如何在android的ActivityResult()上获取图片的实际大小

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

private static final int REQUEST_IMAGE = 1;

private void openGallery() {
    Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(intent, REQUEST_IMAGE);
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    
    if (requestCode == REQUEST_IMAGE && resultCode == RESULT_OK && data != null) {
        Uri imageUri = data.getData();
        String imagePath = getImagePath(imageUri);
        int imageSize = getImageSize(imagePath);
        // 在这里可以使用获取到的图片路径和大小进行后续操作
    }
}

private String getImagePath(Uri uri) {
    String[] projection = {MediaStore.Images.Media.DATA};
    Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
    if (cursor != null) {
        int columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        String imagePath = cursor.getString(columnIndex);
        cursor.close();
        return imagePath;
    }
    return null;
}

private int getImageSize(String imagePath) {
    if (imagePath != null) {
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFile(imagePath, options);
        return options.outWidth * options.outHeight;
    }
    return 0;
}
