Answer 1

public class connectTask extends AsyncTask<String, String, TCPClient> {

        @Override
        protected TCPClient doInBackground(String... message) {

            // we create a TCPClient object and
            mTcpClient = new TCPClient(new TCPClient.OnMessageReceived() {
                @Override
                // here the messageReceived method is implemented
                public void messageReceived(String message) {
                    // this method calls the onProgressUpdate
                    publishProgress(message);
                }
            });
            mTcpClient.run();
            return null;
        }

        @Override
        protected void onProgressUpdate(String... values) {
            super.onProgressUpdate(values);
            //servermsg1 += values[0];
            //writedatabase(servermsg1);
            // in the arrayList we add the messaged received from server
             arrayList.add(values[0]);
            // notify the adapter that the data set has changed. This means that
            // new message received
            // from server was added to the list
             mAdapter.notifyDataSetChanged();
        }
    }

调用此方法调用asynctask

connectTask connect = new connectTask();
        connect.execute("");
