Android判断设备是不是打开WIFI、GPRS数据连接

代码摘要：

import android.content.Context;	import android.net.ConnectivityManager;	import android.net.NetworkInfo;			ConnectivityManager cm;	cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE);	boolean isWifiConnected=cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState() == NetworkInfo.State.CONNECTED ? true : false ;	boolean isGprsConnected=cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE).getState() == NetworkInfo.State.CONNECTED ? true : false ;

需要添加权限：

 <!-- 查询网络状态权限 -->	 <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />	 <!-- 修改手机连接网路状态权限 -->	 <uses-permission android:name="android.permission.MODIFY_PHONE_STATE" />
