Java 将列表视图添加到LinearLayout，但仅显示第一个添加的视图

我试图向linearlayout添加两个Listview，但只显示第一个Listview，有人知道为什么吗

private void populateListView(ConstraintLayout root, List<Product> products){
    ....

    ConstraintLayout.LayoutParams newParams = new ConstraintLayout.LayoutParams(
            ConstraintLayout.LayoutParams.MATCH_PARENT, ConstraintLayout.LayoutParams.MATCH_PARENT);

    ...
    ListView listView = (ListView)getLayoutInflater().inflate(R.layout.list_view_product, null);
    listView.setId(View.generateViewId());
    listView.setLayoutParams(newParams);
    ...

   
    ListView listView2 = (ListView)getLayoutInflater().inflate(R.layout.list_view_product, null);
    listView2.setId(View.generateViewId());
    listView2.setLayoutParams(newParams);
    ...

    LinearLayout linearLayoutView = (LinearLayout)root.findViewById(R.id.fragment_ll_home);

    linearLayoutView.addView(listView2,0);
    linearLayoutView.addView(listView,1);

}

private void populateListView（ConstraintLayout根目录，列出产品）{
....
ConstraintLayout.LayoutParams newParams=新的ConstraintLayout.LayoutParams(
ConstraintLayout.LayoutParams.MATCH_父级，ConstraintLayout.LayoutParams.MATCH_父级）；
...
ListView ListView=（ListView）GetLayoutFlater（）.充气（R.layout.list\u view\u product，null）；
setId（View.generateViewId（））；
setLayoutParams（newParams）；
...
ListView listView2=（ListView）GetLayoutFlater（）.充气（R.layout.list\u view\u product，null）；
setId（View.generateView（））；
listView2.setLayoutParams（新参数）；
...
LinearLayout linearLayoutView=（LinearLayout）root.findViewById（R.id.fragment\u ll\u home）；
linearLayoutView.addView（listView2,0）；
linearLayoutView.addView（listView，1）；
}

ListView不应共享布局参数。为每个ListView创建一个新的LayoutParams。非常感谢@cheticampListViews不应共享LayoutParams。为每个ListView创建一个新的LayoutParams。非常感谢@cheticamp
