 判斷是否有網絡連接

public static boolean isNetWorkConnect(Context context){
        //得到網絡連接器
 ConnectivityManager conn = (ConnectivityManager) context.getSystemService(context.CONNECTIVITY_SERVICE);
    NetworkInfo info = conn.getActiveNetworkInfo();
    if(info!=null){
        return true;
    }else{
        return false;
    }

}

//判斷WiFi是否可用
public static boolean isWiFiwork(Context context){

    //得到網絡連接
  ConnectivityManager cm = (ConnectivityManager) context.getSystemService(context.CONNECTIVITY_SERVICE);
    NetworkInfo info = cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
   if(info!=null){
       return info.isAvailable();
   }

    return  false;
}

//判斷流量是否可用
public static boolean isMobileConnected(Context context){
    //得到網絡連接管理器
    ConnectivityManager cm= (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
    NetworkInfo mobile = cm.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
    if (mobile!=null){
        return true;
    }
    return false;
