Well with Flex SDK 4.6 it is a possibility and very easy to do so.
Flex SDK 4.6 introduces many types of soft keyboard types, out of all those one type is type “Number”.
Generally we would want a numeric only keypad for text field where we are expecting people to fill only numeric values such as Age, Date of birth fields, IDs etc etc
Without wasting any more time lets see how this is done

<s:VGroup verticalAlign="middle"> |
|
1 2 3 |
<s:Label text="Numeric KeyBoard"/> <s:TextInput id="txtNumericKeyboard" softKeyboardType="number" width="120"/> </s:VGroup> |
If you want to specify whether a virtual keyboard should be displayed when this Interactive Object instance receives focus the you can set “needsSoftKeyboard” property to true so the above logic can be re written as

<s:VGroup verticalAlign="middle"> |
|
1 2 3 |
<s:Label text="Numeric KeyBoard"/> <s:TextInput id="txtNumericKeyboard" softKeyboardType="number" needsSoftKeyBoard="true" width="120"/> </s:VGroup> |

So now when you launch your application then you will get the numeric keypad when your textfield get the focus as shown below
