java NestedScrollView 没有在里面放 Recyclerview

NestedScrollView not fling with Recyclerview inside

提问by Khang .NT

I have a layout like that:

我有这样的布局：

<NestedScrollView>
     <RecyclerView> // vertical recycler view
          <RecyclerView/>  // horizontal recycler view
          <RecyclerView/>
          <RecyclerView/>
          ...
     <RecyclerView>
</NestedScrollView>

The result looks like Google play store:

结果看起来像 Google Play 商店：

And I disabled NestedScrolling in horizontal Recyclerview:

我在horizontal Recycler视图中禁用了 NestedScrolling ：

horizontalRecyclerView.setHasFixedSize(true);
horizontalRecyclerView.setNestedScrollingEnabled(false);

My problem:

我的问题：

The vertical recyclerviewdoes not scroll fling, whenever ACTION_UPhappen, the vertical recyclerviewalso stop scrolling.

在vertical recyclerview不滚动一扔，每当ACTION_UP发生了，vertical recyclerview也停止滚动。

How can I nest vertical recyclerviewinside nestedscrollview, and horizontal recyclerviewinside vertical recyclerviewlike Playstore and keep the scroll smooth.

我怎么能窝vertical recyclerview内nestedscrollview，和horizontal recyclerview里面vertical recyclerview像Play商店中，并保持滚动顺畅。

Solved:

解决了：

Using custom nested scroll view of @vrund purohit (code below), and disabled nestedscroll both vertical and horizontal recyclerview:

使用@vrund purohit 的自定义嵌套滚动视图（下面的代码），并禁用了垂直和水平回收器视图的nestedscroll：

verticalRecyclerView.setNestedScrollingEnabled(false);
... add each horizontal recyclerviews:
horizontalRecyclerView.setNestedScrollingEnabled(false);

I had this same problem and I solved this issue by customizing NeatedScrollView.

我遇到了同样的问题，我通过自定义NeatedScrollView.

Here is the class for that.

这是课程。

MyNestedScrollView

我的嵌套滚动视图

public class MyNestedScrollView extends NestedScrollView {
    @SuppressWarnings("unused")
    private int slop;
    @SuppressWarnings("unused")
    private float mInitialMotionX;
    @SuppressWarnings("unused")
    private float mInitialMotionY;
    public MyNestedScrollView(Context context) {
        super(context);
        init(context);
    }
    private void init(Context context) {
        ViewConfiguration config = ViewConfiguration.get(context);
        slop = config.getScaledEdgeSlop();
    }
    public MyNestedScrollView(Context context, AttributeSet attrs) {
        super(context, attrs);
        init(context);
    }
    public MyNestedScrollView(Context context, AttributeSet attrs,
            int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        init(context);
    }
    private float xDistance, yDistance, lastX, lastY;
    @SuppressWarnings("unused")
    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        final float x = ev.getX();
        final float y = ev.getY();
        switch (ev.getAction()) {
        case MotionEvent.ACTION_DOWN:
            xDistance = yDistance = 0f;
            lastX = ev.getX();
            lastY = ev.getY();
            // This is very important line that fixes
            computeScroll();
            break;
        case MotionEvent.ACTION_MOVE:
            final float curX = ev.getX();
            final float curY = ev.getY();
            xDistance += Math.abs(curX - lastX);
            yDistance += Math.abs(curY - lastY);
            lastX = curX;
            lastY = curY;
            if (xDistance > yDistance) {
                return false;
            }
        }
        return super.onInterceptTouchEvent(ev);
    }
    public interface OnScrollChangedListener {
        void onScrollChanged(NestedScrollView who, int l, int t, int oldl,
                int oldt);
    }
    private OnScrollChangedListener mOnScrollChangedListener;
    public void setOnScrollChangedListener(OnScrollChangedListener listener) {
        mOnScrollChangedListener = listener;
    }
    @Override
    protected void onScrollChanged(int l, int t, int oldl, int oldt) {
        super.onScrollChanged(l, t, oldl, oldt);
        if (mOnScrollChangedListener != null) {
            mOnScrollChangedListener.onScrollChanged(this, l, t, oldl, oldt);
        }
    }
}

Happy coding.

[RESOLVED] I have same issue with Horizontal recycleview. Change Gradle repo for recycleview

[已解决] 我对 Horizo​​ntal recycleview 有同样的问题。更改 Gradle repo 以进行 recycleview

compile 'com.android.support:recyclerview-v7:23.2.1' Write this: linearLayoutManager.setAutoMeasureEnabled(true);

编译 'com.android.support:recyclerview-v7:23.2.1' 写这个：linearLayoutManager.setAutoMeasureEnabled(true);

I have found issue with 23.2.1 library: When item is match_parent recycle view fill full item to view, please always go with min height or "wrap_content".

我发现了 23.2.1 库的问题：当项目是 match_parent 回收视图填充完整项目以查看时，请始终使用最小高度或“wrap_content”。

I've solved the issue by using below code:

我已经使用下面的代码解决了这个问题：

        myRecyclerView.setLayoutManager(new LinearLayoutManager(getContext(), LinearLayoutManager.VERTICAL, false){
        @Override
        public boolean canScrollHorizontally() {
            return true;
        }

        @Override
        public boolean canScrollVertically() {
            return true;
        }
    });
