How to change the key label size of a custom keyboard in android

问题

I want to change the size of the keyboard label in my custom keyboard. The code I am using is like this,

 <Keyboard
     android:keyWidth="%10p"
     android:keyHeight="50px"
     android:horizontalGap="2px"
     android:verticalGap="2px" >
 <Row android:keyWidth="32px" >
     <Key android:keyLabel="A" />
     ...
 </Row>
 ...

So the issue is, if we take the code above the letter 'A'(label) is too small in my keyboard.

In KeyBoard class I can't find any xml attribute to change the visible size of the key label.

How to change the size of the key label?

Thanks.

Size of the text for character keys. android:keyTextSize can help.

Set this in your layout xml file, like this:

<android.inputmethodservice.KeyboardView
    android:id="@+id/keyboard_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:keyBackground="@drawable/key_background"
    android:keyTextColor="@android:color/white"
    android:keyTextSize="20sp"/>
