我目前正在尝试放置一个Map View
(或包含地图的片段)内CollapsingToolbarLayout
。我想在它上有视差效果RecyclerView
卷轴。不幸的是,它根本没有出现!连灰色网格都没有!不过,折叠动画正在发挥作用。我到处寻找,但我所能找到的只是ImageView
并且没有其他组件。这是我的问题:
- 是否可以放置除
ImageView
in a CollapsingToolbarLayout
? (文档正在谈论子视图,所以我认为这是可能的)
- 如果是这样,是否也允许使用片段?
- 那我做错了什么??
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>
还有我拿回地图的部分。onMapReady
从来没有
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 Coordinator 布局中,我们可以使用带有 mapview 的折叠工具栏。它工作正常。
需要正确提及谷歌地图键。
