我找到了答案：实现了 onDraw...

override fun onDraw(canvas: Canvas) {
    // super.onDraw(canvas) // commented not to draw default keyboard
    if (!isInEditMode) {
        onBufferDraw()
        if (mBuffer != null)
            canvas.drawBitmap(mBuffer!!, 0f, 0f, null)
    }
}

private fun onBufferDraw() {
    if (mBuffer == null) {
        mBuffer = Bitmap.createBitmap(width, height, Bitmap.Config.ARGB_8888)
        mCanvas = Canvas(mBuffer!!)
        invalidateAllKeys()
    }
// the rest of the draw function ...
