HTC Android手机没法修改热点 Hotspot SSID名称和密码！【已解决】

Some htc phones seems to use a class of type HotspotProfile to 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--");    }
