Android:CollapsingToolbarLayout中的MapView

标签: android android-mapview mapfragment android-collapsingtoolbarlayout

我目前正在尝试将Map View(或包含地图的片段)放在CollapsingToolbarLayout中。当RecyclerView滚动时我想要对它产生视差效果。不幸的是,它根本没有出现!甚至不是灰色网格!折叠动画虽然有效。我到处搜索,但我能找到的只是ImageView而没有其他组件。所以这是我的问题:

  1. 甚至可以在ImageView中添加CollapsingToolbarLayout之外的其他内容吗? (文档是在谈论儿童观点,所以我认为这是可能的)
  2. 如果是这样,是否允许片段?
  3. 然后我做错了什么?
  4.   

    这是我的xml:

    <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:map="http://schemas.android.com/tools"
        android:id="@+id/main_content"
        android:layout_width="match_parent"
        android:layout_height="match_parent">
    
        <android.support.design.widget.AppBarLayout
            android:id="@+id/appBarLayout"
            android:layout_width="match_parent"
            android:layout_height="300dp">
    
            <android.support.design.widget.CollapsingToolbarLayout
                android:id="@+id/collapsing_toolbar"
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                app:contentScrim="?attr/colorPrimary"
                app:expandedTitleMarginEnd="64dp"
                app:expandedTitleMarginStart="48dp"
                app:layout_scrollFlags="scroll|exitUntilCollapsed">
    
                <android.support.v7.widget.Toolbar
                    android:id="@+id/main_activity_toolbar"
                    android:layout_height="?attr/actionBarSize"
                    android:layout_width="match_parent"
                    android:background="?attr/colorPrimary"
                    android:layout_alignParentTop="true"
                    app:layout_collapseMode="pin"
                    app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
                </android.support.v7.widget.Toolbar>
    
                <com.google.android.gms.maps.MapView
                    android:id="@+id/main_activity_mapview"
                    android:layout_width="match_parent"
                    android:layout_height="match_parent"
                    android:apiKey="AIzaSyA-kEuKT39QK8eG7iYWriFgsvkrZZz6zNo"
                    android:clickable="true"
                    app:layout_collapseMode="parallax" />
    
            </android.support.design.widget.CollapsingToolbarLayout>
    
        </android.support.design.widget.AppBarLayout>
    
        <android.support.v7.widget.RecyclerView
            android:id="@+id/main_rv_list_places"
            android:scrollbars="vertical"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_behavior="@string/appbar_scrolling_view_behavior"/>
    
    </android.support.design.widget.CoordinatorLayout>
    
      

    我得到地图的部分。永远不会onMapReady   触发。

        if (mMap == null) {
    
            MapView mapView = (MapView) findViewById(R.id.mapview);
            mapView.getMapAsync(new OnMapReadyCallback() {
                @Override
                public void onMapReady(GoogleMap googleMap) {
                    mMap = googleMap;
                    MapsInitializer.initialize(MainActivity.this);
                    //...
                    // other stuff here
                }
            });
    
        }

You can use MapView also to display google map. 

在协调器布局中,我们可以使用折叠工具栏和mapview。工作正常。

需要正确提及谷歌地图密钥。

这对我来说很好用

使用片段而不是MapView

 <fragment xmlns:android="http://schemas.android.com/apk/res/android"
                  xmlns:map="http://schemas.android.com/apk/res-auto"
                  xmlns:tools="http://schemas.android.com/tools"
                  android:id="@+id/map"
                  android:name="com.google.android.gms.maps.SupportMapFragment"
                  android:layout_width="match_parent"
                  android:layout_height="match_parent"
                  tools:context="com.example.axel.googlemapsdemo.MapsActivity"/>

活动

    public class MapsActivity extends FragmentActivity implements OnMapReadyCallback {

        private GoogleMap mMap;
        RecyclerView mRecyclerView;
        TestAdapter adapter;

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_maps);
            // Obtain the SupportMapFragment and get notified when the map is ready to be used.
            SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
                    .findFragmentById(R.id.map);
            mapFragment.getMapAsync(this);
            setUpRecyclerView();
        }


        @Override
        public void onMapReady(GoogleMap googleMap) {
            mMap = googleMap;
   `        // Do stuff
        }
}

API密钥位于google_maps_api.xml。

我的父布局是CoordinatorLayout(我假设它也是你的,但它没有出现在问题上)

请注意,使用此方法,CollapsingToolbarLayout会滚动阴影地图滚动

解决方案:

AppBarLayout mAppBarLayout = (AppBarLayout)findViewById(R.id.appBarLayout);
        CoordinatorLayout.LayoutParams params = (CoordinatorLayout.LayoutParams) mAppBarLayout.getLayoutParams();
        AppBarLayout.Behavior behavior = new AppBarLayout.Behavior();
        behavior.setDragCallback(new AppBarLayout.Behavior.DragCallback() {
            @Override
            public boolean canDrag(AppBarLayout appBarLayout) {
                return false;
            }
        });
        params.setBehavior(behavior);
