Android判断网络是否连接以及连接类型

//1：测试网络连接，true为已连接
private boolean isNetworkAvailable() {
ConnectivityManager connectivityManager
= (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo();
return activeNetworkInfo != null && activeNetworkInfo.isConnected();
}

/:2：判断网络连接类型public boolean isWifi(Context context) {ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);NetworkInfo networkINfo = cm.getActiveNetworkInfo();if (networkINfo == null) {Log.e("net ", "null");//网络未连接} else if (networkINfo != null&& networkINfo.getType() == ConnectivityManager.TYPE_WIFI) {Log.e("net ", "wifi");//连接WiFireturn true;}Log.e("net ", "mobile");//移动网络return false;}

获取网络信息需要在AndroidManifest.xml文件中加入相应的权限。<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
