我已经编写了代码来访问下面的api并获取namaz计时的相应值,但是onResponse方法没有被调用。我已在android清单文件中授予了Internet权限。我是Android新手,请帮忙。
尽管我在清单文件中提到了“正在安装”应用,但该应用并没有要求互联网许可。

答案 0 :(得分:0)
您需要将request
对象添加到Volley队列(在您的情况下为mQueue
)中,以便执行请求。
示例:
mQueue.add(request);
答案 1 :(得分:0)
Internet权限是常规权限,因此android系统不会询问Internet权限。
您只需拨打此行:
mQueue.add(request);
请求结束。
答案 2 :(得分:0)
在请求末尾的errorListener方法之后添加以下行
mQueue.add("your request type");
