如何防止自動連接到WiFi

Question

從通知欄打開WiFi適配器后，我嘗試阻止自動連接到WiFi並顯示對話框。

我以編程方式注冊了接收WIFI_STATE_CHANGED_ACTION的BroadcastReceiver。 在WIFI_STATE_ENABLED中，我從配置的網絡列表中刪除網絡。 但這行不通。

我在以下位置注冊BroadcastReceiver：

@Override
protected void onStart() {
    super.onStart();

    registerReceiver(wifiStatusReceiver, new IntentFilter(WifiManager.WIFI_STATE_CHANGED_ACTION));
}

並注銷onStop方法。

BroadcastReceiver代碼：

public class WiFiStatusReceiver extends BroadcastReceiver {

private WifiManager wifiManager;

@Override
public void onReceive(Context context, Intent intent) {

    wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE);

    if(!isInitialStickyBroadcast()) { //it is not a sticky intent

        switch(wifiManager.getWifiState()) {

            case WifiManager.WIFI_STATE_ENABLING:
                    Toast.makeText(context, R.string.enabling_wifi, Toast.LENGTH_SHORT).show();
                break;

            case WifiManager.WIFI_STATE_ENABLED:
                    Toast.makeText(context, R.string.enabled_wifi, Toast.LENGTH_SHORT).show();

                    wifiManager.disconnect();

                    if(!wifiManager.getConfiguredNetworks().isEmpty()) { //there are some networks

                        for(WifiConfiguration wifiConfig :wifiManager.getConfiguredNetworks()) {
                            wifiManager.removeNetwork(wifiConfig.networkId); 
                        }
                    }

                break;

            case WifiManager.WIFI_STATE_DISABLING:
                    Toast.makeText(context, R.string.disabling_wifi, Toast.LENGTH_SHORT).show();


                break;

            case WifiManager.WIFI_STATE_DISABLED:
                    Toast.makeText(context, R.string.disabled_wifi, Toast.LENGTH_SHORT).show();


                break;
        }
    } else { //is a sticky intent

        wifiManager.disconnect();

        if(!wifiManager.getConfiguredNetworks().isEmpty()) { //there are some networks

            for(WifiConfiguration wifiConfig :wifiManager.getConfiguredNetworks()) {
                wifiManager.removeNetwork(wifiConfig.networkId); 
            }
        }
    }
}

}

有什么建議么 ？

嘗試此操作以禁用Wifi .............，並在需要時啟用它 .........

boolean isOn = false;
WifiManager wifiManager = (WifiManager)this.context.getSystemService(Context.WIFI_SERVICE);
wifiManager.setWifiEnabled(isOn);
