Some htc phones seems to use a class of typeHotspotProfileto keep its configuration. So, before callingsetWifiApEnabled, you need set the ssid in htc's way:

boolean isHtc = false;

try {

isHtc = WifiConfiguration.class

.getDeclaredField("mWifiApProfile") != null;

} catch (java.lang.NoSuchFieldException e) {

isHtc = false;

}

WifiConfiguration apConfig = new WifiConfiguration();

apConfig.SSID = "H3c_xx";

apConfig.preSharedKey = "h3ch3ch3c";

apConfig.allowedKeyManagement

.set(WifiConfiguration.KeyMgmt.WPA_PSK);

if (isHtc) {

setHTCSSID(apConfig);

}

// 通过反射调用设置热点

Method method;

method = wifiManager.getClass().getMethod("setWifiApEnabled",

WifiConfiguration.class, Boolean.TYPE);

// 返回热点打开状态

boolean flag = (Boolean) method.invoke(wifiManager, apConfig, true);

设置SSID和密码

public void setHTCSSID(WifiConfiguration config) {

try {

Field mWifiApProfileField = WifiConfiguration.class

.getDeclaredField("mWifiApProfile");

mWifiApProfileField.setAccessible(true);

Object hotSpotProfile = mWifiApProfileField.get(config);

mWifiApProfileField.setAccessible(false);

if (hotSpotProfile != null) {

Field ssidField = hotSpotProfile.getClass().getDeclaredField(

"SSID");

ssidField.setAccessible(true);

ssidField.set(hotSpotProfile, config.SSID);

ssidField.setAccessible(false);

Field localField3 = hotSpotProfile.getClass().getDeclaredField(

"key");

localField3.setAccessible(true);

localField3.set(hotSpotProfile, config.preSharedKey);

localField3.setAccessible(false);

Field localField6 = hotSpotProfile.getClass().getDeclaredField(

"dhcpEnable");

localField6.setAccessible(true);

localField6.setInt(hotSpotProfile, 1);

localField6.setAccessible(false);

}

} catch (Exception e) {

e.printStackTrace();

}

}

可以通过遍历属性的方法查看还有那些可以修改的值：

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()

+ " type:" + fieldlist[i].toString());

}

}

} catch (NoSuchFieldException e) {

e.printStackTrace();

} catch (IllegalArgumentException e) {

e.printStackTrace();

} catch (IllegalAccessException e) {

e.printStackTrace();

}

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

}
