android - Google Maps api V2 InfoWindowAdapter 有 textview 和 Imageview 事件!，如何处理这两个事件？

Question

您好，我正在开发带有自定义弹出窗口的谷歌地图演示应用程序。请建议我如何处理 TextView 和 ImageView 点击句柄。我无法获得 Activity 。下面是我的代码。

class PopupAdapter implements InfoWindowAdapter {
    LayoutInflater inflater=null;
        Context context;
        PopupAdapter(LayoutInflater inflater, Context context) {
            this.inflater=inflater;
            this.context = context;
        }

        public View getInfoWindow(Marker marker) {
            return(null);
        }

        public View getInfoContents(Marker marker) {

            MyModel mapItem = (MyModel) MainActivity.markers.get(marker.getId());  
            View popup=inflater.inflate(R.layout.popup, null);

            TextView tv=(TextView)popup.findViewById(R.id.title);
            ImageView im = (ImageView)popup.findViewById(R.id.icon);
            tv.setText(marker.getTitle());
            tv=(TextView)popup.findViewById(R.id.snippet);
            tv.setText(marker.getSnippet());


            im.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

        Log.e("POPUP", "Image Click");
        }
        });

            tv.setOnClickListener(new OnClickListener() {

         @Override
         public void onClick(View v) {

        Log.e("POPUP", "HI");
        Toast.makeText(context, "HI", Toast.LENGTH_SHORT).show();
    }
    });

    return(popup);
    }
}

主要 Activity

public class MainActivity extends AbstractMapActivity implements
OnNavigationListener, OnInfoWindowClickListener {
private static final String STATE_NAV="nav";
private static final int[] MAP_TYPE_NAMES= { R.string.normal,
    R.string.hybrid, R.string.satellite, R.string.terrain };

          (SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map);

      initListNav();

      map=mapFrag.getMap();

      map.setInfoWindowAdapter(new PopupAdapter(getLayoutInflater(),MainActivity.this));
      map.setOnInfoWindowClickListener(this);

    }
  }

  @Override

//    MyModel mapItem = (MyModel) markers.get(marker.getId()); 

//    Toast.makeText(this,marker.getSnippet()+ marker.getTitle() + " "+mapItem.getName() +" "+mapItem.getAdd() , Toast.LENGTH_LONG).show();
  }

  private void initListNav() {
    ArrayList<String> items=new ArrayList<String>();
    ArrayAdapter<String> nav=null;
    ActionBar bar=getSupportActionBar();

    for (int type : MAP_TYPE_NAMES) {
      items.add(getString(type));
    }

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.ICE_CREAM_SANDWICH) {

                                   android.R.layout.simple_spinner_item,

//    map.addMarker(new MarkerOptions().position(new LatLng(lat, lon)).title(getString(title)).snippet(getString(snippet)).icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));


  }
}

请建议我如何进行此 Activity 。谢谢..

Answer 1

您不能将 OnClickListeners 放在信息窗口的内容上。信息窗口本身不显示您的布局，而是显示从布局生成的 Bitmap。这包含在 the documentation 中:

As mentioned in the previous section on info windows, an info window is not a live View, rather the view is rendered as an image onto the map. As a result, any listeners you set on the view are disregarded and you cannot distinguish between click events on various parts of the view. You are advised not to place interactive components — such as buttons, checkboxes, or text inputs — within your custom info window.

您可以 use setOnInfoWindowClickListener()找出信息窗口本身何时被点击。
