Android：wifiManager.isWifiEnabled（）返回TRUE，但WiFi被禁用

在這裏，Android 4.0平板電腦。Android：wifiManager.isWifiEnabled（）返回TRUE，但WiFi被禁用

wifiManager.isWifiEnabled()

回報true但如果我看的Android默認WLAN設置，無線網絡仍然是關...

我如何檢查無線網絡連接，而不使用isWifiEnabled()？

有什麼好笑的是，isWifiEnabled返回'getWifiState（）== WIFI_STATE_ENABLED;' – njzk2

如果您正在測試的WiFi改變其狀態之後，再isWifiEnabled（）的結果是錯誤的。我遇到了這個問題，試着暫停一下，然後測試一下，然後運行。說，5秒後。重點是傳播需要幾秒鐘的時間。 –

你可以嘗試使用getWifiState()
獲取Wi-Fi功能的狀態。
返回：
一個WIFI_STATE_DISABLED，WIFI_STATE_DISABLING，WIFI_STATE_ENABLED，WIFI_STATE_ENABLING，WIFI_STATE_UNKNOWN

ok，getWiFiState（）== WIFI_STATE_DISABLED並且WiFiEnabled（）返回true ... –

Intresting情況，我會嘗試去處理它。我寫信給你，如果我找到一些答案。 – Arseniy

好的，讓我知道。謝謝！ –

嘗試以下代碼。

SupplicantState supState; 
wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE); 
WifiInfo wifiInfo = wifiManager.getConnectionInfo(); 
supState = wifiInfo.getSupplicantState();

它將在你打電話getSupplicantState（）時返回這些狀態之一;

ASSOCIATED - Association completed. 

ASSOCIATING - Trying to associate with an access point. 

COMPLETED - All authentication completed. 

DISCONNECTED - This state indicates that client is not associated, but is likely to start looking for an access point. 

DORMANT - An Android-added state that is reported when a client issues an explicit DISCONNECT command. 

FOUR_WAY_HANDSHAKE - WPA 4-Way Key Handshake in progress. 

GROUP_HANDSHAKE - WPA Group Key Handshake in progress. 

INACTIVE - Inactive state. 

INVALID - A pseudo-state that should normally never be seen. SCANNING - Scanning for a network. 

UNINITIALIZED - No connection.

其實supState是UNINITIALIZED和isWifiEnabled（）= TRUE ...是否正確？ –

ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); 
    NetworkInfo netInfo = cm.getActiveNetworkInfo(); 
    State wifi = cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI).getState();

並檢查wifi.states ....

你還必須檢查是否有針對該許可您的AndroidManifest.xml

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

您可以使用Settings.Global.WIFI_ON

public boolean isWiFiSettingOn() { 
     boolean isOn = false; 
     try { 
      isOn = Settings.Global.getInt(mContentResolver, Settings.Global.WIFI_ON) != 0; 
     } catch (Settings.SettingNotFoundException e) { 
      e.printStackTrace(); 
      // This should never happen 
      Log.e(TAG, "Couldn't retrieve status of Settings.Global.WIFI_ON - returning the default value FALSE")`enter code here`; 
     } 

     Log.d(TAG, "isWiFiSettingOn? - " + isOn); 
     return isOn; 
    }
