在 Android 自定义键盘中，如何将字母键盘更改为符号键盘？

Question

While Navigate User from Alphabets Keyboard to Symbols Keyboard, Layout Alignment gets spoiled. By Default, Layout takes 5dp padding & User can't see the Last Column Keys.

Note: Images shown in below.

I handled Key Actions to Navigate User from Alphabets Keyboard to Symbol Keyboard in the onKey Method

override fun onKey(primaryCode: Int, keyCodes: IntArray?) {
when (primaryCode) {
        KEYCODE_ALPHABETS -> {
            keyboardView?.keyboard = Keyboard(this, R.xml.keyboard)
        }

        KEYCODE_SYMBOLS_1 -> {
            keyboardView?.keyboard = Keyboard(this, R.xml.keyboard_symbols_1)
        }

        KEYCODE_SYMBOLS_2 -> {
            keyboardView?.keyboard = Keyboard(this, R.xml.keyboard_symbols_2)
        }
 }

}

Pls Suggest is there any other way to change keyboard (or) what I've done wrong

What I faced is shown below. Alphabets Keyboard:

While Change Keyboard in KeyboardView using setMethod in Kotlin, It changes with some mild UI Error

Symbols Keyboard:

Note:

• Symbols Keyboard has no issue. Bcz We tried to have it as a Primary Keyboard to inflate at very first time. It has no issue at that time.
• Issue is in Keyboard Change portion (onKey Method). Alphabets Keyboard also not fully compatible while changing Keyboard

Answer 1

Keyboard Layout draws every key based on the percentage not in dp . So declare your key width as %p not in dp

In Layout file

<Row
            android:horizontalGap="@fraction/key_horizontal_ten_keys_gap"
            android:keyWidth="@fraction/ten_keys_key_width"
            android:rowEdgeFlags="top">
</Row>

In Resource file

<fraction name="ten_keys_key_width">8.8%p</fraction>
