setWindowFlag(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS, false)
            window.statusBarColor = Color.TRANSPARENT
        }

Here's the custom style in style.xml:

<style name="MyStyle" parent="Theme.AppCompat.Light.NoActionBar">
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
    <item name="windowNoTitle">true</item>
    <item name="android:windowLightStatusBar">true</item>
    <item name="android:navigationBarColor">@android:color/black</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
</style>

And my xml code :

<..... android:fitsSystemWindows="true" ....>

 <com.google.android.material.appbar.AppBarLayout
        android:id="@+id/appBarLayout"
        android:layout_width="match_parent"
        android:layout_height="189dp"
        app:elevation="0dp"
        android:theme="@style/MyStyle" ....>

I want to know where's the problem in my code and How can I correct it to get the status bar completely transparent with dark text color

You have to follow three steps.

1. Update your style.xml and main theme

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

2. In your main xml add

   android:fitsSystemWindows="true"

3. In your activity before setcontView add

   if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) { Window w = getWindow(); w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS); }
