[英]Connect two Android devices using bluetooth programmatically
我正在做一個藍牙項目,我想用blutooth programaticaly連接兩個設備。
我遵循tf developer.android.com的指南和代碼。任何人都可以幫我解決這個問題嗎?這是我試過的代碼。
任何人都可以告訴我構造函數從哪里接收設備對象?
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();
} catch (IOException e) { }
}
}
Thanks inadvance
這是我完成任務的一些代碼。
/**
* 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");
}
要使用上述代碼,設備必須已配對。
