You try this way

listView.setOnScrollListener(new OnScrollListener() {

@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
}

@Override
public void onScroll(AbsListView view, int firstVisibleItem,
        int visibleItemCount, int totalItemCount) {
    boolean enable = false;
    if(listView != null && listView.getChildCount() > 0){
        // check if the first item of the list is visible
        boolean firstItemVisible = listView.getFirstVisiblePosition() == 0;
        // check if the top of the first item is visible
        boolean topOfFirstItemVisible = listView.getChildAt(0).getTop() == 0;
        // enabling or disabling the refresh layout
        enable = firstItemVisible && topOfFirstItemVisible;
    }
    swipeRefreshLayout.setEnabled(enable);
}});

This code doesn't work if listView has paddingTop

After my trial and error, I found one solution from

http://www.dailydevbook.de/android-swiperefreshlayout-without-overscroll/

For people who can implement SwipeRefreshLayout, in order to achieve it

STEP 1: DOWNLOAD android-support v4 (Open Source) from github

android-support v4 - Download Link

STEP 2: COPY following java class to your project src

SwipeRefreshLayout
SwipeProgressBar
BakedBezierInterpolator

note1- (Refactor SwipeRefreshLayout to mySwipeRefreshLayout to prevent confusing with original) note2- (Fix these classes and use the source from each other instead of v4)

STEP 3: UPDATE CODE use

mySwipeRefreshLayout instead of
SwipeRefreshLayout

STEP 4: UPDATE LAYOUT use

com.yourpackage.mySwipeRefreshLaout instead of
android.support.v4.widget.SwipeRefreshLayout

STEP 5: In your mySwipeRefreshLayout.java, find and change to a following code

private  void  updateContentOffsetTop ( int  targetTop) {
        final  int  currentTop = mTarget.getTop ();
        if  (targetTop> mDistanceToTriggerSync) {
            targetTop = ( int ) mDistanceToTriggerSync;
        } else  if  (targetTop < 0 ) {
            targetTop = 0 ;
        }
        // SetTargetOffsetTopAndBottom (targetTop - currentTop);
        setTargetOffsetTopAndBottom ( 0 ); // MOD: Prevent Scroll Down Animation
    }

Thanks to Jongz Puangput for the workaround, but I want to suggest another solution, that I find simplier.

In order to prevent pull down of the SwipeRefreshLayout's child you can provide your own child view with overriden offsetTopAndBottom method like this:

public class FixedRelativeLayout extends RelativeLayout {

    ...

    @Override
    public void offsetTopAndBottom(int offset) {
        // Ignoring movement from SwipeRefreshLayout
        super.offsetTopAndBottom(0);
    }

}

That works for me, hope it'll help anybody.

I was also facing same issue. try this:

guidesList.setOnScrollListener(new AbsListView.OnScrollListener() {  
    @Override
    public void onScrollStateChanged(AbsListView view, int scrollState) {
    }

    @Override
    public void onScroll(AbsListView view, int firstVisibleItem, int   visibleItemCount, int totalItemCount) {

        int topRowVerticalPosition = (guidesList == null || 
            guidesList.getChildCount() == 0) ? 0 : guidesList.getChildAt(0).getTop();

        swipeContainer.setEnabled(firstVisibleItem == 0 && topRowVerticalPosition >= 0);
    }
});

You can find out the recycler view currently at the top and by knowing that you can disable or enable SwipeRefreshLayout, let me give an example

let's say you use linear layout manager or grid then you can find out the recycler position from there

        LinearLayoutManager mLayoutManager;
        if (mColumnCount <= 1) {
            mLayoutManager = new LinearLayoutManager(getBaseContext());
        } else {
            mLayoutManager = new GridLayoutManager(getBaseContext(), mColumnCount);
        }

        recyclerAdapter = new RecyclerViewAdapter(allData);
        mRecycler.setAdapter(recyclerAdapter);
        mRecycler.setLayoutManager(layoutManager);

        if (mLayoutManager.findFirstCompletelyVisibleItemPosition() == 0) {
            swipeRefreshLayout.setEnabled(true);
        }
        else{
            swipeRefreshLayout.setEnabled(false);
        }

so your recycler scroll will work fine and if reach the top the swipeRefreshLayout handle the refresh event...
