如何在Camera2 Api上运行两种不同的预览？

// 初始化相机
CameraManager cameraManager = (CameraManager) getSystemService(Context.CAMERA_SERVICE);
String cameraId = cameraManager.getCameraIdList()[0]; // 选择第一个相机设备

// 创建预览会话
cameraManager.openCamera(cameraId, new CameraDevice.StateCallback() {
    @Override
    public void onOpened(@NonNull CameraDevice camera) {
        // 创建预览请求
        try {
            final CaptureRequest.Builder previewRequestBuilder = camera.createCaptureRequest(CameraDevice.TEMPLATE_PREVIEW);
            previewRequestBuilder.addTarget(surface1); // 设置第一个Surface为预览目标
            camera.createCaptureSession(Arrays.asList(surface1), new CameraCaptureSession.StateCallback() {
                @Override
                public void onConfigured(@NonNull CameraCaptureSession session) {
                    // 开始预览
                    session.setRepeatingRequest(previewRequestBuilder.build(), null, null);
                }
                // 其他回调方法省略...
            }, null);
        } catch (CameraAccessException e) {
            e.printStackTrace();
        }
    }
    // 其他回调方法省略...
}, null);

// 创建第二个预览请求和Surface
Surface surface2 = new Surface(textureView2.getSurfaceTexture());
cameraManager.openCamera(cameraId, new CameraDevice.StateCallback() {
    @Override
    public void onOpened(@NonNull CameraDevice camera) {
        // 创建预览请求
        try {
            final CaptureRequest.Builder previewRequestBuilder = camera.createCaptureRequest(CameraDevice.TEMPLATE_PREVIEW);
            previewRequestBuilder.addTarget(surface2); // 设置第二个Surface为预览目标
            camera.createCaptureSession(Arrays.asList(surface2), new CameraCaptureSession.StateCallback() {
                @Override
                public void onConfigured(@NonNull CameraCaptureSession session) {
                    // 开始预览
                    session.setRepeatingRequest(previewRequestBuilder.build(), null, null);
                }
                // 其他回调方法省略...
            }, null);
        } catch (CameraAccessException e) {
            e.printStackTrace();
        }
    }
    // 其他回调方法省略...
}, null);
