Android的符號代碼

Question

我正在用xamarin androd手動鍵盤開發應用程序。我手動鍵盤由按鍵從0-9和一些特殊字符說 - ，$，＃，@ ..通過搜索形式我得到的是如下所述的NUMERICS。我的代碼鍵代碼..

<Keyboard xmlns:android="http://schemas.android.com/apk/res/android" 
android:keyWidth="10%p" android:horizontalGap="0px" 
android:verticalGap="0px" android:keyHeight="60dip"> 

<Row> 
<Key android:codes="8" android:keyLabel="1" android:keyEdgeFlags="left" /> 
<Key android:codes="9" android:keyLabel="2"/> 
<Key android:codes="10" android:keyLabel="3"/> 
<Key android:codes="11" android:keyLabel="4"/> 
<Key android:codes="12" android:keyLabel="5"/> 
<Key android:codes="13" android:keyLabel="6"/> 
<Key android:codes="14" android:keyLabel="7"/> 
<Key android:codes="15" android:keyLabel="8"/> 
<Key android:codes="16" android:keyLabel="9"/> 
<Key android:codes="7" android:keyLabel="0" android:keyEdgeFlags="right" /> 
</Row> 

<Row android:rowEdgeFlags="bottom"> 
<Key android:codes="56" android:keyIcon="@drawable/sym_keyboard_done" android:keyWidth="15%p" android:keyEdgeFlags="left" android:horizontalGap="10%p"/> 
<Key android:codes="40" android:keyLabel="l"/> 
<Key android:codes="44" android:keyLabel="p"/> 
<Key android:codes="47" android:keyLabel="s"/> 
<Key android:codes="109" android:keyLabel="-"/> 
<Key android:codes="109" android:keyLabel="@"/> 
<Key android:codes="67" android:keyIcon="@drawable/sym_keyboard_delete" android:keyWidth="15%p" android:keyEdgeFlags="right" android:isRepeatable="true"/> 
<Key android:codes="66" android:keyIcon="@drawable/sym_keyboard_return" android:keyWidth="15%p" android:keyEdgeFlags="right"/> 
</Row> 

我想知道主要是特殊字符 - ，@的android：code值。所以，你可以幫助我的代碼值。提前感謝你。
