**1.初始化MHSDK** **找到****MyApplication****.java文件，在****onCreate****方法中添加以下代码：** ``` MHSDK.getInstance().init(this," "); ``` **2.**** 初始化美颜界面** **找到****LiveChatActivity****.java文件，继承****DefaultBeautyEffectListener****接口，添加以下变量：** ``` 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();             beautyThread = null;         }         beautyThread = new BeautyThread(this);         beautyThread.start();     } } private void showRetryDialog() {     if (dialog != null) {         dialog.cancel();     }     SDKDialogListener diaLogListener = new SDKDialogListener(this);     dialog = new AlertDialog.Builder(this)             .setTitle("提示")             .setMessage("资源获取失败，请检查网络")             .setCancelable(false)             .setPositiveButton("确定", diaLogListener)             .create();     dialog.show(); } private void showExitDialog() {     if (dialog != null) {         dialog.cancel();     }     DiaLogListener diaLogListener = new DiaLogListener(this);     dialog = new AlertDialog.Builder(this)             .setTitle("提示")             .setMessage("资源获取失败，请检查网络并退出重试")             .setCancelable(false)             .setPositiveButton("确定", diaLogListener)             .create();     dialog.show(); } 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);     beautyViewHolder.show();     beautyViewHolder.setEffectListener(this);     beautyViewHolder.setVisibleListener(visible -> {         if (!visible) {             beautyViewHolder.show();         }     });     beautyViewHolder.setMhBeautyManager(mhBeautyManager); } static class DiaLogListener implements DialogInterface.OnClickListener {     WeakReference activityWeakReference;     DiaLogListener(LiveChatActivity activity) {         this.activityWeakReference = new WeakReference<>(activity);     }     @Override     public void onClick(DialogInterface dialog, int which) {         LiveChatActivity activity = activityWeakReference.get();         if (activity == null)return;         switch (which){             case -1:                 dialog.cancel();                 activity.finish();                 break;             case -2:                 dialog.cancel();                 break;         }     } } static class SDKDialogListener implements DialogInterface.OnClickListener {     WeakReference activityWeakReference;     SDKDialogListener(LiveChatActivity activity) {         this.activityWeakReference = new WeakReference<>(activity);     }     @Override     public void onClick(DialogInterface dialog, int which) {         LiveChatActivity activity = activityWeakReference.get();         if (activity == null)return;         switch (which){             case -1:                 activity.retryCount ++;                 MHSDK.getInstance().clearVerNote();                 MHSDK.getInstance().verify("");                 activity.initBeautyView();                 dialog.cancel();                 break;             case -2:                 dialog.cancel();                 break;         }     } } static class BeautyThread extends  Thread {     WeakReference mainActivityWeakReference;     BeautyThread(LiveChatActivity txMainActivity) {         this.mainActivityWeakReference = new WeakReference<>(txMainActivity);     }     @Override     public void run() {         while (mainActivityWeakReference.get()!= null && !MHSDK.getInstance().isVerEnd()) {             if (isInterrupted()) return;             try {                 Thread.sleep(200);             } catch (InterruptedException e) {                 e.printStackTrace();             }         }         LiveChatActivity activity = mainActivityWeakReference.get();         if (activity != null){             activity.mHandler.post(activity::setBeautyView);         }     } } @Override public void onFilterChanged(FilterBean filterBean) {     if (mhBeautyManager == null) {         return;     }     FilterEnum filterEnum = filterBean.getFilterEnum();     if (filterEnum == FilterEnum.PRO_FILTER) {         mhBeautyManager.changeDynamicFilter(filterBean.getmFilterName());     } else {         Bitmap lookupBitmap = BitmapUtil.getFilterBitmap(this,filterEnum);         mhBeautyManager.setFilter(lookupBitmap);     } } @Override public void onMeiBaiChanged(int progress) {     if (mhBeautyManager != null) {         mhBeautyManager.setSkinWhiting(progress);     } } @Override public void onMoPiChanged(int progress) {     if (mhBeautyManager != null) {         mhBeautyManager.setSkinSmooth(progress);     } } @Override public void onFengNenChanged(int progress) {     if (mhBeautyManager != null) {         mhBeautyManager.setSkinTenderness(progress);     } } @Override public void onBeautyOrigin() {     if (mhBeautyManager != null) {         mhBeautyManager.setSkinWhiting(0);         mhBeautyManager.setSkinSmooth(0);         mhBeautyManager.setSkinTenderness(0);     } } ``` **在****onCreate****方法中调用****initBeautyView****方法。** **3.**** 自定义渲染** **在****LiveChatActivity****.java文件，添加以下代码：** ``` 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;     } }; ``` **4.设置渲染的宽高** **找到****VideoRender****.java文件，在****onDrawFrame****方法里添加以下代码：** ``` GLES20.glViewport(0, 0,  mViewWidth,  mViewHeight); //加上这句 if (mEffectTextureId <= 0) {     mTextureOES.drawFrame(frame.mTextureId, frame.mTexMatrix, mMVP); } else {     frame.mTextureId = mEffectTextureId;     mFullFrameRectTexture2D.drawFrame(frame.mTextureId, frame.mTexMatrix, mMVP); } ```
