Android上的谷歌地图图标图像

时间：2015-04-13 21:30:04

标签： android image google-maps android-intent

我正在开发一个应用程序，显示谷歌地图和用户创建的一些标记。

此标记由外部数据库填充，并通过webservice进行连接。

我将来自此URL的MarkerOptions（）。中的url图像放入。此图像可以从所有标记中正确显示。但我对setOnInfoWindowClickListener也有一个意图，如果我显示这个图标图像，意图不起作用。如果我从图标图像中删除鳕鱼，意图正常工作。

有人可以帮助我吗？

代码

public void onResume() {
    super.onResume();

    dao = new LocalizacoesDAO(context);
    ArrayList<Localizacoes> lista = dao.buscarLocalizacoes();
    if (lista.size() > 1) {
        for (int i = 0; i < lista.size(); i++) {
            URL url = null;
            try {
                url = new URL(""+lista.get(i).getImagem()+"");
            } catch (MalformedURLException e) {
                e.printStackTrace();
            }
            Bitmap bmp = null;
            try {
                bmp = BitmapFactory.decodeStream(url.openConnection().getInputStream());
            } catch (IOException e) {
                e.printStackTrace();
            }
            Bitmap bmpok = Bitmap.createScaledBitmap(bmp, 30, 30, false);

            googlemap.addMarker(new MarkerOptions()
                        .title(lista.get(i).getNome() + " " + lista.get(i).getDescricao())
                        .snippet(String.valueOf(lista.get(i).getId()))
                        .position(lista.get(i).getLatLng())
                        .icon(BitmapDescriptorFactory.fromBitmap(bmpok)));

            }
        }
    }

 googlemap.setOnInfoWindowClickListener(new GoogleMap.OnInfoWindowClickListener() {
        @Override
        public void onInfoWindowClick(Marker marker) {


            Intent intent = new Intent(MainActivity.this,infoActivity.class);
            String title = marker.getTitle().toString();
            String snippet = marker.getSnippet();

            intent.putExtra("nome", title);
            intent.putExtra("id", snippet);
            startActivity(intent);


        }
    });
}

1 个答案:

答案 0 :(得分：0)

所以，错误说：

     Caused by: java.lang.NullPointerException
        at com.partytime.myapplication.infoActivity.onCreate(infoActivity.java:37)

所以它应该与infoActivity

相关

可能的原因之一是您传递的字符串为null，而infoActivity正在获取字符串并尝试访问该值。 

Intent intent = new Intent(MainActivity.this,infoActivity.class);
intent.putExtra("nome", title);
intent.putExtra("id", snippet);

如果这是原因，您可以检查infoActivity中的字符串。 

Intent intent= getIntent();
String title = intent.getExtra("nome");
String id = = intent.getExtra("id");

if (id == null || title == null) 
   // Exception
