【问题描述】：
我正在使用一个 android 应用程序。用户在谷歌地图上搜索餐馆。在谷歌地图上显示他所有邻居餐厅的标记。如果他点击一个标记，它会显示一个自定义信息窗口。我的问题是我无法加载从 Google 地方返回的图像。我得到了正确的图像网址，但我无法在窗口中显示它。
信息窗口
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="vertical"
android:background="@color/bg_color" >
<ImageView
android:id="@+id/place_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="false"" />
<TextView
android:id="@+id/place_title"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/place_vicinity"
android:layout_width="wrap_content"
android:layout_height="wrap_content" />
<LinearLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:background="@color/bg_color" >
<RatingBar
android:id="@+id/place_rating"
style="?android:attr/ratingBarStyleSmall"
android:numStars="5"
android:rating="0"
android:isIndicator="false"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginLeft="5dip" />
<ImageView
android:id="@+id/navigate_icon"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:focusable="false"
android:src="@drawable/navigate" />
</LinearLayout>
在创建时我有这个
mGoogleMap.setInfoWindowAdapter(new InfoWindowAdapter() {
// Use default InfoWindow frame
@Override
public View getInfoWindow(Marker arg0) {
return null;
}
// Defines the contents of the InfoWindow
@Override
public View getInfoContents(Marker arg0) {
// Getting view from the layout file info_window_layout
View v = getLayoutInflater().inflate(R.layout.info_window_layout, null);
// Getting the snippet from the marker
String snippet = arg0.getSnippet();
// Getting the snippet from the marker
String titlestr = arg0.getTitle();
String cutchar1= "%#";
String cutchar2= "%##";
String ratingstr = snippet.substring(0,snippet.indexOf( cutchar1 ));
String vicinitystr = snippet.substring(snippet.indexOf( cutchar1 )+2, snippet.indexOf( cutchar2 ) );
String iconurl= snippet.substring(snippet.indexOf( cutchar2 )+3);
// Getting reference to the TextView to set latitude
TextView title = (TextView) v.findViewById(R.id.place_title);
TextView vicinity = (TextView) v.findViewById(R.id.place_vicinity);
ImageView image = (ImageView) v.findViewById(R.id.navigate_icon);
// Setting the latitude
title.setText(titlestr);
// declare RatingBar object
RatingBar rating=(RatingBar) v.findViewById(R.id.place_rating);// create RatingBar object
if( !(ratingstr.equals("null")) ){
rating.setRating(Float.parseFloat(ratingstr));
}
vicinity.setText(vicinitystr);
final DownloadImageTask download = new DownloadImageTask((ImageView) v.findViewById(R.id.place_icon) ,arg0);
download.execute(iconurl);
// Returning the view containing InfoWindow contents
return v;
}
});
DownloadImage 代码是：
private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
ImageView bmImage;
Marker marker;
boolean refresh;
public DownloadImageTask(final ImageView bmImage, final Marker marker) {
this.bmImage = bmImage;
this.marker=marker;
this.refresh=false;
}
public void SetRefresh(boolean refresh ){
this.refresh=true;
}
/* @Override
protected void onPreExecute()
{
super.onPreExecute();
bmImage.setImageBitmap(null);
}*/
@Override
protected Bitmap doInBackground(String... urls) {
String urldisplay = urls[0];
Bitmap mIcon11 = null;
try {
InputStream in = new java.net.URL(urldisplay).openStream();
mIcon11 = BitmapFactory.decodeStream(in);
} catch (Exception e) {
Log.e("Error", e.getMessage());
e.printStackTrace();
}
return mIcon11;
}
@Override
protected void onPostExecute(Bitmap result) {
if(!refresh){
SetRefresh(refresh);
bmImage.setImageBitmap(result);
marker.showInfoWindow();
}
}
}
最后，当我执行代码并点击标记时，getInfoContents 不会停止执行并且图标不会出现。
为什么会这样？
