//初始化  1.QRCodeSupport mQRCodeSupport = new QRCodeSupport(mSurfaceView,mFinderView);      //设计监听  2.mQRCodeSupport.setScanResultListener(new QRCodeSupport.OnScanResultListener(){                                              @Override                                              public void onScanResult(String notNullResult) {                                                }                                         };);    3.在activity 或者 fragment  onResume 和  onPause   调用次QRCodeSupport 的方法。        @Override        protected void onResume() {            super.onResume();            mQRCodeSupport.onResume();        }          @Override        protected void onPause() {            super.onPause();            mQRCodeSupport.onPause();        }
