Android 如何更改hackerskeyboard项目的字体大小？

我安装了项目，并将以下行添加到文件中 kbd_full.xml

  <Row  >
            <Key
                android:horizontalGap="1.1%p"
                android:keyLabel="GMAIL"
                android:keyOutputText="GMAIL"
                android:keyWidth="10.0%p" />
            <Key
                android:horizontalGap="1.1%p"
                android:keyLabel="Hotmail"
                android:keyOutputText="Hotmail"
                android:keyWidth="19.0%p" />
            <Key
                android:horizontalGap="1.1%p"
                android:keyLabel="YAHOO"
                android:keyOutputText="YAHOO"

                android:keyWidth="19.0%p" />
            <Key
                android:horizontalGap="1.1%p"
                android:keyLabel="LIVE"
                android:keyOutputText="LIVE"
                android:keyWidth="13.185714%p" />
            <Key
                android:horizontalGap="1.1%p"
                android:keyLabel="MAIL"
                android:keyOutputText="MAIL"
                android:keyWidth="13.185714%p" />
            <Key
                android:horizontalGap="1.1%p"
                android:keyLabel="\@"
                android:keyOutputText="\@"
                android:keyWidth="12.185714%p" />
            <Key
                android:horizontalGap="1.1%p"
                android:keyLabel=".COM"
                android:keyOutputText=".COM"
                android:keyWidth="13.185714%p" />
            <Key
                android:horizontalGap="1.1%p"
                android:keyLabel=".CO.UK"
                android:keyOutputText=".CO.UK"
                android:keyWidth="17.0%p" />
            <Key
                android:horizontalGap="1.1%p"
                android:keyLabel=".EU"
                android:keyOutputText=".EU"
                android:keyWidth="13.185714%p" />
            <Key
                android:horizontalGap="1.1%p"
                android:keyLabel="-"
                android:keyOutputText="-"
                android:keyWidth="13.185714%p" />
            <Key
                android:horizontalGap="1.1%p"
                android:keyLabel="_"
                android:keyOutputText="_"
                android:keyWidth="13.185714%p" />
        </Row>

但是它看起来太大了，所以我想减小这一行的字体大小，我试图更改属性android:labelTextSize=“6dp”，但没有发生任何事情，我如何在这个项目中减小字体大小

我用以下方法来解决我的问题

 <Row  android:rowEdgeFlags="top"   android:keyHeight="4%p"     android:horizontalGap="1.8%p">
        <Key
             android:codes="300"

            android:keyIcon="@drawable/icon_gmail"
            android:keyOutputText="gmail"
             />
        <Key
            android:codes="301"

             android:keyOutputText="hotmail"
            android:keyIcon="@drawable/icon_hotmail" />
        <Key
             android:codes="302"

            android:keyOutputText="yahoo"
           android:keyIcon="@drawable/icon_yahoo"

            />


      <Key
           android:codes="303"

            android:keyIcon="@drawable/icon_live"
            android:keyOutputText="live"
            />
        <Key
               android:codes="304"

             android:keyIcon="@drawable/icon_mail"
            android:keyOutputText="mail"
           />
        <Key
               android:codes="305"

              android:keyIcon="@drawable/icon_at"
            android:keyOutputText="\@"
           />
        <Key
               android:codes="306"

             android:keyIcon="@drawable/icon_com"
            android:keyOutputText=".com"
            />
        <Key
               android:codes="307"

            android:keyIcon="@drawable/icon_co_uk"
            android:keyOutputText=".co.uk"
            />
        <Key
               android:codes="308"

           android:keyIcon="@drawable/icon_eu"
            android:keyOutputText=".eu"
            />
        <Key
               android:codes="309"

             android:keyIcon="@drawable/icon_dash"
            android:keyOutputText="-"
           />
        <Key
               android:codes="310"

            android:keyIcon="@drawable/icon_underscore"
            android:keyOutputText="_"
            />
     </Row>
