通过线程来处理耗时的操作：比如从服务器获取数据

public void doInHandler(final int type, final String msg) {handler.post(new Runnable() {public void run() {switch (type) {case 1:Toast.makeText(getApplicationContext(), msg,Toast.LENGTH_SHORT).show();break;case 2:dealinthread();break;}}});}private void dealinthread() {//访问服务器}
