【问题标题】:Android marker custom infowindowAndroid 标记自定义信息窗口
【发布时间】:2013-04-17 14:33:23
【问题描述】:

我正在使用谷歌地图 V2。

我需要在自定义InfoWindow 中显示ListView(带有图像的自定义ListView)。我试过了,只在View成功了,问题是我不能得到listItemClick事件。

googleMap.setInfoWindowAdapter(new InfoWindowAdapter() {

@Override
public View getInfoWindow(Marker arg0) {
    // TODO Auto-generated method stub
    return null;
}

@Override
public View getInfoContents(Marker arg0) {
    View v = getLayoutInflater().inflate(R.layout.infowindow, null);
    try{
        String[] names = {"The Mayfair (D22) Condominium, For Rent","The Mayfair (D22) Condominium, For Rent","The Mayfair (D22) Condominium, For Rent","The Mayfair (D22) Condominium, For Rent"};
        Log.d("f", names.toString());
        ArrayAdapter<String> adapter = new ArrayAdapter<String>(PropertyMapList.this, R.layout.info_row_view, R.id.textView1, names);
        Log.d("d", adapter.getCount()+"");
        ListView list = (ListView) v.findViewById(R.id.listView1);
        list.setAdapter(adapter);
        list.setOnItemClickListener(new OnItemClickListener() {

            @Override
            public void onItemClick(
                    AdapterView<?> arg0,
                    View arg1, int arg2,
                    long arg3) {
                Log.d("position:", arg2+"");
            }
        });
    }catch (Exception e) {
        e.printStackTrace();
    }
    return v;
}
});

    【解决方案1】:

    最后我自己通过这个代码集成得到了一个成功的答案。

    您可以在 Play 商店中找到该应用

    https://play.google.com/store/apps/details?id=com.stp.stproperty&hl=en

    标记 XML 文件

    <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="300dp"
        android:layout_height="wrap_content"
        android:orientation="vertical" android:background="@drawable/marker_bg" >
    
        <ListView
            android:id="@+id/listView1"
            android:layout_width="300dp"
            android:layout_height="wrap_content"
            android:layout_marginTop="7dp"
            android:layout_marginLeft="5dp"
            android:layout_marginBottom="20dp"
            android:layout_marginRight="5dp" >
    
        </ListView>
    
    </RelativeLayout>
    

    和listview自定义布局(带箭头图片的文字)

    <?xml version="1.0" encoding="utf-8"?>
    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="90dp"
        android:orientation="vertical"
        android:gravity="center_vertical"
        android:background="@drawable/marker_selecter" >
    
        <RelativeLayout android:layout_width="fill_parent"
            android:layout_height="wrap_content">
    
            <TextView
                android:id="@+id/ProeprtyName"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentLeft="true"
                android:layout_centerHorizontal="true"
                android:layout_marginLeft="5dp"
                android:layout_toLeftOf="@+id/RightArrow"
                android:textColor="@color/list_textcolor"
                android:textSize="16sp" />
    
            <ImageView
                android:id="@+id/RightArrow"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentRight="true"
                android:layout_marginRight="3dp"
                android:layout_centerInParent="true"
                android:src="@drawable/detaildisclosure" />
        </RelativeLayout>
    </RelativeLayout>
    

    为地图添加标记

    // Set title for marker here, with the help of this title we can customize easily and change lat and long values, icon as weel to your code
    googleMap.addMarker(new MarkerOptions()
        .title(infoTitle.get(index))
        .position(new LatLng(Double.parseDouble(lanAndLat.get(index).split("\\$")[0]), Double.parseDouble(lanAndLat.get(index).split("\\$")[1])))
        .icon(BitmapDescriptorFactory.fromBitmap(icon)));
    

    将标记 onclicklistener 设置为:

    googleMap.setOnMarkerClickListener(new OnMarkerClickListener() {
    
        @Override
        public boolean onMarkerClick(Marker arg0) {
    
            drawCustomMarker(arg0.getPosition().latitude, arg0.getPosition().longitude, arg0.getTitle(),0);
            return true;
        }
    });
    

    将自定义标记声明为全局变量(从视图中清除并重新创建它会有所帮助)

    CustomMarker = getLayoutInflater().inflate(R.layout.infowindow, null);
    

    自定义标记绘图功能。我为我的用例做了它。请根据您的要求进行定制

    private void drawCustomMarker(Double latitude, Double longitude, String title, int propertyId){
        try{
            int selectedMarkerIndex = -1; // On-select from list-view this needs to be highlighted in marker as selected
            mapinnerLayout.removeView(CustomMarker);
            googleMap.animateCamera(CameraUpdateFactory.newLatLng(new LatLng(latitude, longitude)));
    
            // I am passing title as string with # separated values to access
    
            String[] names = title.split("\\#");
            ArrayList<MarkerAdapterClass> markerClass = new ArrayList<MarkerAdapterClass>();
            for(int i=0;i<names.length;i++){
                // this is custom class for my own use if you want you can change this class 
                MarkerAdapterClass classObj = new MarkerAdapterClass();
                String[] data = names[i].split("\\|");
                int pId = Integer.parseInt(data[1]);
                if(pId==propertyId){
                    selectedMarkerIndex = i;
                }
                classObj.setpropertyTitle(data[0]);
                classObj.setid(pId);
                classObj.setitemIndex(Integer.parseInt(data[2]));
                markerClass.add(classObj);
            }
            CustomMarker.setVisibility(View.VISIBLE);
            MarkerInfoAdapter adapter = new MarkerInfoAdapter(PropertyMapList.this, markerClass, districtView);
            final ListView list = (ListView) CustomMarker.findViewById(R.id.listView1);
            list.setAdapter(adapter);
            if(selectedMarkerIndex>=0){
                adapter.setSelected(selectedMarkerIndex);
                list.setSelection(selectedMarkerIndex);
            }
            int height = getMarkerInfoHeight(markerClass.size(), list);
            RelativeLayout.LayoutParams layoutParams = new RelativeLayout.LayoutParams(450,height);
            layoutParams.addRule(RelativeLayout.ALIGN_PARENT_TOP);
            layoutParams.addRule(RelativeLayout.CENTER_HORIZONTAL);
            layoutParams.setMargins(0, mapinnerLayout.getHeight()/2 - (height+30), 0, 0);
            mapinnerLayout.addView(CustomMarker, layoutParams);
    
        }catch(Exception e){
            //e.printStackTrace();
        }
    }
    

    mapinnerLayout 是相对布局(地图的容器)

    我正在使用它来支持 10 和 7 英寸平板电脑。设备和纵向到横向的高度和宽度会有所不同。我在这里计算:

    public int getMarkerInfoHeight(int size, ListView view){
        int height = 90;
        int Orientation = PropertyMapList.this.getResources().getConfiguration().orientation;
        DisplayMetrics displaymetrics = new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
        int deviceheight = displaymetrics.heightPixels;
        RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT);
        lp.setMargins(5, 3, 5, 12);
        if(Orientation == Configuration.ORIENTATION_LANDSCAPE && deviceheight <= 700){
            if(size > 1){
                height = 190;
                lp.setMargins(5, 3, 5, 25);
            }
        }else{
            if(size == 2){
                height = 190;
                lp.setMargins(5, 3, 5, 25);
            }else if(size > 2){
                height = 285;
                lp.setMargins(5, 3, 5, 35);
            }
        }
        view.setLayoutParams(lp);
        return height;
    }
    

    标记适配器:

    public class MarkerInfoAdapter extends BaseAdapter {
        private static ArrayList<MarkerAdapterClass> propertyNames;
        private LayoutInflater mInflater;
        int selectedPosition = -1;
        private ListView parentAdapter;
        Context context;
        public MarkerInfoAdapter(Context context, ArrayList<MarkerAdapterClass> results, ListView parentAdapter) {
            propertyNames = results;
            this.parentAdapter = parentAdapter;
            mInflater = LayoutInflater.from(context);
            this.context = context;
        }
        @Override
        public int getCount() {
            return propertyNames.size();
        }
    
        @Override
        public Object getItem(int position) {
            return propertyNames.get(position);
        }
    
        @Override
        public long getItemId(int position) {
            return position;
        }
        static class ViewHolder {
            TextView Name;
            ImageView image;
        }
        @Override
        public View getView(final int position, View convertView, ViewGroup parent) {
            ViewHolder holder;
            try{
                if(convertView==null)
                {
                    convertView=mInflater.inflate(R.layout.marker_row_view, null);
                    holder=new ViewHolder();
                    holder.Name=(TextView)convertView.findViewById(R.id.ProeprtyName);
                    holder.image=(ImageView)convertView.findViewById(R.id.RightArrow);
                    convertView.setTag(holder);
                }
                else
                {
                    holder=(ViewHolder)convertView.getTag();
                }
                holder.Name.setText(propertyNames.get(position).getpropertyTitle());
                if(selectedPosition == position){
                    convertView.setBackgroundResource(R.drawable.blue_marker_bg);
                    ((TextView)convertView.findViewById(R.id.ProeprtyName)).setTextColor(Color.WHITE);
                    convertView.setMinimumHeight(80);
                }else{
                    convertView.setBackgroundResource(R.drawable.directories_list_bg);
                    ((TextView)convertView.findViewById(R.id.ProeprtyName)).setTextColor(Color.BLACK);
                    convertView.setMinimumHeight(80);
                }
                ((TextView)convertView.findViewById(R.id.ProeprtyName)).setOnClickListener(new OnClickListener() {
    
                    @Override
                    public void onClick(View v) {
                        setSelected(position);
                        if(context.getClass().getSimpleName().equals("PropertyMapList")){
                            ((PropertyListAdaptor)parentAdapter.getAdapter()).setSelected(propertyNames.get(position).getitemIndex());
                        }else{
                            ((FavoriteListAdapter)parentAdapter.getAdapter()).setSelected(propertyNames.get(position).getitemIndex());
                        }
                        parentAdapter.setSelection(propertyNames.get(position).getitemIndex());
                    }
                });
            }catch (Exception e) {
                e.printStackTrace();
            }
    
            return convertView;
        }
        public void setSelected(int position) {
            selectedPosition = position;
            notifyDataSetChanged();
        }
    }
    

    标记适配器类

    public class MarkerAdapterClass {
        private int id;
        private String propertyTitle;
        private int itemIndex=0;
    
        public String getpropertyTitle() {
            return propertyTitle;
        }
        public void setpropertyTitle(String title) {
            this.propertyTitle = title;
        }
        public int getitemIndex() {
            return itemIndex;
        }
        public void setitemIndex(int itemIndex) {
            this.itemIndex = itemIndex;
        }
        public int getid() {
            return this.id;
        }
        public void setid(int id) {
            this.id = id;
        }
    }

      【解决方案2】:

      绘制的信息窗口不是实时视图。视图在返回时呈现为图像(使用View.draw(Canvas)

      检查documentation

      • s,看过这个文档,但我需要像我在这里尝试的那样完成它。有可能吗?
      • @SampathKumar 这是不可能的。您可以改为在标记单击时显示对话框。
