Answer 1

制作自定义的 Listview 并在元素的自定义布局中添加所有 3 个项目，假设您不想显示某个特定元素中的所有项目，然后使用属性使其不可见 visibility

Answer 2

首先我改变了布局。所以，最后，我在 1 个布局中放置了 3 个 ListView。<android.support.v4.widget.SwipeRefreshLayout&nbsp; &nbsp; android:id="@+id/swipe"&nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; android:layout_height="wrap_content">&nbsp; &nbsp; <android.support.v4.widget.NestedScrollView&nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; android:fillViewport="true">&nbsp; &nbsp; &nbsp; &nbsp; <LinearLayout&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:orientation="vertical"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:padding="10dp">&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <ListView&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:id="@+id/listviewResponse"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:divider="@android:color/transparent"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:dividerHeight="10sp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:paddingStart="15dp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:paddingEnd="15dp" />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <ListView&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:id="@+id/listviewDirect"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:divider="@android:color/transparent"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:dividerHeight="10sp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:paddingStart="15dp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:paddingEnd="15dp" />&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; <ListView&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:id="@+id/listviewOpen"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_width="match_parent"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:layout_height="wrap_content"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:divider="@android:color/transparent"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:dividerHeight="10sp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:paddingStart="15dp"&nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; &nbsp; android:paddingEnd="15dp" />&nbsp; &nbsp; &nbsp; &nbsp; </LinearLayout>&nbsp; &nbsp; </android.support.v4.widget.NestedScrollView></android.support.v4.widget.SwipeRefreshLayout>我创建了 3 个不同的适配器并将适配器设置为 Listviews&nbsp; &nbsp; &nbsp; &nbsp; @BindView(R.id.listviewResponse)&nbsp; &nbsp; &nbsp; &nbsp; ListView listViewResponse;&nbsp; &nbsp; &nbsp; &nbsp; @BindView(R.id.listviewOpen)&nbsp; &nbsp; &nbsp; &nbsp; ListView listViewOpen;&nbsp; &nbsp; &nbsp; &nbsp; @BindView(R.id.listviewDirect)&nbsp; &nbsp; &nbsp; &nbsp; ListView listViewDirect;&nbsp; &nbsp; &nbsp; &nbsp; private List<Response> responses = new ArrayList<>();&nbsp; &nbsp; &nbsp; &nbsp; private List<OpenOrder> open_orders = new ArrayList<>();&nbsp; &nbsp; &nbsp; &nbsp; private List<DirectOrder> direct_orders = new ArrayList<>();&nbsp; &nbsp; &nbsp; &nbsp; RequestListResponseAdapter adapterResponse;&nbsp; &nbsp; &nbsp; &nbsp; RequestListOpenAdapter adapterOpen;&nbsp; &nbsp; &nbsp; &nbsp; RequestListDirectAdapter adapterDirect;&nbsp; &nbsp; &nbsp; &nbsp; adapterResponse = new RequestListResponseAdapter(getContext(), responses);&nbsp; &nbsp; &nbsp; &nbsp; adapterOpen = new RequestListOpenAdapter(getContext(), open_orders, openType);&nbsp; &nbsp; &nbsp; &nbsp; adapterDirect = new RequestListDirectAdapter(getContext(), direct_orders);&nbsp; &nbsp; &nbsp; &nbsp; listViewResponse.setAdapter(adapterResponse);&nbsp; &nbsp; &nbsp; &nbsp; listViewDirect.setAdapter(adapterDirect);&nbsp; &nbsp; &nbsp; &nbsp; listViewOpen.setAdapter(adapterOpen);
