判断 wifi 连接是否可用
?
?
?
public boolean isWifiConnect() { ConnectivityManager connManager = (ConnectivityManager) getSystemService(CONNECTIVITY_SERVICE); NetworkInfo mWifi = connManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI); return mWifi.isConnected(); } ?获取 android 的 ip
?
?
public String getLocalIpAddress() { try { for (Enumeration<NetworkInterface> en = NetworkInterface .getNetworkInterfaces(); en.hasMoreElements();) { NetworkInterface intf = en.nextElement(); for (Enumeration<InetAddress> enumIpAddr = intf .getInetAddresses(); enumIpAddr.hasMoreElements();) { InetAddress inetAddress = enumIpAddr.nextElement(); if (!inetAddress.isLoopbackAddress()) { return inetAddress.getHostAddress().toString(); } } } } catch (SocketException ex) { } return null; } ??
enableNetwork ?后要做循环 处理 待 配置好 所有WIFI 信息
?
for (int i = 0; i < 6; i++) { if(isWifiConnect() == false || getLocalIpAddress() == null || getLocalIpAddress() == ""){ sleep(2000); }}或者判断当前 WIFI 的 SSIWifiInfo info = wifi.getConnectionInfo();?
String ssid = info.getSSID();if(!ssid.contains("BroadlinkProv")){ cNewstatus = 0;}?D

如果网络类型 只是 WPA
?
?
?
wc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);?
?
?
获取IP,MASK,DNS等 信息
?
package t3.com;import android.app.Activity;import android.content.Context;import android.os.Bundle;import android.widget.TextView;import android.net.*;import android.net.wifi.WifiManager;import android.text.format.Formatter;public class T3Activity extends Activity { public String s_dns1 ; public String s_dns2; public String s_gateway; public String s_ipAddress; public String s_leaseDuration; public String s_netmask; public String s_serverAddress; TextView info; DhcpInfo d; WifiManager wifii; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); wifii= (WifiManager) getSystemService(Context.WIFI_SERVICE); d=wifii.getDhcpInfo(); s_dns1="DNS 1: "+String.valueOf(d.dns1); s_dns2="DNS 2: "+String.valueOf(d.dns2); s_gateway="Default Gateway: "+String.valueOf(d.gateway); // Formatter.formatIpAddress(d.ipAddress) 方法是将 返回的INT 型 转为 IP 格式 s_ipAddress="IP Address: "+String.valueOf(Formatter.formatIpAddress(d.ipAddress)); //本地IP s_leaseDuration="Lease Time: "+String.valueOf(d.leaseDuration); s_netmask="Subnet Mask: "+String.valueOf(Formatter.formatIpAddress(d.netmask)); //本地mask s_serverAddress="Server IP: "+String.valueOf(d.serverAddress); //dispaly them info= (TextView) findViewById(R.id.tv); info.setText("Network Info\n"+s_dns1+"\n"+s_dns2+"\n"+s_gateway+"\n"+s_ipAddress+"\n"+s_leaseDuration+"\n"+s_netmask+"\n"+s_serverAddress); }}?获取MAC 地址
?
public String getLocalMacAddress() { WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE); WifiInfo info = wifi.getConnectionInfo(); return info.getMacAddress(); } ??
其中 wifiinfo , getConnectionInfo()
wifiinfo.getBSSID()；
wifiinfo.getSSID()；
wifiinfo.getIpAddress()；获取IP地址。
wifiinfo.getMacAddress()；获取MAC地址。
wifiinfo.getNetworkId()；获取网络ID。
wifiinfo.getLinkSpeed()；获取连接速度，可以让用户获知这一信息。
? ? wifiinfo.getRssi()；获取RSSI，RSSI就是接受信号强度指示。在这可以直 接和华为提供的Wi-Fi信号阈值进行比较来提供给用户，让用户对网络或地理位置做出调整来获得最好的连接效果。
? ? 这里得到信号强度就靠wifiinfo.getRssi()；这个方法。
