问题描述
我想以编程方式检查 Android 手机/模拟器中是否有互联网连接.因此,一旦我确定存在互联网连接,我就会拨打互联网电话.
I want to check programmatically whether there is an internet connection in Android phone/emulator. So that once I am sure that an internet connection is present then I'll make a call to the internet.
所以它就像嘿模拟器!如果你有互联网连接,那么请打开这个页面,否则 doSomeThingElse();"
So its like "Hey emulator! If you have an internet connection, then please open this page, else doSomeThingElse();"
推荐答案
我自己实现的方法:
/*
* isOnline - Check if there is a NetworkConnection
* @return boolean
*/
protected boolean isOnline() {
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo netInfo = cm.getActiveNetworkInfo();
if (netInfo != null && netInfo.isConnected()) {
return true;
} else {
return false;
}
}
请注意,这是一个 NetworkConnection-Check.如果有 NetworkConnection,它不一定是 InternetConnection.
Be aware of that this is a NetworkConnection-Check. If there is a NetworkConnection it doesn't have to be a InternetConnection.
