TextField(concat(Expression.toString(get("temperature")), literal("☏"))),įor this sample, the following image is loaded into the drawable folder of the app.
IconSize(0.5f), //Get the title property of the feature and display it on the map. Load a custom icon image into the image sprite of the map. The title property is displayed as text above the symbol icon on the map.
The following code sample creates a GeoJSON Point geometry and passes it into the GeoJSON Feature and has a title value added to its properties. GeoJSON Feature - This object consists of any GeoJSON geometry and a set of properties that contain metadata associated to the geometry.įor more information, see the Create a data source document on creating and adding data to the map.Pass an array of points into the MultiPoint class to create these objects. GeoJSON MultiPoint geometry - This object contains the coordinates of multiple points and nothing else.
The omLngLat static method can be used to easily create these objects. GeoJSON Point geometry - This object only contains a coordinate of a point and nothing else.There are three different types of point data that can be added to the map: Create a symbol layer to render icons and/or text at points on the map. Create a point and add it to the data source. Create a data source and add it to the map. This sample renders a single point on the map using a symbol layer. The code below demonstrates what should be added to the map after it has loaded. Finally, add data into the data source, so that there's something to be rendered. Then, pass in the data source to the symbol layer, to retrieve the data from the data source. First, create a data source, and add it to the map. Add a symbol layerīefore you can add a symbol layer to the map, you need to take a couple of steps. Code blocks in this article can be inserted into the maps onReady event handler. Prerequisitesīe sure to complete the steps in the Quickstart: Create an Android app document. If you want to include MultiPoint features as well, set the filter option of the layer to any(eq(geometryType(), "Point"), eq(geometryType(), "MultiPoint")). To limit the layer so that it only renders point geometry features, set the filter option of the layer to eq(geometryType(), "Point"). Symbol layers by default will render the coordinates of all geometries in a data source.
