## &#x20;VuiService.java语音Vui服务（带有语音形象的app）

透明activity无法跨应用实现点击穿透效果，会导致可见即可说点击无效果，需要在service中使用WindowManager的addview方法，把语音的app作为view添加到WindowManager中,这样就可以实现语音app全透明状态下识别到asr之后可以利用Android无障碍服务去点击指定位置或者指定控件。public class VoiceVuiService extends Service {private WindowManager.LayoutParams mParams;private WindowManager mWindowManager;private ImageView voiceImage;private TextView textView;@Overridepublic void onCreate() {mParams = new WindowManager.LayoutParams();//设置type.系统提示型窗口，一般都在应用程序窗口之上.mParams.type = WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY;
