Android学习：AsyncTask方案解决UI线程阻塞

post方式能解决UI线程阻塞问题，但是代码的可读性较差。

一：看程序

二：定义AsyncTask

private class testTask extends AsyncTask<String, Void, Integer> {protected Integer doInBackground(String... arg0) {try {Thread.sleep(5000);} catch (InterruptedException e) {e.printStackTrace();}int sum = 10;return 10;}protected void onPostExecute(Integer sum) {button2.setText("" + sum);}}

执行task

new testTask().execute();
