android – 等待使用ProgressDialog执行AsyncTask

在AsyncTask中启动繁重的进程,但是在完成AsyncTask之后要执行的任何代码都将它放在一个单独的公共方法中.现在,一旦你完成了在onPostExecute()中单独创建的方法的重过程调用.

所以psuuedo代码看起来像这样,

class main extends Activity {

    class Something extends AsyncTask<String,Integer,String> {

        protected void onPreExecute() {
            // Start your progress bar...
        }

        protected String doInBACkground(String... params) {
            // Do your heavy stuff...
            return null;
        }

        protected void onPostExecute(String result) {
            // close your progress dialog and than call method which has
            // code you are wishing to execute after AsyncTask.
        }
    }

}

希望这会有所帮助,

祝好运！
