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。

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

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
        }

    }

这招对我很管用:

<item name="android:statusBarColor">@android:color/transparent</item>
<item name="android:navigationBarColor">@android:color/transparent</item>
<item name="android:windowTranslucentStatus">false</item>
<item name="android:windowTranslucentNavigation">false</item>

在顶部布局中使用android:fitsSystemWindows="false"

你只需要进入mainactivity。java

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        Window g = getWindow();
        g.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);

        setContentView(R.layout.activity_main);

    }
