如何检查互联网连接是否在Android中启用?就像如果位置服务被禁用,我们使用的技术如何检查Internet连接(Wifi /移动数据)是否已启用?
Location myLocation = locationmanager.getLastKnownLocation(provider);
if(myLocation == null){
Show the AlertDialog.
}else{
do this.
}
这样,我如何检查Internet连接启用/禁用。

您可以使用下面的方法:
ConnectivityManager conectivtyManager = (ConnectivityManager) ctx.getSystemService(Context.CONNECTIVITY_SERVICE);
if (conectivtyManager.getActiveNetworkInfo() != null
&& conectivtyManager.getActiveNetworkInfo().isAvailable()
&& conectivtyManager.getActiveNetworkInfo().isConnected()) {
isConnected = true;
} else {
isConnected= false;
}
希望它能帮助!
支持WiFi:
ConnectivityManager mgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = mgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
connected = networkInfo != null && networkInfo.isConnected();
移动:
ConnectivityManager mgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = mgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
connected = networkInfo != null && networkInfo.isConnected();
它帮助!谢谢! –
