GeoJsonLayer更改setOnFeatureClickListener

Question

您好我正在使用maps-utils实现Google Maps android。我添加了一个 GeoJsonLayer （LineString），现在我想在用户点击GeoJsonLayer的一个功能后更改功能样式（颜色和宽度）。到目前为止，我还没有找到任何与特征风格相关的属性。

road_layer=new GeoJsonLayer(mMap,R.raw.road_survey,this);
road_layer.setOnFeatureClickListener(new   Layer.OnFeatureClickListener() {
            @Override
            public void onFeatureClick(Feature feature) {

              //implement feature related operations 

            }
});

Answer 1

在阅读Google Maps Android GeoJSON Utility文档后，我设法实现了我的目标

road_layer=new GeoJsonLayer(mMap,R.raw.road_survey,this);
road_layer.setOnFeatureClickListener(new   Layer.OnFeatureClickListener() {
        @Override
        public void onFeatureClick(Feature feature) {
          GeoJsonLineStringStyle lineStringStyle = new GeoJsonLineStringStyle();
          lineStringFeature = (GeoJsonFeature) feature;
          lineStringStyle.setColor(Color.RED);
          lineStringStyle.setZIndex(10f);
          lineStringStyle.setWidth(2f);
          lineStringFeature.setLineStringStyle(lineStringStyle);

        }
});
