How to disable RecyclerView scrolling?

Question

I cannot disable scrolling in the RecyclerView. I tried calling rv.setEnabled(false) but I can still scroll.

How can I disable scrolling?

Answer 1

Add

android:descendantFocusability="blocksDescendants"

in your child of SrollView or NestedScrollView (and parent of ListView, recyclerview and gridview any one)

Answer 2

Just add this to your recycleview in xml

 android:nestedScrollingEnabled="false"

like this

<android.support.v7.widget.RecyclerView
                    android:background="#ffffff"
                    android:id="@+id/myrecycle"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:nestedScrollingEnabled="false">

Answer 3

There is a realy simple answer.

LinearLayoutManager lm = new LinearLayoutManager(getContext()) {
                @Override
                public boolean canScrollVertically() {
                    return false;
                }
            };

The above code disables RecyclerView vertically scrolling.

Answer 4

You should override the layoutmanager of your recycleview for this. This way it will only disable scrolling, none of ther other functionalities. You will still be able to handle click or any other touch events. For example:-

Original:

 public class CustomGridLayoutManager extends LinearLayoutManager {
 private boolean isScrollEnabled = true;

 public CustomGridLayoutManager(Context context) {
  super(context);
 }

 public void setScrollEnabled(boolean flag) {
  this.isScrollEnabled = flag;
 }

 @Override
 public boolean canScrollVertically() {
  //Similarly you can customize "canScrollHorizontally()" for managing horizontal scroll
  return isScrollEnabled && super.canScrollVertically();
 }
}

Here using "isScrollEnabled" flag you can enable/disable scrolling functionality of your recycle-view temporarily.

Also:

Simple override your existing implementation to disable scrolling and allow clicking.

 linearLayoutManager = new LinearLayoutManager(context) {
 @Override
 public boolean canScrollVertically() {
  return false;
 }
};

Answer 5

If you just disable only scroll functionality of RecyclerView then you can use setLayoutFrozen(true); method of RecyclerView. But it can not be disable touch event.

your_recyclerView.setLayoutFrozen(true);

Answer 6

Extend the LayoutManager and override canScrollHorizontally()and canScrollVertically() to disable scrolling.

Be aware that inserting items at the beginning will not automatically scroll back to the beginning, to get around this do something like:

  private void clampRecyclerViewScroll(final RecyclerView recyclerView)
  {
    recyclerView.getAdapter().registerAdapterDataObserver(new RecyclerView.AdapterDataObserver()
    {
      @Override
      public void onItemRangeInserted(int positionStart, int itemCount)
      {
        super.onItemRangeInserted(positionStart, itemCount);
        // maintain scroll position at top
        if (positionStart == 0)
        {
          RecyclerView.LayoutManager layoutManager = recyclerView.getLayoutManager();
          if (layoutManager instanceof GridLayoutManager)
          {
            ((GridLayoutManager) layoutManager).scrollToPositionWithOffset(0, 0);
          }else if(layoutManager instanceof LinearLayoutManager)
          {
            ((LinearLayoutManager) layoutManager).scrollToPositionWithOffset(0, 0);
          }
        }
      }
    });
  }
