通过蓝牙编程连接两台Android设备
我正在做一个蓝牙项目,我想用blutooth编程连接两个设备 我遵循tf developer.android.com的指导原则和代码。有人能帮我解决这个问题吗?以下是我尝试过的代码 有人能告诉我构造函数从哪里接收设备对象吗通过蓝牙编程连接两台Android设备,android,Android,我正在做一个蓝牙项目,我想用blutooth编程连接两个设备 我遵循tf developer.android.com的指导原则和代码。有人能帮我解决这个问题吗?以下是我尝试过的代码 有人能告诉我构造函数从哪里接收设备对象吗 private class ConnectThread extends Thread { private final BluetoothSocket mmSocket; private final BluetoothDevice mmDevic
private class ConnectThread extends Thread {
private final BluetoothSocket mmSocket;
private final BluetoothDevice mmDevice;
<!-- can anyone tell me from where device object comes here --!>
public ConnectThread(BluetoothDevice device) {
// Use a temporary object that is later assigned to mmSocket,
// because mmSocket is final
BluetoothSocket tmp = null;
mmDevice = device;
// Get a BluetoothSocket to connect with the given BluetoothDevice
try {
// MY_UUID is the app's UUID string, also used by the server code
tmp = device.createRfcommSocketToServiceRecord(MY_UUID);
} catch (IOException e) { }
mmSocket = tmp;
}
public void run() {
// Cancel discovery because it will slow down the connection
mBluetoothAdapter.cancelDiscovery();
try {
// Connect the device through the socket. This will block
// until it succeeds or throws an exception
mmSocket.connect();
} catch (IOException connectException) {
// Unable to connect; close the socket and get out
try {
mmSocket.close();
} catch (IOException closeException) { }
return;
}
// Do work to manage the connection (in a separate thread)
manageConnectedSocket(mmSocket);
}
/** Will cancel an in-progress connection, and close the socket */
public void cancel() {
try {
mmSocket.close();

Thanks inadvance

下面是我完成任务的一些代码
/**
* Searches the list of paired devices for the device. Returns
* if found, throws Exception otherwise.
*
* @param sTargetDeviceName
* @return BluetoothDevice
*/
private BluetoothDevice findDevice(String sTargetDeviceName)
throws Exception {
BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();
Set<BluetoothDevice> devices = adapter.getBondedDevices();
for (BluetoothDevice device : devices) {
String sDeviceName = device.getName().trim();
if (sDeviceName.startsWith(sTargetDeviceName)) {
return device;
}
}
throw new Exception("Device " + sTargetDeviceName + " not found");
}
/**
*在配对设备列表中搜索设备。返回
*如果找到,则抛出异常。
*
*@param sTargetDeviceName
*@返回蓝牙设备
*/
专用蓝牙设备findDevice(字符串sTargetDeviceName)
抛出异常{
BluetoothAdapter=BluetoothAdapter.getDefaultAdapter();
Set devices=adapter.getBondedDevices();
用于(蓝牙设备:设备){
字符串sDeviceName=device.getName().trim();
if(sDeviceName.startsWith(sTargetDeviceName)){
返回装置;
}
}
抛出新异常(“设备”+sTargetDeviceName+“未找到”);
}
要使用上述代码,设备必须已配对
