Android Uri转File方法(适配android 10以上版本及android 10以下版本)

    public static File uriToFileApiQ(Uri uri, Context context) {
        File file = null;
        if (uri == null) return file;
        //android10以上转换
        if (uri.getScheme().equals(ContentResolver.SCHEME_FILE)) {
            file = new File(uri.getPath());
        } else if (uri.getScheme().equals(ContentResolver.SCHEME_CONTENT)) {
            //把文件复制到沙盒目录
            ContentResolver contentResolver = context.getContentResolver();
            String displayName = System.currentTimeMillis() + Math.round((Math.random() + 1) * 1000)
                    + "." + MimeTypeMap.getSingleton().getExtensionFromMimeType(contentResolver.getType(uri));

            try {
                InputStream is = contentResolver.openInputStream(uri);
                File cache = new File(context.getCacheDir().getAbsolutePath(), displayName);
                FileOutputStream fos = new FileOutputStream(cache);
                FileUtils.copy(is, fos);
                file = cache;
                fos.close();
                is.close();
            } catch (IOException e) {
                e.printStackTrace();
            }
        }
