android自定义相机如何获取原始图片数据

Camera.AutoFocusCallback autoFocusCallback = new Camera.AutoFocusCallback() {

    @Override
    public void onAutoFocus(boolean success, Camera camera) {
        if (isTake) {
            // 点击拍照按钮 对焦 后 拍照
            // 第一个参数 是拍照的声音，未压缩的数据，压缩后的数据

// mCamera.takePicture(null, null, CameraActivity.this);
mCamera.takePicture(new Camera.ShutterCallback() {
@Override
public void onShutter() {

                }
            }, new Camera.PictureCallback() {
                @Override
                public void onPictureTaken(byte[] bytes, Camera camera) {

                }
            }, new Camera.PictureCallback() {
                @Override
                public void onPictureTaken(byte[] data, Camera camera) {
                    isTake = false;
                    setResult(CAMERARESULT, new Intent().putExtra("data", data));
                    finish();
                }
            });
        }

    }
