How to set different background of keys for Android Custom Keyboard
Date : March 29 2020, 07:55 AM
Hope that helps As an example, there's a small downloadable project that creates a custom numeric keyboard. To the CustomKeyboardView class there or to your own custom keyboard class, add a method like the following. It overrides the onDraw() method and draws the background of the key defined with code 7 (in this case the "0") red and all the other keys blue. @Override
public void onDraw(Canvas canvas) {
super.onDraw(canvas);
List<Key> keys = getKeyboard().getKeys();
for (Key key : keys) {
if (key.codes[0] == 7) {
Log.e("KEY", "Drawing key with code " + key.codes[0]);
Drawable dr = (Drawable) context.getResources().getDrawable(R.drawable.red_tint);
dr.setBounds(key.x, key.y, key.x + key.width, key.y + key.height);
dr.draw(canvas);
} else {
Drawable dr = (Drawable) context.getResources().getDrawable(R.drawable.blue_tint);
dr.setBounds(key.x, key.y, key.x + key.width, key.y + key.height);
dr.draw(canvas);
}
}
}
@Override
public void onDraw(Canvas canvas) {
// super.onDraw(canvas);
List<Key> keys = getKeyboard().getKeys();
for (Key key : keys) {
if (key.codes[0] == 7) {
NinePatchDrawable npd
= (NinePatchDrawable) context.getResources().getDrawable(R.drawable.red_key);
npd.setBounds(key.x, key.y, key.x + key.width, key.y + key.height);
npd.draw(canvas);
} else {
NinePatchDrawable npd
= (NinePatchDrawable) context.getResources().getDrawable(R.drawable.blue_key);
npd.setBounds(key.x, key.y, key.x + key.width, key.y + key.height);
npd.draw(canvas);
}
Paint paint = new Paint();
paint.setTextAlign(Paint.Align.CENTER);
paint.setTextSize(48);
paint.setColor(Color.GRAY);
if (key.label != null) {
canvas.drawText(key.label.toString(), key.x + (key.width / 2),
key.y + (key.height / 2), paint);
} else {
key.icon.setBounds(key.x, key.y, key.x + key.width, key.y + key.height);
key.icon.draw(canvas);
}
}
}

Xamarin Forms. Keyboard on android covers bottom of an entry with custom background
Date : March 29 2020, 07:55 AM
may help you . I fixed it. The problem was with padding for entry. It was 0 for bottom and top. I set it as shown in following code: private void UpdatePadding(MessageEntry MessageEntry)
{
Control.SetPadding((int)Forms.Context.ToPixels(MessageEntry.LeftPadding), Control.PaddingTop/3,
(int)Forms.Context.ToPixels(MessageEntry.RightPadding), Control.PaddingTop/3);
}

Any of those help 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>
<fraction name="ten_keys_key_width">8.8%p</fraction>
