网络

1.向服务器发送http请求
一
publicbooleansendPhoneInfo(Stringpath){
URLurl=null;
try{
url=newURL(path);
HttpURLConnectionconn=(HttpURLConnection)url.openConnection();
conn.setConnectTimeout(5000);
conn.setRequestMethod("GET");
if(conn.getResponseCode()==200){
returntrue;
}
}catch(Exceptione){
e.printStackTrace();
}

returnfalse;
}
二

newThread(){
@Override
publicvoidrun(){
App.isSuccess=sendPhoneInfo(path);
Log.d("czDebug",path);
}
}.start();

2.获取IP地址

publicstaticStringgetLocalIpAddress(){
try
{
for(Enumeration<NetworkInterface>en=NetworkInterface.getNetworkInterfaces();en.hasMoreElements();)
{
NetworkInterfaceintf=en.nextElement();
for(Enumeration<InetAddress>enumIpAddr=intf.getInetAddresses();enumIpAddr.hasMoreElements();)
{
InetAddressinetAddress=enumIpAddr.nextElement();
if(!inetAddress.isLoopbackAddress()&&InetAddressUtils.isIPv4Address(inetAddress.getHostAddress()))
{
returninetAddress.getHostAddress().toString();
}
}
}
}
catch(SocketExceptionex)
{
Log.e("WifiPreferenceIpAddress",ex.toString());
}
returnnull;
}
*依赖httpclient-4.5.2.jar

3.WebView

publicclassWebViewActivityextendsAppCompatActivity{

@Override
protectedvoidonCreate(BundlesavedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_web_view);

//对象
WebViewwebVeiw=(WebView)findViewById(R.id.webview);
Stringurl="http://10.237.32.10";
//设置
webVeiw.setWebViewClient(newWebViewClient(){//本activity中显示
@Override
publicbooleanshouldOverrideUrlLoading(WebViewview,Stringurl){
view.loadUrl(url);
returntrue;
}
});
WebSettingssettings=webVeiw.getSettings();
settings.setJavaScriptEnabled(true);//启用js
//载入
webVeiw.loadUrl(url);
}
}
