你好我正在使用谷歌地图android api,我正在使用谷歌地图android geojson实用程序。我在地图中添加了3层geojson,只有 road_layer (LineString)具有功能点击事件。点击事件正常工作,直到我添加 samsad_boundary_layer (多边形)。问题是如果点击了 samsad_boundary_layer 功能,它会触发 road_layer 功能点击事件,尽管图层(samsad_boundary_layer)没有功能点击事件。

private void showBoundery(){
    try {
        samsad_boundary_layer=new GeoJsonLayer(mMap,R.raw.samsad_boundary,MapActivity.this); //1st Layer
    } catch (IOException e) {
        e.printStackTrace();
    } catch (JSONException e) {
        e.printStackTrace();
    }
    samsad_boundary_layer.getDefaultPolygonStyle().setZIndex(-12f);
    GeoJsonPolygonStyle polygonStyle=samsad_boundary_layer.getDefaultPolygonStyle();
    polygonStyle.setStrokeWidth(5f);
    polygonStyle.setStrokeColor(getResources().getColor(R.color.purple));
    samsad_boundary_layer.addLayerToMap();
}

private void retrieveFileFromResource() {
    try {
        temp_layer=new GeoJsonLayer(mMap,R.raw.area_survey,this); //2nd Layer
        temp_layer.addLayerToMap();
        road_layer=new GeoJsonLayer(mMap,R.raw.road_survey,this); //3rd Layer
        road_layer.setOnFeatureClickListener(new Layer.OnFeatureClickListener() {
            @Override
            public void onFeatureClick(Feature feature) {
                if (feature!=null){
                    Iterator<HashMap> flavoursIter = feature.getProperties().iterator();
                   while (flavoursIter.hasNext()){
                        Map.Entry entry = (Map.Entry)flavoursIter.next();
                        //Log.v("SURVEYOR_FEATURE",entry.getKey().toString()+":"+entry.getValue());

                    }

                }
            }
        });
        GeoJsonLineStringStyle lineStyle=road_layer.getDefaultLineStringStyle();
        lineStyle.setZIndex(10f);
        lineStyle.setWidth(2f);
        lineStyle.setColor(getResources().getColor(R.color.light_green));
        road_layer.addLayerToMap();
    } catch (IOException e) {
        e.printStackTrace();
    } catch (JSONException e) {
        e.printStackTrace();
    }
}

与其在地图上分别添加3层,而是遍历所有层并创建单层。 然后添加图层以映射并设置功能单击侦听器。相应地处理onFeatureClick。
