Android判断设备是否打开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" />
