斑马Android Scanner SDK v2.1.4.0及DEMO

简介：
斑马Android Scanner SDK v2.1.4.0是一款专为安卓设备设计的条形码和二维码扫描开发工具包，提供高效稳定的扫码功能。附带DEMO便于开发者快速集成使用。 斑马Android SDK的部分代码如下所示： ```java public class ScannersActivity extends BaseActivity implements NavigationView.OnNavigationItemSelectedListener, ScannerAppEngine.IScannerAppEngineDevListDelegate { AvailableScannerListAdapter lastConnectedScannerListAdapter; ListView lastConnectedScanner; ArrayList lastConnectedScannerList; AvailableScannerListAdapter availableScannerListAdapter; ListView otherScanners; ArrayList scannersList; // 成员变量 private CustomProgressDialog progressDialog; static AvailableScanner curAvailableScanner = null; int scannerId; static MyAsyncTask cmdExecTask = null; private int REFRESH = 1; private int EVENT = 2; private int CREATE = 3; static boolean launchFromFCS = false; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_scanners); Configuration configuration = getResources().getConfiguration(); if(configuration.orientation == Configuration.ORIENTATION_LANDSCAPE){ if(configuration.smallestScreenWidthDp(); } } ``` 这段代码展示了`ScannersActivity`类的实现，该类继承自`BaseActivity`并实现了多个接口。它包含一些用于管理扫描仪列表和设备连接状态的方法及成员变量，并且在创建视图时根据屏幕方向调整了显示模式。
