Question

当点击activity_main（button1）上的按钮时，我想测试ChatClientService。

在onStartCommand方法中，我想运行一个使用innerclass作为runnable的线程。这是错误的：意图工作（日志显示aaaaa），它进入run方法（日志显示aaaaa），但我没有设法进入内部类。有任何想法吗？（对不起日志）

ChatClientService.java

public class ChatClientService extends Service {

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
  //TODO do something useful

    new Thread( new Runnable() {
        @Override
        public void run() {
            Log.i("aaaaaaaaaaaaaaaaaaaa","aaaaaaaaaaaaaaaaaaaa");
        }
    }).start();
    return Service.START_NOT_STICKY;
}

@Override
public IBinder onBind(Intent arg0) {
    // TODO Auto-generated method stub
    return null;
}

public class ChatClient implements Runnable {

    private BufferedWriter bw;
    private BufferedReader br;
    private boolean running;

    public void halt() {

        Log.i("DDDDDDDDDDDDDDDDDD","DDDDDDDDDDDDDDDDDD");
        running = true;
        try {
            bw.close();
            bw = null;
            br.close();
            br = null;
        } catch (IOException e) {
            Log.i("EEEEEEEEEEEEEEEEE","EEEEEEEEEEEEEEEEEEE");
        }       
    }
    @Override
    public void run() {
        Log.i("HHHHHHHHHHHHHHH", "HHHHHHHHHHHHHHH");
        try {
            running = true;
            Socket s = new Socket("<your pc ip>", 9999);
            this.br = new BufferedReader(new InputStreamReader(s.getInputStream()));
            this.bw = new BufferedWriter(new OutputStreamWriter(s.getOutputStream()));
            String in = null;
            while(running  && (in = br.readLine()) != null) {
                Log.i("CHATCLIENT RECV ", in);
            }
        } catch (UnknownHostException e) {
            e.printStackTrace();
            Log.i("FFFFFFFFFFFFFFFF","FFFFFFFFFFFFFFF");
        } catch (IOException e) {
            e.printStackTrace();
            Log.i("GGGGGGGGGGGGG","GGGGGGGGGGG");
        }           
    }
}
}

MainActivity.java

public class MainActivity extends Activity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

public void TestChat(View v){
    Log.i("cccccccccccccccccccccccccc","cccccccccccccccccccccc");
    startService(new Intent(getApplication(), ChatClientService.class));
}
}

试试这个......

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    super.onStartCommand(intent, flags, startId);
    new Thread(new ChatClient()).start();
    return START_NOT_STICKY;
}

如何运行使用内部类的线程？
