public interface MyInterface { public void myMethod(boolean result);}public class AsyncConnectTask extends AsyncTask<Void, Void, Boolean> { private MyInterface mListener; public AsyncConnectTask(Context context, String address, String user, String pass, int port, MyInterface mListener) { mContext = context; _address = address; _user = user; _pass = pass; _port = port; this.mListener = mListener; } @Override protected Boolean doInBackground(Void... params) { .... return result; } @Override protected void onPostExecute(Boolean result) { if (mListener != null) mListener.myMethod(result); }}AsyncConnectTask task = new AsyncConnectTask(SiteManager.this, _address, _username, _password, _port, new MyInterface() { @Override public void myMethod(boolean result) { if (result == true) { Toast.makeText(SiteManager.this, "Connection Succesful", Toast.LENGTH_LONG).show(); } else { Toast.makeText(SiteManager.this, "Connection Failed:" + status, Toast.LENGTH_LONG).show(); } }});task.execute();如果myMethod从onPostExecute内部代码调用，它将在UI线程上运行。否则，你需要通过
Handler
