海康PDA扫码支持

1、在需要实体按键扫码的activity里增加如下变量和函数：

   ScanDataReceiver mScanServiceReceiver;

    private void registerReceiver() {

        // 动态注册广播

        mScanServiceReceiver = new ScanDataReceiver(new ScanDataReceiver.CodeListener() {

            @Override

            public void onCallback(String data) {

            /*

                此处处理接收到的二维码data

                loadBarcode(data);

            */

            }

        });

        IntentFilter intentFilter = new IntentFilter();

        intentFilter.addAction(CGlobal.ACTION_PDA_SERVICE_SCANNER_DATA);

        registerReceiver(mScanServiceReceiver, intentFilter);

    }

    private void unRegisterReceiver() {

        if (mScanServiceReceiver != null) {

            unregisterReceiver(mScanServiceReceiver);

        }

    }

2、在 onCreate中调用registerReceiver()

3、在 onDestroy中调用 unRegisterReceiver()
