Java &引用；“镜子”；屏幕视图中的android内置摄像头

我有以下java方法：

private Camera openFrontFacingCameraGingerbread() {
        int cameraCount = 0;
        Camera cam = null;
        Camera.CameraInfo cameraInfo = new Camera.CameraInfo();
        cameraCount = Camera.getNumberOfCameras();
        for (int camIdx = 0; camIdx < cameraCount; camIdx++) {
            Camera.getCameraInfo(camIdx, cameraInfo);
            if (cameraInfo.facing == Camera.CameraInfo.CAMERA_FACING_FRONT) {
                try {
                    cam = Camera.open(camIdx);
                } catch (RuntimeException e) {
                    Toast.makeText(debug, "failed", Toast.LENGTH_LONG).show();
                }
            }
        }

有人能帮我吗？非常感谢您

您需要在版面中包含一个

SurfaceView

，并使用和。这将在您的活动中绘制相机的输入

你应该检查一下，还要看一下

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.activity_main);
        openFrontFacingCameraGingerbread();
    }
