我喜欢获取试图连接我的hoptspot的设备的SSID和IP地址。有什么方法可以检查他们并给予许可吗？

是其可能要注册您广播接收机活动的内部这样

BroadcastReceiver receiver = new BroadcastReceiver() { 
@Override 
public void onReceive(Context c, Intent intent) { 


@Override 
    public void onReceive(Context c, Intent intent) { 
    List<ScanResult> results = wifiDemo.wifi.getScanResults(); 
    ScanResult bestSignal = null; 
final String action = intent.getAction(); 
    if (action.equals(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION)) { 
    System.out.println("booladsssssssssssssssssssssssssssssss"); 
    } 
    for (ScanResult result : results) { 
     if (bestSignal == null 
      || WifiManager.compareSignalLevel(bestSignal.level, result.level) < 0) 
     bestSignal = result; 
    } 

    String message = String.format("%s networks found. %s is the strongest.", 
     results.size(), bestSignal.SSID); 
    Toast.makeText(wifiDemo, message, Toast.LENGTH_LONG).show(); 

    Log.d(TAG, "onReceive() message: " + message); 
    } 

，你应该把所有的权限，以您的清单文件..

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission> 
    <uses-permission android:name="android.permission.CHANGE_WIFI_STATE"></uses-permission> 
<uses-permission android:name="android.permission.UPDATE_DEVICE_STATS"></uses-permission> 
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"> </uses-permission> 
<uses-permission android:name="android.permission.WAKE_LOCK"></uses-permission> 

其完美的工作了我。如果你有任何疑问请发表评论..谢谢
