**1.初始化MHSDK** **新建****App****.java文件，在****onCreate****方法中添加以下代碼** ``` MHSDK.getInstance().init(this," "); ``` **2.****?初始化美顏界面** **找到****VideoChatViewActivity****.java文件，繼承****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() { ????if (MHSDK.getInstance().isVerEnd()){ ????????setBeautyView(); ????}else { ????????if (beautyThread != null) { ????????????beautyThread.interrupt();

????????mhBeautyManager.setSkinSmooth(0); ????????mhBeautyManager.setSkinTenderness(0); ????} } ``` **在****onCreate****方法中調用****initBeautyView****方法。** **3.****?自定義渲染** **在****VideoChatViewActivity****.java添加以下變量** ``` private GLSurfaceView mGLSurfaceViewLocal; private VideoManager mVideoManager; private SinkConnector mEffectHandler = new SinkConnector() { ????@Override ????public int onDataAvailable(VideoCaptureFrame data) { ????????int textureId = data.mTextureId; ????????int newTexture = textureId; ?????????try { ????????????????if (mhBeautyManager == null) { ????????????????????mhBeautyManager = new MHBeautyManager(getApplicationContext(),true); ????????????????????mhBeautyManager.setBeautyDataModel(BeautyDataModel.getInstance()); ????????????????????if (beautyViewHolder != null) { ????????????????????????beautyViewHolder.setMhBeautyManager(mhBeautyManager); ????????????????????} ????????????????}else{ ????????????????????newTexture = mhBeautyManager.render4(textureId, data.mFormat.mWidth, ?data.mFormat.mHeight); ????????????????} ????????} catch (Exception e) { ????????????e.printStackTrace(); ????????} ????????return newTexture; ????} }; ``` **setupLocalVideo****方法改為以下代碼** ``` ???private void setupLocalVideo() { ????????// This is used to set a local preview. ????????// The steps setting local and remote view are very similar. ????????// But note that if the local user do not have a uid or do ????????// not care what the uid is, he can set his uid as ZERO. ????????// Our server will assign one and return the uid via the event ????????// handler callback function (onJoinChannelSuccess) after ????????// joining the channel successfully. // ???????mLocalView = RtcEngine.CreateRendererView(getBaseContext()); // ???????mLocalView.setZOrderMediaOverlay(true); // ???????mLocalContainer.addView(mLocalView); ????????DisplayMetrics displayMetrics = new DisplayMetrics(); ????????getWindowManager().getDefaultDisplay().getMetrics(displayMetrics); // ???????int height = displayMetrics.heightPixels/2; // ???????int width = displayMetrics.widthPixels/2; // ???????int height = displayMetrics.heightPixels; // ???????int width = displayMetrics.widthPixels; ????????int height = dip2px(300); ????????int width = dip2px(224); ????????Log.d(TAG, "width: " + width + ", height: " + height); // ???????mSmallHeight = height / 3; // ???????mSmallWidth = width / 3; ????????mGLSurfaceViewLocal = new GLSurfaceView(this); ????????if (mLocalContainer.getChildCount() > 0) { ????????????mLocalContainer.removeAllViews(); ????????} ????????mLocalContainer.addView(mGLSurfaceViewLocal, ????????????????FrameLayout.LayoutParams.MATCH_PARENT, ????????????????FrameLayout.LayoutParams.MATCH_PARENT); ????????mVideoManager = VideoManager.createInstance(this); ????????mVideoManager.allocate(width, height, 30, io.agora.kit.media.constant.Constant.CAMERA_FACING_FRONT); ????????mVideoManager.setRenderView(mGLSurfaceViewLocal); ????????mVideoManager.connectEffectHandler(mEffectHandler); // ???????mVideoManager.attachToRTCEngine(getWorker().getRtcEngine()); ????????mVideoManager.attachToRTCEngine(mRtcEngine); ????????mVideoManager.startCapture(); // ???????mRtcEngine.setupLocalVideo(new VideoCanvas(mLocalView, VideoCanvas.RENDER_MODE_HIDDEN, 1001)); ????} ``` **4.設置渲染的寬高** **找到****VideoRender****.java文件，在****onDrawFrame****方法里添加以下代碼** ``` GLES20.glViewport(0, 0, ?mViewWidth, ?mViewHeight); //加上這句 if (mEffectTextureId <= 0) { ????mTextureOES.drawFrame(frame.mTextureId, frame.mTexMatrix, mMVP); } else { ????frame.mTextureId = mEffectTextureId; ????mFullFrameRectTexture2D.drawFrame(frame.mTextureId, frame.mTexMatrix, mMVP); } ```
