如何停止AsyncTask类中的活动

Question

  

我试着把finish（）方法用来阻止堆栈。但它给了我语法错误。我可以停止堆栈。谢谢提前。

 private class getNewMessages extends AsyncTask<ApiConnector, Long, JSONArray> {


            @Override
            protected JSONArray doInBackground(ApiConnector... params) {
                try {
                    JSONArray array = params[0].getMessage(name, password);
                    // String [] array=new String[10];

                    if (array.length() > 0) {
                        Intent nextScreen = new Intent(getApplicationContext(), bussiness.class);
                        nextScreen.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP |Intent.FLAG_ACTIVITY_NEW_TASK);
                        startActivity(nextScreen);

                    }
                }catch (Exception e)
                {
                    Toast.makeText(getApplicationContext(),"Wrong Credintials", Toast.LENGTH_SHORT).show();
                }
                return null;
            }

            @Override
            protected void onPostExecute(JSONArray result) {


            }


        }

Answer 1

将代码转移到onPostExecute回调

DatagramSocket

Answer 2

尝试使用(Activity)mContext).finish();或finish();
