ScrollView里面的无限RecyclerView？

Question

我想要一个包含ViewPager和RecyclerView的布局。但在NestedScrollview内，ViewPager不滚动RecyclerView。

Answer 1

根据列表中的项目数量，您必须给出RecyclerView的固定高度。使用以下函数计算ListView高度。

public static void setListViewHeightBasedOnChildren(ListView listView) { 
    ListAdapter listAdapter = listView.getAdapter(); 
    if (listAdapter == null) { 
     // pre-condition 
     return; 
    } 

    int totalHeight = 0; 
    for (int i = 0; i < listAdapter.getCount(); i++) { 
     View listItem = listAdapter.getView(i, null, listView); 
     listItem.measure(0, 0); 
     totalHeight += listItem.getMeasuredHeight(); 
    } 

    ViewGroup.LayoutParams params = listView.getLayoutParams(); 
    params.height = totalHeight + (listView.getDividerHeight() * (listAdapter.getCount() - 1)); 
    listView.setLayoutParams(params); 
    listView.requestLayout(); 
} 

and 

setListViewHeightBasedOnChildren(recyclerView);
