Question

我的问题是在带有协调器布局设计的ExpandableListView中滚动。工具栏可以正常工作，并且在触摸时可以隐藏，但ExpandableListView不会滚动

我需要使用NestedScrollView，因为layout_navigation_view在任何地方都是通用的。

看看

我的主要Java代码和XML的设计代码是：

ActivityMain.java

public class ActivityMain   extends ActivityNavigationView {

           ArrayList<StructNote> group ; //StructNote public String id,title,icon; // StructNote = Filde Parametr
           ArrayList<ArrayList<StructNote>> child ;

           ActivityAdapter mAdapter; // class extends BaseExpandableListAdapter 

           ExpandableListView exListView ;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // ---> content_frame =>  layout_navigation_view.xml
        FrameLayout contentFrameLayout = (FrameLayout) findViewById(R.id.content_frame); 
        getLayoutInflater().inflate(R.layout.activity_main, contentFrameLayout);

        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        navigationView.getMenu().getItem(1).setChecked(true);

        exListView = (ExpandableListView) findViewById(R.id.exListView);

        //... Fill Group Child Adapter List
        //...Other CODE ...
    }
 }

ActivityNavigationView.java

public class ActivityNavigationView extends AppCompatActivity {

    DrawerLayout drawerLayout;
    ActionBarDrawerToggle actionBarDrawerToggle;
    Toolbar toolbar;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.layout_navigation_view);
        NavigationView navigationView = (NavigationView) findViewById(R.id.nav_view);
        //...Other CODE ... Click menu and Open close NavigationView, Toolbar
    }
 }

Answer 1

工具栏可以正常工作，并且在触摸时可以隐藏，但是flowchart 不滚动

是的，是因为ExpandableListView并使用了 SwipeRefreshLayout inside of NestedScrollView 。

添加SwipeRefreshLayout小部件要添加滑动以刷新小部件，现有应用程序，将SwipeRefreshLayout 添加为单个应用程序的父项 ListView或GridView

解决方案：

首先将SwipeRefreshLayout放在SwipeRefreshLayout中的NestedScrollView之外：

layout_navigation_view.xml

然后删除<android.support.v4.widget.SwipeRefreshLayout android:id="@+id/swipeToRefresh" android:layout_width="match_parent" android:layout_height="match_parent" app:layout_behavior="@string/appbar_scrolling_view_behavior"> <android.support.v4.widget.NestedScrollView android:layout_width="match_parent" android:layout_height="match_parent" android:fillViewport="true"> ... </android.support.v4.widget.NestedScrollView> </android.support.v4.widget.SwipeRefreshLayout>中的SwipeRefreshLayout。

在具有协调器布局的ExpandableListView中滚动
