我正在使用一种方法从蓝牙接收值。
当我使用Log.e打印接收的值时,可以查看数据,但是当我尝试比较数据时,条件失败。
我正在尝试将当前数据与1和0进行比较,即使接收到的数据从0变为1,我也会继续接收0。我试图从“==”更改为“相等”,但它仍无法正常工作
我做错了什么?
public void beginListenForData()
{
final Handler handler = new Handler();
final byte delimiter = 10; //This is the ASCII code for a newline character
stopWorker = false;
readBufferPosition = 0;
readBuffer = new byte[200];
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);
data = new String(encodedBytes, "US-ASCII");
readBufferPosition = 0;
handler.post(new Runnable()
{
public void run()
{
if (data == "1") {
anyObject = true;
Log.e("Val 1", data);
} else if(data == "0"){
anyObject = false;
Log.e("Val 0", data);
}
}
});
}
else
{
readBuffer[readBufferPosition++] = b;
}
}
}
}
catch (IOException ex)
{
stopWorker = true;
}
}
}
});
workerThread.start();
}
谢谢。
