通过网址在Google Maps v2 Android上设置标记图标 [英] Set marker icon on Google Maps v2 Android from URL

问题描述

我无法将Google Places API提供的图标添加到标记中.例如，我想让图标从Google Places API的JSON返回:

"icon" : "http://maps.gstatic.com/mapfiles/place_api/icons/generic_business-71.png"

这是我现在不添加图标的方式:

for (Place place : mNearPlaces.results) {
     LatLng placeLatLng = new LatLng(place.geometry.location.lat,
         map.addMarker(new MarkerOptions()
             .position(placeLatLng)
             .title(place.name));
}

我查看了这篇文章和建议使用一些AsyncTask来下载图像.还有其他方法可以做到这一点(这种方法似乎很慢)?是否有设置Google Places API提供的标记图像的标准方法?

这是用于标记的Google Maps Android API v2文档

谢谢

解决方案

您好，可以使用库来帮助您从URL查看图像.访问 https://github.com/nostra13/Android-Universal-Image-Loader适用于 Android通用图像加载器

您也可以访问了解有关下载图像的信息

http://brainflush .wordpress.com/2009/11/23/droid-fu-part-2-webimageview-and-webgalleryadapter/

然后是

对于自定义标记图标"，您可以使用图标来显示为标记.从任何受支持的来源中加载图标.

fromAsset(String assetName)–从资产文件夹加载

fromBitmap(位图图像​​)–加载位图图像

fromFile(字符串路径)–从文件加载

fromResource(int resourceId)–从可绘制资源加载

尝试如下

// latitude and longitude
double latitude = 17.385044;
double longitude = 78.486671;

// create marker
MarkerOptions marker = new MarkerOptions().position(new LatLng(latitude, longitude)).title("Hello Maps");

// Changing marker icon
// set yours icon here
marker.icon(BitmapDescriptorFactory.fromResource(R.drawable.my_marker_icon)));

// adding marker
googleMap.addMarker(marker);

I am unable to add the icon provided by the Google Places API to the marker. For example, I would like to have the icon returned from the JSON of Google Places API:

"icon" : "http://maps.gstatic.com/mapfiles/place_api/icons/generic_business-71.png"

Here's how I am doing it now without adding the icon:

for (Place place : mNearPlaces.results) {
     LatLng placeLatLng = new LatLng(place.geometry.location.lat,
         map.addMarker(new MarkerOptions()
             .position(placeLatLng)
             .title(place.name));
}

I looked at this post and the answer suggested using some AsyncTask to download the image. Is there any other way to do this (that way seems slow)? Is there a standard way of setting the marker image provided by the Google Places API?

Here is the Google Maps Android API v2 Documentation for Markers

Thanks

Hi use a librariy that help you to view images from URL. visit https://github.com/nostra13/Android-Universal-Image-Loader for Android-Universal-Image-Loader

also you can visit to know for downloading the image

http://brainflush.wordpress.com/2009/11/23/droid-fu-part-2-webimageview-and-webgalleryadapter/

and after that

for the Custom Marker Icon, you can use an icon to show as a marker. load the icon from any kind of supported sources.

fromAsset(String assetName) – Loading from assets folder

fromBitmap (Bitmap image) – Loading bitmap image

fromFile (String path) – Loading from file

fromResource (int resourceId) – Loading from drawable resource

try as follows

// latitude and longitude
double latitude = 17.385044;
double longitude = 78.486671;

// create marker
MarkerOptions marker = new MarkerOptions().position(new LatLng(latitude, longitude)).title("Hello Maps");

// Changing marker icon
// set yours icon here
marker.icon(BitmapDescriptorFactory.fromResource(R.drawable.my_marker_icon)));

// adding marker
googleMap.addMarker(marker);
