如何在SurfaceView/TextureView中使用cameraX？

dependencies {
    def camerax_version = "1.1.0-alpha07"
    implementation "androidx.camera:camera-camera2:$camerax_version"
    implementation "androidx.camera:camera-lifecycle:$camerax_version"
    implementation "androidx.camera:camera-view:1.0.0-alpha21"
}

<androidx.camera.view.TextureView implementation="androidx.camera.view.TextureView" 
    android:id="@+id/textureView"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

val cameraProviderFuture = ProcessCameraProvider.getInstance(context)
cameraProviderFuture.addListener(Runnable {
    val cameraProvider = cameraProviderFuture.get()
    val preview = Preview.Builder().build().also {
        it.setSurfaceProvider(textureView.createSurfaceProvider())
    }
    val cameraSelector = CameraSelector.DEFAULT_BACK_CAMERA
    try {
        cameraProvider.unbindAll()
        cameraProvider.bindToLifecycle(this, cameraSelector, preview)
    } catch (exc: Exception) {
        Log.e(TAG, "Use case binding failed", exc)
    }
}, ContextCompat.getMainExecutor(context))

<uses-permission android:name="android.permission.CAMERA" />
