问题详细描述：Android使用SceneMapControl绑定VideoEffectView2后再刷新时显示空指针异常
问题重现步骤： 1.在activity_main.xml获取到VideoEffectView2和SceneMapControl的实例；
2、播放视频，打开地图，设置空间位置参数，SceneMapControl使用bindView()方法绑定VideoEffectView2；
3、调用SceneMapControl.refresh() 方法
sceneMapControl = findViewById(R.id.supermap_scene_map_control);
videoEffectView = findViewById(R.id.supermap_effect_view);
sceneMapControl.bindEffectView(videoEffectView);
sceneMapControl.setCacheFolderPath( sdcard + "/SuperMap/data/Cache_tmp/" , new PrjCoordSys(3857) );
sceneMapControl.setUseCache(true);
videoEffectView.setDeviceLocation( new Location( 114.093782007694, 22.5494760274886 , 100 ));
videoEffectView.getSceneView().getScene().getCamera().setWorldRotation( new Quaternion(30,30,30,30));
videoEffectView.getSceneView().getScene().getCamera().setWorldPosition( new Vector3( 114 , 22 ,100 ));
Workspace workspace = new Workspace();
WorkspaceConnectionInfo info = new WorkspaceConnectionInfo();
info.setServer(sdcard+"/SuperMap/data/World.smwu");
info.setType(WorkspaceType.SMWU);
workspace.open(info);
//获取地图对象，并打开指定地图
Map map = sceneMapControl.getMap();
map.setWorkspace( workspace );
map.setPrjCoordSys( new PrjCoordSys(3857) );
map.open("map1");
map.setScale( 0.0002 );
map.setCenter( new Point2D(114,22) );
map.refresh();
sceneMapControl.addOnAttachStateChangeListener(new View.OnAttachStateChangeListener() {
@Override
public void onViewAttachedToWindow(@NonNull View v) {
Timer timer = new Timer();
timer.schedule(new TimerTask() {
@Override
public void run() {
try {
sceneMapControl.refresh( 114.093782007694, 22.5494760274886,"12", false);
}catch (Exception e){
Log.v("refresh",e.toString());
}
}
} , 3000, 500 );
}
@Override
public void onViewDetachedFromWindow(@NonNull View v) {
}
});
try {
videoEffectView.getMediaPlayer().setDataSource( sdcard + "/SuperMap/data/Videos/video_60fps.mp4" );
videoEffectView.getMediaPlayer().prepare();
videoEffectView.getMediaPlayer().start();
}catch (Exception e){
Log.v("media",e.toString());
}
