Android中判断网络是否连接实例详解
在android中，如何监测网络的状态呢，这个有的时候也是十分重要的，方法如下：
public class ConnectionDetector {
private Context _context;
public ConnectionDetector(Context context){
this._context = context;
}
public boolean isConnectingToInternet(){
ConnectivityManager connectivity = (ConnectivityManager) _context.getSystemService(Context.CONNECTIVITY_SERVICE);
if (connectivity != null)
{
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;
}
调用：
ConnectionDetector cd = new ConnectionDetector(getApplicationContext()); Boolean isInternetPresent = cd.isConnectingToInternet(); //
