# appbarlayout-spring-behavior

One library contains one behavior help appbarlayout to scroll spring. In the sample have add the realtimeblur test and add tablayout with TabScrimHelper(animate color with CollapsingToolbarLayout).Because of some methods in the Behavior of AppBarLayout not open to the out package. So I set the package name same to the support design.

Usages

====

#### AppBarLayout-Spring

```xml

        ...

```

if you want add blur with the spring.You can add this by the [RealtimeBlurView](https://github.com/mmin18/RealtimeBlurView):

```java

final RealtimeBlurView realtimeBlurView = (RealtimeBlurView) findViewById(R.id.real_time_blur_view);

AppBarLayout appBarLayout = (AppBarLayout) findViewById(R.id.app_bar);

AppBarLayoutSpringBehavior springBehavior = (AppBarLayoutSpringBehavior) ((CoordinatorLayout.LayoutParams) appBarLayout.getLayoutParams()).getBehavior();

springBehavior.setSpringOffsetCallback(new AppBarLayoutSpringBehavior.SpringOffsetCallback() {

      @Override

      public void springCallback(int offset) {

           int radius = 20 * (240 - offset > 0 ? 240 - offset : 0) / 240;

           realtimeBlurView.setBlurRadius(radius);

      }

});

```

With the tablayout you can add **TabScrimHelper** to let TabLayout animate color with the CollapsingToolbarLayout:

```java

TabScrimHelper tabScrimHelper = new TabScrimHelper(tabLayout, collapsingToolbarLayout);

appBarLayout.addOnOffsetChangedListener(tabScrimHelper);

```
