kml文件android编程

我在android studio上使用google maps api试图在我的地图中显示一个kml文件。

在我的Kml上，每个多边形都有像这样的儿子值

<ExtendedData><SchemaData schemaUrl="#Zonas_VDP21_Marzo_18">
    <SimpleData name="Ciudad">SAN ANTONIO CORONADO</SimpleData>
    <SimpleData name="Agente">VDP21</SimpleData>
    <SimpleData name="ZIP">NORESTE</SimpleData>
    <SimpleData name="PROVINCIA">1</SimpleData>
    <SimpleData name="GerenciaGe">CMD3</SimpleData>
    <SimpleData name="ID Bolsa_1">CI277</SimpleData>
    <SimpleData name="DTA Distri">11104</SimpleData>
</SchemaData></ExtendedData>

我要做的是在点击它之后让每个多边形显示它的数据。像谷歌地图在线做（https://www.google.com/maps/d/u/0）。

Google Maps Example

但我可以像这样显示kml图层：

Android Map

这没关系，但我无法点击任何多边形来访问其信息这是我的代码

public void DownloadFiles(){

    try {
        URL u = new URL("http://XXX.XXX.XXX.XXX:XXXX/XXXXXX/XXXXXX/XXXX.kml");
        final InputStream is = u.openStream();
        layer = new KmlLayer(map, is, getApplicationContext());
        runOnUiThread(new Runnable() {
            @Override
            public void run() {
                try {


                    layer.addLayerToMap();
                    layer.setOnFeatureClickListener(new KmlLayer.OnFeatureClickListener() {
                        @Override
                        public void onFeatureClick(com.google.maps.android.data.Feature feature) {
                            Toast.makeText(MapsActivity.this,
                                    "Feature clicked: " + feature.getId(),
                                    Toast.LENGTH_SHORT).show();
                        }
                    });

                } catch (IOException e) {
                    e.printStackTrace();
                } catch (XmlPullParserException e) {
                    e.printStackTrace();
                } catch (Exception ex){
                    ex.getMessage();
                }
            }
        });


    } catch (MalformedURLException mue) {
        Log.e("SYNC getUpdate", "malformed url error", mue);
    } catch (IOException ioe) {
        Log.e("SYNC getUpdate", "io error", ioe);
    } catch (SecurityException se) {
        Log.e("SYNC getUpdate", "security error", se);
    } catch (XmlPullParserException e) {
        e.printStackTrace();
    }
}

记住这一点： 1.地图正确加载并在我的应用上创建。 2.我的网络服务正确下载了kml文件。 3. kml文件格式是正确的。

在KML中，您可以将共享气球模板应用于所有要素（地标，点，线，多边形等）。你可以使用共享的BalloonStyle来实现这个目标。用于所需气球布局的CSS，以及用于拉入当前要素数据的变量（例如：$ [my_variable]）。请参阅下面示例KML中<BalloonStyle>标记的内容，该标记使用您提供的示例数据。

我不确定在Android上使用它是否能完全解决您的问题，但这就是您在KML中执行此操作的方式，以便在Google地球和地图中查看。
