使用协调器布局在 ExpandableListView 中滚动

Question

我的问题是使用协调器布局设计在 ExpandableListView 中滚动。 工具栏工作正常，当它触摸时，它会隐藏，但 ExpandableListView 不滚动

我需要使用 NestedScrollView，因为 layout_navigation_view 无处不在。

看看

我使用 Java 的主要代码和我使用 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
    }
 }

            <ExpandableListView

                android:layout_width="match_parent"
                android:layout_height="match_parent"
                android:transcriptMode="disabled"
                android:divider="@null"
                android:dividerHeight="0dp"

            </ExpandableListView>

</LinearLayout>

Answer 1

工具栏工作正常，当它被触摸时，它会被隐藏，但ExpandableListView 不滚动

是的，这是因为 SwipeRefreshLayout 和使用 SwipeRefreshLayout inside of NestedScrollView。

添加 SwipeRefreshLayout 小部件 将滑动刷新小部件添加到 一个现有的应用程序，添加SwipeRefreshLayout 作为单个应用程序的父级 ListView 或 GridView

解决方案：

首先将SwipeRefreshLayout 放在NestedScrollView 之外的layout_navigation_view.xml 中：

<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>

并删除activity_main.xml 中的SwipeRefreshLayout。
