Examples with AdapterDataObserver androidx.recyclerview.widget.RecyclerView.AdapterDataObserver used on opensource projects

Example 1 with AdapterDataObserver

use of androidx.recyclerview.widget.RecyclerView.AdapterDataObserver in project epoxy by airbnb.

the class ModelClickListenerTest method modelClickListenerIsDiffed.

@Test
public void modelClickListenerIsDiffed() {
    // Internally we wrap the model click listener with an anonymous click listener. We can't hash
    // the anonymous click listener since that changes the model state, instead our anonymous
    // click listener should use the hashCode of the user's click listener
    ModelClickListener modelClickListener = new ModelClickListener();
    ViewClickListener viewClickListener = new ViewClickListener();
    TestController controller = new TestController();
    AdapterDataObserver observerMock = mock(AdapterDataObserver.class);
    controller.getAdapter().registerAdapterDataObserver(observerMock);
    ModelWithClickListener_ model = new ModelWithClickListener_();
    controller.setModel(model);
    controller.requestModelBuild();
    verify(observerMock).onItemRangeInserted(eq(0), eq(1));
    model = new ModelWithClickListener_();
    model.clickListener(modelClickListener);
    controller.setModel(model);
    lifecycleHelper.buildModelsAndBind(controller);
    // The second update shouldn't cause a item change
    model = new ModelWithClickListener_();
    model.clickListener(modelClickListener);
    controller.setModel(model);
    lifecycleHelper.buildModelsAndBind(controller);
    model = new ModelWithClickListener_();
    model.clickListener(viewClickListener);
    controller.setModel(model);
    lifecycleHelper.buildModelsAndBind(controller);
    verify(observerMock, times(2)).onItemRangeChanged(eq(0), eq(1), any());
    verifyNoMoreInteractions(observerMock);
}
