XML を使用して Compose をオーバーレイ (他のアプリの上に描画) に挿入しようとすると、次の例外が発生します。

java.lang.IllegalStateException: ViewTreeLifecycleOwner not found from androidx.constraintlayout.widget.ConstraintLayout{d596746 V.E...... ......ID 0,0-0,0}

ただし、(アクティビティで) オーバーレイがなければ、正常に動作します。誰かが解決方法を知っていますか？AppCompat ライブラリを 1.3.0 に更新済みです

私のXMLコード:

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@color/black">
    <androidx.compose.ui.platform.ComposeView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/compose_view"/>
</androidx.constraintlayout.widget.ConstraintLayout>

私のオーバーレイコード:

mParams = WindowManager.LayoutParams(
    WindowManager.LayoutParams.WRAP_CONTENT,
    WindowManager.LayoutParams.WRAP_CONTENT,
    WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
    WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
    PixelFormat.TRANSLUCENT
)
layoutInflater = context.getSystemService(Context.LAYOUT_INFLATER_SERVICE) as LayoutInflater
mView = layoutInflater.inflate(R.layout.power_overlay, null)
mParams!!.gravity = Gravity.CENTER
mWindowManager = context.getSystemService(Context.WINDOW_SERVICE) as WindowManager
mWindowManager.addView(mView, mParams)

For me it was because I had not included the appcompat library and my activity inherited from Activity instead of AppCompatActivity. The problem resolved by adding the library:

implementation("androidx.appcompat:appcompat:1.3.1")

and inheriting from AppCompatActivity:

class MyActivity: AppCompatActivity() {
  ...
}
