检索无线网络连接状态（安卓） [英] Retrieve wifi connection status(Android)
本文介绍了检索无线网络连接状态（安卓）的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我按照<一href="http://stackoverflow.com/questions/4374862/how-to-programatically-create-and-read-wep-eap-wifi-configurations-in-android/4374934#4374934">following链接与本地的无线网络连接。这是工作完美。我能够连接到我本地的无线网络。
不过，我真正想要的无线网络的当前状态，我使用下面的code以获得无线的状态。但不幸的是，我只能得到禁用，已启用和扫描的状态，我真的想收到其他中间状态。
你能告诉我什么，我做错了。

IntentFilter的过滤器=新的IntentFilter（
ConnectivityManager.CONNECTIVITY_ACTION）;
registerReceiver（networkStateReceiver，过滤器）;
解决方案
注册reciver为::
mIntentFilter =新的IntentFilter（）;
mIntentFilter.addAction（WifiManager.SCAN_RESULTS_AVAILABLE_ACTION）;
mIntentFilter.addAction（WifiManager.NETWORK_STATE_CHANGED_ACTION）;
mIntentFilter.addAction（WifiManager.WIFI_STATE_CHANGED_ACTION）;

registerReceiver（mReceiver，mIntentFilter）;
公共无效的onReceive（上下文的背景下，意图意图）
{
串动= intent.getAction（）;
如果（action.equals（WifiManager.SCAN_RESULTS_AVAILABLE_ACTION））
{
}否则，如果（action.equals（WifiManager.WIFI_STATE_CHANGED_ACTION））
{
INT ITEMP = intent.getIntExtra（WifiManager.EXTRA_WIFI_STATE，
WifiManager.WIFI_STATE_UNKNOWN）;
LogUtil.d（LOG_SET，+++++++ ----------- ------ wifiStateReceiver +++++++，DEBUG）;
的CheckState（ITEMP）;
}否则，如果（action.equals（WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION））
{
DetailedState状态= WifiInfo.getDetailedStateOf（（SupplicantState）
intent.getParcelableExtra（WifiManager.EXTRA_SUPPLICANT_CONNECTED））;
改变状态（状态）;
LogUtil.d（LOG_SET，------------＆GT;＆GT;＆GT;＆GT; SUPPLICANT_STATE_CHANGED_ACTION＆LT;＆LT;＆LT;＆LT;＆LT;＆LT; -------，DEBUG） ;
}
否则，如果（action.equals（WifiManager.NETWORK_STATE_CHANGED_ACTION））
{
DetailedState状态=
（（的NetworkInfo）intent.getParcelableExtra（WifiManager.EXTRA_NETWORK_INFO））getDetailedState（）;
改变状态（状态）;
}
}
私人无效改变状态（DetailedState aState）
{
LogUtil.d（LOG_SET， ">>>>>>>>>>>>>>>>>>changeState<<<<<<<<<<<<<<<<"+aState, DEBUG）;
如果（aState == DetailedState.SCANNING）
{
Log.d（wifiSupplicanState，扫描）;
}
否则，如果（aState == DetailedState.CONNECTING）
{
Log.d（wifiSupplicanState，连接）;
}否则，如果（aState == DetailedState.OBTAINING_IPADDR）
{
Log.d（wifiSupplicanState，OBTAINING_IPADDR）;
}
否则，如果（aState == DetailedState.CONNECTED）
{

}
否则，如果（aState == DetailedState.DISCONNECTING）
{

I have followed the following link to connect with local wifi. It is working perfect. I am able to connect to my local wifi.
But, I really want the current status of the wifi, I am using following code to get the status of wifi. But unfortunately I am only able to get 'DISABLED', 'ENABLED' and 'SCANNING' status, I really want to receive other intermediary states.
Can you tell me what I am doing wrong.
public class ConnectionChangeReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
NetworkInfo info = intent.getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO);
Message msg = new Message();
msg.what = 5;
Bundle b = new Bundle();
String sStatus = "UnKnown";
switch(info.getDetailedState()){
case AUTHENTICATING:
sStatus = "Authenticating...";
break;
case CONNECTED:
sStatus = "Connected";
break;
case CONNECTING:
sStatus = "Connecting...";
break;
case DISCONNECTED:
sStatus = "Disconnected";
break;
case DISCONNECTING:
sStatus = "Disconnecting...";
break;
case FAILED:
sStatus = "Failed";
break;
case IDLE:
sStatus = "Idle";
break;
case OBTAINING_IPADDR :
sStatus = "Obtaining IP Address...";
break;
case SCANNING:
sStatus = "Scanning...";
break;
case SUSPENDED:
sStatus = "Suspended";
break;
}
b.putString("status", sStatus);
msg.setData(b);
mHandler.sendMessage(msg);
}
}
I register the broadcast receiver in the following way
IntentFilter filter = new IntentFilter(
ConnectivityManager.CONNECTIVITY_ACTION);
registerReceiver(networkStateReceiver, filter);
解决方案
register a reciver for::
mIntentFilter = new IntentFilter();
mIntentFilter.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);
mIntentFilter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
mIntentFilter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
mIntentFilter.addAction(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION);
registerReceiver(mReceiver, mIntentFilter);
public void onReceive(Context context, Intent intent)
{
String action = intent.getAction();
if(action.equals(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION))
{
}else if(action.equals(WifiManager.WIFI_STATE_CHANGED_ACTION))
{
int iTemp = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE,
WifiManager.WIFI_STATE_UNKNOWN);
LogUtil.d(LOG_SET, "+++++++-----------wifiStateReceiver------+++++++", DEBUG);
checkState(iTemp);
}else if(action.equals(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION))
{
DetailedState state =WifiInfo.getDetailedStateOf((SupplicantState)
intent.getParcelableExtra(WifiManager.EXTRA_SUPPLICANT_CONNECTED));
changeState(state);
LogUtil.d(LOG_SET, "------------>>>>SUPPLICANT_STATE_CHANGED_ACTION<<<<<<-------", DEBUG);
}
else if(action.equals(WifiManager.NETWORK_STATE_CHANGED_ACTION))
{
DetailedState state=
((NetworkInfo)intent.getParcelableExtra(WifiManager.EXTRA_NETWORK_INFO)).getDetailedState();
changeState(state);
}
}
private void changeState(DetailedState aState)
{
LogUtil.d(LOG_SET, ">>>>>>>>>>>>>>>>>>changeState<<<<<<<<<<<<<<<<"+aState, DEBUG);
if (aState == DetailedState.SCANNING)
{
Log.d("wifiSupplicanState", "SCANNING");
}
else if (aState == DetailedState.CONNECTING)
{
Log.d("wifiSupplicanState", "CONNECTING");
}else if(aState == DetailedState.OBTAINING_IPADDR)
{
Log.d("wifiSupplicanState", "OBTAINING_IPADDR");
}
else if (aState == DetailedState.CONNECTED)
{
Log.d("wifiSupplicanState", "CONNECTED");
}
else if (aState == DetailedState.DISCONNECTING)
{
Log.d("wifiSupplicanState", "DISCONNECTING");
}
else if (aState == DetailedState.DISCONNECTED)
{
Log.d("wifiSupplicanState", "DISCONNECTTED");
}
else if (aState == DetailedState.FAILED)
{
}
}
public void checkState(int aInt)
{
LogUtil.d(LOG_SET,"==>>>>>>>>checkState<<<<<<<<"+aInt, DEBUG);
if (aInt == WifiManager.WIFI_STATE_ENABLING)
{
Log.d("WifiManager", "WIFI_STATE_ENABLING");
}
else if (aInt== WifiManager.WIFI_STATE_ENABLED)
{
Log.d("WifiManager", "WIFI_STATE_ENABLED");
}
else if (aInt == WifiManager.WIFI_STATE_DISABLING)
{
Log.d("WifiManager", "WIFI_STATE_DISABLING");
}
else if (aInt == WifiManager.WIFI_STATE_DISABLED)
{
Log.d("WifiManager", "WIFI_STATE_DISABLED");
}
}
