android - 无法从 android 7.1 及以上设备的图库中选择图像

Question

我正在尝试从图库中选择图像，它在 android 7.1 以下运行良好，但在 android 7.1 中它对我不起作用。一样的怎么修。 这是我试过的代码:

public void LaunchGalleryView() {
        mFileUri = null;
        Intent intent = new Intent(Intent.ACTION_PICK,
                android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        intent.setType("image/*");
        startActivityForResult(Intent.createChooser(intent, "Select Picture"), REQUEST_CODE_GALLERY);
    }

这是 onActivityResult() 中的代码:

 case REQUEST_CODE_GALLERY:
                if (data == null) {
                    return;
                }
                Uri selectedImage = data.getData();
                String[] filePathColumn = {MediaStore.Images.Media.DATA};
                Cursor cursor = getContentResolver().query(selectedImage,
                        filePathColumn, null, null, null);
                cursor.moveToFirst();
                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                String picturePath = cursor.getString(columnIndex);
                cursor.close();

                File file = new File(picturePath);
                mFileUri = FileProvider.getUriForFile(this, this.getApplicationContext().getPackageName() + ".provider", file);
                performCrop();
                break;

如何解决同样的问题，请帮助我。

1. 将图片路径与其他手机图片选择的路径进行比较，有时路径格式可能不同，所以会得到null。
