从相机捕获图片时如何修复 NullPointerException: file
How to fix NullPointerException: file when capturing picture from Camera
我正在尝试使用相机拍摄图像，但是在保存文件时出现以下错误：
java.lang.NullPointerException: file

我想直接从相机捕获图像并将其保存到数据库中。如何解决？

我希望在从相机拍摄后直接保存图片。

}
}

Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
thumbnail.compress(Bitmap.CompressFormat.JPEG, 90, bytes);
File destination = new File(Environment.getExternalStorageDirectory(),
System.currentTimeMillis() + ".jpg");
FileOutputStream fo;
try {
destination.createNewFile();
fo = new FileOutputStream(destination);
fo.write(bytes.toByteArray());
fo.close();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
user_image.setImageBitmap(thumbnail);
}
private void onSelectFromGalleryResult(Intent data) {
Bitmap bm = null;
if (data != null) {
try {
bm =
MediaStore.Images.Media.getBitmap(getApplicationContext().getContentResolver(),
data.getData());
} catch (IOException e) {
e.printStackTrace();
}
}
user_image.setImageBitmap(bm);
}
检查数据是否为 !=null 以避免空指针异常
试试这个...
已拍摄图像....
private int REQUEST_IMAGE_CAPTURE = 100;
点击....
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
关于 ActivityResult ....
if (requestCode == REQUEST_IMAGE_CAPTURE && resultCode == RESULT_OK) {
// Bundle extras = data.getExtras();
Bitmap bitmap = ImageUtils.getBitmapFromIntent(this, data);
mImage.setImageBitmap(bitmap);// mImage is a ImageView which is bind previously.
String imgPath = ImageUtils.createFile(this, bitmap);
File imageFile = new File(imgPath);
}
和其他方法....
public class ImageUtils {
public static Bitmap getBitmapFromIntent(Context context,Intent data) {
Bitmap bitmap = null;
if (data.getData() == null) {
bitmap = (Bitmap) data.getExtras().get("data");
} else {
try {
bitmap = MediaStore.Images.Media.getBitmap(context.getContentResolver(), data.getData());
} catch (IOException e) {
e.printStackTrace();
}
}
return bitmap;
}
public static String createFile(Context context, Bitmap data) {
Uri selectedImage = getImageUri(context,data);
String[] filePath = {MediaStore.Images.Media.DATA};
Cursor c = context.getContentResolver().query(selectedImage, filePath, null, null, null);
c.moveToFirst();
c.getColumnIndex(filePath[0]);
int columnIndex = c.getColumnIndex(filePath[0]);
String picturePath = c.getString(columnIndex);
c.close();
return picturePath;
}
public static Uri getImageUri(Context context, Bitmap inImage) {
ByteArrayOutputStream bytes = new ByteArrayOutputStream();
inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
String path = MediaStore.Images.Media.insertImage(context.getContentResolver(), inImage, "Pet_Image", null);
return Uri.parse(path);
}
}
注意：- 您得到的 URI 为空，因为您捕获的图像没有任何路径。所以 URI return 为空..
我在项目中就是这样做的。
public void openCamera() {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
File file = createImageFile();
boolean isDirectoryCreated = file.getParentFile().mkdirs();
Log.d("===PickFragment", "openCamera: isDirectoryCreated: " + isDirectoryCreated);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
Uri tempFileUri = FileProvider.getUriForFile(getActivity().getApplicationContext(),
"com.scanlibrary.provider", // As defined in Manifest
file);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, tempFileUri);
} else {
Uri tempFileUri = Uri.fromFile(file);
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, tempFileUri);
}
startActivityForResult(cameraIntent, ScanConstants.START_CAMERA_REQUEST_CODE);
}
private File createImageFile() {
clearTempImages();
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new
Date());
File file = new File(Environment
.getExternalStorageDirectory().getPath(), "IMG_" + timeStamp +
".jpg");
fileUri = Uri.fromFile(file);
return file;
}
