Question

content_mail.xml文件将不会打开。我正在尝试为整个android屏幕生成一个ScrollView，用于其中的所有视图。代码如下，这是先前发布的代码的修订版本：

 getInfo(id: number, token: string) {

    let userData = this.http.get<User[]>(`${this.appLogin}` + id + '?token=' + token);
    return this.http.get<User[]>(`${userData}`);
}

以上代码合并了我理解或误解的建议更改。一种建议是删除图像。但是我需要它们。

删除 tools：showIn =“ @ layout / activity_main” ，然后将代码替换为以下代码，并将替换标记</RelativeLayout>替换为</LinearLayout>
