抱歉我的英语不好..所以..我有这段代码:
void inputthread() {
final Handler handler = new Handler();
final int misurazione[]={0};
final byte delimiter = 65; //This is the ASCII code for a newline character
stopWorker = false;
readBufferPosition = 0;
readBuffer = new byte[1024];
workerThread = new Thread(new Runnable() {
public void run() {
while(!Thread.currentThread().isInterrupted() && !stopWorker)
{
try
{
int bytesAvailable = mmInputStream.available();
if(bytesAvailable > 0)
{
byte[] packetBytes = new byte[bytesAvailable];
mmInputStream.read(packetBytes);
for(int i=0;i<bytesAvailable;i++)
{
byte b = packetBytes[i];
if(b == delimiter)
{
byte[] encodedBytes = new byte[readBufferPosition];
System.arraycopy(readBuffer, 0, encodedBytes, 0, encodedBytes.length);
String data = new String(encodedBytes, "US-ASCII");
readBufferPosition = 0;
try {
misurazione[0] = Integer.parseInt(data);
handler.post(new Runnable()
{
public void run()
{
txtaggiorna.setText(misurazione[0]);
}
});
} catch(NumberFormatException nfe) {}
}
else {
readBuffer[readBufferPosition++] = b;
}
}
}
}catch (IOException ex)
{
stopWorker = true;
}
}
}
});
workerThread.start();
}
Android从仅包含数字字符串的arduino接收字节,我想将其转换为整数,但是Integer.parseInt(数据)不起作用,我不知道为什么......
答案 0 :(得分:0)
String data = new String(encodedBytes.toString(), "US-ASCII");
