KeyboardView

Since KeyboardView was deprecated in API level 29. Google recommends to copy the file to your project. This library just do the thing for you. For more information, please refer:

https://developer.android.com/reference/android/inputmethodservice/KeyboardView

Reminder

This library remove accessibility support, if you need that, you may find other solution.

Usage

You should replace KeyboardView attributes of "android" namespace to the third party namespace "app".

Replace the deprecated KeyboardView:

 <android.inputmethodservice.KeyboardView
        android:id="@+id/keyboardview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/background_gray"
        android:keyBackground="@drawable/key_bg"
        android:keyTextColor="@color/app_text_color"
        android:shadowColor="@android:color/transparent" />

To the custom one:

 <com.hijamoya.keyboardview.KeyboardView
        android:id="@+id/keyboardview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@color/background_gray"
        app:keyBackground="@drawable/key_bg"
        app:keyTextColor="@color/app_text_color"
        app:shadowColor="@android:color/transparent"  />

Also change namespace of your keyboard xml layout:

<Keyboard xmlns:android="http://schemas.android.com/apk/res/android"
    android:keyWidth="12.5%p"
    android:keyHeight="8%p">
    <Row>
        <Key
            android:codes="49"
            android:keyEdgeFlags="left"
            android:keyLabel="1" />
        <Key
            android:codes="50"
            android:keyLabel="2" />
    </Row>
</Keyboard>

To

<Keyboard xmlns:app="http://schemas.android.com/apk/res-auto"
    app:keyWidth="12.5%p"
    app:keyHeight="8%p">
    <Row>
        <Key
            app:codes="49"
            app:keyEdgeFlags="left"
            app:keyLabel="1" />
        <Key
            app:codes="50"
            app:keyLabel="2" />
    </Row>
</Keyboard>

Since we don't provide the default theme in android framework, you should define a custom theme by yourself:

  <style name="Widget.KeyboardView" parent="android:Widget">
        <item name="android:background">@android:drawable/keyboard_background</item>
        <item name="android:keyBackground">@android:drawable/btn_keyboard_key</item>
        <item name="android:keyTextSize">22sp</item>
        <item name="android:keyTextColor">#FFFFFFFF</item>
        <item name="android:keyPreviewLayout">@android:layout/keyboard_key_preview</item>
        <item name="android:keyPreviewOffset">-12dip</item>
        <item name="android:keyPreviewHeight">80dip</item>
        <item name="android:labelTextSize">14sp</item>
        <item name="android:popupLayout">@android:layout/keyboard_popup_keyboard</item>
        <item name="android:verticalCorrection">-10dip</item>
        <item name="android:shadowColor">#BB000000</item>
        <item name="android:shadowRadius">2.75</item>
  </style>

To

    <style name="KeyboardView" parent="android:Widget">
        <item name="android:background">@color/background_gray</item>
        <item name="keyBackground">@drawable/key_bg</item>
        <item name="keyTextSize">22sp</item>
        <item name="keyTextColor">@color/app_text_color</item>
        <item name="keyPreviewLayout">@android:layout/keyboard_key_preview</item>
        <item name="keyPreviewOffset">-12dp</item>
        <item name="keyPreviewHeight">80dp</item>
        <item name="labelTextSize">14sp</item>
        <item name="popupLayout">@android:layout/keyboard_popup_keyboard</item>
        <item name="verticalCorrection">-10dp</item>
        <item name="shadowColor">@android:color/transparent</item>
        <item name="shadowRadius">2.75</item>
    </style>
