Question

我使用yandex mapkit尝试获得准确的latlng但是它准确地绘制但是没有得到监听器失败我使用链接https://github.com/yandexmobile/yandexmapkit-android/blob/master/yandexmapkit-sample/src/ru/mapkittest/geocode/OverlayGeoCode.java但是监听器没有调用如何在每个点移动时获得监听器

谢谢， Shabeer Mohamed

如果您想在点击地图后对地图进行地理编码，则需要执行以下操作。

扩展Overlay类并实现GeoCodeListener

public class GeoCodeOverlay extends Overlay implements GeoCodeListener {

    public GeoCodeOverlay(MapController mapController) {
        super(mapController);
    }

    @Override
    public boolean onFinishGeoCode(final GeoCode geoCode) {
        if (geoCode != null) {
            getMapController().getMapView().post(new Runnable() {
                @Override
                public void run() {
                    // show display name of the point
                    Toast.makeText(getMapController().getContext(),
                            geoCode.getDisplayName(), Toast.LENGTH_LONG).show();
                }
            });
        }
        return true;
    }

    @Override
    public boolean onSingleTapUp(float x, float y) {
        getMapController().getDownloader()
                .getGeoCode(this, getMapController().getGeoPoint(new ScreenPoint(x, y)));
        return true;
    }
}

使用示例

public class GeoCoderActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_geo_coder);

        final MapView mapView = (MapView) findViewById(R.id.map);
        mapView.getMapController().getOverlayManager()
                .getMyLocation().setEnabled(true);
        mapView.getMapController().getOverlayManager()
                .addOverlay(new GeoCodeOverlay(mapView.getMapController()));

    }
}

activity_geo_coder.xml。不要忘记添加API密钥

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context="com.mapkittest.GeoCoderActivity">

    <ru.yandex.yandexmapkit.MapView
        android:id="@+id/map"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:apiKey="PLACE_YOUR_API_HERE"
        />

</RelativeLayout>
