我正在尝试创建一个国际象棋应用程序，我从蓝牙获取移动信息，然后我需要将它发送到位于核心类的方法。此外，我需要在单击核心类的按钮时启动AndroidLauncher中的函数。
AndroidLauncher：
public class AndroidLauncher extends AndroidApplication {
public static final int CONNECTION_TIMEOUT=10000;
public static final int READ_TIMEOUT=15000;
BluetoothSocket mmSocket;
BluetoothDevice mmDevice = null;
final byte delimiter = 33;
int readBufferPosition = 0;
public void sendBtMsg(String msg2send){
//UUID uuid = UUID.fromString("00001101-0000-1000-8000-00805f9b34fb"); //Standard SerialPortService ID
UUID uuid = UUID.fromString("94f39d29-7d6d-437d-973b-fba39e49d4ee"); //Standard SerialPortService ID
try {
mmSocket = mmDevice.createRfcommSocketToServiceRecord(uuid);
if (!mmSocket.isConnected()){
mmSocket.connect();
}
String msg = msg2send;
//msg += "\n";
OutputStream mmOutputStream = mmSocket.getOutputStream();
mmOutputStream.write(msg.getBytes());
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
@Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
MyGdxGame game = new MyGdxGame();

initialize(new MyGdxGame(), config);
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
final class workerThread implements Runnable {
private String btMsg;
public workerThread(String msg) {
btMsg = msg;
}
public void run()
{
sendBtMsg(btMsg);
while(1 == 1) {
while (!Thread.currentThread().isInterrupted()) {
int bytesAvailable;
boolean workDone = false;
try {
final InputStream mmInputStream;
mmInputStream = mmSocket.getInputStream();
bytesAvailable = mmInputStream.available();
if (bytesAvailable > 0) {
byte[] packetBytes = new byte[bytesAvailable];
byte[] readBuffer = new byte[1024];
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);
final String data = new String(encodedBytes, "US-ASCII");
readBufferPosition = 0;
//The variable data now contains our full command

break;
}
}
} catch (IOException e) {

}
}
}
}
};
// end light off button handler
if(!mBluetoothAdapter.isEnabled())
{
Intent enableBluetooth = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBluetooth, 0);
}
Set<BluetoothDevice> pairedDevices = mBluetoothAdapter.getBondedDevices();
if(pairedDevices.size() > 0)
{

{
if(device.getName().equals("raspberrypi")) //Note, you will need to change this to match the name of your device
{
Log.e("Aquarium",device.getName());
mmDevice = device;
break;
}

我需要做的是在AndroidLauncher handler.post(new Runnable() {部分代码中从蓝牙获取数据时调用movefig方法。
答案 0 :(得分：0)
将movefig()公开MyGdxGame公开，以便您可以从任何套餐中进行访问。
MyGdxGame gdxGame;
@Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
gdxGame = new MyGdxGame();
View gameView = initializeForView(gdxGame, config);
setContentView(gameView);
}
现在您已引用MyGdxGame，您可以在movefig()课程内拨打AndroidLauncher。
您需要interfacing通过core module致电android module
在core模块
public interface Service {
void doSomeThing();
}
在AndroidLauncher class
public class AndroidLauncher extends AndroidApplication implements Service {
MyGdxGame gdxGame;
@Override
protected void onCreate (Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
AndroidApplicationConfiguration config = new AndroidApplicationConfiguration();
gdxGame = new MyGdxGame(this);
View gameView = initializeForView(gdxGame, config);
setContentView(gameView);
}
@Override
public void doSomething() {
//do what you want
}
...
}
保留对来自平台的Service的引用，以便创建MyGdxGame的参数化构造函数
public class MyGdxGame extends ApplicationAdapter {
Service service;
public MyGdxGame(Service service){
this.service=service;
}
...
}
