Keyboard

public class Keyboard
extends Object

This class was deprecated in API level 29.
This class is deprecated because this is just a convenient UI widget class that application developers can re-implement on top of existing public APIs. If you have already depended on this class, consider copying the implementation from AOSP into your project or re-implementing a similar widget by yourselves

Loads an XML description of a keyboard and stores the attributes of the keys. A keyboard consists of rows of keys.

The layout file for a keyboard contains XML that looks like the following snippet:

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

Summary

XML attributes

android:horizontalGap

Default horizontal gap between keys.

May be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters).

May be a fractional value, which is a floating point number appended with either % or %p, such as "14.5%". The % suffix always means a percentage of the base size; the optional %p suffix provides a size relative to some parent container.

android:keyHeight

Default height of a key, in pixels or percentage of display width.

May be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters).

May be a fractional value, which is a floating point number appended with either % or %p, such as "14.5%". The % suffix always means a percentage of the base size; the optional %p suffix provides a size relative to some parent container.

android:keyWidth

Default width of a key, in pixels or percentage of display width.

May be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters).

May be a fractional value, which is a floating point number appended with either % or %p, such as "14.5%". The % suffix always means a percentage of the base size; the optional %p suffix provides a size relative to some parent container.

android:verticalGap

Default vertical gap between rows of keys.

May be a dimension value, which is a floating point number appended with a unit such as "14.5sp". Available units are: px (pixels), dp (density-independent pixels), sp (scaled pixels based on preferred font size), in (inches), and mm (millimeters).

May be a fractional value, which is a floating point number appended with either % or %p, such as "14.5%". The % suffix always means a percentage of the base size; the optional %p suffix provides a size relative to some parent container.
