地图上呼吸灯效果圆形动画（自用备忘）

初始化： final Animation animationVoice = AnimationUtils.loadAnimation(this,R.anim.voice_button_anim);voice_back.startAnimation(animationVoice);

资源文件：anim文件：

动态计算地图坐标进行转换位置变化：

mSceneView.addViewpointChangedListener(new ViewpointChangedListener() {

                    @Override
                    public void viewpointChanged(ViewpointChangedEvent viewpointChangedEvent) {
                        for (int i = 0; i < viewpointChangedEvent.getSource().getGraphicsOverlays().size(); i++) {
                            if (viewpointChangedEvent.getSource().getGraphicsOverlays().get(i) == mGraphicsOverlay) {
                                voice_back.setVisibility(View.VISIBLE);
                                LocationToScreenResult point = mSceneView.locationToScreen((Point) viewpointChangedEvent.getSource().getGraphicsOverlays().get(i).getGraphics().get(0).getGeometry());
                                voice_back.setAnimation(animationVoice);

                                WidgetController.setLayout(voice_back, point.getScreenPoint().x, point.getScreenPoint().y);
                                voice_back.setAnimation(animationVoice);
                                Log.e("hsjdahdapoint", point.getScreenPoint().x + "");
                            }
                        }
                    }
                });

WidgetController.setLayout(voice_back, point.getScreenPoint().x, point.getScreenPoint().y);
