Answer 1

public int getWifiState ()
Returns
One of WIFI_STATE_DISABLED, WIFI_STATE_DISABLING, WIFI_STATE_ENABLED, WIFI_STATE_ENABLING, WIFI_STATE_UNKNOWNpublic boolean isWifiEnabled ()
Returns
true if Wi-Fi is enabled

Answer 2

你没看懂我的意思  我是希望在wifi状态改变时  能触发某个操作

Answer 3

接收下面这些intent
 183         mFilter = new IntentFilter();
 184         mFilter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
 185         mFilter.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);
 186         mFilter.addAction(WifiManager.NETWORK_IDS_CHANGED_ACTION);
 187         mFilter.addAction(WifiManager.SUPPLICANT_STATE_CHANGED_ACTION);
 188         mFilter.addAction(WifiManager.CONFIGURED_NETWORKS_CHANGED_ACTION);
 189         mFilter.addAction(WifiManager.LINK_CONFIGURATION_CHANGED_ACTION);
 190         mFilter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
 191         mFilter.addAction(WifiManager.RSSI_CHANGED_ACTION);

Answer 4

 private final BroadcastReceiver mReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            String action = intent.getAction();
            if (WifiManager.WIFI_STATE_CHANGED_ACTION.equals(action)) {
                handleWifiStateChanged(intent.getIntExtra(
                        WifiManager.EXTRA_WIFI_STATE, WifiManager.WIFI_STATE_UNKNOWN));
            } else if (WifiManager.SUPPLICANT_STATE_CHANGED_ACTION.equals(action)) {
                if (!mConnected.get()) {
                    handleStateChanged(WifiInfo.getDetailedStateOf((SupplicantState)
                            intent.getParcelableExtra(WifiManager.EXTRA_NEW_STATE)));
                }
            } else if (WifiManager.NETWORK_STATE_CHANGED_ACTION.equals(action)) {
                NetworkInfo info = (NetworkInfo) intent.getParcelableExtra(
                        WifiManager.EXTRA_NETWORK_INFO);
                mConnected.set(info.isConnected());
                handleStateChanged(info.getDetailedState());
            }
        }
    };按楼上方法就行了，可以参考wifienable.java
