NestedScrollView中的RecyclerView-滚动无法正常工作

我已经尝试了StackOverflow中提供的许多解决方案,但该解决方案无法满足我的期望。我想禁用“回收者视图滚动”,仅允许嵌套的scrollView滚动我的内容。

下面是我的XML:

在我的活动中,我将其设置为禁用回收站视图滚动

private void setupListing() {
    // rvMenuList should not be null
    assert rvListing != null;
    // initialize Recycler View Adapter
    userListingAdapter = new UserListingAdapter(getContext());

    // initialize GridLayoutManager
    GridLayoutManager gridLayoutManager = new GridLayoutManager(getContext(), gridSize);
    // initialize custom divider item decorator
    SpacesItemDecoration itemDecorator = new SpacesItemDecoration(10, 10, 30);
    rvListing.addItemDecoration(itemDecorator);

    ViewCompat.setNestedScrollingEnabled(rvListing, false);
    // set the adapter to the recycler view
    rvListing.setAdapter(userListingAdapter);
    // set the layout manager to the recycler view
    rvListing.setLayoutManager(gridLayoutManager);
}

这是它的样子

现在,由于使用了这段代码ViewCompat.setNestedScrollingEnabled(rvListing, false);,我无法滚动回收器视图,而且我也无法滚动全部内容来查看回收器视图的其他项目。

这可能对您有用,请应用布局行为:

<android.support.v7.widget.RecyclerView
    android:id="@+id/conversation"
    app:layout_behavior="@string/appbar_scrolling_view_behavior"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

答案 1 :(得分:0)

代替使用此行:

ViewCompat.setNestedScrollingEnabled(rvListing, false);

使用以下行:

rvListing.setNestedScrollingEnabled(false);

像这样设置适配器后

private void setupListing() {
    // rvMenuList should not be null
    assert rvListing != null;
    // initialize Recycler View Adapter
    userListingAdapter = new UserListingAdapter(getContext());

    // initialize GridLayoutManager
    GridLayoutManager gridLayoutManager = new GridLayoutManager(getContext(), gridSize);
    // initialize custom divider item decorator
    SpacesItemDecoration itemDecorator = new SpacesItemDecoration(10, 10, 30);
    rvListing.addItemDecoration(itemDecorator);
 // set the adapter to the recycler view
    rvListing.setAdapter(userListingAdapter);
    // set the layout manager to the recycler view
    rvListing.setLayoutManager(gridLayoutManager);
    rvListing.setHasFixedSize(true);

    rvListing.setNestedScrollingEnabled(false);

}

使用RecyclerView宽度

android:layout_height="wrap_content"

最终得到了解决方案。 rvListing.setNestedScrollingEnabled(false);实际上有效。问题是父母身高,我不小心将其设置为0dp。这就是解决此问题的方法。

答案 3 :(得分:-1)

只需按如下所示重写GridLayoutManager,然后调用方法setCanScroll(false)。

public class CustomLayoutManager extends GridLayoutManager {

private boolean canScroll;

public CustomLayoutManager(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {
    super(context, attrs, defStyleAttr, defStyleRes);
}


/**
 * 
 * @param canScroll true--enable scroll, false--disable scroll
 */
public void setCanScroll(boolean canScroll) {
    this.canScroll = canScroll;
}

@Override
public boolean canScrollHorizontally() {
    return this.canScroll;
}

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

}

要禁用RecyclerView的滚动,您可以通过编程方式进行:

recyclerView.setNestedScrollingEnabled(false);

或通过xml

 <android.support.v7.widget.RecyclerView
  android:nestedScrollingEnabled="false"
  android:layout_width="match_parent"
  android:layout_height="match_parent"/>

但是当您的RecyclerView包含很多物品时要小心。会导致滞后

禁用RecyclerView滚动是一种不好的做法,请将RecyclerView与多种项目类型结合使用!
