我的ArcGIS Feature Server中有3层(Drainage,Bridge和Slope)。我的Android应用查看ArcGISmap
上的每个图层,并根据复选框勾选设置图层可见性。我使用的是ArcGIS Runtime SDK for Android(版本100.1)。
我的问题是,是否可以从要素服务器查看图层的图例到我的图层对话框?意味着要取代3个可爱的图标。
Android应用程序(中间的图层对话框)
要素服务器(左侧图层的图例)
提前谢谢!
感谢falldownhill's suggestion使用Create Swatch!这是我的工作代码
// Loop each layer
for (int x=0; x<featureLayer.length; x++)
{
try
{
// Try get each layer legend
final ListenableFuture<List<LegendInfo>> layerLegend = featureLayer[x].fetchLegendInfosAsync();
final int finalX = x;
layerLegend.addDoneListener(new Runnable()
{
@Override
public void run()
{
try
{
// Get each layer legend
List<LegendInfo> legendInfo = layerLegend.get();
Symbol legendSymbol = legendInfo.get(0).getSymbol();
ListenableFuture<Bitmap> symbolSwatch = legendSymbol.createSwatchAsync(MainActivity.this, Color.TRANSPARENT);
// Set each layer legend
Bitmap symbolBitmap = symbolSwatch.get();
ImageView swatchImg = (ImageView) drawerDialog.findViewById(layerImageViewId[finalX]);
swatchImg.setImageBitmap(symbolBitmap);
}
catch (InterruptedException e)
{
//showMessage("Animation interrupted");
}
catch (ExecutionException e)
{
// Deal with exception during animation...
}
}
});
}
catch (Exception e)
{
// Ignore changing layer legend
}
}
Android应用程序(更新了中间所需图例的图层对话框)
答案 0 :(得分:0)
我认为Create Swatch会做你正在寻找的事情。
只是为了展示一种使用它的方法:
float density = InstrumentationRegistry.getContext().getResources().getDisplayMetrics().density;
for (FeatureType type : featureTable.getFeatureTypes()) {
for (FeatureTemplate template : type.getTemplates()) {
Geometry geometry = //create whatever shape you want the swatch to be
Feature feature = featureTable.createFeature(template, geometry);
Symbol symbol = featureLayer.getRenderer().getSymbol(feature);
ListenableFuture<Bitmap> symbolSwatch = symbol.createSwatchAsync(24, 24,
density,color,feature.getGeometry());
Bitmap swatch = symbolSwatch.get();
}
}
