这篇文章将为大家详细讲解有关Android中怎么封装一个网络检测类,文章内容质量较高,因此小编分享给大家做个参考,希望大家阅读完这篇文章后对相关知识有一定的了解。
我们新建一个networkUtils的类
网络是否可用
public static boolean isNetworkAvailable(Context context) {
ConnectivityManager connectivity = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivity == null) {
} else {
NetworkInfo[] info = connectivity.getAllNetworkInfo();
if (info != null) {
for (int i = 0; i < info.length; i++) {
if (info[i].getState() == NetworkInfo.State.CONNECTED) {
return true;
}
}
}
}
return false;
}
Gps是否打开
public static boolean isGpsEnabled(Context context) {
LocationManager locationManager = ((LocationManager) context
.getSystemService(Context.LOCATION_SERVICE));
List<String> accessibleProviders = locationManager.getProviders(true);
return accessibleProviders != null && accessibleProviders.size() > 0;
}
wifi是否打开
public static boolean isWifiEnabled(Context context) {
ConnectivityManager mgrConn = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
TelephonyManager mgrTel = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
return ((mgrConn.getActiveNetworkInfo() != null && mgrConn
.getActiveNetworkInfo().getState() == NetworkInfo.State.CONNECTED) || mgrTel
.getNetworkType() == TelephonyManager.NETWORK_TYPE_UMTS);
}
判断当前网络是否是wifi网络
public static boolean isWifi(Context context) {
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo();
if (activeNetInfo != null
&& activeNetInfo.getType() == ConnectivityManager.TYPE_WIFI) {
return true;
}
return false;
}
判断当前网络是否是3G网络
public static boolean isMonet(Context context) {
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetInfo = connectivityManager.getActiveNetworkInfo();
if (activeNetInfo != null
&& activeNetInfo.getType() == ConnectivityManager.TYPE_MOBILE) {
return true;
}
return false;
}
检测网络
public static boolean checkNet(Context context) {
try {
ConnectivityManager connectivity = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivity != null) {
NetworkInfo info = connectivity.getActiveNetworkInfo();
if (info != null && info.isConnected()) {
if (info.getState() == NetworkInfo.State.CONNECTED) {
return true;
}
}
}
} catch (Exception e) {
return false;
}
return false;
}
