我有一个与蓝牙目标设备通信的系统，该设备在Android系统上的动作上发送命令字符串，并在时钟序列上接收来自目标的数据。传出数据没有明显的问题，但我在蓝牙服务例程和呈现给UI的片段之间间歇性地丢失数据。
Android应用程序内的通信路径是：
代码的相关部分是：
/*
* This thread runs during a connection with a remote device.
* It handles all incoming and outgoing transmissions.
*/
private class ConnectedThread extends Thread
{
private static final byte enq = 5;
private final BluetoothSocket mmSocket;
private final InputStream mmInStream;
private final OutputStream mmOutStream;
public ConnectedThread(BluetoothSocket socket, String socketType)
{
if (D) Log.d(TAG, "498 - create ConnectedThread: " + socketType);
mmSocket = socket;
InputStream tmpIn = null;
OutputStream tmpOut = null;
// Get the BluetoothSocket input and output streams
try
{
tmpIn = socket.getInputStream();
tmpOut = socket.getOutputStream();
}
catch (IOException e)
{
Log.e(TAG, "510 - temp sockets not created", e);
}
mmInStream = tmpIn;
mmOutStream = tmpOut;
}
public void run()
{
if (D) Log.i(TAG, "518 - Begin mConnectedThread");
int bytes;
int dataCount = 0;
// Keep listening to the InputStream while connected
while (true)
{
try
{
// Read from the InputStream
byte[] inBuffer = new byte[128];
int bufferPtr = 0;
bytes = mmInStream.read(inBuffer);
if (D) Log.e(TAG, "530 - InStream length = : " + bytes + " bytes: ");
for (int i=0; i<bytes; i++)
{
if (D) Log.e(TAG, "533 - inBuffer[" + i + "] - " + Integer.toHexString(inBuffer[i] & 0xFF) + " - " + (char)inBuffer[i] );
}
while(bufferPtr<bytes)
{
// if (D) Log.e(TAG, " 538 - dataIn = " + dataIn + " : ctlIn = " + ctlIn);
if (!dataIn && !ctlIn )
{
if (inBuffer[bufferPtr] == enq) // Is it a new data message?
{
if (D) Log.e(TAG, "543 - New data stream in" );
dataIn = true;
Arrays.fill(dataBuffer,(byte)0);
bufferPtr++;
dataCount = 0;
}
else // Must be a new control command
{
// It's a control message
}
}
if (dataIn && (bufferPtr<bytes))
{
if (dataCount<dataItems)
{
dataBuffer[dataCount] = inBuffer[bufferPtr];
dataCount++;
bufferPtr++;
if(D) Log.e(TAG, "565 - dataBuffer[" + (dataCount-1) +"] - " + Integer.toHexString(dataBuffer[dataCount-1] & 0xFF));
}
else
{
dataIn = false;
for (int i=0; i<dataBuffer.length; i++)
{
if (D) Log.e(TAG, "573 - DataInArray[" + i + "] = " + Integer.toHexString(dataBuffer[i] & 0xFF));
}
mHandler.obtainMessage(BaseActivity.DATA_MESSAGE_IN, dataBuffer.length, -1, dataBuffer).sendToTarget();
if (D) Log.e(TAG, "576 - " + dataItems + " bytes received. Data stream sent to host ##" );
}
}
if (ctlIn)
{
// It'a control message
}
}
// Send the obtained bytes to the UI Activity
}
catch (IOException e)
{
Log.e(TAG, "604 - disconnected", e);
connectionLost();
// Start the service over to restart listening mode
BtService.this.start();
break;
}
}
}
基本活动中的处理程序代码为：
@Override
public void handleMessage(Message msg)
{
if(D) Log.e(TAG, "427 - << Handler message received: >> " + msg.what);
switch (msg.what)
{
case MESSAGE_STATE_CHANGE:
// Deal with state change
break;
case MESSAGE_OUT:
// Deal with outgoing message
break;
case CONTROL_MESSAGE_IN:
// Deal with incoming control message
break;
case DATA_MESSAGE_IN:
dataIn = (byte[]) msg.obj;
int dataMsgLength = msg.arg1;
if (D) Log.e(TAG, "490 - Received data stream: length = " + msg.arg1 + " bytes:");
for (int i=0; i<dataMsgLength; i++)
{
if (D) Log.e(TAG, "494 - DataIn[" + i + "] - " + Integer.toHexString(dataIn[i] & 0xFF));
}
Hmi2Fragment.updateDisplay(dataIn);
break;
case MESSAGE_DEVICE_NAME:
// save the connected device's name
break;
case MESSAGE_TOAST:
// Deal with Toast
break;
case FILE_SELECTED:
// Deal with file
break;
}
}
};
然后将接收到的数据数组传递给Fragment Hmi2，在那里显示它。这个代码是： //主机活动调用的方法，用于更新显示的数据。 public static void updateDisplay（byte [] inDataBytes） { for（int i = 0; i
if ((k & 2) != 0) bst[1].setImageLevel(1);
else bst[1].setImageLevel(0);
bst[1].invalidate();
}
else
{
for (int j=0; j<8; j++)
{
int indNo = mapIn[i-1][j];
if ((indNo == 0) || (indNo >0))
{
if ((k & (1 << j)) != 0) ind[indNo].setImageLevel(1);
else ind[indNo].setImageLevel(0);
ind[indNo].invalidate();
}
}
}
}
问题在于，当我运行应用程序并使用Logcat跟踪通过管道的数据流时，数组并没有像我期望的那样相互跟踪。
良好转移的一个例子是：

在我看来，似乎某个地方存在同步问题，但我看不出任何明显的数据消失方式。
编辑：它确实是一个同步问题 - 删除arrays.fill命令可以在更新字节数组时停止问题，而不是清除和重新加载。 欢迎任何建议！
