Adobe Air - 键盘事件错误

下面的代码抛出错误1046：未找到类型或不是编译时常量：KeyboardEvent。

有人知道为什么吗？

import flash.desktop.NativeApplication;
import flash.desktop.SystemIdleMode;
import flash.system.Capabilities;
import flash.system.System;

if (Capabilities.cpuArchitecture == "ARM")
{
NativeApplication.nativeApplication.addEventListener(KeyboardEvent.KEY_DOWN, handleKeys, false, 0, true);
}



function handleKeys(event:KeyboardEvent):void
{
    if (event.keyCode == Keyboard.BACK)
    {
        NativeApplication.nativeApplication.exit();
    }
}

原文

The code below throws the error 1046: Type was not found or was not a compile-time constant: KeyboardEvent.

Does anybody know why?

import flash.desktop.NativeApplication;
import flash.desktop.SystemIdleMode;
import flash.system.Capabilities;
import flash.system.System;

if (Capabilities.cpuArchitecture == "ARM")
{
NativeApplication.nativeApplication.addEventListener(KeyboardEvent.KEY_DOWN, handleKeys, false, 0, true);
}



function handleKeys(event:KeyboardEvent):void
{
    if (event.keyCode == Keyboard.BACK)
    {
        NativeApplication.nativeApplication.exit();
    }
}

您需要导入 KeyboardEvent 类。

这是否有效（请注意我添加的附加导入语句）：

import flash.desktop.NativeApplication;
import flash.desktop.SystemIdleMode;
import flash.system.Capabilities;
import flash.system.System;
import flash.events.KeyboardEvent;
import flash.ui.Keyboard;

if (Capabilities.cpuArchitecture == "ARM")
{
NativeApplication.nativeApplication.addEventListener(KeyboardEvent.KEY_DOWN, handleKeys, false, 0, true);
}



function handleKeys(event:KeyboardEvent):void
{
    if (event.keyCode == Keyboard.BACK)
    {
        NativeApplication.nativeApplication.exit();
    }
}

You need to import the KeyboardEvent class.

Does this work (Note the additional import statement I've added):

import flash.desktop.NativeApplication;
import flash.desktop.SystemIdleMode;
import flash.system.Capabilities;
import flash.system.System;
import flash.events.KeyboardEvent;
import flash.ui.Keyboard;

if (Capabilities.cpuArchitecture == "ARM")
{
NativeApplication.nativeApplication.addEventListener(KeyboardEvent.KEY_DOWN, handleKeys, false, 0, true);
}



function handleKeys(event:KeyboardEvent):void
{
    if (event.keyCode == Keyboard.BACK)
    {
        NativeApplication.nativeApplication.exit();
    }
}
