FadingActionBar is a library which implements the cool fading action bar effect that can be seen in the new Play Music app.

This library uses the techniques outlined by Cyril Mottier in a popular blog post.

The three most commonly used action bar implementations are supported: stock (API 11+), ActionBarCompat and ActionBarSherlock.

Try out the sample application:

Or browse the source code of the sample application for a complete example of use.

The library is pushed to Maven Central as a AAR, so you just need to add the following dependency to your build.gradle.

dependencies {
    compile 'com.github.manuelpeinado.fadingactionbar:fadingactionbar:3.1.2'
}

If your project doesn't use the stock action bar, but one of the compatibility implementations, you would use the following:

dependencies {
    // Use the following if your project uses ActionBarCompat
    compile 'com.github.manuelpeinado.fadingactionbar:fadingactionbar-abc:3.1.2'
    // Or the following if your project uses ActionBarSherlock
    compile 'com.github.manuelpeinado.fadingactionbar:fadingactionbar-abs:3.1.2'
}

Using the library is really simple, just look at the source code of the provided samples:

• If your content should be in a ScrollView.
• If your content should be in a ListView.
• If your content is a WebView.

You can even use the library from a fragment, which is useful when implementing a dual phone/tablet layout.

See the demos included in the sample application for a complete overview of the features supported by the library.

There is an important issue with the library and ListViews. More specifically, things don't work quite right when the activity is re-created due to a configuration change. So, unless you handle configuration changes yourself (or your activity is portrait/landscape only), I strongly suggest you stick to having your content in a ScrollView until a solution to this issue is found.
