新大陆实训平台—Android调用RFID.jar包

RFID(2020/10/08)
注意：在F:\Android\RFID\app\src\main\AndroidManifest.xml文件加网络权限
1.EditText设置边框

?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android">
    <item>
        <shape
            android:shape="rectangle">
            <solid
                android:color="#FFF"/>
            <corners
                android:radius="3dip"/>
            <stroke
                android:width="0.5px"
                android:color="#505050"/>
        </shape>
	</item>
</layer-list>

2.语音播报

public void tts(String text){
        tts = new TextToSpeech(this, new TextToSpeech.OnInitListener() {
        @Override
            public void onInit(int i) {
                tts.setLanguage(Locale.CHINESE);
                tts.speak(text, TextToSpeech.QUEUE_ADD, null);
            }
        });
    }

3.数据存储
存数据

public void keep() {
        SharedPreferences.Editor edit = sp.edit();
        edit.putString("id",etID.getText().toString().trim());
        edit.putString("name",etName.getText().toString().trim());
        edit.putString("money",etMoney.getText().toString().trim());
        edit.commit();

        Toast.makeText(this,"数据写入成功！", Toast.LENGTH_SHORT).show();
    }

三张卡号：

E2 00 00 1B 21 11 01 92 06 30 A5 E8
E2 00 00 1B 21 11 01 71 06 30 96 25
E2 00 00 1B 21 11 02 06 06 30 B6 BB

取数据，在init函数中添加

sp = getSharedPreferences("User", Context.MODE_PRIVATE);
//获取上次存储的值，显示出来
etID.setText(sp.getString("id",""));
etName.setText(sp.getString("name",""));
etMoney.setText(sp.getString("money",""));

4.RFID线程

public void RFID(){
        rfid = new RFID(DataBusFactory.newSocketDataBus("192.168.1.16", 2005));
        Timer timer=new Timer();
        timer.schedule(new TimerTask() {
		@Override
        public void run() {
            try {
                rfid.readSingleEpc(new SingleEpcListener() {
                    @Override
                    public void onVal(String val) {
                        Message msg = Message.obtain();
                        msg.obj = val;
                        msg.what = 1;
                        handler.sendMessage(msg);
                    }
                });
            } catch (Exception e) {
                e.printStackTrace();
            }
        }
    }, 1000L,1000L);
}

    @SuppressLint("HandlerLeak")
    Handler handler=new Handler(){
    @SuppressLint("WrongConstant")
    public void handleMessage(android.os.Message msg) {
        String cardid=	(String) msg.obj;

        Toast.makeText(MainActivity.this, ""+cardid, 0).show();
        if(cardid.equals("E2 00 00 1B 21 11 01 71 06 30 96 25")){
            tts("24");
            etID.setText(cardid);
            etName.setText("员工A");
            etMoney.setText("24元");

        }else if(cardid.equals("E2 00 00 1B 21 11 01 92 06 30 A5 E8")){
            tts("30");
            etID.setText(cardid);
            etName.setText("员工B");
            etMoney.setText("30元");
        }else if(cardid.equals("E2 00 00 1B 21 11 02 06 06 30 B6 BB")){
            tts("27");
            etID.setText(cardid);
            etName.setText("员工C");
            etMoney.setText("27元");
        }
        keep();
    };
};
