I was writing a program where I needed to check properties of various fields, and so I decided to use the ArcGISFeatureLayer.getField(String fieldName) but kept experiencing errors. The return value was always null. So as a quick test, I did this...final ArcGISFeatureLayer testLayer = new ArcGISFeatureLayer(
"http://sampleserver3.arcgisonline.com/ArcGIS/rest/services/Petroleum/KSFields/FeatureServer/0",
MODE.SNAPSHOT);
testLayer.setOnStatusChangedListener(new OnStatusChangedListener() {
private static final long serialVersionUID = 1L;
public void onStatusChanged(Object arg0, STATUS arg1) {
if (arg1 == STATUS.INITIALIZED) {
Field[] fields = testLayer.getFields();
Log.d(TAG, featureLayer.getName() + ": found " + fields.length + " fields");
boolean found = false;
for (Field field : fields) {
if (testLayer.getField(field.getName()) != null) {
Log.d(TAG, featureLayer.getName() + ": found field object for " + field.getName());
found = true;
}
}
if (!found) {
Log.d(TAG, featureLayer.getName() + ": no field objects found by name");
}
}
}
});
Which results in!! Current Kansas Field Production: found 23 fields
!! Current Kansas Field Production: no field object found by name
Why does getField(fieldName) always return null?
