在安卓(Android)下如何选择和开发IC卡读卡器
1、打开adt软件，新建一个Android工程。
2、在菜单build path下引入IC卡读卡器android的开发包YowoRFIDreader.jar
3、在主界面中设计读写的界面，防止相应的控件
4、开始写主程序了，在读和写按钮分别写入以下的程序：
Button button = (Button) findViewById(R.id.btnreadCard);
button.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
txtCardNo.setText("");
edtData.setText("");
int BlockID = MainActivity.ValidInt( edtBlockID.getText().toString() , 63);
if(BlockID<0)
{
MainActivity.dialog("块号必须是0-63",M1.this);
return;
}
if(!MainActivity.ValidHexString(edtKey.getText().toString(), 6))
{
MainActivity.dialog("密钥必须是6字节16进制",M1.this);
return;
}
if( MainActivity.rfidreader.ISO14443A.YW_RequestCard(MainActivity.rfidreader.ISO14443A.REQUESTMODE_ALL)<0)return;
byte[] CardNo=MainActivity.rfidreader.ISO14443A.YW_AntiCollideAndSelect(MainActivity.rfidreader.ISO14443A.MULTIMODE_ONE);
if(CardNo==null)return;
txtCardNo.setText("卡号：" + MainActivity.bytesToHexString(CardNo));
byte KeyMode=MainActivity.rfidreader.ISO14443A.Key_B;
if(rbKeyA.isChecked())KeyMode=MainActivity.rfidreader.ISO14443A.Key_A;
if(MainActivity.rfidreader.ISO14443A.YW_KeyAuthorization(KeyMode, BlockID, MainActivity.HexStringtoBytes( edtKey.getText().toString()))<0)
{
MainActivity.dialog("密钥认证错误",M1.this);
return;
}
byte[] Data = MainActivity.rfidreader.ISO14443A.YW_ReadaBlock(BlockID);
if(Data==null)
{
MainActivity.dialog("读取块失败",M1.this);
return;
}
edtData.setText(MainActivity.bytesToHexString(Data));
MainActivity.rfidreader.ReaderHardware.YW_Buzzer(5, 5, 1);
}
});
Button button2 = (Button) findViewById(R.id.btnwritedata);
button2.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
txtCardNo.setText("");
int BlockID = MainActivity.ValidInt( edtBlockID.getText().toString() , 63);
if(BlockID<0)
{
MainActivity.dialog("块号必须是0-63",M1.this);
return;
}
if(!MainActivity.ValidHexString(edtKey.getText().toString(), 6))
{
MainActivity.dialog("密钥必须是6字节16进制",M1.this);
return;
}
if(!MainActivity.ValidHexString(edtData.getText().toString(), 16))
{
MainActivity.dialog("数据必须是16字节16进制",M1.this);
return;
}
if( MainActivity.rfidreader.ISO14443A.YW_RequestCard(MainActivity.rfidreader.ISO14443A.REQUESTMODE_ALL)<0)return;
byte[] CardNo=MainActivity.rfidreader.ISO14443A.YW_AntiCollideAndSelect(MainActivity.rfidreader.ISO14443A.MULTIMODE_ONE);
if(CardNo==null)return;
txtCardNo.setText("卡号：" + MainActivity.bytesToHexString(CardNo));
byte KeyMode=MainActivity.rfidreader.ISO14443A.Key_B;
if(rbKeyA.isChecked())KeyMode=MainActivity.rfidreader.ISO14443A.Key_A;
if(MainActivity.rfidreader.ISO14443A.YW_KeyAuthorization(KeyMode, BlockID, MainActivity.HexStringtoBytes( edtKey.getText().toString()))<0)
{
MainActivity.dialog("密钥认证错误",M1.this);
return;
}
byte[] Data = MainActivity.HexStringtoBytes(edtData.getText().toString());
if(MainActivity.rfidreader.ISO14443A.YW_WriteaBlock(BlockID, Data)>0)
{
MainActivity.dialog("数据写入成功",M1.this);
MainActivity.rfidreader.ReaderHardware.YW_Buzzer(5, 5, 1);
}
else
MainActivity.dialog("数据写入失败",M1.this);
}
});
}
5、写好后，编译，生成apk安装包，在手机上插上ＯＴＧ数据线和IC卡读卡器YW-605HA或者NFC读写器YW-607,出现如下界面：
6、点击读和写都显示成功
