它只是移除statusBar的颜色!

window?.decorView?.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
window?.statusBarColor = Color.TRANSPARENT

这招对我管用，希望对你也管用

你所需要做的就是在你的主题中设置这些属性:

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

你的活动/容器布局，你希望有一个透明的状态栏需要这个属性集:

android:fitsSystemWindows="true"

这通常是不可能执行这肯定在预kitkat，看起来你可以这样做，但一些奇怪的代码使它如此。

编辑:我推荐这个lib: https://github.com/jgilfelt/SystemBarTint为许多前棒棒糖状态栏颜色控制。

经过深思熟虑，我了解到完全禁用状态栏和棒棒糖导航栏上的半透明或任何颜色的答案是在窗口上设置这个标志:

// In Activity's onCreate() for instance
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);
}

没有其他主题是必要的，它产生如下内容:

 <item name="android:statusBarColor" tools:targetApi="lollipop">@android:color/transparent</item>
            <!--<item name="android:windowLightStatusBar" tools:targetApi="m">true</item>-->

不要使用windowLightStatusBar，而是使用statusBarColor = @android:color/transparent

用于谷歌的最后一次更新。这是我的代码。这将是透明的状态栏和导航栏: 把你的主题改为:

 <style name="Theme.Pink" 
 parent="Theme.MaterialComponents.DayNight.NoActionBar">
    <!-- Primary brand color. -->
    <item name="colorPrimary">@color/pink_primary</item>
    <item name="colorPrimaryVariant">@color/pink_dark</item>
    <item name="colorOnPrimary">@color/black</item>
    <!-- Secondary brand color. -->
    <item name="colorSecondary">@color/pink_light</item>
    <item name="colorSecondaryVariant">@color/pink_primary</item>
    <item name="colorOnSecondary">@color/black</item>
    <item name="android:textColor">?attr/colorOnPrimary</item>
    <!-- Status bar color. -->
    <!-- Customize your theme here. -->
 //transparent statusbar
    <item name="android:windowTranslucentStatus">true</item>
    <item name="android:windowIsTranslucent">true</item>
//transparent navigationbar
    <item name="android:windowTranslucentNavigation">true</item> 
 </style>

然后在layout (file xml)中:添加2个属性point_top和point_bottom来确定应用程序其他组件的边距值的位置:

    <androidx.constraintlayout.widget.ConstraintLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@drawable/bg_activity">

    <TextView
        android:id="@+id/point_top"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    

    <TextView
        android:id="@+id/point_bottom"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent" />
   
       <.....>

   </androidx.constraintlayout.widget.ConstraintLayout>

然后在baseActivity或yourActivity中:在onCreate中添加以下代码:

 override fun onCreate(savedInstanceState: Bundle?) {
   
    super.onCreate(savedInstanceState)
    binding = setLayout()
    //set inset for view
    ViewCompat.setOnApplyWindowInsetsListener(binding.root) { _, insets ->
        val paramsTop =
            findViewById<TextView>(R.id.point_top).layoutParams as MarginLayoutParams
        paramsTop.setMargins(0, insets.getInsets(WindowInsetsCompat.Type.systemBars()).top, 0, 0)
        findViewById<TextView>(R.id.point_top).layoutParams = paramsTop
        val paramsBottom =
            findViewById<TextView>(R.id.point_bottom).layoutParams as MarginLayoutParams
        paramsBottom.setMargins(0, 0, 0, insets.getInsets(WindowInsetsCompat.Type.systemBars()).bottom)
        findViewById<TextView>(R.id.point_bottom).layoutParams = paramsBottom
        insets.consumeSystemWindowInsets()

    }

    setContentView(binding.root)
}

希望这对大家有所帮助。

这是一个简单的方法，我找到了很多搜索。

步骤1

在你的主题里放这个项目

        <item name="android:statusBarColor" tools:targetApi="lollipop">@android:color/transparent</item>

步骤2

主要活动

WindowCompat.setDecorFitsSystemWindows(window, false)

非常重要，如果你使用底部导航栏

在一些设备中，API 30+ u会发现系统导航栏与底部导航栏重叠，如果在你的应用中使用它。

这就解决了这个问题。

  if (Build.VERSION.SDK_INT >= 30) {
        // Root ViewGroup of my activity
        val root = findViewById<ConstraintLayout>(R.id.root)

        ViewCompat.setOnApplyWindowInsetsListener(root) { view, windowInsets ->

            val insets = windowInsets.getInsets(WindowInsetsCompat.Type.systemBars())

            // Apply the insets as a margin to the view. Here the system is setting
            // only the bottom, left, and right dimensions, but apply whichever insets are
            // appropriate to your layout. You can also update the view padding
            // if that's more appropriate.

            view.layoutParams =  (view.layoutParams as FrameLayout.LayoutParams).apply {
                leftMargin = insets.left
                bottomMargin = insets.bottom
                rightMargin = insets.right
            }

            // Return CONSUMED if you don't want want the window insets to keep being
            // passed down to descendant views.
            WindowInsetsCompat.CONSUMED
        }

    }

下面是kotlin中的一个扩展，它可以做到这一点:

fun Activity.setTransparentStatusBar() {
    window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_STABLE or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
        window.statusBarColor = Color.TRANSPARENT
    }
}
