Advanced Usage
<com.chauthai.overscroll.RecyclerViewBouncy
android:id="@+id/recyclerView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:tension="1000"
app:friction="200"
app:gapLimit="220"
app:speedFactor="5"
app:viewCountEstimateSize="5"
app:maxAdapterSizeToEstimate="20"/>Optional params:
tensionTension of the spring. It should be set to a high value (ex. 1000) for smooth animation.frictionFriction of the spring. High friction value will slow down the scroll-back speed.gapLimitThe maximum over-scroll gap size (in dp). The default value is 220dp.speedFactorThe higher the speedFactor is, the less the view will utilize the gap limit. Minimum value is 1.viewCountEstimateSize(for RecyclerView/Listview) The number of children views to estimate the content size of RecyclerView (or ListView). The estimation is computed by averaging the children views size then multiply by the total items inside the adapter.maxAdapterSizeToEstimate(for RecyclerView/Listview) The maximum adapter size (number of items in the adapter) that the system will include content size estimation of the RecyclerView (or ListView) in the calculation.
