从图库或照相机照片中选择，这些照片不会显示在ImageView中

Question

Camera taken photo or selected photo is not displaying in ImageView . I'm using the following code:

private void attachFile() {
    final CharSequence[] items = {"Camera", "Gallery", "Cancel"};

    AlertDialog.Builder builder;
    builder = new AlertDialog.Builder(mContext);
    builder.setTitle("Add Image");
    builder.setItems(items, new DialogInterface.OnClickListener() {
        @Override
        public void onClick(DialogInterface dialogInterface, int i) {
            if(items[i].equals("Camera")) {

                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
                startActivityForResult(intent, REQUEST_CAMERA);

            } else if (items[i].equals("Gallery")) {

                Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                intent.setType("image/*");
                startActivityForResult(Intent.createChooser(intent,"Select Photo"), SELECT_FILE);

            } else if (items[i].equals("Cancel")) {
                dialogInterface.dismiss();
            }
        }
    });
    builder.show();
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);


    if (requestCode == Activity.RESULT_OK) {
        if (requestCode == REQUEST_CAMERA && data != null) {
            Log.d(TAG, "onActivityResult: done take photo");
            Uri mImageCaptureUri = data.getData();
            imageView.setImageURI(mImageCaptureUri);
            /*Bundle bundle = data.getExtras();
            final Bitmap bitmap = (Bitmap) bundle.get("data");
            mOnphotoSelectedListener.getImageBitmap(bitmap);*/

        } else if (requestCode == SELECT_FILE) {

            Uri selectImageUri = data.getData();
            mOnphotoSelectedListener.getImagePath(selectImageUri);

            //imageView.setImageURI(selectImageUri);
            //Picasso.with(mContext).load(selectImageUri).into(imageView);
            //Picasso.with(this).load(selectImageUri).into(imageView);
        }
    }
}

Used below code inside the onActivityResult

if (requestCode == Activity.RESULT_OK) {
        File user_dp;

        if (requestCode == REQUEST_CAMERA && data != null) {

            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_dp = destination;

            //update_profilepic is ImageView reference
            Picasso.with(getContext()).load(user_dp).into(update_profilepic);


        } else if (requestCode == SELECT_FILE) {
            Bitmap bm = null;
            if (data != null) {
                try {
                    bm = MediaStore.Images.Media.getBitmap(getActivity().getContentResolver(), data.getData());
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }

            //ivImage is image reference
            ivImage.setImageBitmap(bm);

        }
    }
}

我在if语句的第一行上使用了requestCode而不是resultCode。

i have this code i hope it will work for you its correct working i set onclick for ImageProfile and i give to user picture + crop i hope it will work for u

    private void mImage_profileOnclick() {

    int persmissonCheck = ContextCompat.checkSelfPermission(getActivity(), Manifest.permission.CAMERA);
    if (persmissonCheck == PackageManager.PERMISSION_DENIED) {
        Req();
    }else {
        Dialog dialog = new Dialog(getActivity());
        dialog.setContentView(R.layout.dialog_open_device);
        Button pic, gal;
        pic = (Button) dialog.findViewById(R.id.pick);
        gal = (Button) dialog.findViewById(R.id.gallery);

        pic.setOnClickListener(new View.OnClickListener() {

                startActivityForResult(takePicture, 0);
                dialog.cancel();
