Question

The blue shadow over scroll effect looks really ugly in our app.
Is there a way to disable all the over scroll effect? You know there are lots of ScrollViews and Lists in it… That would be a shame if I have to disable it in every widget that can
scroll…
thx~

You can define a ScrollViewStyle and ListViewStyle in your Theme:

<style name="Theme.MyTheme" parent="android:Theme.Holo">
    <item name="android:listViewStyle">@style/Widget.MyTheme.ListView</item>
    <item name="android:scrollViewStyle">@style/Widget.MyTheme.ScrollView</item>
</style>

<style name="Widget.MyTheme.ListView" parent="android:Widget.ListView">
    <item name="android:overScrollMode">never</item>
</style>

<style name="Widget.MyTheme.ScrollView" parent="android:Widget.ScrollView">
    <item name="android:overScrollMode">never</item>
</style>

Then you have to define your Theme in you AndroidManifest.xml:

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="ch.citux.example"
      android:versionCode="1"
      android:versionName="1.0">

<uses-sdk android:targetSdkVersion="16" android:minSdkVersion="8"/>

<application
        android:hardwareAccelerated="true"
        android:label="@string/app_name"
        android:icon="@drawable/ic_launcher"
        android:theme="@style/Theme.MyTheme">

That’s it, no more overscroll 😉
