判斷Wifi是否連線成功，很簡單（需要用到廣播），

傳送一個廣播，filter.addAction("android.net.conn.CONNECTIVITY_CHANGE");

接收廣播

if(intent.getAction().equals("android.net.conn.CONNECTIVITY_CHANGE")){
                WifiSupport.getList(getContext(), list , -1);;//獲取資料
                adapter.notifyDataSetChanged();
                if(WifiSupport.isWifiContected
 
(getContext()) == 1){
                    Toast.makeText(getContext(), "連線成功"  + netConnectingid, Toast.LENGTH_SHORT).show();
                }else if(WifiSupport.isWifiContected(getContext()) == 2){
                    Toast.makeText(getContext(), "正在連線中"  + netConnectingid, Toast.LENGTH_SHORT).show
 
();
                }else{
                    Toast.makeText(getContext(), "網路變化了3", Toast.LENGTH_SHORT).show();
                }
            }

下面是判斷是否連線

public static final int WIFI_CONNECTED = 0x01;
    public static final int WIFI_CONNECT_FAILED = 0x02;
    public static final int WIFI_CONNECTING = 0x03
 
;
    /**
     * 判斷wifi是否連線成功,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，文章如有錯誤 歡迎各位指點
