如何在Android CameraX中使用手动对焦？

Question

我试图像在Camera2 API中一样，对CameraX进行手动对焦

在Camera2 API中，我使用以下代码

final CaptureRequest.Builder captureBuilder = mCameraDevice.createCaptureRequest(CameraDevice.TEMPLATE_STILL_CAPTURE); 

captureBuilder.set(CaptureRequest.CONTROL_AF_MODE, CaptureRequest.CONTROL_AF_MODE_OFF); 

captureBuilder.set(CaptureRequest.LENS_FOCUS_DISTANCE, mLensFocusDistance);

可以在Android相机X中完成手动对焦吗？如果是这样，>>

提前感谢

您应该将TouchListener设置为textureView，然后设置焦点：

private fun setUpTapToFocus() {
    textureView.setOnTouchListener { _, event ->
        if (event.action != MotionEvent.ACTION_UP) {
            return@setOnTouchListener false
        }

        val cameraControl = CameraX.getCameraControl(lensFacing)                           
        val factory = TextureViewMeteringPointFactory(textureView)
        val point = factory.createPoint(event.x, event.y)
        val action = FocusMeteringAction.Builder.from(point).build()
        cameraControl.startFocusAndMetering(action)
        return@setOnTouchListener true
    }
}

希望有所帮助
