    • Method Detail

      • getOnChangedEnabled

         final Boolean getOnChangedEnabled()

        Enable or disable visibility changed event. Default is true, disable it if you don't need (triggered by every pixel scrolled).

      • setOnChangedEnabled

         final Unit setOnChangedEnabled(Boolean onChangedEnabled)

        Enable or disable visibility changed event. Default is true, disable it if you don't need (triggered by every pixel scrolled).

      • setPartialImpressionThresholdPercentage

         final Unit setPartialImpressionThresholdPercentage(@IntRange(from = 0.toLong(), to = 100.toLong()) Integer partialImpressionThresholdPercentage)

        Set the threshold of percentage visible area to identify the partial impression view state.

        Parameters:
        partialImpressionThresholdPercentage - Percentage of visible area of an element in the range 0..

      • attach

         final Unit attach(RecyclerView recyclerView)

        Attach the tracker.

        Parameters:
        recyclerView - The recyclerview that the EpoxyController has its adapter added to.

      • detach

         final Unit detach(RecyclerView recyclerView)

        Detach the tracker

        Parameters:
        recyclerView - The recycler view that the EpoxyController has its adapter added to.

      • clearVisibilityStates

         final Unit clearVisibilityStates()

        The tracker is storing visibility states internally and is using if to send events, only the difference is sent. Use this method to clear the states and thus regenerate the visibility events. This may be useful when you change the adapter on the RecyclerView.

      • requestVisibilityCheck

         final Unit requestVisibilityCheck()

        Calling this method will make the visibility tracking check and trigger events if necessary. It is particularly useful when the visibility of an Epoxy model is changed outside of an Epoxy RecyclerView.

        An example is when you nest an horizontal Epoxy backed RecyclerView in a non Epoxy vertical RecyclerView. When the vertical RecyclerView scroll you want to notify the visibility tracker attached on the horizontal RecyclerView.
