I got the solution for above question.

I have implement my custom keyboard (view with numbers) to input the numbers only in EditText.

I have used below function set for every edittext I used in screen.

fun disableSoftInputFromAppearing(editText: CustomEditText) {

    if (Build.VERSION.SDK_INT >= 26) {

        editText.setRawInputType(InputType.TYPE_NULL)
        editText.inputType = InputType.TYPE_CLASS_NUMBER
        editText.showSoftInputOnFocus = false
        editText.setOnClickListener {
            hideKeyboard()
        }

        try {               
            val f = TextView::class.java.getDeclaredField("mCursorDrawableRes")
            f.isAccessible = true
            f.set(editText, R.drawable.cursor)
        } catch (ignored: Exception) {
        }

    } else if (Build.VERSION.SDK_INT >= 24) {
        editText.inputType = InputType.TYPE_CLASS_NUMBER
        editText.showSoftInputOnFocus = false
        editText.setOnClickListener {
            hideKeyboard()
        }
        editText.setRawInputType(InputType.TYPE_CLASS_NUMBER)
        editText.setTextIsSelectable(true)
    } else {
        if (Build.VERSION.SDK_INT >= 21 ) {
            editText.showSoftInputOnFocus = false
        } else if (Build.VERSION.SDK_INT >= 11) {
            editText.setRawInputType(InputType.TYPE_CLASS_TEXT)
            editText.isCursorVisible = true
            editText.setTextIsSelectable(true)
        } else {
            editText.setRawInputType(InputType.TYPE_NULL)
            editText.isFocusable = true
        }

        try {
            val f = TextView::class.java.getDeclaredField("mCursorDrawableRes")
            f.isAccessible = true
            f.set(editText, R.drawable.cursor)
        } catch (ignored: Exception) {
            ignored.printStackTrace()
        }
    }
}

EditText in layout file

<EditText
    android:layout_width="@dimen/_25sdp"
    android:layout_height="@dimen/_25sdp"
    android:cursorVisible="true"
    android:digits="0123456789"
    android:gravity="center"
    android:imeOptions="actionNext"
    android:longClickable="false"
    android:maxLength="1"
    android:singleLine="true"
    android:textColor="#000000"
    android:textSize="@dimen/_16sdp"
    tools:text="0" />
