這篇文章主要介紹了Android獲取熱點(diǎn)主機(jī)ip和連接熱點(diǎn)手機(jī)ip的相關(guān)資料,需要的朋友可以參考下

其中定義WIFI AP的幾個(gè)狀態(tài)

public static final int WIFI_AP_STATE_DISABLING = 10;  
public static final int WIFI_AP_STATE_DISABLED = 11;  
public static final int WIFI_AP_STATE_ENABLING = 12;  
public static final int WIFI_AP_STATE_ENABLED = 13;  
public static final int WIFI_AP_STATE_FAILED = 14;

對(duì)應(yīng)于WifiMangaer.java中對(duì)這幾個(gè)狀態(tài)的定義。

獲取WIFI熱點(diǎn)的狀態(tài)：

public int getWifiApState(Context mContext) {  
  WifiManager wifiManager = (WifiManager) mContext.getSystemService(Context.WIFI_SERVICE);  
    try {  
      Method method = wifiManager.getClass().getMethod("getWifiApState");  
      int i = (Integer) method.invoke(wifiManager);  
      Log.i(TAG,"wifi state: " + i);  
      return i;  
    } catch (Exception e) {  
      Log.e(TAG,"Cannot get WiFi AP state" + e);  
      return WIFI_AP_STATE_FAILED;  
    }  
  }

判斷Wifi熱點(diǎn)是否可用：

private ArrayList<String> getConnectedHotIP() { 
  ArrayList<String> connectedIP = new ArrayList<String>(); 
  try { 
    BufferedReader br = new BufferedReader(new FileReader( 
        "/proc/net/arp")); 
    String line; 
    while ((line = br.readLine()) != null) { 
      String[] splitted = line.split(" +"); 
      if (splitted != null && splitted.length >= 4) { 
        String ip = splitted[0]; 
        connectedIP.add(ip); 
      } 
    } 
  } catch (Exception e) { 
    e.printStackTrace(); 
  } 
  return connectedIP; 
} 
//輸出鏈接到當(dāng)前設(shè)備的IP地址 
public void printHotIp() { 

  ArrayList<String> connectedIP = getConnectedHotIP(); 
  StringBuilder resultList = new StringBuilder(); 
  for (String ip : connectedIP) { 
    resultList.append(ip); 
    resultList.append("\n"); 
  } 
  System.out.print(resultList); 
  Log.d(TAG,"---->>heww resultList="+resultList); 
}

當(dāng)然在應(yīng)用中要添加訪問(wèn)WIFI設(shè)備的權(quán)限：

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

獲取熱點(diǎn)主機(jī)ip地址的代碼：

WifiManager wifiManager = (WifiManager) getSystemService(Context.WIFI_SERVICE);
      DhcpInfo info=wifiManager.getDhcpInfo();
      System.out.println(info.serverAddress);

總結(jié)

以上所述是小編給大家介紹的Android獲取熱點(diǎn)主機(jī)ip和連接熱點(diǎn)手機(jī)ip的方法 ，希望對(duì)大家有所幫助，如果大家有任何疑問(wèn)請(qǐng)給我留言，小編會(huì)及時(shí)回復(fù)大家的。在此也非常感謝大家對(duì)腳本之家網(wǎng)站的支持！
