android - 如何在自定义键盘上添加指数(上标)符号？

Question

我正在使用自定义键盘，但我一直坚持添加指数符号，我是否只需添加“^”？这是我的代码，抱歉我是菜鸟

<?xml version="1.0" encoding="utf-8"?>
    <Keyboard xmlns:android="http://schemas.android.com/apk/res/android"
        android:keyWidth="15%p"
        android:keyHeight="15%p" >
<Row>
            <Key android:codes="+"    android:keyLabel="a" android:horizontalGap="2%p"/>
            <Key android:codes="-"    android:keyLabel="b" android:horizontalGap="2%p"/>
            <Key android:codes="*"    android:keyLabel="c" android:horizontalGap="2%p" />
            <Key android:codes="/"    android:keyLabel="d" android:horizontalGap="2%p" />
            <Key android:codes="^"    android:keyLabel="^" android:horizontalGap="2%p" />
            <Key android:codes="("    android:keyLabel="(" android:horizontalGap="2%p"/>
            <Key android:codes=")"    android:keyLabel=")" android:horizontalGap="2%p"/>

        </Row>

        <Row>
            <Key android:codes="-1"    android:keyLabel="@drawable/backspace" android:keyWidth="34%p" android:horizontalGap="4%p"/>
            <Key android:codes="100"    android:keyLabel="Enter" android:keyWidth="53%p" android:horizontalGap="4%p"/>
        </Row>
    </Keyboard>
