判断Wifi是否连接成功，很简单（需要用到广播），

发送一个广播，filter.addAction("android.net.conn.CONNECTIVITY_CHANGE");

接收广播

if(intent.getAction().equals("android.net.conn.CONNECTIVITY_CHANGE")){                WifiSupport.getList(getContext(), list , -1);;//获取数据                adapter.notifyDataSetChanged();                if(WifiSupport.isWifiContected(getContext()) == 1){                    Toast.makeText(getContext(), "连接成功"  + netConnectingid, Toast.LENGTH_SHORT).show();                }else if(WifiSupport.isWifiContected(getContext()) == 2){                    Toast.makeText(getContext(), "正在连接中"  + netConnectingid, Toast.LENGTH_SHORT).show();                }else{                    Toast.makeText(getContext(), "网络变化了3", Toast.LENGTH_SHORT).show();                }            }

下面是判断是否连接

public static final int WIFI_CONNECTED = 0x01;    public static final int WIFI_CONNECT_FAILED = 0x02;    public static final int WIFI_CONNECTING = 0x03;    /**     * 判断wifi是否连接成功,不是network     *     * @param context     * @return     */    public static int isWifiContected(Context context) {        ConnectivityManager connectivityManager = (ConnectivityManager) context                .getSystemService(Context.CONNECTIVITY_SERVICE);        NetworkInfo wifiNetworkInfo = connectivityManager                .getNetworkInfo(ConnectivityManager.TYPE_WIFI);        Log.v(TAG, "isConnectedOrConnecting = " + wifiNetworkInfo.isConnectedOrConnecting());        Log.d(TAG, "wifiNetworkInfo.getDetailedState() = " + wifiNetworkInfo.getDetailedState());        if (wifiNetworkInfo.getDetailedState() == NetworkInfo.DetailedState.OBTAINING_IPADDR                || wifiNetworkInfo.getDetailedState() == NetworkInfo.DetailedState.CONNECTING) {            return WIFI_CONNECTING;        } else if (wifiNetworkInfo.getDetailedState() == NetworkInfo.DetailedState.CONNECTED) {            return WIFI_CONNECTED;        } else {            Log.d(TAG, "getDetailedState() == " + wifiNetworkInfo.getDetailedState());            return WIFI_CONNECT_FAILED;        }    }

至此大功告成，文章如有错误欢迎各位指点
