• RecyclerView嵌套ScrollView导致RecyclerView内容显示不全


    我们在使用RecyclerView嵌套至ScrollView内的时候

    RecyclerView不在屏幕内的数据会不显示出来,这里是一个坑,我们需要重写RecyclerView

    /**

     */
    public class MyRecyclerView extends RecyclerView {
    
        public MyRecyclerView(@NonNull Context context) {
            super(context);
        }
    
        public MyRecyclerView(Context context, AttributeSet attrs) {
            super(context, attrs);
        }
    
        public MyRecyclerView(Context context, AttributeSet attrs, int defStyleAttr) {
            super(context, attrs, defStyleAttr);
        }
    
    
        @Override
        public boolean canScrollVertically(int direction) {
            return false;
        }
    
        @Override
        public boolean canScrollHorizontally(int direction) {
            return false;
        }
    }

    即 canScrollVertically 和 canScrollHorizontally这两个方法返回为false

    而且需要在RecyclerView外层包裹一个RelativeLayout

    这样重新运行下,就能显示出来了

            <ScrollView
                android:id="@+id/scrollView_right_up"
                android:layout_width="match_parent"
                android:scrollbars="none"
                android:layout_height="wrap_content">
    
                <RelativeLayout
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content">
    
                    <demo.MyRecyclerView
                        android:id="@+id/recyclerview_right_up"
                        android:layout_width="match_parent"
                        android:layout_height="40dp">
    
                    </demo.MyRecyclerView>
    
                </RelativeLayout>
    
    
    
            </ScrollView>
