HTC Android Hotspot 热点配置 之DHCP（包括如何让其它手机连接上去）

最近在研究手机热点的建立。HTC手机比较坑爹，首先一个，是不能按常规的办法修改 SSID, BSSID,

在网上搜了下，有篇博客把这个问题解决了，请参考：/article/2575919.html

然后就发现HTC手机热点是建好了，但是其他手机去连它，怎么也连不上，后来发现，使用静态IP能解决这个问题，但太麻烦了。

研究了下通过手动配置HTC的WiFi热点程序 com.htc.WiFiRouter 里面有一个Local DHCP的配置,把它勾上就能自动获取IP。

但要怎么样用代码实现呢这下坑爹了。

研究了半天，还是只有把HTC独有的类给它全部dump出来，代码如下

[java] view
plaincopy

public void dumpHTCWifiFunction2(){

Log.e(TAG, "dumpHTCWifiFunction2++");

// Method[] classMethods = null;

Field localField1;



Field[] fieldlist;

WifiConfiguration apConfig = new WifiConfiguration();

try {

localField1 = WifiConfiguration.class.getDeclaredField("mWifiApProfile");

localField1.setAccessible(true);



Object localObject2 = localField1.get(apConfig);



localField1.setAccessible(false);



if(localObject2!=null){

fieldlist = localObject2.getClass().getDeclaredFields();



for (int i = 0;i < fieldlist.length; i++)



{



Log.e(TAG, "found api: "+ fieldlist[i].getName());



}

}





} catch (NoSuchFieldException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IllegalArgumentException e) {

// TODO Auto-generated catch block

e.printStackTrace();

} catch (IllegalAccessException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}



Log.e(TAG, "dumpHTCWifiFunction2--");

}

发现了 dhcpEnable 这个成员变量，刚开始猜它是boolean变量，但错了，在设置的时候会发生错误。

干脆把它的类型也打印出来吧，打印语句改为：

Log.e(TAG, "found api: "+ fieldlist[i].getName()+" type:"+fieldlist[i].toString());

found api: dhcpEnable type:public int android.net.wifi.WifiConfiguration$HotspotProfile.dhcpEnable

原来它是int型变量,估且猜它是1为enable. 设置之后，果然可以。

完整代码如下：

[java] view
plaincopy

private boolean setWifiSSIDForHTC(WifiConfiguration apConfig) {

boolean successed = true;



// WifiConfiguration mnetConfig = new WifiConfiguration();

Field localField1;



try {



localField1 = WifiConfiguration.class.getDeclaredField("mWifiApProfile");



localField1.setAccessible(true);



Object localObject2 = localField1.get(apConfig);



localField1.setAccessible(false);

if(localObject2!=null){



Field localField5 = localObject2.getClass().getDeclaredField("SSID");



localField5.setAccessible(true);



localField5.set(localObject2, apConfig.SSID);// netConfig.SSID);



localField5.setAccessible(false);



Field localField4 = localObject2.getClass().getDeclaredField("BSSID");



localField4.setAccessible(true);



localField4.set(localObject2, apConfig.BSSID);//netConfig.BSSID);



localField4.setAccessible(false);



Field localField6 = localObject2.getClass().getDeclaredField("dhcpEnable");



localField6.setAccessible(true);



// localField6.set(localObject2, "true");//netConfig.BSSID);

localField6.setInt(localObject2, 1);



localField6.setAccessible(false);



}



} catch(Exception e) {



e.printStackTrace();



}

return successed;

}
