//检查是否有读取SD卡权限if (ActivityCompat.checkSelfPermission(getActivity(), Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_GRANTED) {    startLoadInner();  //真正装载插件数据} else {  ////请求读取SD卡权限    requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, 0x1);}

/** * 响应申请权限时，用户操作后的动作，判断用户是否答应授权 * @param requestCode * @param permissions * @param grantResults */@Overridepublic void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {    super.onRequestPermissionsResult(requestCode, permissions, grantResults);    if (requestCode == 0x1) {        if (permissions != null && permissions.length > 0) {            for (int i = 0; i < permissions.length; i++) {                String permisson = permissions[i];                int grantResult = grantResults[i];                if (Manifest.permission.READ_EXTERNAL_STORAGE.equals(permisson)) {                    if (grantResult == PackageManager.PERMISSION_GRANTED) {                        startLoadInner();                    } else {                        Toast.makeText(getActivity(), "没有授权，无法使用", Toast.LENGTH_SHORT).show();                    }                }            }            for (String permisson : permissions) {            }        }    }}
