How to display capture image from camera and display in imageview from file path? [duplicate]

Capture Image from Camera and Display in Activity

Closed 6 years ago.
My problem after taking a photo and then createImageFile .. onActivityResult, photo does not appear on img_photo. how to make appear in img_photo ?
img_photo = (ImageView) findViewById(R.id.imgPhoto);
// take a photo from camera
imgBtnCamera = (ImageButton) findViewById(R.id.imgBtnCamera);
imgBtnCamera.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
// Create the File where the photo should go
File photoFile = null;
try {
photoFile = createImageFile();
} catch (IOException ex) {
// Error occurred while creating the File
}
// Continue only if the File was successfully created
if (photoFile != null) {
Uri photoURI = FileProvider.getUriForFile(PhotoSubmitActivity.this,
"com.example.android.fileprovider", photoFile);
takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
}
}
}
});
Create image file
// Create image file
private File createImageFile() throws IOException {
// Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
File storageDir = getExternalFilesDir(Environment.DIRECTORY_PICTURES);
File image = File.createTempFile(
imageFileName, /* prefix */
".jpg", /* suffix */
storageDir /* directory */
);
// Save a file: path for use with ACTION_VIEW intents
mCurrentPhotoPath = image.getAbsolutePath();
return image;
}
onActivityResult
#Override

img_photo.setScaleType(ImageView.ScaleType.CENTER_CROP);
img_photo.setImageBitmap(bitmap);

I attended training on this link Taking Photos Simply

i had same problem too.but i solved it.
#Driyanto Saputro see in my code where i placed a comment for save Captured image in ImageView.
also Note : i am working on Custom Camera not Using Existing Camera.
i paste my code below to Save Captured image in imageView.
public void CaptureImage() {
mCamera.takePicture(null, null, new Camera.PictureCallback() {
private File imageFile;

// Rotate Image
Matrix rotateMatrix = new Matrix();
final Bitmap rotatedBitmap;
if (mCameraId == CAMERA_FACING_FRONT) {
rotateMatrix.postRotate(270);
} else {
rotateMatrix.postRotate(90);
}
rotatedBitmap = Bitmap.createBitmap(originalBitmap, 0, 0, originalBitmap.getWidth(), originalBitmap.getHeight(), rotateMatrix, false);
final File imageFolder;
if (Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED)) {

imageFile = new File(imageFolder.getAbsolutePath() + File.separator + getFileNameCustomFormat() + " " + "Image.jpg");
SavedImagePath = getFileNameCustomFormat() + " " + "Image.jpg";
// imageFile.createNewFile();
} else {
Toast.makeText(getBaseContext(), "Image Not saved", Toast.LENGTH_SHORT).show();
return;
}
ByteArrayOutputStream outputStream = new ByteArrayOutputStream();
// Save image into gallery
if (rotatedBitmap != null) {
rotatedBitmap.compress(Bitmap.CompressFormat.JPEG, 90, outputStream);
}
FileOutputStream file_out = new FileOutputStream(imageFile);
file_out.write(outputStream.toByteArray());
file_out.close();
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.DATE_TAKEN, System.currentTimeMillis());
values.put(MediaStore.Images.Media.MIME_TYPE, "image/jpeg");

The Image Editor developer guide currently says that you should pass a Uri to withOutput(), but this is incorrect.
Try passing a File:
/* 1) Change the argument to your desired location */
File file = new File(Environment.getExternalStorageDirectory() + File.separator + "test.jpg");
try {
file.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
Intent imageEditorIntent = new AdobeImageIntent.Builder(this)
.setData(imageUri)
.withOutput(file) /* 2) Pass the File here */
.build();
Your argument to the File constructor should be altered to whatever location you desire.

Capturing and storing multiple images in android [duplicate]

I seem to be having trouble creating a Bitmap from fileUri.
I would like to be able to set this Bitmap to an Imageview for previewing the image, and later adding elements to the image.
Any ideas why the image does not get set properly?

Why can't some images be displayed on ImageView (Android)?

When I pick an image from my gallery, screenshots are shown but some images taken from camera aren't shown.
To be more specific, images taken using the system Camera app can't be shown while the ones taken using Camera360 can.
I wonder if there's any problem with my code. If there isn't, maybe it's because of my phone?
Thanks in advance. Sorry, my English isn't very good.
