Android 4.0 Sub-Title (section) Label Styling [closed]

Answer 1

Brandon's right; you'll need to do custom work for now to get the blue style, which is kind of frustrating since it's peppered throughout the new design guide.

Unfortunately, you can't reference Widget.Holo.Light.TextView.ListSeparator as a parent of a custom style, because it's private.

But if you're interested in just the gray line, you can use the stock Android style inline:

style="?android:attr/listSeparatorTextViewStyle"

This will at least get you to the gray line, all caps style:

Brandon's answer will get you to the custom blue style.

FYI, if you want to subclass exactly from the current (v15) Android style for List Separators, the combined styles used in Android for Widget.TextView.ListSeparator and Widget.Holo.Light.TextView.ListSeparator that you can copy over to a new style are:

<item name="android:background">@drawable/list_section_divider_holo_light</item>
<item name="android:textAllCaps">true</item>
<item name="android:layout_width">match_parent</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:textStyle">bold</item>
<item name="android:textColor">?android:textColorSecondary</item>
<item name="android:textSize">14sp</item>
<item name="android:gravity">center_vertical</item>
<item name="android:paddingLeft">8dip</item>

You'll have to copy the drawables over to your own directories though, since they're private.

I'm not sure exactly which style it is, but the preferences app uses that too (or something very similar). It's a section header. Also, the TextField has the textAllCaps set to true. You can probably find it in the resources folder of the SDK if you look for the textAllCaps :)

So this is what I ended up using:

<?xml version="1.0" encoding="utf-8"?>
<resources xmlns:android="http://schemas.android.com/apk/res/android">
    <style name="sectionHeader" parent="android:Widget.Holo.Light.TextView">
        <item name="android:drawableBottom">@drawable/section_header</item>
        <item name="android:drawablePadding">4dp</item>
        <item name="android:layout_marginTop">8dp</item>
        <item name="android:paddingLeft">4dp</item>
        <item name="android:textAllCaps">true</item>
        <item name="android:textColor">@color/emphasis</item>
        <item name="android:textSize">14sp</item>
    </style>
</resources>

Where @drawable/section_header is:

<?xml version="1.0" encoding="utf-8"?>
<shape
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">
    <size android:width="1000dp" android:height="2dp" />
    <solid 
        android:color="@color/emphasis"/>
</shape>

And @color's:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="emphasis">#31b6e7</color>
    <color name="bg_gray">#cecbce</color>
</resources>

I say, to draw the line just use a View, with height set tu 1dp or so. You can set the color using background attribute
