附加信息

The flicker has nothing to do with Android Studio and instead is a result of the `MapView` being contained in a `RelativeView` with a layout behavior defined as the following: `app:layout_behavior="@string/appbar_scrolling_view_behavior"` This means the relative layout actually scrolls on pan and causes the MapView to be re-positioned slightly on screen causing the black flickering. If users comment the line above in **content_main.xml** the application works as expected. This is a known issue.

解决办法

1. Construct the MapView in Java instead of XMLMapView myMapView = new MapView(MainActivity.this,null,null);myMapView.addLayer(new ArcGISDynamicMapServiceLayer("<a href="http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer" target="_blank">http://services.arcgisonline.com/ArcGIS/rest/services/World_Street_Map/MapServer</a>")); setContentView(myMapView);- To construct the MapView in XML set the parameter of setContentView method in MainActivityJava to content_main instead of activity_main.setContentView(R.layout.content_main);
