In Android Custom Keyboard, how to change Alphabets Keyboard to Symbols Keyboard?

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

I am having the same issue, did you ever figure this out? – Macmullin

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>
