Changing the style of the standard android.R.layout options?

Is it possible to override the standard layouts that are provided with Android? Is it for example possible to make the text smaller for android.R.layout.simple_list_item_checked? Or would I simply need to make my own layout to do this? Thanks.

Yes, it is. Here's a similar thing being accomplished (res/values/styles.xml):

<?xml version="1.0" encoding="utf-8"?>
<resources>
<style name="ContactLabelTextView">
    <item name="android:layout_width">wrap_content</item>
    <item name="android:layout_height">wrap_content</item>
    <item name="android:gravity">right</item>
    <item name="android:textSize">14sp</item>
    <item name="android:textColor">@android:color/white</item>
    <item name="android:layout_marginLeft">5dp</item>
    <item name="android:layout_marginRight">5dp</item>
    <item name="android:layout_marginTop">5dp</item>
  </style>
  <style name="questionTableRow">
      <item name="android:layout_width">wrap_content</item>
      <item name="android:layout_height">wrap_content</item>
      <item name="android:layout_margin">5dp</item>
      <item name="android:layout_marginLeft">5dp</item>
      <item name="android:background">@drawable/textview_border</item>
  </style> 
</resources>

And then, when you want to apply the style to an element in the layout file that you have created (main.xml, res/layout/your_custom_layout.xml): 

<?xml version="1.0" encoding="utf-8"?>
    <TableRow
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/questionTableRow"
        style="@style/questionTableRow"

Obviously you are looking to accomplish this with a textView. I provided an example of my own code where the textView gets a specific style. I actually don't even have that textView style applied, but I pasted in where I applied a style to a tableRow, just so you see how to apply it to an xml element.

Does this do what you need?

You have to make your own layout. In order to make a custom layout and use a standard adapter (like ArrayAdapter) you have to specifiy the same id(s) in your custom layout as in the standard layouts. For example the TextView in simple_list_item_checked has the id "@android:id/text1" (http://www.devdaily.com/java/jwarehouse/android-examples/platforms/android-2/data/res/layout/simple_list_item_checked.xml.shtml). In your custom layout you specify that id. Thus you do not have to write a custom adapter. So the best way is just by copying the standard xml layout and change what you wanne change
