Android.Hardware.Input.InputManager.ActionQueryKeyboardLayouts Field
Broadcast Action: Query available keyboard layouts.

Syntax

[Android.Runtime.Register("ACTION_QUERY_KEYBOARD_LAYOUTS")]
public const string ActionQueryKeyboardLayouts

Remarks

Broadcast Action: Query available keyboard layouts.

The input manager service locates available keyboard layouts by querying broadcast receivers that are registered for this action. An application can offer additional keyboard layouts to the user by declaring a suitable broadcast receiver in its manifest.

Here is an example broadcast receiver declaration that an application might include in its AndroidManifest.xml to advertise keyboard layouts. The meta-data specifies a resource that contains a description of each keyboard layout that is provided by the application.

xml Example

 <receiver android:name=".InputDeviceReceiver"
         android:label="@string/keyboard_layouts_label">
     <intent-filter>
         <action android:name="android.hardware.input.action.QUERY_KEYBOARD_LAYOUTS" />
     </intent-filter>
     <meta-data android:name="android.hardware.input.metadata.KEYBOARD_LAYOUTS"
             android:resource="@xml/keyboard_layouts" />
 </receiver>
 

In the above example, the @xml/keyboard_layouts resource refers to an XML resource whose root element is <keyboard-layouts> that contains zero or more <keyboard-layout> elements. Each <keyboard-layout> element specifies the name, label, and location of a key character map for a particular keyboard layout. The label on the receiver is used to name the collection of keyboard layouts provided by this receiver in the keyboard layout settings.

xml Example

 <?xml version="1.0" encoding="utf-8"?>
 <keyboard-layouts xmlns:android="http://schemas.android.com/apk/res/android">
     <keyboard-layout android:name="keyboard_layout_english_us"
             android:label="@string/keyboard_layout_english_us_label"
             android:keyboardLayout="@raw/keyboard_layout_english_us" />
 </keyboard-layouts>
 
 The android:name attribute specifies an identifier by which
 the keyboard layout will be known in the package.
 The android:label attributes specifies a human-readable descriptive
 label to describe the keyboard layout in the user interface, such as "English (US)".
 The android:keyboardLayout attribute refers to a
 
 key character map resource that defines the keyboard layout.
