Currently, SketchEdtior doesn't work with the magnifier seamlessly. By default, when the magnifier is released up, it doesn't do anything.
There is a workaround for your consideration :
1. The workflow is to create a new inner TouchListener class to the class where your MapView resides, swap the default sketch touch listener when you want to enable the magnifier to add a vertex when it is released, and swap back the original sketch touch listener. The like this :
private DefaultMapViewOnTouchListener mSketchEventListenerRestore;
private AddVertexMagnifierListener mAddVertexMagnifierListener;
class AddVertexMagnifierListener extends DefaultMapViewOnTouchListener {
/**
* Constructs a DefaultMapViewOnTouchListener with the given Context and MapView.
*
* @param context the context from which this is being created
* @param mapView the MapView with which to interact
* @since 100.0.0
*/
public AddVertexMagnifierListener(Context context, MapView mapView) {
super(context, mapView);
}
@Override public boolean onUp(MotionEvent e) {
boolean ret = super.onUp(e);
//Check condition to add a vertex when the magnifier is up.
boolean isStarted = mMapView.isMagnifierEnabled(); //&& SketchEditor is started
if (isStarted) {
Point point = mMapView.screenToLocation(new android.graphics.Point((int)e.getX(), (int)e.getY()));
mSketchEditor.insertVertexAfterSelectedVertex(point);
}
return ret;
}
}
2. When you start the SketchEditor, save the default the listener,
mSketchEditor.start(SketchCreationMode.POLYGON, mSketchEditor.getSketchEditConfiguration());
//save the default sketch listener
sketchEventListenerRestore = (DefaultMapViewOnTouchListener) mMapView.getOnTouchListener();
3. When you enable the magnifier, use the new touch listener or use the original one.
/**
* Toggles showing the magnifier
*/
private void toggleMagnifier() {
mMapView.setMagnifierEnabled(!mMapView.isMagnifierEnabled());
if (mMapView.isMagnifierEnabled()) {
if (mAddVertexMagnifierListener == null) {
mAddVertexMagnifierListener = new AddVertexMagnifierListener(this, mMapView);
}
mMapView.setOnTouchListener(mAddVertexMagnifierListener);
} else {
mMapView.setOnTouchListener(mSketchEventListenerRestore);
}
Toast.makeText(this, "Magnifier="+mMapView.isMagnifierEnabled(), Toast.LENGTH_LONG).show();
}Hope this is helpful to you.
We may consider making the magnifier work closely with SketchEditor in the future release.
