Java listview中的Mapview（litemode）仅显示一个地图

使用此代码，仅显示第二项的映射。 所有地图都有谷歌标志（左下角）和在谷歌地图中打开地图的按钮（右下角），但其余的都是空白。 在向下滚动和向上滚动后，该图标也会消失

现在所有的地图都加载了相同的地址，但这显然会改变

我的另一个选择是使用静态贴图，但我想知道litemode mapview是否可以工作

CustomGrid.java

public class CustomGrid extends BaseAdapter{
    private Context mContext;
    Bundle savedInstanceState;

    private GoogleMap map;

    private final String[] eventname;

    String finaldate;

    static final LatLng HAMBURG = new LatLng(53.558, 9.927);



    //private final int[] Imageid;

    //public CustomGrid(Context c,String[] web,int[] Imageid ) {
    public CustomGrid(Context c, final Bundle b, String[] eventname, String[] date, String[] venue, String[] city, String[] state, String[] catA, String[] catB, String[] pricerange, Double[] price) {
        mContext = c;
        //this.Imageid = Imageid;
        this.eventname = eventname;
        this.savedInstanceState = b;
    }

    @Override
    public int getCount() {
        // TODO Auto-generated method stub
        return eventname.length;
    }

    @Override
    public Object getItem(int position) {
        // TODO Auto-generated method stub
        return null;
    }

    @Override
    public long getItemId(int position) {
        // TODO Auto-generated method stub
        return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        View grid;
        LayoutInflater inflater = (LayoutInflater) mContext
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        if (convertView == null) {

            grid = new View(mContext);
            //grid = inflater.inflate(R.layout.grid_single, null);
            //grid = inflater.inflate(R.layout.grid_single, parent, false);
            grid = inflater.inflate(R.layout.grid_single, parent, false);

        } else {
            grid = (View) convertView;
        }

        /*
        TextView textView_eventname = (TextView) grid.findViewById(R.id.grid_text_eventname);
        TextView textView_location = (TextView) grid.findViewById(R.id.grid_text_location);
        TextView textView_pricerange = (TextView) grid.findViewById(R.id.grid_text_pricerange);
        */

        TextView textView_eventname = (TextView) grid.findViewById(R.id.event_name);

        textView_eventname.setText(eventname[position]);

        MapView mapView = (MapView) grid.findViewById(R.id.event_map);
        mapView.onCreate(savedInstanceState);

        map = mapView.getMap();

        MapsInitializer.initialize(mContext);


        map.addMarker(new MarkerOptions()
                .position(HAMBURG)
                .title("Me")
                .icon(BitmapDescriptorFactory.fromResource(R.mipmap.ic_launcher)));

        map.moveCamera(CameraUpdateFactory.newLatLngZoom(HAMBURG, 15));

        return grid;
    }


}

调用自定义网格以创建平铺的函数

public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.event_grid);

        CustomGrid adapter = new CustomGrid(EventGrid.this, savedInstanceState, eventname);
        grid=(GridView)findViewById(R.id.grid);
        grid.setAdapter(adapter);    
    }

grid\u single.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:map="http://schemas.android.com/apk/res-auto"
    android:orientation="vertical" android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:id="@+id/event_name"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="#3E3E3E"
        android:textStyle="bold" />


    <com.google.android.gms.maps.MapView
        android:id="@+id/event_map"
        android:layout_width="wrap_content"
        android:layout_height="120dp"
        android:background="#3E3E3E"
        android:textStyle="bold"
        map:cameraZoom="13"
        map:mapType="normal"
        map:liteMode="true"/>

</LinearLayout>

谢谢。

我想你说的是这种情况。您是否正确添加了API密钥

仅当您单击标记时，方向和地图徽标才会显示
