Question

您好我正在使用自定义弹出窗口进行谷歌地图的演示应用程序。请建议我如何处理textview＆amp;图像视图单击手柄。我无法得到活动。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);
    }
}

请建议我如何做这个活动。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

如上一节关于信息窗口所述，信息窗口不是实时视图，而是视图在地图上呈现为图像。因此，您在视图上设置的任何侦听器都将被忽略，并且您无法区分视图各个部分上的单击事件。建议您不要在自定义信息窗口中放置交互式组件（如按钮，复选框或文本输入）。

您可以use setOnInfoWindowClickListener()找出点按信息窗口的时间。

Answer 2

是的，你不能在信息窗口的视图上添加监听器。你可以做的一件事，onInfoWindowClick显示警报菜单，并为用户提供一些选项。

mMap.setOnInfoWindowClickListener(new OnInfoWindowClickListener() {

        @Override
        public void onInfoWindowClick(Marker arg0) {
            final CharSequence[] items = { "message", "call"};

    AlertDialog.Builder builder = new AlertDialog.Builder(this);
    builder.setTitle("Call");
    builder.setItems(items, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int item) {
            if (item == 0) {
                sendMessage();
            } else {
                makeCall();

            }

        }
    });
    AlertDialog alert = builder.create();
    alert.show();
        }
    });

或者你可以试试这样的东西.. 我不确定它是否有效。 https://stackoverflow.com/a/15040761/1792228

Answer 3

正如其他答案中所解释的那样，Google Maps Android API v2不直接支持您想要实现的目标，但是......

您可以将自己置于MapFragment或MapView前面，处理MotionEvents以使OnClickListener被调用。
