如何在NestedScrollView内使用RecyclerView ?

如何在NestedScrollView内使用RecyclerView ? 设置适配器后，RecyclerView内容不可见。

更新布局代码。

<android.support.v4.widget.NestedScrollView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical">

    <RelativeLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:padding="@dimen/keyline_1">

    </RelativeLayout>

    <View
        android:id="@+id/separator"
        android:layout_width="match_parent"
        android:layout_height="1dp"
        android:background="#e5e5e5" />

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

</LinearLayout>

</android.support.v4.widget.NestedScrollView>

            </LinearLayout>

        </androidx.core.widget.NestedScrollView>
    </LinearLayout>

</layout>

这里使用recyclerview的属性

app:layout_behavior="@string/appbar_scrolling_view_behavior"

并像这样关闭recyclerview嵌套滚动

android:nestedScrollingEnabled="false"

            </LinearLayout>

        </androidx.core.widget.NestedScrollView>
    </LinearLayout>

</layout>

这里使用recyclerview的属性

app:layout_behavior="@string/appbar_scrolling_view_behavior"

并像这样关闭recyclerview嵌套滚动

android:nestedScrollingEnabled="false"

保持recyclerview的回收特性并避免recyclerview加载所有数据的一个解决方案是在recyclerview本身设置一个固定的高度。通过这样做，recyclerview只能加载它的高度所能显示给用户的东西，这样当你滚动到底部/顶部时，循环它的元素。

就我而言，这对我很有效

将android:fillViewport="true"放入NestedScrollView中。 使RecyclerView的高度为wrap_content，即android:layout_height="wrap_content" 将此添加到RecyclerView android:nestedScrollingEnabled="false"

OR

以编程方式，在Kotlin类中

recyclerView。isNestedScrollingEnabled = false

mRecyclerView.setHasFixedSize(假)

有一个简单的测试代码，你可以检查

<android.support.v4.widget.NestedScrollView
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:fillViewport="true"
     app:layout_behavior="@string/appbar_scrolling_view_behavior">
    <android.support.v7.widget.RecyclerView
           android:layout_width="match_parent"
           android:layout_height="match_parent"/>
   </android.support.v4.widget.NestedScrollView>
2016-09-24 07:04:41

如果你在NestedScrollView中使用RecyclerView ScrollListener, addOnScrollListener监听器不能正常工作。

使用这段代码。

recyclerView.addOnScrollListener(new RecyclerView.OnScrollListener() {
        @Override
        public void onScrollStateChanged(@NonNull RecyclerView recyclerView, int newState) {
            super.onScrollStateChanged(recyclerView, newState); 
              ......
        }
    });

这段代码工作良好的RecyclerView ScrollListener内的NestedScrollView。

谢谢
