对于单片机蓝牙连接的过程中，搜索过程虽然省略了，但是连接仍然是费时间的，所有我把它单独写了一个进程来实现，以免出现黑屏的现象，同时程序里我还对bundle传值，Activity间跳转方式进行了修改。

/*

private class ConnectThread implements Runnable {
@Override
public void run() {

Message message = new Message();

BluetoothDevice device = _bluetooth.getRemoteDevice(address);

try {
_socket = device.createRfcommSocketToServiceRecord(MY_UUID);
} catch (IOException e) {
try {
message.what = FAIL;
_socket.close();
_socket = null;

} catch (IOException e1) {
e1.printStackTrace();
}
Log.e("ceshi", "ON RESUME: Socket creation failed.", e);
}

_bluetooth.cancelDiscovery();

try {
_socket.connect();

message.what = SUCCESS;
} catch (IOException e) {
try {
message.what = FAIL;
_socket.close();
_socket = null;
} catch (IOException ee) {
message.what = FAIL;
}

return;
}

connectHandler.sendMessage(message);
}
}

/*

private class ConnectHandler extends Handler {
@Override
public void handleMessage(Message msg) {
// super.handleMessage(msg);

switch (msg.what) {
case 0:
myToast(R.string.link_fail);

break;
case 1:
Toast.makeText(getApplicationContext(), "连接" + addressName + "||" + address + "成功！", Toast.LENGTH_SHORT).show();

break;

case 2:
myToast(R.string.not_found_bluetooth);
}
}
}追问我不是要连接我是连接到这个蓝牙后发送数据过后，断开这个蓝牙连接
