How to keep the callout sticky when users move map?

LeoDeng — Fri, 20 Jan 2023 06:56:26 GMT

Hi All,

The SDK version is 100.15.0

I create a point graphic with callout on the mapview. When panning the map, the callout always has a gap between the arrow and the graphic. Is there any way to solve this issue in Android SDK ?

Here is the code for create a callout with a point graphic.

Callout callout = _mapView.getCallout(); callout.setPassTouchEventsToMapView(false); TextView calloutContent = new TextView(_context); calloutContent.setTextColor(Color.BLACK); calloutContent.setSingleLine(); // format coordinates to 4 decimal places calloutContent.setText("Lat: " + String.format("%.4f", location.getY()) + ", Lon: " + String.format("%.4f", location.getX())); callout.show(calloutContent, location);

Please see the attached video for details.

Bests,
Leo

Hey @LeoDeng

Using a callout probably wouldn't best choice for "perfect stickiness". I would recommend using a `TextSymbol`

graphicsOverlay?.graphics?.add( Graphic( Point(40.0, -90.0, SpatialReferences.getWgs84()), getTextSymbol("Lat: 40.0, Lon: -90.0") ) ) private fun getTextSymbol(text: String): TextSymbol { val textSymbol = TextSymbol( 10F, text, Color.BLACK, TextSymbol.HorizontalAlignment.CENTER, TextSymbol.VerticalAlignment.MIDDLE ) // give the text symbol a white background textSymbol.backgroundColor = Color.WHITE return textSymbol }

Check out the Render multilayer symbols Android Runtime sample, which shows different kinds of multilayer symbols on a map including rendering TextSymbols.

Thank you @Shubham_Sharma .

Actually, I tried "TextSymbol" solution too. However, in this solution, I met another problem. I'm not sure if there is a solution which can solve both of the problems.
