I have a horizontal MultiSnapRV, my XML code:

<com.takusemba.multisnaprecyclerview.MultiSnapRecyclerView
        android:id="@+id/rv_weeks"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="center"
        app:msrv_gravity="start"
        app:msrv_snap_count="7" />

When I scroll it forward, it works amazing and smooth. But if I scroll backward, sometimes it scrolls 14 positions, not 7. Is it bug or I missed something?

It was able to snap last item at v1.3.4, however after upgrading to v2.0.1 it will bounce back to the previous item rather than focus on the last item.

When running the app, it throws "java.lang.IllegalArgumentException: other than LinearLayoutManger is not supported" being that at onAttachedToWindow, mLayout is null therefore is not an instance of LinearLayoutManager.

So what's happening here?

Hi TakuSemba,

After attaching your code the recycler scroll works too slow. Either it's just scroll to msrv_snap_count or if we define higher value then it skips all the items.

A warning appears when i swipe from the recyclerview. The test machine is the Nexus 5x android 7.0 version api 24. Can I ignore it?

E/RecyclerView: Smooth Scroll action is being updated too frequently. Make sure you are not changing it unless necessary

Hi, thank you for the request.

I'm just wondering if recyclerView.smoothScrollToPosition(position) does not work for your case? It would be helpful if you could give me a situation you want to scroll with `SnapHelpe

I found a bug where the list is preventing the last item to be shown when app:msrv_gravity="start" is set.

Screen recording of issue with library's sample app: end not snapping with gravity start normal font.mp4.zip

Phone: OnePlus One Android Version: 6.0.1

Edit Apparently this happens to first item when app:msrv_gravity="start" is set with app:msrv_interval="2"

Gravity: Center Snap Count: 1 Orientation: Vertical Portrait: showing multiple items depends on the item height Landscape: showing one item in fullscreen I did recycler_view.scrollToPosition() in onConfigurationChanged. Portrait -> Landscape is working fine Landscape -> Portrait: the item is in top, instead of center, until you scroll again

use MultiSnapRecyclerView in a RecyclerView item

                MultiSnapRecyclerView snapRecyclerView = null;
                SkipAppAdapter appAdapter = new SkipAppAdapter(snapRecyclerView, data.getFastInDataBean());
                snapRecyclerView = holder.getView(R.id.snapRecycleView);
                LinearLayoutManager layoutManager = new LinearLayoutManager(getContext(), LinearLayoutManager.HORIZONTAL, false);
                snapRecyclerView.setLayoutManager(layoutManager);
                snapRecyclerView.setAdapter(appAdapter);

                snapRecyclerView.setOnSnapListener(new OnSnapListener() {
                    @Override
                    public void snapped() {
                        // do something
                    }
                });

Hi,

One more enhancement, if we click on any item of the RecyclerView then snap the selected position.

I.e. we can snap via two modes, one by touching the item or by scrolling to it.

sorry, I forgot to upload jar to jCenter. for now, you have to use this library importing through my maven repository like this

// set marven url
repositories {
  maven { url 'https://dl.bintray.com/takusemba/maven' }
}

// compile library in dependencies
dependencies {
    compile 'com.github.takusemba:multisnaprecyclerview:x.x.x'
}

Im adding this to jCenter now. After few hours you can import this library just like this below

dependencies {
    compile 'com.github.takusemba:multisnaprecyclerview:x.x.x'
}

Shell or other controller

Hello and thank you for your library, it helped me a lot! However, I found an issue in your implementation. In fact there are two issues in one:

1. ms/inch is not a speed, it's inversion of speed, so the word "speed" in the attribute name is very confusing;
2. It would be better to have some alternative attribute to define constant snap time.

I'll explain the second issue as it is more important. If you swipe your recyclerview on a small screen in portrait mode with (for example) msrv_speed_ms_per_inch=50, it will change the page pretty fast. But if you'll try it on a bigger device (on a tablet), it will scroll really slow, because it has a larger surface and it takes more time to reach target point.

Instead, it would be better to declare a constant time for snap helper, that will be equally fast on both devices.
