A number keyboard has nearly full function of System Keyboard.
I only focus to create a number decimal keyboard, But I have implemented some event to get usefully for my keyboard.
I hope you will get more benefit from it, so you can custom a owner keyboard with text only, number un-sign only, phone only, password only ... etc.
height of keyboard will equal 1/3 screen height. you can set height with new number if you want
<com.taindb.library.NumberKeyboardLayout
android:id="@+id/numberKeyBoard"
android:layout_gravity="bottom"
android:layout_width="match_parent"
android:layout_height="wrap_content"/>
