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(); //
