我通过以下代码打开便携式 wifi 热点：

 private void createWifiAccessPoint() {
    WifiManager wifiManager = (WifiManager)getBaseContext().getSystemService(Context.WIFI_SERVICE);
    if(wifiManager.isWifiEnabled())
    {
        wifiManager.setWifiEnabled(false);          
    }       
    Method[] wmMethods = wifiManager.getClass().getDeclaredMethods();   //Get all declared methods in WifiManager class     
    boolean methodFound=false;
    for(Method method: wmMethods){
        if(method.getName().equals("setWifiApEnabled")){
            methodFound=true;
            WifiConfiguration netConfig = new WifiConfiguration();
            netConfig.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
            netConfig.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
            netConfig.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
            netConfig.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
            netConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
            netConfig.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
            netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
            netConfig.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
            try {
                boolean apstatus=(Boolean) method.invoke(wifiManager, netConfig,true);          
                //statusView.setText("Creating a Wi-Fi Network \""+netConfig.SSID+"\"");
                for (Method isWifiApEnabledmethod: wmMethods)
                {
                    if(isWifiApEnabledmethod.getName().equals("isWifiApEnabled")){
                        while(!(Boolean)isWifiApEnabledmethod.invoke(wifiManager)){
                        };
                        for(Method method1: wmMethods){
                            if(method1.getName().equals("getWifiApState")){
                                int apstate;
                                apstate=(Integer)method1.invoke(wifiManager);
                                //                    netConfig=(WifiConfiguration)method1.invoke(wifi);
                                //statusView.append("\nSSID:"+netConfig.SSID+"\nPassword:"+netConfig.preSharedKey+"\n");
                            }
                        }
                    }
                }
                if(apstatus)
                {
                    System.out.println("SUCCESSdddd");  
                    //statusView.append("\nAccess Point Created!");
                    //finish();
                    //Intent searchSensorsIntent = new Intent(this,SearchSensors.class);            
                    //startActivity(searchSensorsIntent);
                }else
                {
                    System.out.println("FAILED");   
                    //statusView.append("\nAccess Point Creation failed!");
                }
            } catch (IllegalArgumentException e) {
                e.printStackTrace();
            } catch (IllegalAccessException e) {
                e.printStackTrace();
            } catch (InvocationTargetException e) {
                e.printStackTrace();
            }
        }      
    }
    if(!methodFound){
        //statusView.setText("Your phone's API does not contain setWifiApEnabled method to configure an access point");
    }
}

它对我有用.......热点打开......但也有通过单击“菜单”按钮进行高级设置......这是一个问题...... DHCP在LanSettings和电源模式仅工作 5 分钟....我希望启用 DHCP 并且 PowerMode -“始终开启”...我该如何解决？

您可能需要查看 Android 源代码才能找到答案。使用您的代码是能够连接并获取 IP 地址的设备吗？如果是这种情况，则 AP 的 DHCP 工作正常。

就我个人而言，我什至没有启用或禁用 DHCP 选项或 ICS 上的 PowerMode。
