我正在开发Android应用程序，其中我正在从图库和相机中获取图像。对于图库图像，我在onActivityresult上获得了完美的意图值，但是在相机上，当我想为Uri获取intent.getData（）时，它会给出Null值。

我的代码如下：

public void onClick(DialogInterface dialog, int item) {

                         if(item==1){
                         Intent intent = new Intent();
                            intent.setType("image/*");
                            intent.setAction(Intent.ACTION_GET_CONTENT);
                            startActivityForResult(Intent.createChooser(intent,
                                    "Select Picture"), SELECT_PICTURE);
                     }if(item==0){

                            dispatchTakePictureIntent();
                        // open();
                     }else{
                         alert.cancel();
                     }
                     alert.cancel();
                     }
                   });


private void dispatchTakePictureIntent() {
        Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        if (takePictureIntent.resolveActivity(getPackageManager()) != null) {
            startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE);
        }
    }
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            // Uri selectedImageUri1 = data.getData();
            if (requestCode == SELECT_PICTURE) {
                Uri selectedImageUri = data.getData();
                if (Build.VERSION.SDK_INT < 19) {
                    selectedImagePath = getPath(selectedImageUri);

                    Picasso.with(this).load(selectedImageUri).resize(100, 100).transform(new CircleTransform() {
                        @Override
                        public Bitmap transform(Bitmap source) {
                            int size = Math.min(source.getWidth(), source.getHeight());

                            int x = (source.getWidth() - size) / 2;
                            int y = (source.getHeight() - size) / 2;

                            Bitmap squaredBitmap = Bitmap.createBitmap(source, x, y, size, size);
                            if (squaredBitmap != source) {
                                source.recycle();
                            }

                            Bitmap bitmap = Bitmap.createBitmap(size, size, source.getConfig());

                            Canvas canvas = new Canvas(bitmap);
                            Paint paint = new Paint();
                            BitmapShader shader = new BitmapShader(squaredBitmap,
                                    BitmapShader.TileMode.CLAMP, BitmapShader.TileMode.CLAMP);
                            paint.setShader(shader);
                            paint.setAntiAlias(true);

                            float r = size / 2f;
                            canvas.drawCircle(r, r, r, paint);

                            squaredBitmap.recycle();

                            return bitmap;
                        }
                    }).into(image);

                }
            }
            if (requestCode == REQUEST_IMAGE_CAPTURE) {
                Bundle extras = data.getExtras();
                Uri selectedImageUri = data.getData();
                // data.getData() gives null value
                Bitmap imageBitmap = (Bitmap) extras.get("data");
                image.setImageBitmap(imageBitmap);

            }
}
