如何拍照，但不能OCR：android studio

Question

我组合了两个Java代码，但有一个问题：当我拍照然后我想用这张照片读取文本时，它会写入程序分配的图像的文本（不是拍摄的照片）。

问题是命令的组合，我无法排序。始终读取原始图像（ImageView 随 Bitmap 测试图像一起安装）。 我尝试了很多次但无法订购。

PS 我不想保存捕获的图像。

预先感谢您的反馈。

我的Java代码：

    public class MainActivity extends AppCompatActivity {

    private static final int CAMERA_REQUEST = 1888; ///////
    private ImageView imageView;///
    private static final int MY_CAMERA_PERMISSION_CODE = 100;////


    ////////////
    @Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults)
    {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        if (requestCode == MY_CAMERA_PERMISSION_CODE)
        {
            if (grantResults[0] == PackageManager.PERMISSION_GRANTED)
            {
                Toast.makeText(this, "camera permission granted", Toast.LENGTH_LONG).show();
                Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(cameraIntent, CAMERA_REQUEST);
            }
            else
            {
                Toast.makeText(this, "camera permission denied", Toast.LENGTH_LONG).show();
            }
        }
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == CAMERA_REQUEST && resultCode == Activity.RESULT_OK) {
