5.申请授权（可组合申请）接上文

 let p: Permissions[] = ['ohos.permission.ACTIVITY_MOTION', 'ohos.permission.CAMERA','ohos.permission.LOCATION', 'ohos.permission.APPROXIMATELY_LOCATION'];PermissionUtil.requestPermissions(p).then((grant) => {     if (grant) {       ToastUtil.showToast(`申请授权，已通过...`);     }})

复制代码

如果第一次申请用户没有同意，可二次申请

PermissionUtil.requestPermissionOnSettingEasy(p).then((result) => {   ToastUtil.showToast(`申请授权，结果：${result}`);});

复制代码

6.申请授权，拒绝后可二次申请

let p: Permissions[] = ['ohos.permission.ACTIVITY_MOTION', 'ohos.permission.CAMERA', 'ohos.permission.LOCATION', 'ohos.permission.APPROXIMATELY_LOCATION'];PermissionUtil.requestPermissionsEasy(p).then((result) => {    ToastUtil.showToast(`申请授权，结果：${result}`);})

7.完整 UI 代码
