如果您有自定义uri，请执行以下操作
File file =new File(uri);
Uri newUri = Uri.fromFile(file);
getApplicationContext().getContentResolver().openFileDescriptor(newUri,"r" );
和openAssetFile中的内容提供程序类
pfd = Objects.requireNonNull(getContext()).getContentResolver().openFileDescriptor(
csp.getTrayImageUri(), "r");
然后执行您的工作，而且，如果你有任何查询IB我或评论在这里
