华为 6.0 系统 以后 关于读取和写入相册的 权限

将一下代码直接 添加到 oncreate里面即可

  // Storage Permissions    final int REQUEST_EXTERNAL_STORAGE = 1;    String[] PERMISSIONS_STORAGE = {            Manifest.permission.READ_EXTERNAL_STORAGE,            Manifest.permission.WRITE_EXTERNAL_STORAGE    };    // Check if we have write permission    int permission = ActivityCompat.checkSelfPermission(context, Manifest.permission.WRITE_EXTERNAL_STORAGE);    if (permission != PackageManager.PERMISSION_GRANTED) {        // We don't have permission so prompt the user        ActivityCompat.requestPermissions(                getActivity(),                PERMISSIONS_STORAGE,                REQUEST_EXTERNAL_STORAGE        );    }    return root;
