**1.初始化MHSDK** **找到****ZegoApplication****.java文件，初始化SDK** ``` ?????MHSDK.getInstance().init(this," "); ``` **2.初始化即構濾鏡接口** **找到****VideoCommunicationMainUI****.java文件，新增變量如下：** ``` public static VideoFilterFactoryDemo filterFactory; ``` **在****onCreate****初始化ZegoSDK設置自定義濾鏡。** ``` filterFactory = new VideoFilterFactoryDemo(FilterType_HybridMem, null); ZegoExternalVideoFilter.setVideoFilterFactory(filterFactory, ZegoConstants.PublishChannelIndex.MAIN); ``` **3.初始化美顏界面** **找到****PublishStreamAndPlayStreamUI****.java文件****，****實現****DefaultBeautyEffectListener****接口****，****添加以下變量****：** ``` private Handler mHandler; private AlertDialog dialog; private RelativeLayout beautyContainer; private MHBeautyManager mhBeautyManager; private BaseBeautyViewHolder beautyViewHolder; private boolean isResume; private int retryCount; private Thread beautyThread; ``` **添加以下方法** ``` private void initBeautyView() { ????????beautyContainer = findViewById(R.id.beauty_view_container); ????????mHandler = new Handler(getMainLooper()); ????????if (MHSDK.getInstance().isVerEnd()){ ????????????setBeautyView(); ????????}else { ????????????if (beautyThread != null) { ????????????????beautyThread.interrupt(); ????????????????beautyThread = null; ????????????} ????????????beautyThread = new BeautyThread(this); ????????????beautyThread.start(); ????????} ????} ????private void setBeautyView(){ ????????LogManager.getInstance().writeData("MainActivity_setBeautyView_SDKVersion=" + MHSDK.getInstance().getVer()); ????????if (!MHSDK.getInstance().isVerifyAccess()){ ????????????if (retryCount < 10) { ????????????????showRetryDialog(); ????????????}else { ????????????????showExitDialog(); ????????????????return; ????????????} ????????} ????????if (beautyViewHolder != null) { ????????????beautyViewHolder.release(); ????????????beautyViewHolder = null; ????????} ????????beautyViewHolder = BeautyViewHolderFactory.getBeautyViewHolder(getApplicationContext(), beautyContainer);

????????????} ????????}); ????????mhBeautyManager = new MHBeautyManager(this,true); ????????beautyViewHolder.setMhBeautyManager(mhBeautyManager); ????????VideoCommunicationMainUI.filterFactory.setMHBeautyManager(mhBeautyManager);

????????} ????} ????@Override ????public void onBeautyOrigin() { ????????if (mhBeautyManager != null) { ????????????mhBeautyManager.setSkinWhiting(0); ????????????mhBeautyManager.setSkinSmooth(0); ????????????mhBeautyManager.setSkinTenderness(0); ????????} ????} ????static class DiaLogListener implements DialogInterface.OnClickListener { ????????WeakReference activityWeakReference; ????????DiaLogListener(PublishStreamAndPlayStreamUI activity) { ????????????this.activityWeakReference = new WeakReference<>(activity);

????????????????????break; ????????????} ????????} ????} ``` ????//由于demo進入應用直接進入美顏界面，為了防止授權校驗未完成而一直顯示標準版界面，需要等授權校驗完成后初始化對應的美顏界面（延遲1秒或者按下面處理） ``` ????static class BeautyThread extends ?Thread { ????????WeakReference mainActivityWeakReference; ????????BeautyThread(PublishStreamAndPlayStreamUI PublishStreamAndPlayStreamUI) { ????????????this.mainActivityWeakReference = new WeakReference<>(PublishStreamAndPlayStreamUI); ????????} ????????@Override ????????public void run() { ????????????while (mainActivityWeakReference.get()!= null && !MHSDK.getInstance().isVerEnd()) { ????????????????if (isInterrupted()) return; ????????????????try { ????????????????????Thread.sleep(200); ????????????????} catch (InterruptedException e) { ????????????????????e.printStackTrace(); ????????????????} ????????????} ????????????PublishStreamAndPlayStreamUI activity = mainActivityWeakReference.get(); ????????????if (activity != null){ ????????????????activity.mHandler.post(activity::setBeautyView); ????????????} ????????} ????} ????private void showRetryDialog() { ????????if (dialog != null) { ????????????dialog.cancel();

????????dialog.show(); ????} ``` **在****onCreate****里調用****initBeautyView()****方法** **4.實現濾鏡接口** **找到****VideoFilterFactoryDemo****.java文件，添加以下方法** ``` public void setMHBeautyManager(MHBeautyManager mhBeautyManager){ ????mFunRender = mhBeautyManager; ????((VideoFilterHybridDemo)mFilter).setMHBeautyManager(mhBeautyManager); } ``` **找到****VideoFilterHybridDemo****.java文件，找到****queueInputBuffer****方法，添加以下代碼** ``` int textureID = mTextureId; if(mMHBeautyManager!=null){ ????textureID = mMHBeautyManager.render6(mTextureId, pixelBuffer.width, pixelBuffer.height); } // 此步驟會使用此 textureID 用做本地預覽的視圖渲染，并將美顏后的 textureID 傳給 SDK（拉該條流時是美顏后的視頻） mClient.onProcessCallback(textureID, pixelBuffer.width, pixelBuffer.height, pixelBuffer.timestamp_100n); ```
