The purpose of this sample is to show how to customize the UI of a pop-up. The layout and style of a pop-up can be changed through XML files and extending some built-in classes of the pop-up API.
- Popup API
- MapViewHelper
This sample shows how to customize the UI of a pop-up and two ways of creating pop-ups. The simplest way is to utilize a helper class from ArcGIS Android Application Tookit called MapViewHelper to create pop-ups with default UI. The MapViewHelper class will iterate through and query each layer in the MapView. A pop-up will be created for each feature in the query result and will be added to a PopupContainer. The user-defined PopupCreateListener is called after the pop-ups are created. You can use the logic in the PopupCreateListener to display the pop-ups.
Another approach is more complicated but more powerful. This approach allows users to customize the UI of a pop-up. In this sample a class called LayerQueryTask demonstrates this approach. LayerQueryTask loops through each layer and queries the MapView in an asynchronous task. The asynchronous task will create pop-ups for the query result. Before a pop-up is created, a new PopupLayoutInfo will be populated from XML file and be passed to Layer.createPopup() as a parameter. Then the four basic views such as title, attribute, media and attachment view will be modified by instantiating the sub-classes of the built-in classes of the views. The style of the views then can be customized through these sub-classes and XML files.
Pop-ups will be display in a fragment called PopupFragment. This fragment also provides menu to edit or delete a feature based on the edit properties of the feature.
The Popup samples depend on the Application Tookit for ArcGIS Android and the Andriod Support Library.
NOTE: The PopupUICustomization sample depends on the Android Support Library and is included in the sample as a compile time depedency in the modules build.gradle file.
