鸿蒙应用app开发，如何屏蔽调Home键和返回键？

参考下面代码，能部分实现你的需求，返回键可以实现屏蔽，home键还不行

package com.huawei.keyeventdemo;

import com.huawei.keyeventdemo.slice.MainAbilitySlice;

import ohos.aafwk.ability.Ability;

import ohos.aafwk.content.Intent;

import ohos.multimodalinput.event.KeyEvent;

public class MainAbility extends Ability {

    @Override

    public void onStart(Intent intent) {

        super.onStart(intent);

        super.setMainRoute(MainAbilitySlice.class.getName());

    }

   @Override

    public boolean onKeyDown(int keyCode, KeyEvent keyEvent) {

        switch(keyCode) {

            case KeyEvent.KEY_HOME:return true;

            case KeyEvent.KEY_BACK:return true;

            case KeyEvent.KEY_CALL:return true;

            case KeyEvent.KEY_SYM: return true;

            case KeyEvent.KEY_VOLUME_DOWN: return true;

            case KeyEvent.KEY_VOLUME_UP: return true;

            case KeyEvent.KEY_STAR: return true;

        }

        return super.onKeyDown(keyCode, keyEvent);

    }

}

应该跟安卓差不了多少
