Setting a style on dynamically created view control

How do I set a TextView or Button style in code?
Styling within Android allows you to define a reusable look-and-feel, much like styles in CSS on a web page. These are very easy to assign in your XML layouts, however you cannot set the style of a View control programmatically. This is a pain if you are building a layout dynamically.

To get around this you can create a template layout xml file with the style assigned, for example in res/layout create tvtemplate.xml as with the following content:

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android=""
        android:text="This is a template"
        style="@style/my_style" />

then inflate this to instantiate your new TextView:

TextView myText = (TextView)getLayoutInflater().inflate(R.layout.tvtemplate, null);

You can then continue to work with your TextView as usual. There may be other workarounds for this, if you have any please feel free to comment. It's also possible that an Android API update will add a property for this in future.
