如何从RecyclerView.ViewHolder
访问GoogleMap我有:
public class MapRowHolder extends RecyclerView.ViewHolder
{
public MapRowHolder(View view) {
super(view);
}
}
的xml:
<android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:android.support.v7.cardview="http://schemas.android.com/apk/res-auto"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android.support.v7.cardview:cardBackgroundColor="@color/blue"
android.support.v7.cardview:cardCornerRadius="@dimen/card_corner"
android.support.v7.cardview:cardElevation="@dimen/card_elevation">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_gravity="right|center_vertical"
android:gravity="center_vertical|right"
android:layout_width="fill_parent">
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="250dp"
android:tag="maps"
android:id="@+id/map_view_fragment" tools:context=".Map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_centerInParent="true"/>
</LinearLayout>
适配器:
public class MapAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder>
{
public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
RecyclerView.ViewHolder mh;
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.map_row, viewGroup, false);
mh = (RecyclerView.ViewHolder)new PodatkiZaMapRowHolder(v);
return mh;
}
public void onBindViewHolder(RecyclerView.ViewHolder RowHolder, int polozaj) {
MapRowHolder mapRowHolder = (MapRowHolder)RowHolder;
}
}
正确显示地图。它缩小到整个地球。并定位于中心的0,0。
如何获取地图片段(在ViewHolder中)?我想将相机移动到其他位置(我可以在获取GoogleMap对象后执行此操作)我应该如何以及在何处获取GoogleMap对象?
如果我使用MapView而不是map fragment它可以工作,但不会刷新地图。点击地图几次后,地图会刷新。 此致,Ales
