android4串口编程实例
在Android上进行串口编程需要使用Android的串口API。以下是一个简
单的Android串口编程示例，演示如何打开串口、读取数据和关闭串口。
1. 在中添加以下权限：
```xml
```
2. 创建一个继承自SerialPort的类，实现串口通信：
```java
import ;
import ;
import ;
import ;
public class SerialPortUtil {
private SerialPort serialPort;
private InputStream inputStream;
private OutputStream outputStream;
private Thread readThread;
public SerialPortUtil(String path, int baudRate) throws IOException
{
serialPort = new SerialPort(path, baudRate, 0);
inputStream = ();
outputStream = ();
readThread = new Thread(new SerialPortReadRunnable());
();
}
public void write(byte[] data) throws IOException {
(data);
}
public void close() throws IOException {
if (serialPort != null) {
();
}
if (inputStream != null) {
();
}
if (outputStream != null) {
();
}
if (readThread != null) {
();
}
}
private class SerialPortReadRunnable implements Runnable {
Override
public void run() {
byte[] buffer = new byte[1024];
int len;
while (!()) {
try {
len = (buffer);
if (len > 0) {
// 处理读取到的数据...
} else {
(100); // 等待下一次读取...
}
} catch (IOException InterruptedException e) {
();
break;
}
}
}
}
}
```
