Comment prendre une photo pour montrer dans un ImageView " et " enregistrer l'image?

Vous pouvez invoquer l'Activité de la caméra en ajoutant ces lignes dans votre code :

Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);              
private static int RESULT_IMAGE_CLICK = 1;

                cameraImageUri = getOutputMediaFileUri(1);

                //set the image file name
                intent.putExtra(MediaStore.EXTRA_OUTPUT, cameraImageUri);
                startActivityForResult(intent, RESULT_IMAGE_CLICK);

Maintenant créer le fichier Uri parce que, dans certains téléphones android, vous obtiendrez null données dans return

voici donc la méthode pour obtenir l'image URI :

 /** Create a file Uri for saving an image or video */
        private static Uri getOutputMediaFileUri(int type) {

            return Uri.fromFile(getOutputMediaFile(type));
        }

        /** Create a File for saving an image or video */
        private static File getOutputMediaFile(int type) {

            //Check that the SDCard is mounted
            File mediaStorageDir = new File(
        Environment.getExternalStorageDirectory(), Environment.DIRECTORY_PICTURES);

            //Create the storage directory(MyCameraVideo) if it does not exist
            if (!mediaStorageDir.exists()) {

                if (!mediaStorageDir.mkdirs()) {

                    Log.e("Item Attachment",
                            "Failed to create directory MyCameraVideo.");

                    return null;
                }
            }
java.util.Date date = new java.util.Date();
        String timeStamp = getTimeStamp();

        File mediaFile;

        if (type == 1) {

            //For unique video file name appending current timeStamp with file
            //name
            mediaFile = new File(mediaStorageDir.getPath() + File.separator +abc+ ".jpg");

        } else {
            return null;
        }

        return mediaFile;
    }

Pour récupérer cliqué sur l'image :

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


    //Here you have the ImagePath which you can set to you image view
                    Log.e("Image Name", cameraImageUri.getPath());

         Bitmap myBitmap = BitmapFactory.decodeFile(cameraImageUri.getPath()); 

            yourImageView.setImageBitmap(myBitmap);



//For further image Upload i suppose your method for image upload is UploadImage
File imageFile = new File(cameraImageUri.getPath());
                uploadImage(imageFile);

                        }




            }
        }

Car il n'y a pas de bonne solution pour ce faire, je vais mettre ici ce que j'ai mis en place qui est au travail et de les corriger.

ImageButton takepic = (ImageButton) returnView.findViewById(R.id.takepic);
takepic.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) { Intent intent = new Intent();
addPhoto();
}
});

CreateImageFile Fonction

private File createImageFile() throws IOException {
//Create an image file name
String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
String imageFileName = "JPEG_" + timeStamp + "_";
storageDir = getActivity().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;
}

AddPhoto Fonction

private void addPhoto() {
//Camera.
final List<Intent> cameraIntents = new ArrayList<Intent>();
final Intent captureIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
final PackageManager packageManager = getActivity().getPackageManager();
final List<ResolveInfo> listCam = packageManager.queryIntentActivities(captureIntent, 0);
for(ResolveInfo res : listCam) {
final String packageName = res.activityInfo.packageName;
final Intent intent = new Intent(captureIntent);
intent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
intent.setPackage(packageName);
intent.putExtra(MediaStore.MEDIA_IGNORE_FILENAME, ".nomedia");
cameraIntents.add(intent);
}
//Filesystem.
final Intent galleryIntent = new Intent();
galleryIntent.setType("image/*");
galleryIntent.setAction(Intent.ACTION_GET_CONTENT);
//Chooser of filesystem options.
final Intent chooserIntent = Intent.createChooser(galleryIntent, "profileimg");
//Add the camera options.
chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, cameraIntents.toArray(new Parcelable[]{}));
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(getContext(),
"com.example.android.fileprovider",
photoFile);
chooserIntent.putExtra(MediaStore.EXTRA_OUTPUT, photoURI);
startActivityForResult(chooserIntent, 100);}
}

Sur l'activité de rappel

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == 100) {
try {
Bundle extras = data.getExtras();
Uri uri = data.getData();
ImageButton takepic = (ImageButton) returnView.findViewById(R.id.takepic);
if (extras!=null){
Bitmap imageBitmap = (Bitmap) extras.get("data");
Log.d(TAG, "onActivityResult: "+mCurrentPhotoPath);
takepic.setImageBitmap(imageBitmap);
}
String wholeID = DocumentsContract.getDocumentId(uri);
//Split at colon, use second item in the array
String idx = wholeID.split(":")[1];
String[] column = {MediaStore.Images.Media.DATA};
//where id is equal to
String sel = MediaStore.Images.Media._ID + "=?";
Cursor cursor = getContext().getContentResolver().

column, sel, new String[]{idx}, null);
String filePath = "";

takepic.setImageBitmap(bitmap);
Toast.makeText(getContext(), "Uploading In Progress",
