Example 9 with LayoutManager

use of android.support.v7.widget.RecyclerView.LayoutManager in project FlexibleAdapter by davideas.

the class FragmentStaggeredLayout method initializeRecyclerView.

@SuppressWarnings({ "ConstantConditions", "NullableProblems" })

    // and to assign it again to the RecyclerView!
    TopSnappedSmoothScroller.MILLISECONDS_PER_INCH = 33f;
    mRecyclerView.setLayoutManager(createNewStaggeredGridLayoutManager());
    // This value is restored to 100f (default) right here, because it is used in the
    // constructor by Android. If we don't change it now, others LayoutManager will be
    // impacted too by the above modification!

    mRecyclerView.setAdapter(mAdapter);
    //Size of RV will not change
    mRecyclerView.setHasFixedSize(true);

    // a Payload is provided. FlexibleAdapter is actually sending Payloads onItemChange.

    // Experimenting NEW features (v5.0.0)
    //Show Headers at startUp!
