Is the default value of textAppearance in android:theme="@style/AppTheme" textAppearanceSmall?

When I create a new android project,the default Theme is android:Theme.Light, I find the font size of TextView control is small, does it mean the default value of textAppearance in android:theme="@style/AppTheme" is textAppearanceSmall? Thanks!

<style name="AppBaseTheme" parent="android:Theme.Light">
        <!--
            Theme customizations available in newer API levels can go in
            res/values-vXX/styles.xml, while customizations related to
            backward-compatibility can go here.
        -->
</style>

The TextView doesn't take the default textAppearance, it is set to be explicitly to use textAppearanceSmall by default.

Themes.xml contains the following line which defines default style for the TextView:

<item name="textViewStyle">@android:style/Widget.TextView</item>

The referenced style contains the following line:

<item name="android:textAppearance">?android:attr/textAppearanceSmall</item>

This is why TextView defaults to small text size.

You can find the styles used for all the Android widgets on the default styles.xml file. You can have a look to this file for example here: https://github.com/android/platform_frameworks_base/blob/master/core/res/res/values/styles.xml

Or directly into your SDK folder, for example on my computer it is available here: D:\Dev\android-sdk\platforms\android-17\data\res\values\styles.xml

You will find in this file the definition of the style for the TextView:

<style name="Widget.TextView">
    <item name="android:textAppearance">?android:attr/textAppearanceSmall</item>
    <item name="android:textSelectHandleLeft">?android:attr/textSelectHandleLeft</item>
    <item name="android:textSelectHandleRight">?android:attr/textSelectHandleRight</item>
    <item name="android:textSelectHandle">?android:attr/textSelectHandle</item>
    <item name="android:textEditPasteWindowLayout">?android:attr/textEditPasteWindowLayout</item>
    <item name="android:textEditNoPasteWindowLayout">?android:attr/textEditNoPasteWindowLayout</item>
    <item name="android:textEditSidePasteWindowLayout">?android:attr/textEditSidePasteWindowLayout</item>
    <item name="android:textEditSideNoPasteWindowLayout">?android:attr/textEditSideNoPasteWindowLayout</item>
    <item name="android:textEditSuggestionItemLayout">?android:attr/textEditSuggestionItemLayout</item>
    <item name="android:textCursorDrawable">?android:attr/textCursorDrawable</item>
</style>

You can see that indeed in this file the text size is defined with textAppearanceSmall by default.
