Android Zebra RFIDReader 网络监控代码示例 (无需Activity)

以下是一个示例代码，用于在网络环境较差的情况下实时监控网络变化并重新连接RFIDReader。

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.content.IntentFilter;
import android.net.ConnectivityManager;
import android.net.NetworkInfo;

import com.zebra.rfid.api3.RFIDReader;

public class RFIDReaderManager {
    private Context context;
    private RFIDReader rfidReader;
    private ConnectivityManager connectivityManager;
    private NetworkChangeReceiver networkChangeReceiver;

    public RFIDReaderManager(Context context, RFIDReader rfidReader) {
        this.context = context;
        this.rfidReader = rfidReader;
        this.connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
        this.networkChangeReceiver = new NetworkChangeReceiver();
    }

    public void startMonitoringNetworkChanges() {
        IntentFilter intentFilter = new IntentFilter();
        intentFilter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
        context.registerReceiver(networkChangeReceiver, intentFilter);
    }

    public void stopMonitoringNetworkChanges() {
        context.unregisterReceiver(networkChangeReceiver);
    }

    private void reconnectRFIDReader() {
        // 在这里重新连接RFIDReader，例如重新初始化RFIDReader对象并尝试重新连接
        // rfidReader.reconnect();
    }

    private class NetworkChangeReceiver extends BroadcastReceiver {
        @Override
        public void onReceive(Context context, Intent intent) {
            if (intent.getAction().equals(ConnectivityManager.CONNECTIVITY_ACTION)) {
                NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
                if (networkInfo != null && networkInfo.isConnected()) {
                    // 网络连接恢复
                    reconnectRFIDReader();
                }
            }
        }
    }
}

使用示例：

// 创建RFIDReader对象
RFIDReader rfidReader = new RFIDReader();
// 创建RFIDReaderManager对象
RFIDReaderManager rfidReaderManager = new RFIDReaderManager(context, rfidReader);
// 启动网络变化监控
rfidReaderManager.startMonitoringNetworkChanges();
// 在需要的地方停止网络变化监控
rfidReaderManager.stopMonitoringNetworkChanges();

请注意，这只是一个示例代码，具体实现可能需要根据你的具体情况进行调整。另外，你可能还需要在AndroidManifest.xml文件中声明对网络状态的权限：

<uses-permission android:name='android.permission.ACCESS_NETWORK_STATE' />
