推荐答案
尝试在清单文件的应用程序标记中使用android:usesCleartextTraffic="true"！
由于我在使用Android Volley时遇到同样的问题！
Try Using android:usesCleartextTraffic="true" in Application Tag of your Manifest file!
As i faced same issue using Android Volley!
根据Android文档
As per Android Documentation
指示应用程序是否打算使用明文网络流量，例如明文HTTP.定位到 API级别27或更低的应用的默认值为
"true".定位到 API级别28或更高的应用默认为"false".
Indicates whether the app intends to use cleartext network traffic, such as cleartext HTTP. The default value for apps that target API level 27 or lower is
"true". Apps that target API level 28 or higher default to"false".
当
属性设置为"false"，平台组件(例如，HTTP
和FTP堆栈，DownloadManager，MediaPlayer)将拒绝该应用的
请求使用明文流量.第三方库是强大的
也鼓励您遵守此设置.避免的主要原因
明文流量缺乏机密性，真实性和
防止篡改的保护措施:网络攻击者可以窃听
传输数据，并在未检测到的情况下对其进行修改.

When the
attribute is set to "false", platform components (for example, HTTP
and FTP stacks, DownloadManager, MediaPlayer) will refuse the app's
requests to use cleartext traffic. Third-party libraries are strongly
encouraged to honor this setting as well. The key reason for avoiding
cleartext traffic is the lack of confidentiality, authenticity, and
protections against tampering: a network attacker can eavesdrop on
transmitted data and also modify it without being detected.
