设置代理：

adb shell settings put global http_proxy ip:port

如：

adb shell settings put global http_proxy 192.168.0.5:8888

移除代理（需三条指令全部执行，部分机型可能需要重启手机才能完全移除代理）：

adb shell settings delete global http_proxy

adb shell settings delete global global_http_proxy_host

adb shell settings delete global global_http_proxy_port

adb reboot
