Question

我正在使用android文档：

培训/相机/照相基础

这是实现的代码：

public class CFoto extends AppCompatActivity {

    private ImageView img;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_cfoto);

        img = findViewById(R.id.imageView);

        if (ContextCompat.checkSelfPermission(CFoto.this, Manifest.permission.WRITE_EXTERNAL_STORAGE) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(CFoto.this, Manifest.permission.CAMERA) != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(CFoto.this, new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE, Manifest.permission.CAMERA}, 1000);
        }
    }

    //Create unic name
    String mCurrentPhotoPath;

    private File createImageFile() throws IOException {
        // Create an image file name
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
        String imageFileName = "Backup_" + timeStamp + "_";
        File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
        File image = File.createTempFile(imageFileName, ".jpg", storageDir);

        mCurrentPhotoPath = image.getAbsolutePath();
        return image;
    }

    //take foto
    static final int REQUEST_TAKE_PHOTO = 1;

    public void tomarFoto(View view) {
        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
            File photoFile = null;
            try {
                photoFile = createImageFile();
            } catch (IOException ex) {
            }
            if (photoFile != null) {
                Uri photoURI = FileProvider.getUriForFile(this, "com.example.android.fileprovider", photoFile);
                takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI.toString());
                startActivityForResult(takePictureIntent, REQUEST_TAKE_PHOTO);

            }
        }
    }

    //preview image
    static final int REQUEST_IMAGE_CAPTURE = 1;

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
            Bundle extras = data.getExtras();
            Bitmap imageBitmap = (Bitmap) extras.get("data");
            img.setImageBitmap(imageBitmap);
        }
    }
}

相机正在工作并将照片保存在本地我应该怎么做才能将照片保存到数据库中？在数据库中，我为图像分配了longblob格式数据库是远程的

您可以将照片的路径保存在数据库中，或将其转换为base64，然后保存。我认为这篇文章可以为您提供帮助：Take picture and convert to Base64

如何从相机的基本照片保存在数据库中？
