Hi,

the simplest answer is to remove unnecessary field from the shapefile schema. Follow this guide: Deleting fields—Help | ArcGIS for Desktop.

 Also, you can try to query shapefile setting output fields in the QueryParameters- that should work too.

Hope this helps,

Adam

Thanks Adam,

But I have tried the setoutfiled in the QueryParameters.But it seems to return all the field since the popupview still display all the field.The related code is showed as follows.

callback

CallbackListener<FeatureResult> callback=new CallbackListener<FeatureResult>() {

@Override
public void onError(Throwable e) {
// JOptionPane.showMessageDialog(contentPane, wrap("Error: "+e.getLocalizedMessage()), "", JOptionPane.ERROR_MESSAGE);
System.out.println("QUERY ERROR");
}

@Override
public void onCallback(FeatureResult objs) {
for (Object objFeature : objs) {
Feature feature = (Feature) objFeature;
//System.out.println(feature.getAttributes());
createPopView(feature);
}
}
};

query

private final String[] ATTR_NAMES =
new String[] {"NAME_0", "NAME_1", "NAME_2"};

QueryParameters query = new QueryParameters();
query.setOutFields(ATTR_NAMES);

shapefileTable_lf.queryFeatures(query,callback);

function createPopView

private void createPopView(Feature feature)
{
PopupView contentPanel = PopupView.createAttributesView((String)feature.getAttributeValue("NAME_3"), feature);
//display feature
contentPanel.setFeature(map, feature);
PopupDialog popup = map.createPopup(new JComponent[]{contentPanel}, feature);
popup.setTitle("水资源情况");
popup.setVisible(true);
}
