Android进阶篇-判断3G/WIFI/WAP

奥飞火千万电

　　手机上网的方式主要是GRPS/WIFI/WAP三种形式。
　　有的时候，我们需要获取到当前上网的形式。
　　这就需要使用到下面这个函数：



    /**
* 判断联网状态及联网方式
* @param context 当前应用上下文
* @return NO_NETWORK 无可用网路; WIFI 通过wifi方式联网; GRPS 通过GPRS方式联网
* */
public static int theWayOfNetwork(Context context){
ConnectivityManager conn = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
if(conn.getActiveNetworkInfo() == null || (!conn.getActiveNetworkInfo().isAvailable())){
return HttpUtil.NO_NETWORK;
}
if(conn.getNetworkInfo(1).getState() ==  NetworkInfo.State.CONNECTED){
return HttpUtil.WIFI;
}
if(conn.getNetworkInfo(0).getState() ==  NetworkInfo.State.CONNECTED){
String proxyHost = android.net.Proxy.getDefaultHost();
if (proxyHost != null && !proxyHost.equals("")) {
// WAP方式
return HttpUtil.WAP;
}
return HttpUtil.GPRS;
}
return HttpUtil.NO_NETWORK;
}   
　　读取网络状态权限：



    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
　　当当前无网络状态时，跳转进入网络设置界面



startActivity(new Intent(Settings.ACTION_WIRELESS_SETTINGS));
　　判断一串String是否是电话号码：



    /**是否是电话号码
* @param mobile
* @return
* 2012-6-4
*/
public static boolean isPhoneNum(String mobile) {
mobile = mobile.replaceAll("-", "");
if (mobile == null || "".equals(mobile)) {
return false;
}
/**如果有+86开头，则去掉+86*/
if(mobile.startsWith("+86")){
mobile = mobile.substring(3, mobile.length());
}
/**是否完整的手机号码字数：11位*/
if (!mobile.startsWith("1") || mobile.length() != 11) {
return false;
}
List<String> chinaMobile  = Arrays.asList(new String[] {"135","134","136","137","138","182","187","186","188","182","159","158","157","152","151","150","139"}) ;
List<String> chinaUnicom = Arrays.asList(new String[] {"130","131","132","156","155","185","186"}) ;
List<String> chinaHicdma = Arrays.asList(new String[] {"133","153","189","180"}) ;
boolean bolChinaUnicom  = (chinaUnicom.contains(mobile.substring(0,3))) ;
boolean bolChinaMobile1 = (chinaMobile.contains(mobile.substring(0,3))) ;
boolean bolChinaMobile2 = (chinaHicdma.contains(mobile.substring(0,3))) ;
if (bolChinaUnicom || bolChinaMobile1 || bolChinaMobile2)  {
return true  ;
} else {
return false;
}
}
